Effect of Irrigation Application Devices on Boll Set, Cotton Yield and Fiber Quality
Abstract
Previous research concluded that water sprayed above the canopy on open flowers interrupted pollination causing
flower drop and subsequent reduction in boll set and lint yield. The effect of water delivered through three different
irrigation applicators (spray above canopy, spray below canopy and LEPA or drag socks) on boll set, lint yield and
fiber quality of irrigated cotton was evaluated. Lint yield and the average number of bolls per plant were not
affected by the type of applicator used (P<0.05, LSD). However, lint yield was 9.9% less in the spray above canopy
applicator treatment than the spray below canopy and LEPA treatments. The type of applicator used did not affect
fiber quality.
