Abstract:
An on-farm survey was conducted during kharif 2019 and 2020 in Siddipet district of Telangana, India to study the comparative analysis and impact of conventional and machine transplanting and harvesting/threshing in rice on labour, time and energy use pattern besides productivity and economics. The survey results revealed that mechanical transplanting helped in timely completion, better yield attributes like more no.of tillers/ hill (21), no. of panicles/ hill (21), grains /panicle (215) and 1000 grains weight (17.4.0 g) and yield besides less incidence of insect pests and diseases due to maintenance of proper and uniform spacing (30cm×14 cm) and less no. of hills /m² (22). Machine transplanting and harvesting saved 6.25 hours’ time, 70 man days, cost of cultivation of Rs. 9,154 per hectare besides higher yield (4%) and energy use efficiency (5%) over conventional methods.
