A field study was conducted during kharif and rabi season of 2015 - 16 and 2016 - 17 at the Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur. Fifteen treatment combinations (viz., five tillage practices and three weed management) were tested in split plot design with three replications to assess the productivity of rice under rice – maize cropping system, to evaluate conventional tillage - transplanted rice options as compared to conventional tillage - direct seeded rice with an objective to improved yield also comparison between zero tillage - direct seeded rice superior over to conventional tillage - direct seeded rice during second year. Labour saving 95 % and cost saving 32 and 40 % were observed in conventional tillage - direct seeded rice and zero tillage - direct seeded rice, respectively as compared to conventional tillage transplanted rice. Tillage and weed management practices had significant effect on rice yield. Yield of conventional tillage - transplanted rice was significantly higher (44 and 35 %, respectively) than conventional tillage - direct seeded rice and zero tillage - direct seeded rice. The B: C ratio was highest in zero tillage - direct seeded rice (2.21) as compared to conventional tillage - direct seeded rice (1.61) and conventional tillage - transplanted rice (1.58). Conventional tillage - transplanted rice compulsory more input energy and produced more output energy. Conventional tillage - transplanted rice obtained maximum energy use efficiency and energy productivity during both the years it was similar zero tillage - direct seeded rice during second year. The study showed that the conventional practices of puddle transplanted rice could be replaced with zero tillage - direct seeded rice to save labour and energy cost.
