NODULATION OF COWPEA

Abstract Cowpea (Vigna unguiculata [L]Walp) can obtain nitrogen from the atmosphere by the process of biological nitrogen fixation when associated with specific and effective rhizobia. The purpose of this study was to evaluate the effect of different rates of phosphate fertilizer on nodulation and dry matter yield of cowpea. A Randomized Complete Block Design with four treatments and three replications was used. The trial was conducted on the field. The treatments consisted of different rate...

INFLUENCE OF NITROGEN AND PHOSPHORUS ON NODULATION AND YIELD OF SOYBEAN

AbstractGrain legumes are getting popular all over the world, either because of their high protein or oil content and potential to improve soil fertility. A field study was undertaken with two grain legumes; Soybean and Cowpea, that are economically important in the semi-arid region at the Irrigation Research Farm of Institute for Agricultural Research, Kadawa, Kano in the Sudan Savanna to gain an understanding of fertilizer application rates on nodulation and yields of Soybean (TGx 1904-6F) ...

ASSESSMENT OF SOIL CHEMICAL DEGRADATION UNDER KOLANUT PRODUCTION IN IMOTA LAGOS STATE

ABSTRACTOne of the most serious problems currently affecting agricultural production in developing countries especially Nigeria is land degradation. The adverse effect of land degradation on soil production, soil health and food security is an important current global issue. Hence, this study assessed the chemical degradation of soils under kolanut production with the view of optimizing its production through appropriate management practices that is environmentally friendly and sustainable. S...
