Common bean (Phaseolus vulgaris L.) is an important legume crop grown for household revenue, food and nutrition security in many parts of the world. Common bean is classified into Andean and Middle American gene pools. Most of the beans grown in east and southern Africa countries including Zambia...

Cowpea is an important cultivated grain legume pulse, vegetable and fodder crop of African origin. However, yields have been characteristically low as a result of both abiotic and biotic stresses. Among the abiotic stresses, yield losses due to phosphorus (P) deficiency is an important factor....

Cowpea (Vigna unguiculata L. Walp) is an important legume crop, but drought and soil infertility, especially Phosphorus (P) deficiency are primary constraints for its production. Three studies, a field, greenhouse and hydroponics experiments were carried out at the University of Zambia to...

Yield is a quantitative trait known to be influenced by changes in the environment in which the crop is grown, suggesting the need to evaluate soybean lines in different growing regions to assess their adaptability and stability. The objective of this study were to: (i) Determine yield stability...

Conservation Agriculture has been recommended as a sustainable farming system for many crops in Zambia based on reported improvements in soil infiltration, moisture, soil carbon, microbial activity and reduced bulk density over time. However, the effects in groundnuts such as plant development,...

Agriculture in sub-Saharan African region has depended mainly on rainfall since 1990s and crop production has faced negative impacts of extreme climate events which are believed to be manifestations of long term climate change. In addition, maize (Zea mays L.) productivity has continued to...

Sweetpotato (Ipomea batatas (L.) Lam) is becoming one of the most important tuber crops in Zambia and ranks second in importance from cassava. Orange fleshed varieties are being introduced to reduce vitamin A deficiency. However, the expression of β-carotene content, dry matter content and tuber...

Timely availability of high volumes of good quality planting materials is a challenge especially for crops propagated by vegetative means such as sweetpotato [Ipomoea batatas (L.) Lam.]. Zambian growers rely on volunteer plant sprouts to generate vines. Recently the use of root sprouts has been...

Green houses provide opportunity for year round crop production. Although tomatoes are an option for utilizing greenhouse space, performance of tomato under these conditions has potential limitations which may include root restriction and its attendant impacts such as artificial media effects on...
