Effect of different dates of sowing on yield and yield attributes of wheat (<em>Triticum aestivum </em>L.) cultivars

Abstract

A field experiment was carried out at Agromet. Research Farm of Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during Rabi season of 2016-17 to study the effect of different date of sowing on growth and yield of wheat (Triticum aestivum L.) cultivars. The experiment comprised of 9 treatment combinations and tested in Randomized block design (RBD) with four replications. Experiment consisted of two factors, viz. dates of sowing and cultivars. Three wheat varieties, viz. Malviya-234, PBW-343 and NW-1012 were sown under three dates i.e. 20 November, 30 November and 10 December. 20 November has suitable date of sowing for high yield of wheat. PBW-343 cultivar was found most suitable for obtaining higher yield of wheat. Variety PBW-343 produced significantly higher grain and straw yield (39.45 and 55.50q ha-1, respectively). Regarding the time of sowing, highest grainand straw yield (39.60 and 54.77q ha-1, respectively) was recorded in the crop, sown on 20 November.
