Abstract
A long-term field experiment was conducted since rainy and winter seas ons of 1978-79 to 1987-88 on a clay-loam soil, to evaluate the effect of continuous maize (Zea mays L.)-wheat (Triticum aestivum L. emend Fi ori & Paol.) cropping system on soil fertility and stability in crop y ield Application of nitrogen @ 120 kg/ha and phosphorus @.17.5 kg/ha t o each crop significantly increased the grain yield of maize (2025 and 1803 kg/ha) and wheat (3112 and 2914 kg/ha) respectively. The fertili zer application resulted in building up the organic C,P and K status o f the soil.
