“Major Research on Upland Rice”
By Mar B. Arcega
The International Rice Research Institute (IRRI) recently published a 255 page report entitled Major Research on Upland Rice. It summarizes the results of IRRI research on upland rice between 1962 and 1973, and agriculturist should find it a valuable reference material.
Upland rice refers to rice grown on both flat and sloping fields that are not bounded (without embankment to control the flow of water), prepared and seeded under dry conditions, and dependent on rainfall for moisture.
“Upland rice is grown on three continents, mostly by small or subsistence farmers in the poorest regions of the world,” IRRI scientists say. “Yields are generally low: from 0.5 to 1.5 tons per hectare in Asia; about 0.5 ton per hectare in Africa; and from one to four tons per hectare in Latin America.”
