Abstract:
A field experiment was conducted at Agronomy Farm, Rajasthan College of Agriculture, Udaipur during rabi season in 2015-16 and 2016-17. The experiment consisted of 24 treatment combinations comprising of three levels of fertility (50, 75 and 100 per cent RDF), four organic sources (FYM @ 5 and 10 t ha^-1, vermicompost @ 2.5 and 5 t ha^-1), and two bio-inoculations (Without inoculation and Azotobacter + PSB). Experiment was conducted under factorial randomized block design replicated thrice taking wheat var. Raj- 4037 as test crop. Enrichment of soil with 75 per cent RDF, application of vermicompost @ 5 t/ha and dual inoculations of Azotobacter + PSB significantly increased the effective tillers/m row length, number of grains/spike, test weight, grain, straw and biological yield over 50 per cent RDF. However, nitrogen, phosphorus and potassium uptake by grain and straw as well as total uptake by crop increased significantly up to 100 per cent RDF. The maximum monetary return of ₹63688 with benefit cost ratio of 2.28 was obtained with 75% RDF, ₹64661 was found with vermicompost @ 5 t/ha and ₹ 63711 with benefit cost ratio of 2.28 was obtained with dual inoculation of Azotobacter + PSB.
