Effect of lime, organic and inorganic nutrients on wheat (Triticum aestivum) soybean (Glycine max) cropping system in acidic red soils

A field experiment was carried out during 1988-89, 1989-90 and 1990-92 to s tudy the direct effect of lime, organic and inorgnic nutrients on wheat (Tr iticum aestivum L. emend. Fiori & Paol.) and its carry-over effect on soybe an [Glycine max (L.) Merr.]. Lime (1.25 tonnes/ha), FYM (4 tonnes/ha) and b oron (10 kg/ha) in combination with 60 kg N + 30 kg P2O5 + 20 kg K2O/ha res ulted in the highest yield of wheat (29.3 q/ha). A significant residual eff ect was also observed for soybean (23.4 q/ha) with application of 30 kg N 60 kg P2O5 + 30 kg K2O/ha. The direct and the carry-over effects of lime a nd organic manure along with inorganic nutrients application significantly increased the uptake of N, P and K by both the crops in the cropping system .
