ABSTRACT:

Large population in India consume rice as staple food and are suffering from type-2 diabetes. In general, most of the rice varieties have the GI of around 73 (white rice – polished) and 68 (brown rice – unpolished) which is responsible for a person to become diabetic. The rice variety RNR 15048 developed by Professr Jayashankar Telangana State Agricultural University is having Glycemic index of 51%. On farm trials were conducted during Kharif 2009 with low GI rice variety RNR 15048 in 290 farmers’ fields of 10 villages of Gajapati district, Odisha. The farmers adopted both dry seeding and transplanting method of crop establishment, used different aged seedings for transplanting between July 16 to Aug 31 and applied varying levels of fertilizer. There was an increase of 5 % of paddy in dry seeded crop over that of transplanted crop. The grain yield of the crop sown between July 1 to 15 has recorded   26 and 11% higher yield (4228 kg ha-1) than that of June 10-20 and June 20 to 30 respectively. The mean yield improvement observed was 3 % at higher N and P2O fertilizer application (113 kg N and 58 kg P2O5 ha-1) (4379 kg ha-1) as compared to low N and P2O fertilizer applied (43 kg N and 23 kg P2O5 ha-1). The grain yield of rice was higher with transplanting between 16 to 31 July (5092 kg ha-1) which was 18, 21 and 49 % higher over that transplanted between Aug 1 to 10, 11to 20 and 21to 31. There was decrease in grain yield with increase in average age of seedlings from 30 to 36 and 43 days. The grain yield of transplanted rice was higher in Lingipur village where soil N and P were lower as compared to village Chandanakhala where soil fertility was higher and grain yield was lower than that in former village.
