Two peak periods of nitrogen efficiencyi.e., first at tillering and second at ear-initiation stage were observed.
Maximum uptake of nitrogen and protein content was noted in treatment where nitrogen at 56 kg N was applied with 44.8 kg P2O5 per hectare.
The rate of nitrogen uptake from seedling to tillering was about 45 per cent; from jointing to ear initiation 25 per cent, and 30 per cent upto grain-formation stages in wheat plant's life cycle.
Best recovery of nitrogen of 53 per cent was noted in treatment where 56 kg N + 44.8 kg P2O5 per hectare was applied.
