ABSTRACT
The production of rice has barely kept pace with population growth. In planning a national program of accelerated rice production, it is essential to have a thorough knowledge of the country's water resources, both from streams and from ground sources. Although water control is a major factor determining the feasibility of increasing rice production, some attention must be given to soil and topographic conditions. Sandy soils are usually unsuitable for rice growing. Of the acid-sulfate clay soils, some can be so managed as to produce reasonably good rice yields, but many of them are so acid and have such a high acid reserve that they cannot be reclaimed economically. Low-lying flat lands with clayey soils are ideal for rice production. Rice, being a self-pollinated crop, is relatively easy to manage for pure seed production. Major rice-producing countries can fully justify a complete research program incorporating plant breeding, entomology, plant pathology, plant physiology, agronomy, agricultural engineering, and agricultural economics.
