- 2. INTRODUCTION • • • • • • Rice is an staple food in most of the Asian country Grown in nearly all regions of the Philippines Upland rice is one of the major crops in Arakan Valley in 1980s But due to high demand of rubber cup lump, farmers shift to rubber plantation occupying areas for upland rice Oil palm, coconut and banana are also increasing adaptation in the areas The present study tries to enhance upland rice production in various agro-ecosystem existing in the area such as rubber, oil palm, coconut and banana plantation applying vermi compost
- 3. OBJECTIVES General: Enhancing uplandrice production in various agro-ecosystem Specifically: To characterize the upland rice cultivars used To describe the bio-physical factors of the various agro-ecosystem of the upland rice To find out agro-ecosystem most appropriate for certain upland rice varieties. To determine growth and yield of the upland rice as influenced by variety and various agro-ecosystem To determine the dry biomass of upland rice as input to the estimation of the carbon storage potential of upland rice field Onofre S.

- 15. Conclusion • Hinumay and dinorado upland rice varieties has the highest yield and biomass regardless of agro-ecosystem • The early maturing variety is 90 days and maluwa • Carbon storage potential of upland rice will reach to a maximum of 0.33 Mt per ha. Onofre S. Corpuz, Ph.D
- 16. Recommendations • Various agro-ecosystem can be utilized for upland rice production specially during early stage of the plantation • Hinumay and dinorado can gave a maximum yield of 5.2 to 5.7 tons respectively under oil palm plantation with vermicast, thus recommended for cultivation • Wider spacing of plantations is advisable when planning to introduce upland rice along alleys Onofre S.
