Intercropping and its application to banana production in East Africa: A review
Bananas are very important in Kenya for domestic consumption and export. They are extensively grown where they are mainly intercropped with short term crops. There has been an increase in the grower interest in using intercropping-growing two or more crops simultaneously on the same land in the development of new cropping systems for their land. Intercropping could reduce management inputs and result in...

Genetic yield stability in some sunflower (Helianthus annuus L) hybrids under different environmental conditions of Sudan
Nineteen locally developed sunflower (Helianthus annuus L.) hybrids and an introduced one (Hysun 33) were evaluated at two irrigated locations, New Halfa and Rahad for two consecutive seasons (2003/04 and 2004/05) in order to estimate stability of performance for seed yield per ha (t). A randomized complete block design with four replicates was applied at each location. Data on seed yield was collected....

Resistance in Kenyan bread wheat to recent eastern African isolate of stem rust, Puccinia graminis f. sp. tritici, Ug99
Stem or black rust, caused by Puccinia graminis, has historically caused severe losses to wheat (Triticum aestivum) production worldwide. The causal race, commonly known as Ug99 and designated as TTKS based on the North American nomenclature, carries virulence for several genes commonly present in wheat germplasm. All Kenyan germplasm are known to be susceptible or partially susceptible to Ug99 although no proper...
