Over the years, a scarcity of information on nutrient gains or losses has led to overemphasis being placed on crop yields and economic income as the direct benefits from fertilizer micro-dosing technology. There is increasing concern about the sustainability of this technology in smallholder Sahe...
Limited availability of soil organic amendments and unpredictable rainfall, decrease crop yields drastically in the Sahel. There is, therefore, a need to develop an improved technology for conserving soil moisture and enhancing crop yields in the Sahelian semi-arid environment. A 2-year field exp...
Inadequate nutrient supply and insufficient rainfall are the most important limiting factors for crop production in the Sahelian agro-ecological zones. Targeted technology application may help to improve the efficient use of limited nutrient and water resources. The objective of this study was to...
Recent studies have reported the benefits of fertilizer microdosing in increasing crop yields in low input cropping systems. Little information is however available on the mechanisms underlying this effect. The objective of this study was therefore to explore the root-based mechanisms governing t...
During recent decennia, new commercial products have appeared on the market as alternatives to common fertilizers. While some of these products are based on well-established technologies, such as rhizobium inoculation, others have not been subjected to scientific scrutiny. During 3 years, we eval...
Field experiments were conducted in 2005 and 2006 rainy season at the Institute for Agricultural Research farm, Samaru, Nigeria, to test the response of four cowpea [Vigna unguiculata (L) Walp] varieties to residual effect of four rates of sheep manure (FYM) (0, 5, 10 and 15 t/ha) applied the pre...
Drought stress causes significant yield reduction in maize Zea mays L. grown in sub-Saharan Africa (SSA. An understanding of the inheritance of drought tolerance would be useful in developing drought tolerant hybrids. The objectives of this study were to determine (i) the effects of the level of ...
La sdcheresse est un stress qui cause une r6duction significative derendement chez le mdis Zeo moys L) en Afrique sub-Saharienne(AS9. La compr6hension du mode de transmission de la tol6rancei la sdcheresse serait utile pour la cr6ation d'hybrides tolfrants d las6cheresse. Les obiectifs de cette 6...
To investigate the relationships of slaughter and carcass data with carcass composition, forty-eight (4-6 months old) entire male Sudan desert goats were purchased and moved to Kuku livestock fattening center. The animals were rested, ear-tagged, dewormed, supplemented with cotton seed cake and w...
Objective: Drought and low soil nitrogen(low N) are the most important environmental constraints contributing to yield in stability of maize (Zea mays L.). Evaluation of maize genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield pote...
