Savanna regions of Nigeria are deficient in nitrogen and phosphorus, which retard the growth and yield of crops. Therefore, a study was conducted in the wet season of 2006 at the Dry Land Teaching and...
The aim of this study was (i) to evaluate the impact of water deficit and rehydration on nitrogen compounds and abscisic acid of Vigna unguiculata leaves, and (ii) to investigate the hypothesis that a...
An experiment was conducted to test the effect of four plant densities (10, 20, 30 and 40,000 plants ha-1) and four planting patterns (1rowM:1rowC, 1rowM:2rowsC, 2rowsM:2rowsC and 2rowsM:4rowsC) on th...
A field experiment was carried out under rainy season 2006-07, at two locations (Kordofan university farm and Jabal Kordofan ) in Sheikan District, North Kordofan State, Sudan, to investigate the eff...

Farmers in Sistan region experience low crop yields of crops due to low soil fertility. Sole crops and intercrops of maize (Zea mays L.) and cowpea (Vigna unguiculata L.) were studied at eight plantin...
Clavigralla tomentosicollis Stäl, is a notorious pod-sucking bug of cowpea in tropical agro - ecosystems. The improvement of cowpea grain yields by screening of cowpea lines for resistance to pod...
Cowpea is an important grain legume as well as fodder crop, especially in the dry regions of South Africa. The production of this crop has been below average because of low genetic variation and culti...
The grain yield components of eleven cowpea genotypes were studied in 2006 and 2007 at Abeokuta, Nigeria, to understand the sensitivity of the quantitative traits to heterogeneous environments.
Pretreatment of seeds of cowpea (Vigna sinensis Endl.) with indole-3-acetic acid and indole butyric acid had beneficial effects on their germination, dry matter production, flowering and yield. Treat...
At mid-elevation terraces in the southern part of Sumatra Island, Indonesia, cassava is widely cultivated as one of the most important cash crops for farmers. However, the prominent cassava cultivatio...
