A field study aimed to assess different weed management tactics in transplanted rice was demonstrated during rainy season in four villages of Ganjam district of Odisha under farmer participatory mode for two years (2019 and 2020). From the concluded research work, it was observed that application of pretilachlor (0.75 kg/ha) within 3 DAT followed by bispyribac sodium @ 25kg/ha at 25 DAT recorded the highest WCE (73.27%), grain (4186 and 4351 kg/ha) and straw yield (5349 and 5308 kg/ha). Hand weeding performed better with respect to WCE (80.1, 81.3 % at harvest) but net return (Rs. 37073 /ha, Rs. 38119 /ha) was found to be low. While Pretilachlor (0.75 kg/ha) within 3 DAT followed by bispyribac sodium (25 kg/ha) at 25 DAT recorded the highest net return (Rs. 41798/ha, Rs. 43956 /ha) and B:C ratio (1.87, 1.89) than other treatments.
A continuous 3 year demonstration using drought tolerant rice variety Swarna Shreya was carried out in participatory mode in farmers’ field during Kharif season 2019, 2020 and 2021 at Lathipadsa village of Surada block of Ganjam district under north-eastern ghat zone of odisha. Major constraints of traditional rice cultivation are the low productivity in upland areas due to lack of knowledge and partial adoption of recommended package of practices by rice growing farmers. Also because of less water sometime farmers do not take any crop. Therefore, present demonstration programme has been undertaken to popularize/introduce stress tolerant rice var. Swarna Shreya in drought prone and upland areas of Ganjam district of Odisha. An average yield of 38.33 q ha-1 was recorded under demonstration plots as compared to 32.17 q ha-1 in farmers practice plots. The yield improvement due to the improved practices was 18.69 percent over farmers' practice. Average technology gap, extension gap, technology index was 6.67 q ha-1,6.17 q ha-1, 14.81 percent under three year frontline demonstration programme were recorded. The stress tolerant rice variety Swarna Shreya gave higher net return of Indian Rupee (INR) 33500, 40655 and INR 45350 ha-1 as compared to farmers practices with INR 26100, 23520 and 24650 ha- 1 during Kharif season of 2019, 2020 and 2021, respectively. The benefit cost ratio (B:C ratio) of rice cultivation under improved practices were found to be 1.95, 2.13 and 2.08 as compared to 1.67, 1.60 and 1.58 under farmers practices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
