Cowpea Vigna unguiculata (L.) Walp.) is believed to have originated in Africa where a large genetic diversity of wild types occur throughout the continent, particularly southern Africa, however the greatest genetic diversity of cultivated cowpea is found in West Africa. In Kenya, cowpea is an important source of proteins consumed in many households. It is consumed in the form of whole dried seeds or leaves. Cowpea is grown as a green leafy vegetable mainly in Western Kenya and for grain mainly in the dry lands of Eastern, Coast and Nyanza regions. Cowpea grown as a vegetable requires rich soils and high rainfall. In contrast, cowpea grown for grain requires low rainfall and high temperature. 85% of total area under cowpea production in the eastern region of Kenya, is under intercropping systems with maize and or cassava. Cowpea rank second to beans in importance as vegetable protein food crops. The production is mainly at subsistence level by small-holder farmers with low input. The crop is mainly grown by smallholder farmers. However, pests and diseases are major constraints in cowpea production in Kenya. Accuracy in pest and disease identification are important for proper management making it necessary to build the capacity of extension officers and small holder farmers in pest and disease management in orderto minimize losses.
Cow Pea Trainer of Trainers’ Manual
(Kenya Agricultural and Livestock Research Organization., 2019-04) Macharia, D.; Waithaka, M.; Otipa, M.; Too, A.; Esilaba, A.O.; Nyongesa, D.; Okoti, M.; Mutuma, E.; Kathuku-Gitonga, A.N.; Mutisya, D.; Njunie, M.; Muli, B.; Karanja, J.K.; Wasilwa, L.; Kenya Agricultural and Livestock Research Organization.
Cowpea (Vigna unguiculata (L.) Walp) is an important food and fodder legume crop in the semi-arid tropics. It is grown in 45 countries across the world. An estimated 14.5 million ha of land is planted to cowpea each year worldwide. Sub-Saharan Africa region accounts for about 84% of area as well as production. The world average yield is estimated at about 450 kg/ha. Kenya is among the major cowpea producing countries in Africa. Cowpea is well suited to diverse environments and fit in various cropping systems owing to their wide adaptability, low input requirements, fast growth, nitrogen fixing and weed smothering ability. The majority of cowpea growers are women who grow the crop primarily for household food, but also for sale-an increasing phenomenon in recent years. The typical woman cowpea grower has a small plot, 0.625 to 2.5 acres often intercropped with other cereals such as sorghum, millet and maize. The purpose of this training of trainers’ module is to familiarize master trainers on the cowpea technologies, innovations and management practices (TIMPs) and empower them with knowledge and skills to train farmers’ trainers.
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.
Farm-Level Agricultural Resilience and Adaptation to Climate Change Extension Manual
(Kenya Agricultural and Livestock Research Organization, 2019-12) Okoti, M.; Esilaba, A.O.; Ketiem, P.; Mangale, N.; Muli, B.M.; Nyongesa, D.; Otipa, M.; Mutisya, D.; Too, A.; Njiru, E.; Muthiani, E.; Finyange, P.; Ndanu, A.; Wasilwa, L.; Kenya Agricultural and Livestock Research Organization
Climate change and variability is acknowledged as a global phenomenon with potentially far-reaching implications to many economic sectors. It is characterized by increased recurrence of droughts, floods, rainfall variability (pattern, timing and intensity), increased mean surface temperature and famine that threaten millions of people, crops and livestock systems. The developing countries and the poor in society are highly vulnerable to impacts of climate change despite the minimal contribution (less than 10%) to the annual global carbon dioxide emissions. The increasingly observed weather risks threaten the agricultural production systems and food security conditions for majority of population in Kenya. Farmers who largely practice subsistence farming for livelihoods are characterized by degraded soils, small farm sizes, and low crop yields. Therefore, sustaining farmers’ agricultural growth and minimizing climate related shocks is crucial in building farmers and food production system resilience. Agricultural adaptations to climate change need to be resilient to deal with stresses and disturbances. These adaptations can either be technological, institutional or policy interventions to help farmers build resilience to current and future climate related shocks as well as mitigating greenhouse gas (GHG) emissions.
Farming as a Business Trainer of Trainers Manual
(Kenya Agricultural and Livestock Research Organization (KALRO), 2019-04) Nyongesa, D.; Esilaba, A.O.; Rono, B.; Kavoi, J.; Mwenda, M.; Okoti, M; Kathuku-Gitonga, A.N.; Mutuma, E.; Wasilwa, L.; Kenya Agricultural and Livestock Research Organization (KALRO)
