Abstract
Drought is the most important factor limiting plant production in the majority of agricultural crops of the world. Wheat is generally grown on arid-agricultural fields. An experiment was conducted at the Plant physiology research area, Agronomic Research Institute Faisalabad, during winter 2010-11 to evaluate the effect of drought on wheat variety Lasani 2008. The experiment was comprised of following treatments. T 1 Normal moisture (3 IR at CRS, Booting and grain filling), T 2 No irrigation (only rainfed) control, T 3 water spray (100 ppm), T 4 ascorbic acid (100 ppm), T 5 salicylic acid (100 ppm), T 6 calcium chloride (100 ppm), T 7 glycinbetain (100 ppm). According to the resulting data the treatment in which three irrigation were applied produced more no. of tillers (52%), spikelet per spike (41%), spike length (30%), grain per spike (58%), grain yield (54%), biological yield (35%) as compared to control. The treatment in which no irrigation was applied produced less no. of tillers, spikelet per spike, spike length, grain per spike, grain yield, biological yield. Thousand grain weight and harvest index were non significant among all treatments.
