“…practices, the upper leaf blades are starved of nitrate during the crucial reproductive phase According to the prevalent agronomic practices and there is scope for enhancing their nitrate of wheat cultivation, nitrogen is applied in two assimilation potential by application of nitrogen splits: half of the total dose is given at sowing in more than two splits (POKHRIYAL et al 1980, and half at the time of tillering (approximately KUMAR et al 1981, ABROL 1990).…”

A field experiment was conducted with different nitrogen regimes to assess the growth and yield performance of wheat genotypes which differ in nitrate assimilation potential. Genotypic differences in biomass accumulation were observed at different growth stages. The nitrogen treatment had little effect on biomass accumulation at early stages of growth, while at later stages of growth there was enhanced biomass accumulation when N was applied in more than two splits. On an average, genotypes with high nitrate reductase activity (the ‘HNR’ genotypes) accumulated 14.2 % more biomass than the genotypes with low nitrate reductase activity (‘LNR’ genotypes) when an extra dose (40 kg N ha−1) of nitrogen was given at the time of anthesis. The application of nitrogen in more than two splits increased grain yield of both ‘HNR’ and ‘LNR’ genotypes mainly by increasing grain weight per ear. The application of an extra dose of nitrogen (40 kg N ha−1) at the time of anthesis increased grain yield of ‘HNR’ genotypes by 38.5 % as compared to ‘LNR’ genotypes.

“…However, N content of MNE cultivars did not increase significantly with the supply of 25 mM N over T2 (10 mM N). Ontogenetically, the pattern of NR activity corresponds to nitrate content, to which it is significantly correlated (Pokhriyal et al 1980;Kumar et al 1981). In the present Fig.…”

This study suggests that the HATS, high NR, and glutamine synthetase activity and the soluble protein content distribution have a key role in N efficiency of rice genotypes. These parameters may be considered in breeding and genetic engineering programs for improving the NUE of rice, which might be helpful in reducing the fertilizer loss, hence decreasing environmental degradation and improving crop productivity through improvement of nitrogen utilization efficiency in rice.