This training manual focuses on building trainees’ capacity in entrepreneurial and management skills through a "learning by doing" approach, eventually leading to, and aiming at developing farmer’s skills and competencies in business while improving their knowledge, changing their attitudes towards farming as a business (FAB) and producing for the market. This will be done through a season-long programme that has been designed to be demand responsive, flexible and practical. It is, however, important to note that farmers learn in small groups, in their own farming environment and at their own pace. The training module intends to master for Training of Trainers (ToTs) constituting government extension personnel and service providers. They will in turn enhance capacity of the farmers under the KCEP-CRAL Programme. The module covers the following broad topics: Farming enterprises; Markets and marketing; Keeping farm records and accounts; Business planning and business plan; Group dynamics; and Gender mainstreaming and communication.
Green Grams Production Training and Extension Manual
(Kenya Agricultural and Livestock Research Organization, 2016-08) Too, A.; Esilaba, A.; Rono, B.; Bett, B.; Gathambiri, C.; Githunguri, C.; Nyongesa, D.; Macharia, D.; Nassiuma, E.; Odoyo, E.; Wayua, F.; Kamau, G.; Mwathi, J.M.; Miriti, J.; Wasilwa, L.; Wanyama, M.; Waithaka, M.; Otipa, M.; Likhayo, P.; Amata, R.; Ochieng, V.
Green grams also known as mung bean, is an erect annual plant which grows to a height of 60-70 cm tall are the more commonly grown in Kenya as compared to black grams. They are common in central and south Nyanza areas, in Machakos and Kitui Counties and at the coast. The two main varieties for the Kenyan market are N26 and KS20 and are differentiated by the colour of seeds. Yellow green grams have bright green seeds while the local green gram seed is small and ripens unevenly. An improved variety (K26) has larger seeds and tends to ripen uniformly, see Table 1. The common names used to refer to green grams are Ndengu or Pojo Ngina. Green grams produces pale yellow flowers borne in clusters of 12–15 near the top of the plant. The flowers develop into cylindrical pods with cylindrical seeds. Pods measure 7.5 cm to 10 cm long and contain 10 to 15 seeds each. Each plant typically produces 30 to 40 pods which turn darker in colour as they mature. The seed colour is in varying shades of yellow to green and black with green and yellow grams being the more common ones in Kenya. The crop is mainly produced by smallholder farmers. However, pests and diseases are major constraints in green grams production in Kenya. Accuracy in pest identification and disease diagnostics are important for proper management of these challenges. It is therefore necessary to build the capacity of extension officers and growers in pest and disease management in order to minimize losses.
Harmonized Fertilizer Recommendations for Pulses in Smallholder Farming Systems of Kenya
(Kenya Agricultural and Livestock Research Organization, 2017-12) Mangale, N.; Kathuku-Gitonga, A.N.; Esilaba, A.O.; Nyongesa, D.; Kenya Agricultural and Livestock Research Organization
Production of pulses in East Africa dates back many years. The pulses (grain legumes) are beans, cowpeas, pigeon peas, green grams, dolichos lablab, chickpeas and lentils. These crops are grown in the Eastern Africa region in varying hectareage, depending on preferences and adaptation to agro-ecological zones. Cowpeas, chick peas, pigeon peas and green grams are grown in lower, drier and warmer areas. Beans and dolichos are grown in the medium rainfall areas of the region while lentils are grown in the cooler regions (Karanja, 2016). Pulses are grown in both mono-cropping and intercropping systems in Kenya. Most common crop combinations in intercropping systems include: maize-beans, maize cowpea, maize-pigeon pea, maize-Soya bean, maize-dolichoslablab, sorghum cowpea, millet-pulses, sugar cane-pulses and rice-pulses (Chui and Nadar 1984; Nadar 1984; Mangale 1989; Matusso et al., 2012; Karanja, 2016). This cropping practice aims to match efficiently crop demands to the available growth resources and labour. The efficient use of available growth resources in a given piece of land and eventually maximizing productivity is the primary advantage of intercropping crops of different height, canopy structure, rooting ability, and nutrient requirements (Matusso et al., 2012). Many studies on intercropping have shown that legumes-cereal intercropping is an important productive and sustainable system due to its resource facilitation and significantly enhancing crop productivity as compared to that of monoculture crops (Matusso et al., 2014). In an effort to improve food security, intercropping cereals with legumes plays an important role by providing a farmer with both carbohydrates and proteins for their dietary needs. Apart from nutritional composition of component crops in an intercropping, it has been also reported that intercropping improves soil fertility through biological nitrogen fixation, increases soil conservation through greater ground cover than sole cropping (Ofori and Stern, 1987; Matussoet al., 2014; Hailu Gebru, 2015; Nyoki and Ndakidemi 2016), and provides better protection against crop pests and diseases than when grown in monoculture (Ofori and Stern, 1987; Matusso et al., 2014; Hailu Gebru, 2015).
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 & Kabete
Despite 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.

