Abstrakt: Two experiments, one in each of the 1991 and 1992 rice growing seasons, were conducted at the Sakha Agricultural Research Station in the Nile Delta to determine the effect of irrigation scheduling on grain and straw yield of transplanted rice. The drought tolerant variety ITT, showed no significant difference in yield due to irrigation interval ranging from 6 to 10 days. For the lowland variety Giza 172, one of the common varieties in Egypt, irrigation intervals should be every 6 days for approximately one month after transplanting. Irrigation intervals can then be extended to 10 days until the end of the growing season without decreasing yield. [ABSTRACT FROM AUTHOR]
