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.
