Response of Cowpea (Vigna unguiculata L.) Genotypes to Wicth Weed (Alectra vogelii Benth) Infection
A greenhouse pot experiment was conducted at the University of Zimbabwe to screen six cowpea varieties for resistance to Alectra vogelii infection. Emergence of A. vogelii was first detected 55 days… Expand
Variability in condensed tannins and bitterness in spider plant genotypes
Spider plant ( Cleome gynandra L .) contributes considerably to the nutrition and medicines of communities in southern Africa. However, its utilisation is limited by its bitterness caused by… Expand
Potential for quality protein maize for reducing proteinenergy undernutrition in maize dependent Sub-Saharan African countries: A review
Most cereal crops, including maize ( Zea mays L .), are deficient in essential amino acids, such as lysine and tryptophan; hence they are poor in protein quality. A mutant maize with elevated levels… Expand
Weed community responses to rotations with cover crops in maize-based conservation agriculture systems of Zimbabwe
Abstract Weed management is a challenge to resource constrained smallholder agricultural production in sub Saharan Africa due to insufficient and inadequate management strategies. When weeds are… Expand
Participatory Development of Tillage/Weed Management Practices for Maize Farmers in Semi- arid Zimbabwe: Who benefits?
Farmers, research and extension have been developing and testing moisture conserving tillage/weeding practices for a maize-based cropping system in semi-arid Zimbabwe which is characterised by labour… Expand
Effect of herbicide application on weed flora under conservation agriculture in Zimbabwe
Increased challenges of weed control in the smallholder farming sector of southern Africa have often resulted in small yields. The objective of this study was to evaluate the effects of different… Expand
Grafting and 2.4-dichlorophenoxyacetic acid induced flowering in non-flowering sweetpotato in sub-tropics
Abstract In sub-tropics, most sweetpotato genotypes do not flower at all. The aim of this study was to develop methods of inducing flowering based on the application of 2.4-dichlorophenoxyacetic acid… Expand
Quantification of sorgoleone in sorghum accessions from eight southern African countries
Allelopathic effects of sorghum (Sorghum bicolor (L.) Moench) can ease weed pressure and improve grain yields if cultivars capable of producing high levels of natural chemicals effective in… Expand
Allelopathic Effects of Aqueous Extracts of Sorghum (Sorghum bicolor L. Moench) on the Early Seedling Growth of Sesame (Sesamum indicum L.) Varieties and Selected Weeds
Sesame (Sesamum indicum L.) production is lucrative to resource poor farmers in marginalised areas of Zimbabwe, although most farmers have reportedly been failing to derive maximum economic benefits… Expand
