“…[16] reported that, moderate nitrogen supply increases plant resistance to drought stress, while high or low nitrogen concentrations increase the sensitivity of maize to drought stress. [17] reported that, at silking stage of the maize a positive response in terms of biomass accumulation was observed up to 160 kg N ha -1 and further increase in nitrogen dose from 200 kg to 300 kg N ha -1 , the biomass was decreased when crop irrigation scheduled at 75 % DASM or grown under rainfed situation as compared to irrigation scheduling at 25 % DASM. [18] observed reduction in total shoot dry matter from 8.6 Mg to 8.5 Mg with increasing nitrogen dose from 80 to 160 kg N ha -1 was under drought stress during 1995 no markable change during 1996 and 1997 experiments.…”

A field experiment was conducted at Agro Climate Research Center, Agricultural Research Institute, P.J.T.S Agricultural University, Rajendranagar, Hyderabad, India during rabi 2019-20. The field experiment was laid out in a split plot design with three replications. The treatments comprising of three irrigation scheduling based on (Depletion of Available Soil Moisture) at 60% DASM, 40% DASM and 20% DASM as main plots and three nitrogen levels viz., 90, 180 and 240 kg N ha-1 as sub-plots. The experiment was laid out in split plot design. The results indicated that, among the different treatment combinations, the crop irrigation scheduled at 20 % DASM in conjunction with 240 kg N ha-1 accumulated significantly more dry matter of 34.2 g, 149.2 g, 233.7 g and 284.8 g plant-1, at 6th leaf, silking, dough and physiological maturity stages, respectively. The nitrogen uptake was found to be more when the crop was irrigated at 20 % DASM in conjunction with 240 kg N ha-1 (67.1 g, 231.8 g, 294.7 g and 305.3 g plant-1) at 6th leaf, silking, dough and physiological maturity stages, respectively.

A field experiment was conducted at Agro Climate Research Center, Rajendranagar, Hyderabad, India during post monsoon season of 2019-20 with an objective to optimize the nitrogen dose under varied degrees of water stress environment. The experiment was laid out in split plot design replicated thrice with three irrigation scheduling (60%DASM, 40%DASM and 20%DASM) as main plots and three nitrogen levels (90, 180 and 240 kg of nitrogen ha-1) as sub plots. The results indicated that, at 20% DASM, with increasing nitrogen dose from 90 to180 and further 240 kg ha-1, the plant height and biomass increased significantly. Whereas a significant response in terms of the LAI, number of grains row-1, grain and stover yields and nitrogen uptake by plant was observed up to 180 kg N ha-1.Under deficit soil moisture condition (60% DASM) the maximum plant height (141.5cm), LAI (2.93), biomass (222.3 g plant-1), number of grains row-1 (35.3) test weight (24.1 g), grain yield (4930 kg ha-1), stover yields (7996kg ha-1) and nitrogen uptake by plant was recorded with low nitrogen dose of 90 kg N ha-1 and all these parameters were decreased with increasing nitrogen dose. The concentration of nitrogen in leaf, stem and grain was more under deficit soil moisture condition (60% DASM) and was decreased with reliving plant water stress by scheduling irrigation at 40% DASM and 20% DASM. This investigation evidences the need of nitrogen optimization under varied degree of moisture availability. Under deficit irrigated situation, lower dose of nitrogen is sufficient for optimum yield. Whereas under sufficient water availability, the beneficial effect increased nitrogen levels can be exploited for higher grain yield in maize.
