Growth, Yield and Yield Components Response of Local Sorghum Varieties to Nitrogenous Fertilizer Rates in Northern Ghana

Abstract

The economic importance of Sorghum (sorghum bicolor L. Moench) to rural households and household food security in northern Ghana, remains a key reason for the continues cultivation of the crop, though average yield (700 kg/ha) is below that of maize and rice. The low yield, however, implies that sorghum could contribute more to food supplies than at present, especially in resource-constrained regions and people in greatest need. The crop has been referred to as one with vast untapped potential [1,2].
