The field experiment was conducted at Main Agricultural Research Station, Raichur on medium black soil during kharif, 2017 to study response of cotton (Gossypium hirsutum L.) varieties to varied sowing dates and nutrient levels. Among the varieties, BGDS-1063 produced significantly higher plant height and dry matter production per plant (126.62 cm and 288.22 g plant-1) over SCS-793. Significantly higher plant height and dry matter production was noticed in case of cotton crop sown on 1st fortnight of July (128.14 cm and 292.60 g plant-1) as compared with cotton sown on 2nd fortnight of July and similarly application of 150 per cent of recommended dose of fertilizer (RDF) noticed significantly higher plant height and dry matter production (129.33 cm and 294.80 g plant-1) over 100 percent RDF. Similarly higher uptake of nutrients like Nitrogen, Phosphorous and Potassium was recorded significantly higher in BGDS-1063 (96.90 kgha-1, 21.65 kgha-1 and 128.59 kg ha-1) as compared with SCS-793. Among sowing dates early sown crop, crop sown on 1st fortnight of July noticed significantly higher uptake nutrient like nitrogen, phosphorous and potassium (98.01 kg ha-1, 21.80 kg ha-1 and 129.53 kg ha-1) compared with crop sown on 2nd fortnight of July and finally among application of 150 per cent recommended dose of fertilizer (RDF) registered significantly higher uptake nutrients like Nitrogen, Phosphorous and Potassium (97.14 kg ha-1, 20.70 kg ha-1 and 122.95 kg ha-1) over 100 percent RDF.
