Irrigation and Fertilizers Management Practices in Maize (Zea mays L.) and their Residual Effect on Harvest Index and Soil Moisture Studies of Soybean (Glycine max L.)

Experiment was conducted in sequence cropping (Maize - Soybean) with Soybean as residual crop in Kharif at Dharwad on clayey texture in Split split plot with three replications during 2013-14 and 2014-15. Harvest index did not differed significantly with residual effect of irrigation levels. Whereas, residual effect due to fertilizers levels of 250:100:125 kg N:P2O5:K2O ha-1 (2.5:1:1.25) recorded significantly higher harvest index (0.41). Similarly, residual effect of fertilizers application as 33% each (1/3rd) of N, P2O5 and K2O as basal, 33% each of N, P2O5 and K2O at 30 DAS and 33% each of N, P2O5 and K2O at 50 DAS recorded higher harvest index (0.40). Besides, residual effect of interaction due to irrigation and fertilizer management practices did not differed significantly on harvest index.
