Abstract:
The experiment conducted at farmer field at Sonwahi village Ambikapur entitled “Influence of fertilizer levels on yield and NUE by rice in an Inceptisol” during kharif 2021. Field experiment was laid down in randomized block design using rice cultivar MTU 1156 as test crop, allocated randomly five fertilizer treatments T₁(control), T₂(50% RDF), T₃(100% RDF), T₄(150% RDF), T₅(100% RDF +5 t ha^-1) with five replications. The yield attributing parameters viz. plant height, effective tiller^-1 were found highest with applied level of 150% RDF. The highest grain and straw yield (61.80 q ha^-1 and 75.45 q ha^-1) were found with applied RDF level at 150% was at par with 100% RDF + 5 t ha^-1 FYM (60.48 q ha^-1 and 74.33 q ha^-1). Maximum nitrogen, phosphorus, potassium uptake (100.11, 21.52, 165.97 kg ha^-1) of applied fertilizer i.e. 150% RDF. The nitrogen and phosphorus use efficiency were recorded with applied 50% RDF (40.40% and 18.15%). The highest potassium use efficiency was obtained at level of applied 50% RDF. The overall finding showed that use of 150% RDF at par with 100% RDF + 5 t ha^-1 FYM increased the growth and yield attributes parameters of rice. Hence the farmers may apply 150% RDF doses for maximization of rice yield but may reduce N, P & K fertilizer doses with application of 5 t ha^-1 FYM with 100% RDF for similar yield.
