Influence of Nitrogen and Zinc on Growth and Yield of Barley (Hordeum vulgare)

Abstract

A field experiment was conducted during Rabi 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to evaluate the influence of nitrogen and zinc on the growth and yield of barley (Hordeum vulgare), which consisted of three levels of nitrogen (50, 60 and 70 kg/ha) with zinc combination (15,20 and 25 kg/ha). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 8.0), low in organic carbon (0.62 %), available N (225 kg/ha), available P (38.2 kg/ha) and available K (240.7 kg/ha). The results revealed that significant and higher plant height (92.18 cm), maximum number of tillers /hill (5.00), higher plant dry weight (35.77 g), maximum number of effective tillers/hill (3.33), spike length (8.00 cm), grains/spike (64.07), test weight (38.02 g), grain yield (5.84 t/ha), straw yield (7.59 t/ha),  gross returns (1,29,640.00 INR/ha), Net returns (90,919.00 INR/ha) and Benefit cost ratio (2.34) was recorded in treatment 9 [Nitrogen (70kg/ha) + Zinc (25kg/ha)].
