Item Fertilizer Effects on Panicle Characteristics, Grain Weight and Yield of Upland Rice in Lowlands of Taita Taveta, Kenya(International Journal of Plant & Soil Science, 2022-07-11) Milela, R.M.; Kambura, A.K.; Maghenda, M.; Gacheru, J.; Maghanga, J.; Kimani, J.; Mcharo, M.; Taita Taveta University ; Taita Taveta County Government, Livestock, Fisheries and Irrigation ; Kenya Agricultural and Livestock Research OrganizationThis study was done at Mlughi Agricultural demonstration farm in Bura, Taita Taveta County-Kenya to test upland rice varietal performance and di-ammonium fertilizer effects on panicle characteristics and yield parameter. A randomized complete block design (RCBD) was used with seven upland rice varieties and three fertilizer levels. The treatments were replicated thrice to give a total of 63 treatment combinations or plots. The experiment was carried out for two seasons (short rains from October to December 2018 and long rains from March to May 2019). The upland rice varieties included 17KH09010014B, 17KH09010093B, AT 058, China Hybrid, NERICA 1, NERICA 4, and NERICA 10. The fertilizer treatments were di-ammonium phosphate fertilizer (DAP), farm yard manure (FYM), and a control of no fertilizer. Topdressing was done at the flowering stage with NPK fertilizer. Data collected included plant height, number of leaves, tiller number, panicle length, spikelets count per panicle, grain yield ha-1 and weight of 1000 grains. The data were subjected to multivariate analysis of variance (MANOVA) using R version 3.6.1 program and Tukey’s HSD test, p ≤ 0.05 was used to separate the significant means. The results showed that there was significant influence (p = 0.0001) of overall seasonal, treatment and variety on the yield of rice grains in tonnes per hectare. The 2018 season had the lowest tonnage compared to the 2019 season. Crops under the control treatment yielded the least tonnage per hectare while the DAP treated fields yielded the highest in both seasons. NERICA 4 was the highest yielding variety while AT 058 was the least yielding among the treatments in both seasons. It was therefore concluded that the application of DAP and FYM significantly increased rice productivity. Farmers are therefore encouraged to carry out soil fertility testing occasionally and to plant NERICA varieties.Item Factors That Influence Adoption of New Improved Wheat Varieties by Farmers in Nakuru and Narok, Kenya(European Journal of Agriculture and Food Sciences, 2022-04-14) Gichangi, A.; Mukhebi, A.; Murithi, F.; Kenya Agricultural and Livestock Research Organization (KALRO) ; Jaramogi Oginga Odinga University of Science and Technology (JOOUST)This study examines the factors that influence the adoption of new improved wheat varieties (NIWV) by wheat farmers in Nakuru and Narok counties in Kenya. Cross-sectional data from 344 randomly selected wheat farmers from the Njoro and Rongai sub-Counties in Nakuru County; and Narok South and Narok North sub-counties in Narok County, Kenya were investigated. Probit model was run to estimate the factors influencing the adoption rate of improved new wheat varieties. Results derived from model estimates indicate that farmers' adoption of improved wheat varieties in the study area is positive due to education, availability of information, off-farm income, distance to inputs and produce markets, and exposure to extension advice services and access to credits. The study recommends that the public and private sectors promote access to advisory services to improve the dissemination of certified wheat seeds to farmers through training, workshops, and seminars.Item Returns to Wheat Research, Varietal Adoption, and Turnover Rates and Wheat Production Risks in Kenya(Asian Journal of Agricultural Extension, Economics & Sociology, 2022-04-01) Gichangi, A.; Mukhebi, A.; Murithi, F.; Jaramogi Oginga Odinga University of Science and Technology (JOOUST) ; Kenya Agricultural and Livestock Research OrganizationA lot of public funds have been used for investment in wheat research in Kenya. The concern is whether it is worthwhile to continue investing. The problem is there is no information on what returns to investments have been achieved to guide the continued allocation of resources to wheat research. To address this problem, this paper seeks to estimate returns to wheat research investments in Kenya, and the wheat varietal adoption and turnover rates that influence it. The Benefit-Cost Analysis (BCA) model was applied to estimate the returns to wheat research, in terms of three indicators: Benefit-Cost Ratio (BCR), Net Present Value (NPV), and Internal Rate of Return (IRR). Adoption index was used to estimate wheat varietal adoption rates (VAR). The area-weighted average variety age (WAVA) was used to estimate the varietal turnover rate (VTR). The Five-Point Likert scale model was used in assessing production risks. A field survey was used for data