Mono-cropping practice is predominant under rain-fed agriculture in north east India, where rice is the most important crop followed by maize. It is apparent that areas under rice and maize remain fallow during the rabi season. These fallow lands can be effectively utilized for cultivation of rabi crops with improved technology. To achieve that sowing is a critical field operation that makes the prospects of a crop. However, farmers in the region still follow traditional methods. Therefore, a light weight power tiller (4.1 kW petrol engine and 69 kg weight) operated sowing attachment was developed and its field testing was conducted. Rotor type seed metering mechanism was used in the sowing attachment. Seeds were placed in the furrows at a desire depth through adjustable system. The average depth of seed placement was 40 mm. The maximum draft requirement was 294.3 N (Inverted-T type furrow opener) which was well within the capacity of the power source. Average field capacity, efficiency and man-hour requirement per hectare were 0.068ha/h, 85 % and 14.71, respectively were for continuous operation at an average speed of 1.6 km/h. The savings in man-hours per hectare and cost of sowing were substantial as compared to conventional manual dibbling method.
