Paddy is the principal crop and the central plains of Chhattisgarh are known as rice bowl of central India. It is a labour intensive crop and requires about 800 to 900 labour-hours for cultivating one hectare of land. Of different field operations, seeding through seed drills, transplanting, weeding through mechanical weeder and harvesting together consume major labour force and if these are managed timely and efficiently by the farmers, could earns good profit. To access the performance of machines used in cultivation of rice an experiment was conducted at Krishi Vigyan Kendra, Kanker. For mechanical transplanting a self propelled rice planter and line sowing under wet conditions with an eight row paddy drum seeder whereas for weeding manually operated weeder and a self propelled paddy reaper for harvesting of paddy were also evaluated. An eight row self propelled paddy transplanter was found to be very effective for timely transplanting in a large area. Its average field capacity was 0.192 ha/hr and cost of transplanting almost 61 % less compared to manual transplanting. Use of manually operated 8 row drum seeder tested was most effective for line sowing of sprouted paddy in puddled condition. It reduces the cost of cultivation by saving 58 % seed compared to farmers practice. It was observed that the average cost of mechanical transplanting with an eight row self propelled rice transplanter 74.71 %, mechanical weeding with ambica paddy weeder was 51.15% and mechanical harvesting with a self propelled vertical conveyer reaper was 59.76% less as compared to manual transplanting, weeding and harvesting operations respectively.
