Comparative assessment of wheat cultivars and sowing dates under agro-climate of Sheikhupura, Pakistan

Abstract

With the objective to investigate the growth and yield response of three wheat varieties at two different sowing dates, a field study was conducted at Adaptive Research Farm, Sheikhupura, Punjab, Pakistan. The experiment was laid out in a randomized complete block design with split plot arrangement and replicated four times. The cultivars were Inqalab-91, Uqaab-2000 and AS-2002, whereas sowing dates were 24.11.03 and S_­2 = 14.12.03, respectively. The sowing date was randomized in main plot and cultivars were randomized in sub plot. The study revealed that increase in all yield components (fertile tillers, number of spikelets per spike, number of grains per spike and 1000-grain weight) of wheat was observed in November sown crop. The cultivar AS-2002 performed better than the rest of two cultivars. Cultivar AS-2002 with the highest grain yield of 3647 kg ha^-1 and early (November) sowing were considered suitable for farmers under agro ecological conditions of Sheikhupura.
