Effect of sowing environments and N-levels and their interaction on growth and yield of wheat varieties under irrigated conditions of lower hills of J&K UT

Experiments were conducted at Agromet Research Farm, SKUAST-J, Chatha, J&K UT in rabi 2015-16 and 2016-17, to evaluate the effect of sowing environments and N-levels on growth parameters, their interactions and yield of wheat (Triticum aestivum L.) varieties. Three wheat varieties (HD 2967, RSP 561 and WH 1105), 3 sowing environments (25^th October, 14^th November and 4^th December) and 3 N-levels (100, 125 and 150 kg/ha) were laid out in split plot design with 3 replications. The results revealed that variety WH 1105 observed significantly superior growth parameters viz. plant height, no. of tillers/m row length, crop growth rate, relative growth rate and grain and straw yields of wheat as compared to the varieties HD 2967 and RSP 561. Variety RSP 561 recorded lowest values of growth parameters and yield. Among the sowing environments, the early sown (25^th October) wheat crop envisages significantly higher values of growth parameters and grain yield. Whereas, statistically notable values of the same recorded in higher dose of nitrogen (150 kg/ha), but the values were at par with 125 kg N/ha.
