Influence of Chemical Fertilizer and Organic Manure on Enhancing the Production of Barley (Hordeum vulgare L.) Crop in Himachal Pradesh, India

Abstract

A field experiment was conducted at the Research Farm, School of Agriculture, Abhilashi University, Chail Chowk Mandi during the Rabi season of 2022-23 to look into the “Influence of chemical fertilizer and organic manure on enhancing the production of barley (Hordeum vulgare L.) crop in Himachal Pradesh”. During the investigation seven treatment combination were employed in randomized block design with three replications. Treatment comprises of T1 (Absolute control) T2 (RDF 100% + FYM 5 t ha-1), T3 (75% RDF + FYM 5 t ha-1), T4 (125% RDF + FYM 5 t ha-1), T5 (150% RDF + Zinc @ 1 kg ha-1), T6 (50% RDF + 50% FYM) & T7 (50% RDF + 25% FYM + 25% VC). The finding of the experiment showed that different integrated nutrient treatments had significantly improved the production and productivity of barley crop. The highest plant height (65.75), (82.44) and (86.65) was observed in treatment T5 (150% RDF + Zinc @ 1 kg ha-1). No. of tillers (450.34), (437.64) and (425.48) and dry matter accumulation (450.11), (600.33) and ( 795.66). The yield attributes i.e., No. of effective tillers (419.33), Spike length (8.27), No. of spikes (417.84), Grains per spike (45.57) and grain yield (44.23), straw yield (67.39) and biological yield (111.62) were also significantly influenced by the treatment T5 which was at par with T4 and T2 . During investigation minimum value of all the growth and yield parameters and yield was observed under treatment T1 i.e. absolute control. From the observation it was found that combination of organic and inorganic fertilizer significantly improve production and productivity of barley.
