Kang, B.T.Fox, R.L.[Influence of soil fertility on the protein and sulphur contents on grain legumes]Influence of soil fertility on the protein and sulphur contents on grain legumes

A researcher-managed on-farm experiment was conducted on a soil with low 1.90 mg/kg available phosphorus (P) to evaluate nutrient carryover from soybean grown under different P management options and productivity of maize grown in rotation. Promiscuously nodulating 110-day maturing soybean variet...

Promiscuous soybean lines have been bred on the basis that they would nodulate freely without artificial inoculation. However, our recent studies have demonstrated that the indigenous rhizobia are not able to meet their full nitrogen (N) requirement. Rhizobia inoculation might be necessary. We ex...

The supply response of the smallholder soybean growers was investigation using a sample of 307 farmers randomly-selected from Jive villages in Kaduna and Kano States of Nigeria. Different multivariate functional forms were experimented but the power Junction was chosen because of its obvious uniq...

Seed viability and emergence is one of the most important problems affecting soybean production in West Africa. Results from the multi-location yield trials indicated that introduced cultivars such as Bossier, Jupiter and Improved Pelican showed excellent adaptation and high yields provided seedl...
