A field experiment during the year 2015-16 and 2016-17 on two sowing dates (November 23, December 15) and three varieties (cv. HD2733, GW322 and K307) with four replications was conducted at the wheat section, Research Farm, Bihar Agricultural University, Sabour, Bhagalpur to study the performance of rice varieties under different date of sowing . Layer wise soil data was generated and climate data was collected from meteorological observatory, Sabour. Crop management and experimental data was measured from the experimental field. Results revealed that irrespective of variety, timely sown wheat (D1) registered significantly higher grain yield over the two years of study than the wheat crop sown under late conditions (D2). The pooled yield over two years also followed a similar trend. Crop sown on DI recorded a grain yield increase of 15.91 per cent over crop yield sown at D2. The interaction effect between date of sowing and varieties was found to be significant. The treatment combination (D1V1) recorded significantly highest grain yield (47.5 and 48.3 q ha-1) over rest of the treatment combinations and next in order was D1V2 treatment combination with grain yield of 43.7 and 44.4 q ha-1 during both the years of experimentation and pooled of the years. The lowest yield reduction of 13.35 % was recorded in V1 while the maximum yield reduction of 17.30% was recorded in V3 for D2 sowing.
