Abstract:
Fourteen INM treatment viz.100% RDF, 100% RDF + FYM @ 20.0 t ha^-1, 100% RDF + PSB, 100% RDF + PSB + ZnSO₄ @ 12.5 kg ha^-1, 75% RDF, 75% RDF + Vermicompost @ 5.0 t ha^-1, 75% RDF + Vermicompost @ 2.5 t ha^-1, 75% RDF + Vermicompost @ 2.5 t ha^-1 + PSB, 75% RDF + Vermicompost @ 2.5 t ha^-1 + ZnSO₄ @ 12.5 kg ha^-1, 75% RDF + FYM @ 20.0 t ha^-1, 75% RDF + FYM @ 10.0 t ha^-1, 75% RDF + FYM @ 10.0 t ha^-1 + PSB, 75% RDF + FYM @ 10.0 t ha^-1 + PSB + ZnSO₄ @ 12.5 kg ha^-1, Control (untreated) were carried out in randomized block design with three replications and experiment was conducted at College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner during Rabi 2019- 2020. The results exhibited that the application of 75% RDF+FYM @ 10.0 t ha^-1 +PSB+ ZnSO₄ @ 12.5 kg ha^-1 was recorded significantly higher dry matter accumulation, leaf area index, crop growth rate and relative growth rate over rest of treatment but which was at par with 100% RDF + FYM @ 20 t ha^-1, and 75% RDF + FYM @ 20 t ha^-1. A significant and positive correlation also existed between fodder yield with growth, yield attributes and nutrient uptake of oats. The regression equations show that every unit increase in growth and yield attributes also increase the fodder yield of oats.
