Abstract
A study was conducted in farmer’s field through technology demonstrations during Kharif season of 2018 and 2019 in Subarnapur district of Odisha to recommend the most suited short duration drought tolerant upland rice variety particular to the locality. Six different varieties like Sahabhagi dhan, Mandakini, Jogesh, DRR-44, and DRR-42 & Khandagiri were taken with four replications in Randomized Block Design in both years. Technology demonstration included not only the improved short duration varieties, but also a package of good agronomic practices viz. line sowing, seed treatment with Bavistin, proper fertilization with dose @ 80:40:40 NPK/ha, pre emergence herbicide application with pretilachlor, needful manual weeding and need based plant protection chemicals. The results of demonstration showed that farmers could increase rice productivity notably by adopting improved variety Sahabhagi dhan and DRR-44. These varieties recorded higher grain yields of 64% and 46%, respectively, and fetched a sum return of Rs 25620 and Rs 25275 over farmers’ local variety Khandagiri.
