Abstract:
A study on “Effect of organic and inorganic fertilizer on growth and yield of hybrid paddy (Oryza sativa L.)”. Research was carried out at Rama University in Kanpur, Uttar Pradesh, India, during the kharif season in the year 2022. Three replications and a Randomized Block design were used to set up the experiment. Eight treatments viz T₁-Control (No application of fertilizer), T₂-50% Nitrogen (Urea), T₃-75% Nitrogen (Urea), T₄-100% Nitrogen, T₅-50% RDF + Vermicompost (1.5 t ha^-1), T₆-50% RDF + Green leaf Manure (1.5 t ha^-1) + Vermicompost (1.5 t ha^-1), T₇-75% RDF +Green leaf Manure (1.5 t ha^-1) + Vermicompost (1.5 t ha^-1) and T₈-75% RDF + Green leaf Manure (2.5 t ha^-1)+ Vermicompost (2.5 t ha^-1) + PSB were allocated in randomly. Higher growth attributing characters at different crop stages and yield attributing characters at harvest viz. plant height, dry matter accumulation, No. of tillers m^-2, & number of panicles m^-2, panicle length (cm), test weight number of grains panicle^-1 were produced in rice with 75% RDF + Green leaf Manure (2.5 t ha^-1)+ Vermicompost (2.5 t ha^-1) + PSB treatment. Similarly, higher grain, straw yield highest harvest index, quality parameters (protein) along with maximum uptake of nutrient & net monetary income was recorded under combination of organic and inorganic fertilizer’s (75% RDF + Green leaf Manure 2.5 t ha^-1 + Vermicompost 2.5 t ha^-1 + PSB) dosses in rice crop. In terms of benefit cost ratio treatment T₇-75% RDF + Green leaf Manure (1.5 t ha^-1) + Vermicompost (1.5 t ha^-1) was produced maximum B: C ratio.
