Abstract


Field experiments were conducted for three consecutive years (1973 through 1975) during July-November, to study the water management practices for lowland rice 1320, Parallelism between grain yield and sunshine hours as well as diurnal air temperature was observed. Irrigating the field to 5 cm deep whenever saturation was reached during reproductive phase and an irrigation regime of saturation to field capacity (appearence of hair line crack) during vegetative and ripening phases contributed to higher production efficiency. Continuous submergences could not bring about any additional benefit. Irrigation regime of less than saturation during reproductive phase produced lesser and shorter panicles, with reduced grain number resulting in low grain yield.
