  • Conventional method: 313; Mechanized method: 226 US$/ha.
  • Average of conventional method: 4.2 t/ha and Mechanized method: 4.8 t/ha
  • Profit 602-817 US$/ha (289-591 US$ net profit over conventional method.)
  • Weeding labor for mechanical weeding was 15 and for conventional manual weeding it was 24.

    1. 1. Meshing mechanization with SRI methods for rice cultivation in Nepal Presented in 3rd International Rice Congress 2010 8-12 November 2010, Hanoi, Vietnam Rajendra Uprety Senior Agriculture Development Officer Department of Agriculture Nepal
    2. 2. Rice Cultivation in Nepal
    3. 3. Problems of rice cultivation in Nepal Low yields High production costs Labor shortages Water shortages for irrigation Manual/bullock-based cultivation To solve some of the above mentioned problems, the System of Rice Intensification (SRI) has been introduced to raise factor productivity and reduce water requirements. But even though SRI raises labor productivity, its labor requirements often limit its adoption.
    4. 4. Mechanization of rice farming  Mechanization is being introduced in Morang district of eastern Nepal in conjunction with SRI practices.  In the first year, 27 farmers participated with 24 ha area under mechanized rice farming  Machines were used for land preparation, transplanting, and harvesting work.  Machines were provided by Buddha Air, but all cost has calculated, and a fixed rent for these machines was paid by farmer users

    12. 12. Conclusions Mechanization of rice farming can reduced labor requirements and production costs, and it will be a good solution for Nepalese rice farmers who are faced with labor shortages and high costs of production Mechanization can reduce the costs of land preparation, transplanting, and harvesting. Farmers can cut down on their labor costs for weeding if and when they have access to appropriate weeders at an affordable cost.
    13. 13. Conclusions (continued) Those farmers who are familiar with SRI methods were able to scale-up their SRI practice with some modification. The results show that a combination of mechanization and SRI can increase production and further enhance farmer income by reducing production cost. Besides this, Nepalese farmers who can save valuable time by mechanization then can take on other additional work for bettering their livelihoods.
