Organic Manure Improves Soybean Response to Rhizobia Inoculant and P-Fertilizer in Northern Ghana
Inherently low concentrations of soil nutrients and erratic rainfall pattern in sub-Sahara Africa limit soybean response to rhizobia inoculant and P-fertilizer. The study was conducted to: (i) improve soybean response to rhizobia inoculation and P-fertilizer through the addition of organic manure; (...
