Abstract

Major climatic factors are discussed in relation to their influence on crop period, productivity, and stability. Most places in monsoonal Asia receive about 300 cal/cmz per day during the ripening period of the wet season rice crop. With the right variety and proper management this level of solar radiation should allow rice crops to produce 4 to 5 t/ha. Advantages and disadvantages of altering plant height and growth duration are described. Intermediate plant height has certain recognized benefits when water control is undependable but these benefits may not be realized unless the varieties resist lodging. Early maturing varieties will become increasingly important. For direct-seeded rice, the shortest growth duration, without much sacrifice in yield potential, is about 90 days; for transplanted rice, it is about 100 days
