摘要：

Field experiments were conducted to determine the effect of different harvest-aid defoliants, their application rates and time of application [140 and 150 days after sowing (DAS)] on yield of seed cotton (Gossypium hirsutum L.). MRC7361BGII (3171.8 kg/ha) and MRC7017BGII (3083.3 kg/ha) produced significantly higher yield as compared to F1861 (2454.9 kg/ha). Improved water and fertilizer use efficiency coupled with better Benefit: Cost (B : C) ratio for Dropp ultra 200 ml/ha at 150 DAS clearly indicated its superiority over other treatments. Dropp ultra showed potential to improve yield besides promoting crop earliness while keeping vegetative and reproductive growth in harmony.
