摘要

Two years fields study during 1989 and 1990 was conducted to find out the impact of various causes of malformation and remedial measure treatments on main fibre quality characters. Expiry-dale monocrotophos (Exp. D. Mono.) and expiry-date dimethoate (Exp. D. Dim.) induced the maximum and the minimum adverse efiect on maturity coefficient, intrinsic fibre fineness and fibre strength, respectively. None of the treatments under study significantly affected 2.5% span length. Clipping followed by foliar spray of ZnSO_4 (0.5%+0.25%CaO) brought about the maximum improvement in fibre fineness, maturity coefficient, intrinsic fibre fineness and fibre strength.
