Abstract

                                A field experiment was conducted at the Tamil Nadu Agricultural University, Coimbatore during winter 1989, summer 1990 and summer 1991 seasons to study effect of different dates of sowing and growth regulators on seed cotton yield of the cotton variety MCU.11. The results revealed that sowing on 15th August during winter and on 15th February during suffer were found to be optimum dates for higher seed cotton yield. Application CCC at 40 ppm alternated with DAP one per cent would promote seed cotton yield with normal dates of sowing and compensate the yield losses due to delayed sowings during winter and summer seasons under irrigated conditions.

Key words : Cotton, Sowing, Dates, Growth, Regulators, Yield.
