Explanation:

Efficient utilization of P from press mud cake (PMC) in the rice-wheat rotation is critical in reducing the costs of fertilizer P and improving soil fertility. The objective of this study was to determine the effects of variable rates of PMC and fertilizer P on yield and soil fertility under rice-wheat rotation on a silt loam (Aquic Ustorthent) soil in the flood plains.
