Hedgerow Intercropping Maize or Cowpea/Senna for Drymatter Production in Semi-Arid Eastern Kenya
(Department of Meteorology, University of NairobiDepartment of Agricultural Engineering, University of Nairobi,Department of Plant Science and Crop Protection, University of Nairobi, 2011)In a long term study photosynthetically active radiation was monitored for three rainy seasons to measure the effects of hedgerow intercropping in rotation with maize and cowpea in a senna/siamea and panicumlgrass strip ... -
Farmers’ participatory selection for early bulking cassava genotypes in semi-arid Eastern Kenya
(Department of plant Science and crop protection, University of Nairobi, 2011)Cassava is an important food security crop in semi-arid, Eastern Kenya, but production is constrained by planting late bulking landraces. Therefore, farmer participatory variety selection was initiated with the aim of ... -
Introgression of stay-green trait into a Kenyan farmer prefered sorghum variety
(Department of plant Science and crop protection, University of Nairobi, 2010)Backcross breeding enables breeders to transfer a desired trait from a Genetic Improvement of Kenyan sorghum variety for drought resistance donor parent, into the favoured genetic background of a recurrent parent. This ... -
Combining the yield ability and secondary traits of selected cassava genotypes in the semi-arid areas of Eastern Kenya
(Department of plant Science and crop protection, University of Nairobi, 2010-07)Despite the importance of cassava for food security in semi-arid areas of Kenya, there is a lack of information regarding gene action determining yield of local varieties. Therefore the objective of this study was to ... -
