Item Assessment and Monitoring Nutrient Flows and Stocks to Determine Appropriate Integrated Nutrient Management Strategies: Technical report on the study approach and preliminary results of NUTSAL project, 1998/99.(Kenya Agricultural Research Institute, 2000) Gachimbi, L. N.; Ikombo, B. M.; Itabari, J. K.; Nandwa, S. M.; Nguluu, S.M.; Kinama, J. M.; Thuranira, E. G.; Karuku, A. Μ.; de Jager, A.; Keulen, H. V.; Kenya Agricultural Research InstituteThe National Soil Plant Nutritional (NSFPN) Research Programme has the mandate to contribute towards increased agricultural production in the high, medium and low rainfall areas in Kenya. This constitutes 44.6 million hectares of land of which only about 8.6 million ha is high to medium potential. The rest is either semi-arid or arid. The programme aims at increased crop production through integrated nutrient management approached under different cropping systems and appropriate tillage practices. Improved production of crops and livestock in a sustainable manner is a key to agricultural development in arid and semi-arid lands.Item The Role of esicular-Arbuscular Mycorrhiza .. in the Phosp or us Nutrition of Cowpea (Vig a unguiculata (L.) Walp.)(1990) Ikombo, B. M.; Edwards,D. G.; Asher, C. J.Item The Role of Vesicular-Arbuscular Mycorrhizas (VAM) In the Phosphorus Nutrition of Cowpea (Vigna Unguiculata (L.) Walp.)(1991) Ikombo, B. M.; Edwards, D. G.; Asher, C. J.An experiment was conducted to establish the role of VAM in the phosphorus nutrition and early growth of cowpea (Vigna unguiculata (L) Walp.) cv. Vita 4 in a podzolic soil (Haplustult). The experiment involved four treatments: (1) plants grown in unsterilized soil adequately supplied with phosphorus (240 kg P ha-I ), (2) plants grown in unsterilized soil with low phosphorus (10 kg P ha-1), (3) and (4) plants grown in methyl bromide sterilized soil with low phosphorus (10 kg P ha-1). Plants in treatments (1), (2) and (3) were inoculated with Bradyrhizobium. A series of harvests was taken from 14 to 42 days after sowing; 15 harvests at two-day intervals from treatment (2) and 5 harvests at 7-day intervals from the other treatments.
