Abstract:
A field experiment was conducted at Instructional Research Farm, Krishi Nagar, Adhartal, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (MP) during the Kharif season of 2019-20 and 2020-21 to evaluate the different rice varieties under organic farming in Kymore Plateau and Satpura Hills Zone. The experiment was carried out using randomized block design with three replications involving twelve rice varieties viz., Pusa Sugandha 5, Sahyadri, Pusa Sugandha 4, Pusa Sugandha 3, Pusa Basmati 1, Danteshwari, Madhumati, BVD 109, JR 201, IR 36, MTU 1010 and IR 64. The recommended dose of NPK @ 120:60:40 kg per ha respectively was applied through FYM, Neem cake and Vermicompost, each 1/3^rd on the basis of nitrogen content. Grain and Straw yields varied significantly among the above-mentioned rice varieties. Rice variety IR 64 recorded the maximum grain yield and straw yield closely followed by Pusa Sugandha 3, whereas significantly superior over other varieties. However, the minimum grain yield and straw yield was noted in Danteshwari. While considering economic aspects of different rice varieties with the common cost of cultivation, the GMR and NMR were recorded maximum in PS 3 (Rs. 157330 and 93414 ha^-1 respectively) and minimum in Danteshwari (Rs. 75050 and 11134 ha^-1 respectively). With regard to the B:C ratio, markedly highest profitability was noted in the rice variety PS 3 (2.46) as compared to other varieties.