collection in selected wheat-producing Counties of Kenya. The results generated were a BCR of 1.47, an NPV of 23.31 million Kenya Shillings, an IRR of 41%. The VAR was 42% and VTR was 15.65 years. The main wheat production risks were output price fluctuations, seed availability, pests, and diseases in that order of ranking. In conclusion, return on investments in wheat research is positive, though relatively low compared to other countries, largely due to low varietal adoption and turnover rates and prevalence of high production risks. The recommendation is that to improve returns to wheat research in Kenya, varietal adoption and turnover rates should be improved and production risks should be minimized or eliminated.Item Farmers’ Preference for Rice Traits: Insights from Farm Surveys in Busia County, Kenya(International journal of Agriculture, 2022-03-16) Danda, K.; Kimani, J.; Kang, K. H.; Kenya Agricultural and Livestock Research Organization, Industrial Crops Research Institute ; AfricaRice Center, National Institute of Crop Science - Rural Development Administration of Korea (RDA)Purpose: A cross-sectional survey was designed to study farmers' preferences for rice varieties in Busia County, Kenya. Methodology: The survey used a multi-stage sampling technique for site selection and a purposive strategy for rice growers/producers. Data was collected from key rice value chain stakeholders including farmers, extension service providers, local leaders and hoteliers using focus group discussions by use of guiding checklists and a structured questionnaire. A total of 26 key informants and 62 individual respondents in the categories mentioned were interviewed. Descriptive analysis was done along with cross-tabulations to establish associations. Findings: Results indicated that rice was a significantly important farm enterprise among the respondents with a higher land allocation of 2.04 acres followed by maize with 1.14 acres. Seed sources were mainly traditional with fellow farmers being instrumental in seed sharing at cost (59.7% buying form other farmers) followed by free issues (19.4% getting free from other farmers). Research as a seed source lagged at 8.1%. Variety choice was said to be dictated by high yield, early maturity and one thousand seed weight by 80.6%, 77.4% and 40.3% respectively. These attributes were also ranked as first, second and third positions respectively. Rice production followed traditional patterns as 60% of producers/farmers depended on a farmer-to-farmer seed system over all the production periods. There also lacked structures and efforts to upscale rice production and therefore this paper recommends formulation and direction of concerted efforts towards on-farm participatory research and formation of social networks for rice production and marketing information. Contribution to theory, practice and policy: The results give impetus to conclude that farmers know which traits are of priority in variety selection. Going by farmers’ perceptions simply means responding to consumer demand for quality in rice production. The study also demonstrated enormous potential for rice production as demonstrated by the will of the farmers to allocate 45% of their land parcels to rice production. It also brought out that the fact that certified rice seeds are rarely used and therefore, there is urgent need to establish seed systems and distribution pathways in order to improve on yields as well as quality of paddy hence more income to farmers and other rice value chain players. The concepts of field demonstrations and on-farm participatory research need to be up-scaling for enhanced transformation of rice production landscape in the region.Item Effect of Ridging and Intercropping on Sorghum Productivity in Arid and Semi-Arid Lands of Eastern Kenya(African Crop Science Journal, 2022-02-28) Musyimi, D.; Ouma, E.O.; Auma, E.O.; Too, E.J.; Ngode, L.; Kamau, C.K.; Gudu, S.; University of Eldoret ; Rongo University ; Kenya Agriculture and Livestock Research OrganizationSoil moisture deficit is a key constraint to sorghum (Sorghum bicolor) productivity in arid and semi-arid lands globally. The objective of this study was to determine the effect of ridging and sorghum-bean intercropping (additive system) on soil moisture conservation and sorghum productivity. Sorghum (gadam) was grown either as a sole crop or intercropped with two bean (Phaseolus vulgaris L.) varieties (KATx56 and KAT B1), under two types of ridging (open ridges and tied ridges), and a control without ridges for two years. The study was set up in split plot arrangement, in a randomised complete block design, at the Kenya Agricultural and Livestock Research Organization, Kiboko, in 2019 and 2020. There was no significant interaction between ridging and intercropping. Soil moisture content increased by 11-26% due to ridging; and decreased by-11 and-7% due to sorghum-KAT B1 and Sorghum-KAT X56 