Abstract
Application of phosphorus and soil amendment with beneficial microbes is important for increasing barley yield. The current research was conducted at the Agronomy Research Farm, The University of Agriculture Peshawar, during winter 2020-21. The experiment comprised of beneficial microbes (with and without beneficial microbes) and phosphorus application (0, 40, 60 and 80 kg ha-1). Experiment was arranged in the randomized complete block design having four replications. In case of the beneficial microbes, maximum days to emergence (15), days to heading (115), days to anthesis (125), days to physiological maturity (159), leaf area tiller-1 (118.9 cm2), tillers m-2 (286), plant height (92.4 cm), spike length (10.9 cm), spikes m-2 (265), spikelets spike-1 (21), grains spike-1 (48), thousand grains weight (43.6 g), biological yield (8925 kg ha-1), grain yield (3816 kg ha-1) and harvest index (42.7%) as compared to control. Among the phosphorus application, maximum days to heading (115), days to anthesis (125), days to physiological maturity (159), leaf area tiller-1 (121.6 cm2), tillers m-2 (285), plant height (91.3 cm), spike length (10.7 cm), spikes m-2 (263), spikelets spike-1 (21), grains spike-1 (47), thousand grains weight (43.1 g), biological yield (8874 kg ha-1), grain yield (3773 kg ha-1) and harvest index (42.5%) were recorded when phosphorus was applied at the rate of 60 kg ha-1 before sowing. It was concluded that application of phosphorus at the rate of 60 kg ha-1 and soil amendment with beneficial microbes increased barley yield in the agro-ecological conditions of Peshawar.
