Response of planting methods and micronutrient on growth and yield of rice (Oryza sativa L.) North East plan zone Prayagraj

Abstract

The research work was conducted at the Agronomy Research Field, United University, Prayagraj (U.P.) during Kharif season from June to December, 2023 to study the effect of planting methods and Micronutrient on the growth and yield of rice. The experiment consisted of three planting methods treatments viz. SRI method, Line sowing method and Transplanting method and three Micronutrient viz. FeSo4 (5%), Zn + B (5%) and Seaweed sap (10%). The experiment was laid out in randomized block design with three replications. The highest plant height (104.19 cm), Number of tiller/hill (32.03), Plant dry weight (64.98 g/plant), Yield attributes No. of panicle/hill (15.37), panicle length (32.24 cm), No. of grain/panicle (140.57), days to maturity (137.23) and Test weight (27.63 g) was recorded in treatment T9 (Transplanting method + Seaweed sap (10%)) while highest Seed yield (5.31 t/ha), Straw yield (12.96 t/ha), Biological yield (18.27 t/ha) was recorded in treatment T9 (Transplanting method + Seaweed sap (10%)) of rice. The highest economics was computed under treatment T9 (Transplanting method + Seaweed sap (10%)) i.e. net return (123089.46 Rs/ha), gross return (178635.50 Rs/ha), highest cost of cultivation (55546.04 Rs/ha) and (B: C ratio) (2.22). The lowest plant height (84.33 cm), Number of tiller/hill (27.30), Plant dry weight (45.23 g/plant), Yield attributes, No. of panicle/hill (10.34), panicle length (23.46 cm), No. of grain/panicle (105.93), Test weight (22.33 g), Seed yield (3.98 t/ha), Straw yield (9.71 t/ha), Harvest index (29.20 t/ha), of rice. The lowest net return was computed under T10 (100% RDF Control) and net return (81035.46 Rs/ha), gross return (133831.50 Rs/ha), lowest cost of cultivation (52796.04 Rs/ha) recorded in (B: C ratio) (1.53) Therefore, T10 (Control) obtaining the highest grain and straw yields of rice.