intercropping, respectively. Higher moisture content due to ridging was attributed to formation of basin-like structures, which increased water harvesting and infiltration compared to the no ridges where surface run-off was predominant. The highest moisture content was attained on sole bean, followed by sole sorghum and then sorghum/bean intercropping. The decrease in moisture content in intercrops of sorghum/bean relative to their specific sole crops was attributed to higher crop density, which reduced crop spacing, thus triggering competition for available soil moisture. The highest sorghum grain and equivalent yields were obtained in the ridged plots. Intercropping resulted into decrease in sorghum grain yield, but led to increase in sorghum equivalent yield (SEY) and Land Equivalent Ratio (LER). The results show that both ridging and intercropping are suitable for higher water use efficiency and land productivity in ASALs of Kenya.Item Effect of Intercropping Finger Millet [Eleusine Coracana (L.) Gaertn.] With Desmodium Intortum on Striga Hermonthica Emergence across Planting Seasons(African Journal of Education, Science and Technology,, 2017) Makete, N. N.; Gohole, L. S.; Opile, W. R.; Oduori, C. A.Striga hermonthica is a major constraint affecting finger millet production in western Kenya. Yield potentials of improved finger millet varieties remain unexploited due to susceptibility to Striga. Previous studies have shown the value of intercropping maize with Desmodium spp. in efforts to control Striga. Recent studies have shown related responses when a local finger millet variety was intercropped with Desmodium spp. This study investigated the effect of intercropping Green leaf Desmodium (Desmodium intortum) with finger millet on Striga emergence and finger millet yield across two planting seasons. Trials were set up on-station at Kenya Agricultural and Livestock Research Organization’s Alupe centre (KALRO-Alupe) and on-farm at Okiludu in Teso South during the 2013 short rains and 2014 long rains seasons. Results in this study indicated no consistent evidence to show that intercropping finger millet varieties with Desmodium intortum suppressed Striga at the two sites during the two seasons tested. However, lower Striga counts were observed during the long rains season (35.9 Striga plants/plot) while higher Striga counts (151.4 Striga plants/plot) were observed during the short rains season. Finger millet yield differed significantly across planting seasons where higher yield (1.1 t/ha) was observed during the long rains season and lower yield (0.6 t/ha) during the short rains season. This gave a clear indication that strigolactones production may have differed across rainfall seasons. Farmers in Striga infested Alupe and Teso sub-counties are advised to consider planting finger millet during the long rains season when Striga emergence is low for better yields.Item Farmers’ Demonstrate Rationality and Transitivity in Variety Choice: Empirical Evidence From two Rice Growing Niches in Coastal Kenya(International Journal of Agriculture, 2021) Kengo, M.; Kimani, J.; Sang-Bok, L.; Kenya Agricultural and Livestock Research Organization ; Africa Rice Training CenterPurpose: A cross-sectional survey was designed to study farmers’ preference and choice framework for rice varieties in Kwale and Taita-Taveta counties of coastal lowland Kenya. Methodology: The survey used a multi-stage sampling technique; systematic selection for the study counties/niches, a purposive sampling approach for the study population (rice growers only) and a systematic random sampling for the respondents on an n th occurrence. Data was collected with the aid of a semi-structured questionnaire and key informant interviews from key rice value chain actors; including farmers as producers as well as consumers and agricultural extension service providers (AESPs) and other stakeholders. A total of 137 individual respondents were interviewed using the semi-structured questionnaire while the key informant interviews engaged a total of 29 AESPs. Data analysis focused on exploring on the varieties that farmers grew and whether they had a criteria or pattern for choosing the varieties to grow and seed source. Findings: Results confirmed that the Kwale rice growing niche had a higher rice variety diversity (more than 12 varieties) while Taita-Taveta had only around seven (7) common varieties. Rice was more traditionally grown in Kwale with low acreage and low yields compared to Taita-Taveta. Common varieties grown were Pachanga, Supa, Kitumbo, Makonde and Kibawa in Kwale while in Taita-Taveta, Japan, Supa and Hybrid 6444 rice varieties were common (with prevalence rating of 44.8%, 25.4%, 22.4%, 20.9 and 17.9% in Kwale respectively and 55.7%, 54.3% and 18.6% in Taita-Taveta respectively). Varieties grown by farmers in Kwale had a long history of seed recycling and were characterized by low productivity (less than 6, 