Abstract

A field experiment was conducted during Kharif-2023 at Agricultural Research Station, Dhadesugur to study the effect of enriched farm yard manure on growth and yield of sweet corn. The experiment consisted of seven treatments viz., T1: 100% RDF T2: 50% RDF + Enriched FYM with Azospirillum + PSB T3: 50% RDF + Enriched FYM with Gluconobacter + PSB T4: 75% RDF + Enriched FYM with Azospirillum + PSB T5: 75% RDF + Enriched FYM with Gluconobacter + PSB T6: 100% RDF + Enriched FYM with Azospirillum + PSB T7: 100% RDF + Enriched FYM with Gluconobacter + PSB. The results revealed that among different treatments, growth parameters such as plant height (204.4 cm), number of leaves (13.6), leaf area (5033 cm2), leaf area index (3.82), and dry matter production and its accumulation in different plant parts (243.9 g plant-1) were significantly higher with application of 100% RDF + enriched FYM with Gluconobacter + PSB which in turn resulted in significantly higher fresh cob yield (175.6 q ha-1) and green fodder yield (224.8 q ha-1). Further, the same treatment recorded significantly higher gross returns (₹1,98,080 ha-1) net return (₹ 1,46,230 ha-1) and benefit-cost ratio (3.89).
