The study was carried out the evaluating the performance of improved cultivars with scientific package and practices under direct seeded rice (DSR) on production as well as productivity and profitability of aerobicrice. Frontline demonstrations were conducted during 2016-17 and 2017-18 efforts has been made for resource conservation in rice by introducing direct seeded rice (DSR) and short duration rice varieties viz. MTU-1010, Indira Barani Dhan-1, IGKV R-1 and IGKV R-2 in Raigarh and Pussore blocks of the district and record feedback information of farmer’s. The results revealed that average grain yield of rice varieties under frontline Demonstrations were IGKV R-1 (46.33 qha-1), IGKV R-2 (45.14 qha-1), MTU-1010 (44.53 qha-1) and Indira Barani Dhan-1(42.71 qha-1) as compare to 34.50, 33.85, 34.60 and 32.35 qha-1 recorded in farmer’s practice, average yield increase of 34.29, 33.35, 28.70 and 32.02 per cent, respectively. The average extension gap 10.85 qha-1 and average technology gap 4.07 qha-1 was recorded. The technology index for four varieties ranges between 5.09 to 10.94 per cent with an average 8.27 percent only which gives a clear indication that technology is highly viable for this region. Additional return of 11145.00 and 14614.00 Rsha-1, respectively. It was observed that the average additional return 15283.00 Rsha-1 and average benefit cost ratio (B:C) of recommended practice (FLD) 2.70 as compared to 2.16 in farmer’s practice during consecutive years of study blocks. Direct seeded rice (DSR) alternative establishment method to sustain productivity of rice as well as natural resources. It offers certain advantages viz., less labour, less water requirement, less drudgery, early crop maturity, low production cost, proper placement of seed and fertilizer, increase fertilizer use efficiency, improve soil health for crops and less methane emission, in different cropping systems. Direct seeded rice can be obtained by adopting various package and practices viz., selection of suitable cultivars, timely sowing, optimum seed rate, proper water and weed management and plant protection measures. Therefore, the results clearly indicate that the use of improved varieties and package and practices with scientific intervention under frontline demonstration programme contribute to increase the productivity and profitability of rice in Chhattisgarh state.
