Effect of Different Irrigation Schedules on The Growth and Yield Performance of Wheat (Triticum aestivum L.) Varieties Assessment in District Awaran (Balochistan)

Abstract

The field experiment was carried out to investigate the effect of different irrigation schedules on growth and yield Performance of wheat varieties assessment in district Awaran Balochistan was conducted at Tehsil Mashkai District Awaran, Balochistan during Rabi 2012-13. The experiment was layout in a three replicated randomized complete block design (Factorial) having net plot size of 6.0 m². Three wheat varieties i.e. Sassui, TD-1 and Raskoh-2005 were evaluated for their performance against three irrigation schedules i.e. five irrigations (1^st 25 DAS and subsequent irrigations at 15 days interval), four irrigations (1^st 30 DAS and subsequent irrigations at 20 days interval) and three irrigations (1^st 35 DAS and subsequent irrigations at 25 days interval). The results showed that plant height, differed highly significantly (P<0.01) for irrigation schedules, and non-significantly (P>0.05) for verities and interaction. Spikelet’s spike^-1 and seed index highly significant (P<0.01) for irrigation and verities whereas non-significantly (P>0.05) for interaction. Tillers, spike length, grains spike^-1, biological yield and grain yield showed highly significant (P<0.01) effects for irrigation schedules, varieties and their interaction, whereas harvest index was influenced highly significantly (P<0.01) between irrigation schedules and varieties and significantly (P<0.05) for their interaction. The wheat crop irrigated five times resulted maximum plant height (86.206 cm), tillers m^-2 (402.11), spike length (12.040 cm) spikelet’s spike^-1 (18.979), grains spike^-1 ( 47.099), seed index (44.580 g), biological yield, (13732 kg ha^-1), grain yield (6999.30 kg ha^-1) and harvest index (50.95%) as compared to four irrigations and three irrigations. Among varieties Sassui ranked 1^st in all traits studied particularly grain yield (5818.80 kg ha^-1) followed by TD-1 (5407.4 kg ha^-1) and Raskoh-2005 (5014 kg ha^-1). However, it is concluded that interaction of five irrigations and wheat variety Sassui proved optimum for obtaining maximum grain yield (7444.70 kg ha^-1).
