Abstract:

A field experiment was conducted during the rabi season of 2016-17at Research farm of Bihar Agricultural College, Sabour, to evaluate the effect of tillage, sowing time and irrigation levels on nutrient uptake and yield of maize (Zea mays L.).The experiment comprised of two tillage methods viz. conventional tillage (CT) and zero tillage (ZT) in main plot, two sowing dates- 30th October and 10th November as sub-plot and three irrigation levels (I2 - 2 irrigations at six-leaf stage and tasseling, I4 - 4 irrigations at four-leaf stage, ten leaf stage, tasseling and milking and I6 - 6 irrigations at four-leaf stage, eight leaf stage, ten leaf stage, tasseling, milking and dough stage) as sub-sub plot treatment. The results indicated that the nutrient dynamics and productivity of rabi maize is significantly influenced by management practices. The higher nutrient content was recorded in CT maize stover and ZT maize grain and with 4 irrigations. However, maximum nutrient uptake and grain yield (11.1 t ha-1) was recorded in ZT system with six irrigation. Delay in sowing of rabi maize reduced the grain yield considerably at a rate of 121 kg/ha/day. With increasing resource as well as crop management constraints, adoption of ZT along with residue retention and optimum water use has the potential of improving the nutrient uptake, nutrient use efficiency and crop productivity.