Climate change is real and has become an obstacle to sustainable development all over the world. Climate change has positive and negative effects in agriculture depending on the regions of the world. The negative impacts are expected to be more serious in developing countries, particularly those in sub-Saharan Africa such as Kenya. For instance, Kenya has experienced increasing temperatures from 1960’s, together with higher frequency and intensity of extreme weather events such as El Niño and La Niña. Effects of the negative impacts include declining agricultural productivity and loss of crops, livestock, fish and investments in agriculture due to changing temperatures and rainfall and many extreme weather events.

Pulses, or grain legumes in general, are an essential source of supplementary protein to daily diets based on cereals and starchy for a predominantly vegetarian population and those who cannot afford expensive animal protein. Pulses are therefore often regarded as poor man’s meat”. They also provide energy, protein, essential minerals, vitamins and several compounds considered beneficial for good health. Their cultivation enriches soil by adding nitrogen, and improves the physical, chemical and biological soil properties. They are also well suited to diverse environments and fit in various cropping systems owing to their wide adaptability, low input requirements, fast growth, nitrogen fixing and weed smothering ability. Their short growing period and photoperiod sensitivity make them suitable for crop intensification and diversification. Notwithstanding their high production potential, their productivity is generally low as these are cultivated on poor lands, with no or little inputs, and are susceptible to several abiotic and biotic stresses.

Green gram (Vigna radiata L.) also known as Mung bean and in Kiswahili Ndengu is one of the potential food and cash crop pulses that have been observed to perform well in the arid regions of Kenya. The crop is commonly grown in central, south Nyanza, eastern and coastal regions. Green gram is well suited to diverse environments and fit in various cropping systems owing to their wide adaptability, low input requirements, fast growth, nitrogen fixing and weed smothering ability. Sole crop, cereal-bean and root or tuber crop-green gram intercrops are important among the many green gram cropping systems in Kenya and for which the crop‘s rapid maturity and shade tolerance make it particularly suitable.

A significant variation either in the mean state of the climate or its variability, persisting for a period not less than 30 years. Climate change and variability is attributed to both natural and man-made induced causes. In the last 2 decades, causes attributed directly or indirectly to human activity have significantly altered the climate system through the greenhouse gas emissions. It is now evident that the globe is warming and the mean surface temperature has tremendously increased.

The KCEP specific objectives are to support smallholder farmers’ graduate from subsistence to commercial agriculture, enhance post-production management practices and develop market linkages for targeted value chains. Among various other programme roles, KALRO is responsible for the development and, updating of extension materials and guidelines in addition to building the capacity of key stakeholders. Eight training of trainers’ (TOT) workshops covering Nakuru, Kakamega, Nandi, Trans-Nzoia, Bungoma, Machakos, Makueni and Tharaka Nithi counties have been designed to build the capacity of lead farmers, extension agents and service providers who will in turn train the farmers in their respective areas. This curriculum has been developed to guide facilitators who will be involved in the ToTs program planned for the various project areas. The training will be accomplished through lectures, field exercises, practical sessions, role-plays and other adult learning techniques. The curriculum describes the step by step process that will be followed to train on farming as a business (FAB), climate smart agriculture (CSA), soil fertility management, Maize, millet (Pearl and finger) and sorghum and pulses (beans) production and marketing in Kenya.

Most farmers are subsistence oriented and mainly strive to produce food for their households only. However, farmers play a great role, including contributing to food and nutrition security and generating income for their household needs. There is therefore a great need to empower farmers increased participation in embracing farming as a business. A business is viewed as a commercial activity, which operates with the intention of making a profit, by provision of services or commodities to meet needs and wants of customers. This requires changing the mind-set of most farmers from producing only for subsistence use to becoming commercially oriented.

Soil is composed of mineral particles, weathering products of the parent material, and organic matter, (e.g. residues from plants and animals), air and soil water. The solid particles are categorized size into: gravel and stones (>2 mm in diameter), sand (2.0 to 0.02 mm), silt (0.02 to 0.002 mm) and clay (< 0.002 mm). Soil properties are dependent on the relative composition and arrangement of soil particles.l texture is the relative proportions of sand, silt and clay contained in a soil. Soils are described as sands, sandy loams, loams, clay loams, clays depending on their texture.

