Abstract:

Cowpea (Vigna unguiculata) is an important indigenous multi-purpose crop grown in arid and semiarid areas of Sub-Saharan Africa (SSA). The cowpea has nutritional and economic value, especially for smallholder farmers in dry lands. However, poor farming practices have declined cowpea productivity over the years. Low soil nutrient replenishment exacerbates the situation, leading to low soil fertility. Uptake of regenerative agriculture (RA) technologies is critical to building more resilient ecosystems that improve soil fertility and agricultural productivity while mitigating climate change effe

Cowpea is one of the most important vegetable that ranks third among pulses and top five leafy vegetables consumed in Sub Saharan Africa. In Kenya cowpea contributes to cheap supply of nutritious food, revenue and food security. Despite its importance, cowpea production levels are a fraction of the potential due to low technical efficiency of production which affects the revenue levels and food security of the smallholder farmers.

Abstract Cowpea [Vigna unguiculata (L) Walp.] is an important staple legume in the diet of many households in sub-Saharan Africa. Its production, however, is negatively impacted by many insect pests including bean pod borer, Maruca vitrata F., which can cause 20–80% yield loss. Several genetically engineered cowpea events that contain a cry1Ab gene from Bacillus thuringiensis (Bt) for resistance against M. vitrata were evaluated in Nigeria, Burkina Faso, and Ghana (West Africa), where cowpea is commonly grown. As part of the regulatory safety package, these efficacy data were developed and eva

Cowpea (Vigna unguiculata (L.) Walp.) is an important legume crop that is recognized for its adaptability to diverse climates and nutritional value. In Jammu and Kashmir, however, its genetic diversity is limited, hindering full yield potential. This study aimed to characterize 72 cowpea genotypes from various regions of Kashmir through Distinctness, Uniformity, and Stability (DUS) characterization. Twenty-four agro-morphological traits were assessed following the guidelines of the Protection of Plant Varieties and Farmers' Rights Authority (PPV&FRA). Key traits, such as stem color, flower
