Effect of Irrigation System on Yield Components of Photoperiod Insensitive Rice 3 varieties

Abstract

Traditional farming using flooding, including water loss from drowning and waste water collection There are many types that can save more water and control the quality of water supply timing. Therefore, effect of the irrigation system on the growth and yield component of photoperiod insensitive rice 3 varieties, planned for 3 x 2 factorial in randomized complete block design (RCBD) between April to August 2018 at the Agricultural Demonstration Field, Faculty of Agricultural Technology and industrial Technology Phetchabun Rajabhat University on the growth of photoperiod insensitive rice 3 varieties, RD 29, Phitsanulok 2 and Pathum Thani 1, under 2 different irrigation methods by flood water after 7 days of germination by flooding at 5 - 10 centimeters throughout the season and sprinkling water 1 hours per day. There are differences in statistical significance. It was found that rice 3 varieties and interaction with statistically significant differences affect the plant height, plant per hill, grains per panicle, filled grain, unfilled grain 1,000 grain weight and yield (kg/rai). As for the irrigation methods there were statistically
significant differences to plant height, grains per panicle and yield (kg/rai).
