A field experiment was conducted at the Department of Agronomy, Tamil Nadu Agricultural University during the winter season of 1985 with a cotton cv. MCU 5 to study the effect of time of application of fertilizers and weed management practices on seed cotton yield. The optimum dose of N for MCU 5 cotton was 60 kg/ha. De- laying the application of N (25%) P,0, and K,0 (100%) to seedling stage (25 DAS) and subsequently top dressing of 50 per cent N at squaring and 25 per sent at flowering increased the seed cotton yield over the conventional basal application of N (50%) P,0. and K,0 (100%) and top dressing 50% at squaring. Delayed application N, P,0. and K,O reduced the cost of wasding by Rs. 142/haowing to lesser weed growth. The above findings are also suited to the areas where cotton is dibbled in rice and ragi stub- bles.
