Performance of Wheat Varieties under Minimum and Full Irrigated Condition

Abstract
A pot experiment was carried out at Amir Muhammad Khan campus Mardan, The University of Agriculture Peshawar, during winter season 2020-21 to find out the performance of wheat (Triticum Aestivum L.) varieties under drought stress conditions. The experiment was laid out in completely randomized block design with six wheat varieties and two irrigation regimes. Wheat varieties and irrigation regimes had significant effects on wheat production. The wheat cultivar Khaista-17 attained taller height (70.0cm), more number of leaves per tiller (5), higher thousand grain weight (53.1g), biological yield (9333kg ha-1), grain yield (3149 kg ha-1), harvest index (34%) and chlorophyll SPAD meter value (17) compared to the rest of cultivars. The cv. Wadan was found late in term of physiological maturity (150), and produced higher number of grains per spike (71) and number of spikelet’s per spike (20). There is non-significant difference among varieties on days to emergence and spike length. Higher days to emergence (18), plant height (67.1cm), number of leaves tiller-1 (4), days to physiological maturity (150), number of grains spike-1 (61), number of spikelet’s spike-1 (19), spike length (9.8cm), thousand grain weight (54.4g), biological yield (9271 kg ha-1), grain yield (3156 kg ha-1) and harvest index (34%) were recorded under normal irrigation although, chlorophyll SPAD value was affected under drought stress condition (14.11). Based on the current field trial, it was concluded wheat cv. Khaista-17 followed by Gulzar-19 and Wadan can be grown under irrigated conditions for higher yield of wheat. The cv. Lalma-2013 and Pirsabaq-19 although low yielding cultivars were found drought efficient being less affected by water stress in term of grain yield and hence can be grown under water stress condition. The same experiment needs to be performed in actual field for the confirmation of the results achieved in the pot experiment and estimate the losses among the cultivars under water stress conditions.