90-kg bags per acre) and subsistent in nature than in Taita-Taveta. The general picture for variety prevalence in both (Kwale and Taita) growing niches was that farmers mostly relied on traditional (own-preserved, farmer-to-farmer exchange or market) seed systems for the recycled rice varieties. Variety choice by farmers who are both producers and consumers demonstrated a rational and transitive behavior with land resource allocation. Contribution to theory, practice and policy: The study provided evidence of an urgent need for strategic interventions towards improving the production system through on-farm researcher-led demonstrations for superior rice varieties, agronomic practices as well as an input subsidy and sustainable market linkages. Formation of farmer producer groups and strategic facilitation of the groups with rice certified seed and mills are proposed as positive drivers to improving rice marketing and increased productivity.Item Interactive Effects of Tillage Methods and Inorganic Nutrients on Maize and Beans Performance in Embu County, Kenya(AgEcon Search, 2023-02-27) Ogega, S.; Mugwe, J.; Micheni, A.; Kenyatta University ; Kenya Agricultural and Livestock Research Organization - EmbuThe decrease in maize and bean production is a major concern in the food security of the majority of small household farmers in Embu County, Kenya. A farm profile study conducted in the region revealed that the yields of the two crops are low at 1.2 and 0.5 tons/ha against the expected 6.0 and 2.3 tons/ha per season for maize and bean, respectively. The low production is attributed to reliance on conventional farming methods and application of fertilizers majorly NPK based without attention to essential nutrients like Mg, Ca, Zn, B and S despite their demonstrated benefits. Conservation agriculture is an alternative for halting the effects of conventional tillage and leads to an increase in yields and sustaining soil fertility. The purpose of this study was to determine the interactive effect of minimum tillage and conventional tillage and inorganic nutrients on maize and bean crop performance. An on-station trial was conducted for two seasons in one of the research stations at Kenya Livestock Research Organization (KALRO) located in Embu County. The trial was laid in a randomized complete block design with asplit-plot arrangement. Minimum tillage and conventional tillage made up the main plots. Each of the main plots were divided into five sub-plots that were applied with five different inorganic fertilizers that include, NK, NP, KP, NPK and MM. Maize and bean performance data collected included days to flowering, days to physiological maturity, days to tasseling, plant height, number of leaves, cobs, biomass and grain weights. The results of maize crops showed a significant interaction between conservation tillage and a combination of MM which recorded 4.18 tons/ha while the interaction of convention tillage and MM recorded 3.58 tons/ha. The results of bean crops showed a significant interaction between conservation tillage and a combination of MM which recorded 1.98 tons/ha while the interaction of convention tillage and MM recorded 1.78 tons/ha. The increased yields can be explained by the mulch in conservation tillage which ensured moisture availability by reducing evaporation, especially on the dry season during the growth cycle of the maize and bean plant. In addition, the presence of macro and micro-nutrients which are key for the growth of the maize and bean accelerated its growth and development. The study, therefore, recommends the use of a combination of MM in conservation tillage.Item Integrating Inorganic and Organic Fertilizers in Cropping Systems for the Transformation of Maize Productivity in Nakuru County(East African Agricultural and Forestry Journa, 2023) Ooro, P.A.; Mwangi, H.G.; Esilaba, A.O.; Nyongesa, D.; Miriti, J.M.; Okoti, M.; Lusike, W.A.; Githunguri, C.; Thuranira, E.G.; Moraa, L.M.; Luvonga, J.; Osoo, J.O.; Bor, P.K.; Kenya Agricultural Livestock & Research Organization -Njoro (KALRO), Headquaters & KabeteDespite the immense significance of maize (Zea mays L.) for Kenya’s economic prosperity and food security, productivity and production have not significantly increased over time. This is attributed to a number of things, including decreased soil fertility. In order to ascertain the applicability of Integrated Soil Fertility Management (ISFM), a study was carried out between 2016 and 2017 in Nakuru County at the Kenya Agricultural and Livestock Research Organization (KALRO), Njoro Centre, Nakuru County. The treatments were arranged in a split-split plot in a randomized complete block design (RCBD) replicated four times. Soil and water conservation (SWC) and conventional tillage (CT) were allocated to the main plot, the split-plots and fertilizer sources i.e Farm yard manure (FYM), Nitrogen (N) and Phosphoros (P) fertilizers to the split-split