Experiments were conducted at the Tamil Nadu Agricultural University, Coimbatore during the winter seasons of 1986-87 and 1987-88 under All India Coordinated Cotton Improvement project to screen the suitable growth regulators/hormones for MCU 9 cotton. The growth regulators tested are triacontanol at 2.5, 5.0 and 7.5 ppm with and without DAP 3% chlormequat K2O, NAA with and without DAP 3%, Recine, Atonik and Cytocyme. The results revealed that foliar spray of NAA 40 ppm at 45, 60 and 75 days after sowing or spraying of triacontanol 7.5 ppm or triacontanol 5.0 ppm with or without DAP 3% increased the seed cotton yields compared to water spray (Control).
