Effect of rice straw application on lowland rice cultivation in the Guinea savanna zone, Ghana

摘要

Low inherent soil fertility has been identified as a major cause for low rice yield (Abe et al, 2010; Buri et al, 2004; Issaka et al., 2009; Senayah, et al., 2008). The problem is compounded because farmers are unable to purchase fertilizer (relatively high cost) and rely mostly on natural soil fertility, which is low and declining.