plot. Kenya Seed Company maize hybrid (H6213) and Egerton bean variety (Chelalang) were used as test crops. A variety of maize and bean (Phaseolus vulgaris L) characteristics, such as plant stand at germination, plant vigor, days to 50% blooming, days to 50% maturity, plant stand at harvest, number of pods per plant, number of cobs, number of seeds per pod, grain yield, and 100-grain weight, were all recorded. Applying a full rate of inorganic fertilizer resulted in significantly maize yields (P< 0.05) compared to all other fertility management strategies, with the exception of those where a half rate of both inorganic and organic fertilizers was applied. The results further showed that the use of inorganic fertilizer alone considerably increased maize output whether cultivated as a sole crop or an intercrop compared to farmyard manure applied alone or in conjunction with inorganic fertilizer.Item Effect of Tillage, Liming, and Cropping Systems on Maize Yields in Different Agroecological Zones in Kenya(East African Agricultural and Forestry Journal, 2023) Githunguri, C.M.; Esilaba, A.O.; Okoti, M.; Mutuma, E.; Miriti, J.; Nyongesa, D.; Thuranira, E.; Koech, M.; Mutoko, C.; Ndungu, K.; Ooro, P.; Ketiem, P.; Mwangi, H.; Woyengo, V.; Odendo, M.; Ashiono, G.; Kenya Agricultural and Livestock Research Organization(KALRO)Negative effects induced by climate change have contributed to reduced global yields of maize. There is therefore need to endow farmers with innovative and transformative climate smart agriculture technologies to urgently address food insecurity and the realities of climate change in cereal growing regions of Kenya. Technologies have been generated for improved maize and beans production and their impact has not been fully felt. In this study, technologies and innovations on tillage, liming and cropping systems that can improve maize and beans production were evaluated and demonstrated to farmers in different agro-ecological zones in Kenya with the aim of enhancing their adoption. Trials were established at KALRO-Njoro, KALRO-Kakamega, KALRO-Kitale, Baraton University, and Mabanga Agricultural Training Centre, in Nakuru, Kakamega, Trans-Nzoia, Nandi, and Bungoma Counties, respectively. The tillage treatments evaluated included conventional, tied ridges, minimum and zero tillage planted in plots applied with 2 t/ha of lime or without lime. The cropping systems evaluated were maize intercropped with beans or sole cropped maize. A split-split plot design with four replications was used. Results indicated that conventional, tied ridges, and minimum tillage produced higher (P<0.05) yields than the zero tillage with or without lime irrespective of the cropping system in Nakuru, Nandi and Trans-Nzoia Counties. In Nandi, Kakamega and Bungoma Counties, there were no differences (P>0.05) between the four tillage systems.Item The role of Nitrogen in yield Formation and achievement of quality standards in cereals(Cambridge University Press, 1991) Groot, J. J. R.; Spiertz, J. H. J.Grain yield nitrogen content of the grain and nitrogen yield of wheat may vary widely from site to site and from year to year under suboptimal growing conditions, as was shown by Benzian & Lane (1979) in their analysis of wheat production between 1954 and 1973 at Rothamsted. Growth and yield of a crop are the result of the interactive response of the plant to dynamic changes in weather and soil conditions and to the interference of pests diseases and weeds. Recent crop physiological research has resulted in a better understanding of the dependence of crop growth and yield on weather conditions and availability of water and nutrients.Item Divergent Selection for Seedling Root Length and Coleoptile Length in Pearl Millet and Effects on Seedling Emergence Seedling Vigor and Agronomic Traits(Lawrence R, 1993) Riungu, L. (1993), Divergent Selection for Seedling Root Length and Coleoptile Length in Pearl Millet and Effects on Seedling Emergence Seedling Vigor and Agronomic Traits. Mississippi State University. p. 205.A major limitation of pearl millet production in semi-arid areas is poor seedling emergence and establishment . The objectives of this study were to evaluate the effects of selection for seedling roo t length (SRL) and coleoptile length ( CL) on seedling emergence and shoo t hei ght (vigor) , and yield componentsItem Genotype Genotype X Environmental Interaction And Environmental Effects On Yield Yield Components Percent Seed Protein Protein Quality In Cowpeas(Musyoka S M, 1983) Musyoka, S.M.Cowpea, Vigna unguiculata (L.) Walp. is extensively grown in tropical and sub-tropical environments for leaf, immature and mature seeds. It is an important component in the diets of many people and in certain places, it may be the principal source of protein (33). A wide spectrum of local cultivars is grown throughout the producing regions, reflecting consumer preferences and natural selection