1813 - Mechanized Transplanting Opportunities for SRI

  1. 1. Mechanize transplanting opportunities Rajendra Uprety, PhD Senior Agriculture Extension Officer Biratnagar, Nepal
  2. 2. Why mechanized transplanting?? • To benefit from the potential of younger seedlings. • To utilize available space (wider space healthier crop higher yield). • To maximize nutrient use efficiency (by mechanical weeding). • To produce more crop per drop (increase water use efficiency). • To sustain soil quality and fertility for more sustainable production system.
  3. 3. Mechanized transplanting for SRI scale-up
  4. 4. Seedbed preparation and transplanting costs.
  5. 5. 0.3 30.7 49.2 50.0 51.4 62.1 64.2 73.4 89.8 97.6 107.1 114.1 139.0 213.0 287.4 339.7 129.9 106.8 168.9 174.2 186.2 215.4 245.4 204.7 256.7 227.1 265.5 300.6 369.4 490.8 601.5 711.3 0.0 100.0 200.0 300.0 400.0 500.0 600.0 700.0 800.0 Years Labor wage and production cost of rice (1993-2014) Labor wage (Rs/man day) Total cost (US$/ha)
  6. 6. Rice farming and average cost distribution in Nepal Seed 5% Nursery Management 2% Land preparation 40% Transplanting 11% Irrigation 2% Fertilizer cost 12% Weeding 7% Harvesting+ Threshing 21%
  7. 7. Machine transplanted rice field in Morang district (2018) It was 135 days fine grain variety Yield was 8.4 t/ha Net profit was 72780 compare to 18050 by conventional method.
  8. 8. Conclusions: Mechanized transplanting for Use younger seedlings Proper spacing Mechanical weeding Labor saving Production cost reduction Profit maximization Scale-up of SRI benefits
