Cotton plant growth regulator efficacy was evaluated as influenced of rainfastness interval. Various plant growth regulators were evaluated with simulated rainfall at 0.25, 0.5, 1, 2, 4, 8, and 24 h after the PGR application. Various plant heights were recorded at 0, 7, and 14 after application. Each plant was dissected by node and divided into mainstem parts (leaf and stem) and reproductive parts (leaves, stems, squares). Fresh and dry weights were recorded for all parts. Leaf area was also recorded.
