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. T1 Normal moisture
(3 IR at CRS, Booting and grain filling), T2 No irrigation (only
rainfed) control, T3 water spray (100 ppm), T4 ascorbic
acid (100 ppm), T5 salicylic acid (100 ppm), T6 calcium
chloride (100 ppm), T7 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.
