An experiment was conducted to investigate the insecticidal activities of seven plant materials (1-5g/100g cowpea seeds) namely: citrus peel powder (CPP), Acacia leaf powder (ALP), Occimum leaf powder (OLP), mahogany bark powder (MBP), hot pepper powder (HPP), ginger powder (GP) and mahogany wood ash (MWA) and a synthetic insecticide, pirimiphos-methyl dust (PMD) (0.1-0.5g/100g cowpea seeds) as...

BACKGROUND The present study investigated the effect of seven Bacillus-species plant-growth-promoting rhizobacteria (PGPR) seed treatments on the induction of disease resistance in cowpea against mosaic disease caused by the blackeye cowpea mosaic strain of bean common mosaic virus (BCMV). RESULTS Initially, although all PGPR strains recorded significant enhancement of seed germination and se...

Cowpea [Vigna unguiculata (L.) Walp.] is an important warm-season legume grown primarily in the semi-arid tropics. The majority of cowpea is grown by subsistence farmers in west and central sub-Saharan Africa, where its grain and stover are highly valued for food and forage. Despite its economic and social importance in developing parts of the world, cowpea has received relatively little attent...

Intercropping is regarded as an important agricultural practice to improve crop production and environmental quality in the regions with intensive agricultural production, e.g., northern China. To optimize agronomic advantage of maize (Zea mays L.) and soybean (Glycine max L.) intercropping system compared to monoculture of maize, two sequential experiments were conducted. Experiment 1 was to s...

Sweet sorghum is a popular grain crop grown in water stress prone areas in the world. Its sole stand leaves ample resources untapped. This study evaluated the feasibility of intercropping sweet sorghum using eight intercropping patterns composed of 2 x 2 x 2 factorial combinations of two legumes (viz. mung bean and soybean), two row patterns [viz. alternate single row (ASR) and double row (ADR)...

Intercropping is considered for increasing and stability of yield per unit. In order to study the effects of different intercropping arrangements on sorghum and mungbean yield and to find the land use advantage in the intercropping system, an experiment was carried out based on a randomized complete block design with seven treatments and three replications at the Research Farm, Faculty of Agric...