for types that are comparatively successful under variable and, often adverse climatic and edaphic conditions. There is limited information concerning the genetic variability for yield, yield components and the nutritive value of the edible parts and much still needs to be done to elucidate the role of the genotype x environmental interaction on yield, yield components and quality of cowpea edible parts. Such information is crucial when one considers that production of most crop varieties has been pushed to less and less favorable environments following encroachment of hitherto unsettled areas as a result of population expansion i A need therefore exists for an evaluation of the interrelationships that may exist between yield and important agronomic and quality traits and how these vary with time and location.Item Alectra Weed: A threat to Cowpea(Kenya Agricultural Research Institute, 2010) Kenya Agricultural Research Institute; Karanja, J.; Nguluu, S.Cassava is an important food crop and source of carbohydrate in dry-lands of Eastern Kenya. Production is low due to inadequate soil moisture and lack of technologies. This leaflet provides guidelines on improving productionItem Farmers' Perception and Economic Analysis of Factors Affecting Farm Level Maize Enterprises Performance And Adoption of Agricultural Technological Innovations in Semi Arid South Eastern Kenya(Francis, K.A., 1993) Asambu, F.K.This thesis investigates factors which influence maize enterprise performance and the adoption of an improved maize cultivar, Katumani Composite B (KCB), among subsistence farmers in Kenya's semi-arid south eastem region. Also examined were the perceptions conceming maize production constraints in the region and the advantages and disadvantages of using the cultivar. Empirical analysis was based on cross-sectional farm survey data gathered by means of a questionnaire from a random sample of 96 farmers to whom KCB was available. Maize enterprise performance was measured quantitatively in terms of output (yield) per acre under maize in 1990 whereas adoption was measured qualitatively as a dichotomous variable in terms of adopters and non-adopters. Statistical analysis was based on two dependence models; (1) Multiple Linear Regression and (2) Multiple Logistic Regression. Additionally, descriptive statistics and Chi-square tests of statistical independence were used. Linear regression results suggest that selling price of maize, percentage of land under maize, farming experience, use of inorganic fertilizers, and contact with agricultural extension agents are the most important factors influencing farm-level maize enterprise performance. Interestingly, the Logistic Regression results suggest that the use of hired labour, family size and off-farm employment are the most important factors influencing the adoption of KCB, even though this usage was not a significant factor in the previous results. Further, inadequate rainfall, infertile soils and high cost of inorganic fertilizers were shown to be the major constraints to regional maize production perceived by farmers. Also, farmers perceived early maturity and the high cost of seed to be the main advantage and disadvantage of KCB, respectively. In general, however, farmers in the study region seem to have some contradictory perceptions regarding technical information about KCB.Item Strategic Plan For Cereals In Kenya 1993-2013(Kenya Agricultural Research Institute, 1993/2013) Kenya Agricultural Research InstituteKenya is undergoing change in terms of agriculture, overall economy, and expectations of the population concerning research for facilitating a stable food supply.

The Project was funded by the Netherlands government from 1992 to 1996. The project aimed to document all investigations and research related to agriculture in Kenya undertaken since the end of the last century, especially those items that had not been published. The computerized database now contains around 40,000 records, most containing abstracts or summaries, full bibliographic details, and information about where the documents can be found. We are conscious, however, that many items have not yet been included, especially the earlier material and many consultancy reports produced by foreign and international donors, development, and research organisations. Specialists who read the reviews may be aware of important topics which the reviewer has omitted. If this is the case, we would ask that both the reviewer and KARl's Library and Information Services be informed so that the topic can be included in future revisions. Constant up-date will be required as new research information becomes available with the National Agricultural Research System in Kenya.Item KARI Mwea Research Highlights 2009(Kenya Agricultural Research Institute, 2009) Kenya Agricultural Research InstituteRice and Fibre crops provide employment to majority to rural families in Kenya.
