The East African highland banana (Musa spp. AAA) is an economically important food crop. The crop is affected by a number of diseases and pests. Genetic improvement of the crop is hindered by very low seed set and poor seed germination. The objective of this study was to compare seed set, seed qu...

Seed production from hybridizations involving the East African Highland bananas (Mum spp., AAA group) is low due to high levels of sterility. This is a major impediment for the development of hybrids with disease and pest resistance and superior agronomic traits. The objective of this study was t...

Phosphorus is important for cowpea production in many tropical African soils with inherent low P fertility. Most farmers in Africa, however, do not have access to P fertilizer. Selection of cowpea lines that produce good yield under low soil P or those with high P-use efficiency can be a low inpu...

A total of 137 cycling Zebu cows, each receiving a single dose of prostaglandin PGF 2a were used in an oestrus synchronization programme on three different farms. Of the cows on the three farms, 60.6 and 90.5 percent showed over oestrus and luteolysis, respectively. Pregnancy rate to fixed time i...
