Abstract

A field experiment was conducted at the Research Farm Advanced Centre for Rain-fed Agriculture (ACRA), Rakh-Dhiansar of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu. The experiment was laid out in factorial randomized block design with three replications at during Rabi season of 2018-19 to study the effect of six dates of sowing (31^st October, 15^th November, 30^th November, 15^thDecember, 30^th December and 14^th January) on growth attributes of two wheat varieties (PBW-175 and JAUW-598). The sowing of rain-fed was done at spacing of 20 cm in sandy loam soil. The observations were recorded on plant height, total dry matter accumulation, crop growth rate and relative crop growth rate of wheat crop. Growth of wheat in terms of plant height, dry matter accumulation, crop growth rate and relative growth rate at periodic intervals revealed that at all the growth stages, the growth characters of wheat showed a pronounced improvement with varieties and sowing environments. The data showed significant effects of different sowing time on plant height, total dry matter and crop growth rate while relative crop growth rate found to be non-significant. Among varieties total dry matter found to be significant at 90, 120 DAS and at harvest as well as CGR at 60-90 DAS and 90-120 DAS while plant height and RGR showed to be non-significant at periodic intervals. In addition, the interaction effects were significant in some of observations.
