Rice production from upland areas has an important contribution in total rice production and it is mainly cultivated in rainfed condition in rainy season. The present study was conducted during kharif season of 2021 in Malkangiri district of South Eastern Ghat Zone of Odisha to evaluate the performance of different upland varieties (Mandakini, CR Dhan 202 and CR Dhan 200) in relation to existing variety (Sahabhagi dhan). Rice variety Sahabhagi dhan was considered as local check (farmer’s practice). Performance of CR Dhan 200 was better in terms of plant height (122.5 cm), number of tillers/m2 (299.8), panicle length (22.3 cm), number of grains/panicle (141.2), test weight (22.5 g) with highest yield (43.5 q/ha). In terms of yield, it was 7.1-13.0% more with CR Dhan 200 as compared to others varieties. Highest economic return with more B: C ratio (1.99) was also recorded with CR Dhan 200. So, rice variety Sahabhagi dhan can be replaced with CR Dhan 200 for more yield and higher economic return in rainfed upland ecosystem of South Eastern Ghat Zone of Odisha.
• Better growth and yield attributes along with more yield and higher economic return were observed with rice variety CR Dhan 200.
• CR Dhan 200 may be replaced with existing Sahabhagi dhan for higher production and more economic return for farmers of South Eastern Ghat Zone of Odisha in rainfed upland ecosystem.
