Influence of soil test based fertilization on soil fertility and productivity of maize

Abstract

In a field experiment conducted during the kharif season of 2015-16 in farmer’s field at Shinganhalli village in Dharwad taluka. The status of soil nutrients, their depletion, build-up and crop productivity on Vertisol was studied. The differences in the values of available N, P2O5 and K2O in soil at 20 cm depth and crop productivity were found to be very marked. The data on yield shows that the application of balanced fertilizer dose of N, P and K as per STCR treatment with farm yard manure @ 10.0 t/ha helped in sustaining the yield of maize at higher. The inclusion of FYM in the treatment schedule maintaining the status of available N, P and K in soil thereby, sustaining the soil health. The under dosing of plant nutrients has caused a depletion in the available nutrients status of soil.
