Effect of Varieties and Organic Manure on Growth and Yield of Rice (Oryza sativa L.)

Abstract

The field experiment was conducted during kharif 2022 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P). The soil texture of experimental plot was sandy loam neutral in soil reaction (pH 7.1), low in organic carbon (0.36 %), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design (RBD) with nine treatments including control each replicated thrice based on one year experimentation. The treatments consist of T1: NDR 359 + FYM 10t/ha, T2: NDR 359 + Poultry manure 2t/ha, T3: NDR 359 + Vermicompost 5t/ha, T4: Sahbhgi Dhan + FYM 10t/ha, T5: Sahbhgi Dhan + Poultry manure 2t/ha, T6: Sahbhgi Dhan + Vermicompost 5t/ha, T7: Arize 6444 + FYM 10t/ha, T8: Arize 6444 + Poultry manure 2t/ha, T9: Arize 6444 + Vermicompost 5t/ha are used. The application of NDR 359 + Poultry manure 2t/ha recorded significantly higher Plant height (107.67 cm), Number of tillers/hill (15.90), Plant dry weight (88.03 g/hill), maximum panicles/hill (10.67), number of grains/panicle (98.70), Test weight (20.68 g), grain yield (5.40 t/ha), straw yield (7.07 t/ha), Harvest index (43.31 %). Higher gross returns (1,66,674.00 INR/ha), net return (1,10,314.2 INR/ha) and benefit cost ratio (1.96) was obtained in the treatment of NDR 359 + Poultry manure 2t/ha.
