Responsive Cotton to PGR Treatment Under Differing Drip Irrigation Regimes

A study was conducted at the Texas Agrilife Research Farm, near College Station, Texas, to interface sub-surface drip irrigation and plant growth regulator (PGR) use. Treatments consisted of two PGRs (Stance “2.5oz/A and Pentia” 16oz/A) and an untreated control across three irrigation strategies (Full, 26 acre inches: Partial, 18.6 acre inches: Rain-fed 7.5 acre inches of rainfall). Plots were evaluated on certain plant measurements, yield, and fiber quality. Significant differences occurred among plant measurements, fiber quality, and yield.
