Abstract: In the present paper, prediction of rice yield under rice-wheat cropping system from 1995-96 to 2003-04 through correlation and regression analysis has been developed. The attributing factors for predicting yield were organic carbon, nitrogen, phosphorus, potassium, pH and EC over nine years data from 1995-96 to 2003-2004. The results revealed that the organic carbon, nitrogen, phosphorus, potassium, had played important roles for describing the inherent variation in yield of rice crop under rice-wheat cropping system.
