Abstract
The trial was conducted at Crop Research Farm, Department of Agronomy of Naini Agricultural Institute, SHUATS, Prayagraj (U.P), during Kharif 2021.The experiment was bifactorial (two factors) which consists of three different planting methods i.e., Direct seeded rice, Transplanted rice and SRI method, and three different weed management practices i.e., Hand weeding (twice), Oxadiazon 25 EC (as Pre emergence) at 250g/L (2L/ha) and Pyrazosulfuron ethyl 10% WP at 20g/ha (as Post Emergence) and a control plot laid out in randomized block design with ten different treatment combinations which is replicated thrice. The results revealed that at harvest significantly, higher growth attributes like plant height (117.28 cm), Number of tillers (38), plant dry weight (56.36 g/hill) at harvest is recorded in treatment number 7 with a combination of SRI method of planting and Hand weeding twice at critical crop weed competition. Significantly, higher yield attributes like number of effective tillers/ hill (35), number of panicles/ plant (44), number of grains per panicle (216.6), test weight (25 g), grain yield (5.1 t/ha) and straw yield (8.1 t/ha) was highest in the same treatment. From the experiment it can be concluded that treatment 7 where SRI method of planting and hand weeding twice during critical crop weed competition was considered as best treatment combination with maximum effective tillers/hill, number of panicles/plant, number of grains per panicle, test weight, grain yield and straw yield i.e., all the yield attributes.
