Item Agricultural Research Programme 1965(ministry of Agriculture, 1965) Ministry of Agriculture; Peeler, C. H.I forward herewith a copy of the Kenya Government, Research Division, Agricultural Research Programme f or 1965.Item Derris Agronomy: An Annotated Bibliography and a Critical Review(1944) Moreau, R.E.; East African Agricultural Research Institute, AmaniThe published data, with the addition of some unpublished for East Africa, are reviewed under the following heads: selection and breeding (with a table showing the toxic contents attained); variability; climate and derris; shade: the age for harvesting; root character and toxicity; the effect of manuring: yields and spacing: propagation by cuttings: staking; pests and diseases: histology and bio- chemistry of rotenone in derris plants. On the whole results and opinions are remarkably inconclusive and conflicting. There is a wide field for carefully planned experimentation. The Tanga Province of Tanganyika Terri- tory is at present practically the only producer of high-grade derris root in the British Empire. Production and prospects elsewhere are mentioned. The Tanganyika derris industry is based on clonal material of D. elliptica Changi type, with satisfactory toxic content, but not nearly so good as the more recent selections in Java and Malaya. Commercial production in Tanganyika is all in climates cooler or drier, or both, than thought desirable in the Far East. Maturation is much slower than elsewhere, so that harvesting is not recommended before 30 months, compared with 18-24 elsewhere. Excellent yields have been obtained on soils, as well as in climates, that would, on experience elsewhere, be classed as unfavourable.Item KARI Kitale Quarterly Progress Report Oct to Dec 2005(Kenya Agricultural Research Institute, 2008) Kenya Agricultural Research Institute; Nkonge, C.
