OPTIMIZED INORGANIC FERTILIZER APPLICATION ON SORGHUM YIELD AND NITROGEN USE EFFICIENCIES IN THE NIGERIAN SAVANNA
ABSTRACT Sorghum (sorghum bicolor (L.) Moench) is an important staple food grain that is grown among smallholder farmers. The yield is low due to inherent low soil fertility because resource poor farmers apply little to no fertilizer to their land due to economic and social factors. The objective of the study was to provide recommendations for optimizing yield and profit from fertilizer use for financially constrained and smallholder sorghum ...
