Effects of Deficit Irrigation on Growth, Development and Yield in Cotton
Abstract：Effects of deficit irrigation on growth, development and yield in cotton under drip irrigationand border irrigation were studied in 1998～1999. It is shown that under deficit irrigation condition,drought at blooming-bolling stage influences most seriously upon the growth, development and yieldin cotton. With deficit level changing from severity to light (i. e. as the increase of water supply), thegrowth and development of cotton plants are improved obviously. Water consumption and lint yieldincrease linearly with water supply increase. Compared with border irrigation, drip irrigation is asmall quota irrigation system with more uniform water supply interval and water distribution, and cantransport directly water to plant root zone. Therefore, the growth and development of fruit branches,squares, bolls are better and leaf area index and lint yield are greater under drip irrigation than thoseunder border irrigation.
