The experiment was conducted in a Factorial Randomized Block Design with fifteen treatment combinations involving GA₃ (100 and 150 ppm), CCC (650 and 1000 ppm), and three levels of pinching (no pinching, single, and double pinching at 30 and 60 DAT), replicated twice. Results indicated that GA₃ @ 150 ppm without pinching (R2P0) produced maximum plant height, while GA₃ @ 150 ppm with double pinching (R2P2) enhanced branching, plant spread, stem thickness, leaf area, and flower yield (1.09 t/ha). The study highlights that the interaction between plant growth regulators and pinching significantly influenced growth and yield traits in crossandra.
