Effect of different sowing dates on growth and yield of wheat (Triticum aestivum L.) varieties in district Jhang, Pakistan.

Abstract

In a field experiment at Faisalabad, Pakistan conducted during winter 2005-06, the effect of three sowing dates December 1, 15 and 30 on three wheat cultivars Inqlab-91, AS-2002 and Bhakkar-2002 was studied. Sowing dates and varieties both significantly affected the number of fertile tillers m, plant height, number of spikelets per spike, 1000-grain weight and grain yield. In case of sowing dates significantly maximum grain yield (4289.54 kg ha) was obtained when crop was sown on 1 December against the minimum grain yield (2109.50 kg ha ) in case of late sowing i.e. 30 December. Among of varieties Inqlab-91 gave significantly maximum yield (3550.44 kg ha) while minimum yield (2932.59 kg ha) was obtained by AS-2002.
