For uniform flowering, the source lists growth-regulator solutions poured into the crown at the 35–40 leaf stage, and an NAA spray after fruit set for bigger fruits — use these only with officer guidance. Give adequate shade to avoid iron chlorosis. Mulching with black polythene followed by thatch grass or sawdust improves yield and quality and suppresses weeds.
Follow the instructions on the product label. Consult your local Agriculture Officer before use.
