Gs. Bhatnagar et al., LONG-TERM EFFECT OF CONTINUOUS MAIZE (ZEA-MAYS) WHEAT (TRITICUM-AESTIVUM) CROPPING SYSTEM AND MANURING ON SOIL FERTILITY AND STABILITY IN CROP YIELD, Indian Journal of Agricultural Sciences, 64(12), 1994, pp. 821-823
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.
