The experiment was conducted during the Kharif season 2022, at the Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Science, Prayagraj (U.P.) to find out the “Effect of Organic manures on growth and yield of Rice varieties (Oryza sativa L.) and yield validation using SPSS model”. The experiment was laid out in Randomized Block Design comprising of 9 treatments which include 3 varieties NDR-359, BPT-5204 and MTU-7029 and 3 organic manures Poultry manure 5(t/ha), Vermicompost 10(t/ha) and Poultry manure 2.5(t/ha) + Vermicompost 5(t/ha). Whose effect is observed in Rice varieties. The result showed that the treatment with the application of MTU-7029 + Poultry manure 2.5(t/ha) and Vermicompost 5(t/ha) at 100 DAT was recorded higher in number of tillers per hill (13.1/hill), and also recorded significant and higher number of effective tillers per hill (11.33/hill), number of grains per panicle (112.33), test weight (22.20 g), grain yield (5.21 t/ha) and straw yield (6.49 t/ha), Harvest index (44.45 %). Higher gross return (1,50,920.91 INR/ha), net return (1,00,770.91 INR/ha) and benefit-cost ratio (2.01) was recorded in the application of (MTU-7029 + Poultry manure 2.5 t/ha + Vermicompost 5 t/ha) as compared to other treatments. Treatment 9 has shown 44.68 % increase over predicted yield whereas there was 26.58 % increase in treatment 8 over predicted yield through SPSS model.
