  1. 1.   SYSTEM OF RICE INTENSIFICATION: The Farmers Field School Way AGRICULTURAL TRAINING INSTITUTE Regional Training Center 7 By: MANUEL G. JAYECTIN Training Specialist II
  2. 2. Overview <ul><li>   The System of Rice Intensification Farmer’s Field School started its implementation in Region 7 last July to October 2003 </li></ul>   Implementers obtained no formal training about SRI    Implementers obtained no formal training about SRI  Funding of P51,000 was given by ATI Central Office for two SRI sites  The two batches of trainees, from Maribojoc and Antequera, Bohol, had 21 graduates 
  3. 3. Methodology <ul><li>   Establishment of a Learning Farm -- demonstrating SRI vis-à-vis farmers’ practice </li></ul>   Agro Ecosystem Analysis (AESA)    Small group sharing    Big group discussions    Group dynamics    Special topics  Evaluation  Plant growth and yield analysis
  4. 4. Results First Cropping – July-October 2003 San Roque SRI – Farmer’s Field School Maribojoc, Bohol Area: 1,000 sq. meters Variety used : PSBRC 18
  5. 7. Yield Demonstration Trial System of Rice Intensification Farmer’s Practice Yield (tons/Ha) 6.00 5.11
  6. 8. Farmer’s Observation <ul><li>SRI rice plants showed bigger and stronger stalks, and greener leaves. Farmer’s practice plants, on other hand, exhibited yellowing during the early growth stage from transplanting. </li></ul><ul><li>The production of tillers in farmer’s practice rice was slower and lesser than in the SRI trial. </li></ul><ul><li>Rice plants of SRI trial showed better growth performance in terms of plant height and tillering (Graphs 1 and 2). </li></ul><ul><li>SRI trial obtained comparatively greater yield than farmer’s practice (Table 1) </li></ul>
  7. 9. Farmer’s Analysis/Explanation SRI trial obtained better growth performance and yield as compared to the farmer’s practice because of the following: <ul><li>Equal distribution of sunlight, air and nutrients among the rice plants on account of their equal plant spacing. </li></ul>b) Wider spacing facilitates deeper penetration of sunlight into the rice plant canopy. c) Soil cracking allows more development of the roots. d) Lesser crop-weed competition because of the numerous weedings. e) Soil cracks causes accumulation of top soil.
