Item Climatic Variability and Agricultural Production in Central and Eastern Kenya: Implications for Policy(1995) Down i n g, T. E •; Potter, H.L.; Mungai, D.N.; Muturi, H.R.This paper presents the conclusions from the previous papers of the Kenya Case Study for the Assessment of Climatic Impacts on Agriculture, Volume 2: Semi-Arid Regions. Previous strategies for developing the semi-arid areas of Kenya are outlined. Recommendations for future policies to reduce vulnerability to and the impacts of climatic variability are suggested.Item Climatic Variability and Livestock Production in an Area of Eastern Kenya(1985) Potter, H.L.; Kenya Agricultural Research InstituteThe implications of climatic variability for livestock enterprises in three agroclimatic zones (III, IV and V) of eastern Kenya are discussed, based upon the situation of the typical smallholder. The paper is part of the Kenya Case Study for the Assessment of Climatic Impacts on Agriculture in the Semi-Arid Regions.Item Seasonal Variation in Productivity and Nutritive Value of Napier Grass at Muguga, Kenya(1994) Anindo, D.O.; Potter, H.L.; National Agricultural Research CentreThere has been a renewed interest in the use of Napier grass (Pennisetum purpureum) forage for ruminant feed in East Africa. Studies conducted earlier tended to concentrate on the agronomy of the grass. Dry matter yields, height and frequency of harvesting and responses to various fertilizer treatments have been extensively elucidated in East Mrica and elsewhere (Caro-Costa and VicenteChandler, 1961; Mwakha, 1972; Mugerwa and Ogwang, 1976; Goldson, 1977; Karanja, 1981).Item Seasonal Variation in Productivity and Nutritive Value of-Napier Grass at Muguga, Kenya(1994) Anindo, D.O.; Potter, H.L.Seasonal variation in productivity and nutritive value of Napier grass (Penniselum purpureum) was assessed in a high potential area of Kenya to determine the factors affecting the seasonality of the growth. Fifty-five plots of 0.3 ha each were established on a single fie1d selected for uniformity of soil and topography. Fertilizer was supplied at the rate of 6.3 and 4.5 kg/ha of N and P respectively, at each cycle of cutting. Commencing approximately 6 months after planting, one plot was harvested each day in rotation so that an 8-week cutting cycle was established and maintained throughout the trial. The data were obtained from samples taken twice a week, and included dry matter (DM) yield, crude protein (CP), neutral detergent fibre (NDF) and acid detergent lignin (ADL). Dry matter digestibility of the Napier grass was determined in vivo using Boran steers during a wet and a dry season growth periods respectively.
