0637 Comparison of the System of Rice Intensification with Conventional Practice in Dung Toung, Kampot Province
1. COMPARISON OF THE SYSTEM OF RICE INTENSIFICATION WITH CONVENTIONAL PRACTICE IN DUNG TOUNG, KAMPOT PROVINCE By : Mr. CHUONG Sophal : Mr. SRAS Phanny Supported by Cambodian Agricultural Research Fund (CARF)
2. Objectives To study on the conventional practices To study the system of rice intensification (SRI) Comparison the System of Rice Intensification (SRI) and Conventional Practice Economic analysis
6. Data collection is divided into two steps: 1-Primary data : interview with farmers. 40 farmers were selected: -20 SRI farmers : 10 local variety used-farmers and 10 modern variety used-farmers -20 Non-SRI farmers: 10 local variety used-farmers and 10 modern variety used-farmers 2-Secondary data : collecting from libraries .
