In Odisha, about 40 lakh ha area covered under rice crop, which occupies about 24 percent of gross cropped area of the country. The district, Malkaangiri comes under South Eastern Ghat zone of Odisha and rice productivity in this district is low (31.2q per ha) as compared to state average . It .has been identified that climatic and biotic factors like Brown plant Hopper (BPH) pest incidence sometimes resulted to severe yield loss . Farmers’ participatory field trials were carried out in two blocks like Malkangiri and Korkunda of Malkangiri district to study the performance of BPH tolerant rice variety Hasanta and farmers ruling variety Pratikshya was taken as check. The field experiment was conducted during Kharif -2019 and 2020, in farmers’ field in three adopted villages comprising 30 no of farmers, 10 from each village. The BPH incidence was significantly less in rice variety Hasanta. The result revealed that maximum number of tillers/ m2, panicle length, plant height and no of grains per panicle were rerecorded higher in Hasanta as compared to farmer’s variety. It was observed that the average grain yield of rice variety Hasanta was 43.8 q ha-1 as compared to farmer’s variety Pratikshya 39.3 q ha-1 and yield was 12 % higher over farmer’s variety So, it was revealed that, performance of BPH tolerance rice variety Hasanta under rain fed condition was consistent and exhibited tolerance to BPH incidence . It was concluded that Hasanta can substitute farmer’s variety Pratikshya under rain fed semi-low land rice ecosystem with substantial higher yield and tolerance to BPH incidence , with higher net return .
