Effect of enriched farm yard manure on yield and nutrient uptake of sweet corn (Zea mays var. saccharata)

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 Glucenobacter + PSB T4: 75% RDF + Enriched FYM with Azospirillum + PSB T5: 75 % RDF + Enriched FYM with Glucenobacter + PSB T6: 100 % RDF + Enriched FYM with Azospirillum + PSB T7: 100 % RDF + Enriched FYM with Glucenobacter + PSB. The results revealed that among different treatments, cob length (cm), cob girth (cm), number of grain rows cob-1, number of grains per row, number of grains per cob, cob weight (g cob-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 N, P and K content and uptake by sweet corn at harvest.
