EVALUATING PRODUCTIVITY OF THREE LEGUME SPECIES AND THEIR RESPONSE TO INORGANIC FERTILIZER IN MAKUENI COUNTY, KENYA
(University of Eldoret, 2016)Grain legume production in Makueni County is low mainly due to drought and declining soil fertility. Drought tolerant legumes can be used to mitigate the effects of drought as well as improving soil fertility. The objective ... -
PERFORMANCE OF SELECTED SOYBEAN CULTIVARS AS INFLUENCED BY DIFFERENT RATES OF SYMPAL FERTILIZERS IN BUNGOMA AND KAKAMEGA COUNTIES
(University of Eldoret, 2016)Soybean varieties (Sable, Gazelle and SB19) were developed to improve soybean production in Africa. This study was therefore to investigate the effects of varying the rates of planting fertilizer sympal, and performance ... -
BREEDING FOR COLD TOLERANCE IN RICE (Oryza Sativa L.) FOR THE HIGH ALTITUDE AREAS OF MADAGASCAR
(University of Eldoret, 2016)Low temperature or cold stress is one of the major abiotic stresses limiting rice (Oryza sativa L.) production and productivity in the high altitude of Madagascar; it is affecting an estimated 12.3% of the total rice ... -
THE ASSOCIATION BETWEEN AGRICULTURAL EXTENSION SERVICES AND FOOD SECURITY AMONG SMALL-HOLDER FARMING HOUSEHOLDS IN UASIN GISHU COUNTY, KENYA
(University of Eldoret, 2021)In spite of the importance of the agricultural sector to the economy and as a livelihood to many Kenyans, the sector has been underperforming. In Uasin Gishu County, extension service ineffectiveness has resulted in low ... -
CHARACTERIZATION OF GAMMA IRRADIATED TEA ACCESSIONS USING BIOCHEMICAL AND MORPHOLOGICAL MARKERS
(University of Eldoret, 2021)Mutation breeding as an alternative method of crop improvement has widely been used to broaden the genetic variability of most cultivated plants except tea. A study was carried out to determine the effect of different gamma ... -
