Nutrient content and uptake as influenced by different varieties and nitrogen levels in barley (Hordeum vulgare L.) under saline water irrigation

Abstract

Due to scarcity of irrigation water in Haryana, the field experiments were conducted during rabi seasons of 2017-18 and 2018-19 at Hisar to study the influence of different varieties (BH902, BH 946, BH 885 and DWRB 101) and nitrogen levels (0, 30, 60 and 90 kg ha-1) on nutrient content and uptake in barley under saline water irrigation. Barley variety BH 902 recorded maximum N content in grain and straw (1.67 and 0.51 %, respectively) in comparison to BH 946, BH 885 and DWRB 101. Six rowed barley varieties BH 902 and BH 946 recorded significantly higher N, P and K uptake as compared to two rowed barley varieties BH 885 and DWRB 101. All the nitrogen levels significantly enhanced the N content in grain and straw as compared to control, whereas P and K content in grain and straw was not significantly influenced by different varieties and nitrogen levels. The N uptake by grains, straw and total N uptake increased significantly with each increment of nitrogen dose up to 90 kg ha-1, while total P and K uptake was significantly increased only up to 60 kg ha-1.
