The effects of integrated nutrient management (INM) by municipal solid waste manure (MSWM) on wheat yield were studied in rice-wheat and cotton-wheat systems. Each site was used as an independent experimental unit. Two fertilizer doses (conventional and site-specific) were applied in each of three improved techniques: chemical fertilizers, and MSWM plus chemical fertilizers with and without pesticides/ herbicides. The results of three years field trials portrayed the role of INM with MSWM treatment by 9% increased wheat grain and straw yields over unique fertilizer application in cotton-wheat system only. However, INM technique helped in sustaining soil-test P status near to sufficiency levels during 3 years of experimentation in both systems.
