Impact of integrated nutrient management on growth and yield of barley (Hordeum vulgare L.)

Abstract

A field study entitled “Effect of Integrated Nutrient Management on the Productivity of Barley (Hordeum vulgare L.)” was conducted during the rabi season of 2024-25 at the Agricultural Research Farm, School of Agricultural Sciences, Jaipur National University, Jaipur (Rajasthan). The experiment was arranged in a Randomized Block Design (RBD) with three replications. The field trial consisted 10 treatments combinations viz., (i) control, (ii) 40 kg N ha-1, (iii) 80 kg N ha-1 and (iv) 100% RDF ha-1, (v) 75% RDF ha-1, (vi) 75% RDF + 30 kgZnSO4 ha-1, (vii) 75% RDF+ 5t FYM ha-1 + 30 kgZnSO4 ha-1 (viii) 50% RDF ha-1, (ix) 50% RDF+ 30 kgZnSO4 ha-1 and (x) 50% RDF+ 5t FYM ha-1 + 30 kgZnSO4 ha-1. The result showed that higher growth parameters viz., plant height, number of tillers meter-1 row length, DMA, CGR and RGR and maximum yield attributes and yield viz., spike length (9.80), number of grains spike-1 (44.50), test weight (42.80 g), grain yield (2490 kg ha-1) and straw yield (3520 kg ha-1) of barley recorded with the application of 100% RDF and found at par with the application of 75% RDF + 5 t FYM ha-1 + 30 kg ZnSO4 ha-1.
