ABSTRACT
Rains are expected to decrease and temperature has to rise for wheat growth in Pakistan. Wheat crop is planted on more than 52% area as rainfed crop in the providence Khyber Pakhtunkhuwa (KP). The study, therefore, aims to plant wheat in season from early to late i.e. November 15 to December 25 with about 10 days intervals. Field experiment was conducted at Agronomy Research Farm, the University of Agriculture Peshawar in winter season 2015-16. Experiment was in a randomized complete block design, in split plots having three replications. Sowing dates were assigned to main plots and wheat varieties (i.e. Shahkar-2013, Atta-Habib-2010, Pakhtunkhwa-2015, Hashim, Dharabi, Chakwal-50, Pakistan-2013 and Ghanemat-2015) to sub plots. Results revealed that sowing dates and varieties significantly affected yield and yield related traits. Sowing made on November 25 showed higher yield than the expected early sown on November 15 or late sown thereafter on December 5 in season in the region. Overall delay in sowing date i.e. from December 5 onwards resulted in sever losses in biomass and grain yield (GY). On averages of varieties, a decrease in biological- and grain yield was estimated 261 and 89 kg ha-1, reapectively, per day in wheat in season for Peshawar when sowing was postponed from December 5. Early planting delayed days to anthesis and maturity, which otherwise extended grain development phase of the crop. Among varieties, Ghanemat-2015 showed better grain yield for a relatively longer duration i.e. December 5-15 over the others varieties. Atta-Habib also performed relatively better for sowing made on November 25 and Chakwal-50 on November 15. Overall GY reduced when wheat sowing postpones from December 5 in the season. Grains protein was observed high for sowing made on November 15-25 for wheat varieties Dharabi, Shahkar-2013, Pakhtunkhuwa-2015 and Ghanemat-2015 as un-irrigated crop for the area. The study suggests that none of the existing wheat variety has potential to sustain grain yield of wheat if planted on December 5 or thereafter. However, Ghanemat-2015 is relatively better option over the other varieties for Peshawar.
