The aim of this study was to evaluate the effect on carcass characteristics of Cobb 500 broiler chickens of supplementing cowpea meal with Methionine and Lysine only as well as supplementing the cowpea with Methionine, Lysine and Threonine. A total number of 100 day old chicks were used. An...

Under increased population pressures, extensive methods of arable cultivation give way to intensive ones. The whole agricultural policy area then becomes central in influencing and further determining production trends and, consequently, the farming system that evolves. In most developing...

Bambara groundnut [Voandzeia subterranea (L)] Thouars is a grain legume crop grown by peasant farmers in Zambia. The crop has been found to be useful in many farming systems as it contributes to human nutrition and soil amendments. Unfortunately, its full potential has not been fully exploited in...

The grain yield of wheat in Lesotho is low because of poor soil fertility, and the wheat is regarded by the millers to be of poor quality and therefore of less value. A field study was therefore conducted at three sites in Lesotho( Maseru, Leribe and Mafeteng) to evaluate the influence of...

Differences were found in lodging and mechanical strength tests among pearl millets, pearl millet x Napier grass (PMxNG) lines, test crosses and sorghum. In 1987 field lodging ranged from 0 to 98%. Test crosses with PMxNG lines lodged worse on average than the millets or sorghum, but they were...

The seed yield of sesame in Zimbabwe is low compared to other countries, yet the crop is gaining in economic significance. A trial was therefore conducted at Gwebi, Zimbabwe, to evaluate the effects of plant population and fertilizer nitrogen rate on the yield and yield components of sesame...

Maize is the main staple food crop in the Southern Africa Development Community (SADC), which includes Zimbabwe and its productivity increases when improved varieties are planted. Development of such technologies is mainly by public and private breeding programs, which in most cases do this in...

Soybean (Glycine max (L.) Merr.) is an important crop in Zambia but many foliar diseases pose a serious threat to its successful production in the country. During the last three years frogeye leaf spot disease caused by Cercospora sojina Hara has become the most prevalent disease in most parts of...

Maize is an important staple and cash crop in Zambia. Abiotic and biotic stress conditions, particularly low soil fertility (low nitrogen) and grey leaf spot(Cercospora zeae- maydis), reduce maize yields. Most varieties developed by the Zambian National Maize Programme have neither resistance to...
