Effect of Different Seed Rates and Nitrogen Levels on Growth and Yield of Barley (Hordeum vulgare L)

The trial was conducted to evaluation the effect of seed rate and nitrogen levels on growth and yield in barley crop, field experiment was carried out in 2020-21 growing seasons. Experimental units were arranged in Factorial Randomized Block Design (RBD) with three replications. The highest value of growth parameters were obtained in the application of 80 kg ha-1 seed rate with nourishing of 120 kg nitrogen ha-1. All of the growth characters viz. plant height (cm), number of functional leaves plant-1 (at 90 DAS), number of tillers plant-1 and dry weight (g) plant-1 at harvest and yield attributes i.e., length of ear (cm), number of grains ear-1 and weight of ear (g) were found significantly maximum with the application of seed rate 80 kg ha-1 in combination of 120 kg nitrogen ha-1. The significant highest seed yield 40.94 q ha-1 was calculated with application of 100 kg ha-1 seed rate which was 1.75%, 1.58% and 2.64% more over application of 110 kg, 90 kg and 80 kg ha-1 seed rate. Increasing level of nitrogen significantly enhanced seed yield, the 120 kg ha-1 nitrogen application gave highest seed yield i.e., 43.63 q ha-1 over other nitrogen levels i.e., 100 kg, 80 kg ha-1 and the control. The highest benefit cost ratio 1.34 was calculated with 100 kg of seed rate and 1.39 in respect of 120 kg ha-1 nitrogen level.