The scientific name for maize is Zea mays; but for the purpose of this manual it will be referred to as maize. This production manual is a guide on growing maize successfully in different agro-ecological areas of Kenya, in a rain fed system not under irrigation. However, many principles of agronomy are relevant to both irrigated and rainfed farming systems. Maize is a staple food in Kenya, accounting for an average production of 4.4 million tonnes for the period 2010 to 2013 (FAO, 2015). It contributes to about 65% of daily per capita cereal consumption and serves as subsistence and a commercial crop grown on an estimated 1.4 million hectares. Maize production accounts for more than 20% of the total agricultural production and 25% of agricultural employment in the country. It is an important source of carbohydrate, protein, iron, vitamin B, and minerals. Maize products include baked, roasted and boiled fresh maize on the cob, porridge, pastes, beer, starch, oil and livestock feed from by-products of fresh and dry maize grain. This manual outlines important maize-crop agronomy and provides information on the methodology and technology that farmers may be able to utilise to grow maize in Kenya. Climate change, increased human activities, pathogen and vector evolution have increased the spread of invasive pests and diseases in maize farming systems in Kenya. The country has faced severe disease and pest outbreaks that impact on the country’s food security. Heavy attacks of loses of as much as 100% have been reported due to Maize lethal necrosis disease and fall armyworm. The use of Integrated Pest Management (IPM) provides maize farmers with management options to reduce pesticides use in the management of pest and diseases. Precise and prompt pest and disease detection are vital for their prevention or management. After harvesting their crop, farmers in Kenya face challenges of poor grain handling and management, leading to 30% of post-harvest losses, translating to more than US$ 4 billion losses per annum (Hodges et al., 2011). They also market their grain at low price at harvest time forcing households to buy grains for family consumption when prices increase. Post-harvest losses lead to insufficient food supply, even when crop yields and land under cultivation have been increasing. This is partly due to lack of knowledge on appropriate methods of grain storage. This post- 11 harvest management component will support farmers in securing high returns from investments on grain production. This is through adoption of improved on-farm grain handling practices to minimize post-harvest losses and enhanced access to markets offering favourable terms. This manuals’ goal is to reduce post-harvest losses from the current estimated 30% to industry accepted levels of below 5%. This will lead to usage of certified warehouse system by farmers to bulk and sell their produce at a price 30% higher than prevailing farm gate price. systems in Kenya.

The purpose of this training of trainer’s module is to familiarize extension officers, lead farmers and service providers on the millet production practices and empower them knowledge and skills to train farmers’ trainers.. This will enable them to impart knowledge on good agricultural millet production practices to farmers through farmer trainings.Millets are a group of grasses mainly found in the arid and semiarid regions. They produce small seeded grains and are often cultivated as cereals. They include Pearl millet (Pennisetum glaucum), Finger millet (Eleusine coracana), Proso millet (Panicum miliaceum) and Foxtail millet (Setaria italica). The popularity of millet fell for some years due to introduction of maize, wheat and rice, but the current unpredictable rainfall patterns accompanied by frequent maize crop failures have led to renewed interest in the production of indigenous, drought tolerant crops. Popularity of millets is once again on the rise with millers demand being far above the deliveries. Land under millets production in Kenya was 111,271 ha in 2011 with a production of 73,396 tons.

The agriculture sector in Kenya directly contributes 26 per cent of the Gross Domestic Product (GDP) and another 27 per cent of GDP indirectly through linkages with other sectors. However, growth in this sector is constrained by, among other factors, declining soil fertility and deteriorating soil health. Soil management strategies center on: acquisition of appropriate knowledge on soils, their utilization and maintenance of their fertility for sustainable improved crop productivity. This module is intended to familiarize participants on the importance of soil management and recognition that healthy and fertile soils are essential for crop productivity and value chains.Agricultural productivity in Kenya is generally low despite the high demand from the increasing population. Yields of the major staple crops, maize and beans, obtained by farmers are well below the research potential yields and this is attributed to various problems including low soil fertility resource base (low soil organic carbon, nitrogen, phosphorous, potassium and some micro-nutrients) and poor land and water management. Such poor management results in loss of soil nutrients estimated at 21% of nitrogen, 8% phosphorous and 45% Muriate of Potash per year per hectare. Soil fertility management is therefore crucial for farmers to realize potential yields and improve households and national food and nutrition security.

During the year 2006, the Institute implemented several donor supported programmes. These programmes included the Kenya Agricultural Productivity Project (KAPP); the Western Kenya Integrated Ecosystem Project (WKIEMP); USAID-SO7 Project; the Desert Margin Project (DMP); small grants projects such as ecosystems breeding, legumes network project, conservation tillage and others with the support of the Rockefeller Foundation. A number of scientists won competitive grants to supplement the support from mainstream development partners. Several international and CGIAR centres also collaborated with us in the implementation of key research activities. In the same year, the management continued to commercialize its activities through the Agricultural Research Investment Service (ARIS). This greatly improved the generation of funds, internally. Through these projects and the support we received from the Government of Kenya (GoK), we attained most of our targets in our Performance Contract and the Institute was rated 'Very Good' by the Government. During the year under review, we released new varieties of maize and sorghum to the market. Three of the maize varieties were licensed to the East African Seed Company Ltd. (EASEED), Crop Africa and Olerai seed companies. We posted a list of 10 new maize varieties on the KARI website in an effort to create awareness on KARI Maize Research Programme. It is our hope that these efforts will improve farmers' access to seed and the relevant information on suitable varieties for various agroecological zones.
