Abstract: A field experiment was conducted at the Instrucional Farm, College of Agriculture, Junagadh Agricultural University, Junagadh on "Effect of cultvars and potassium levels on content and uptake of nutrients, yield and and quality of Bt. Cotton". The experiment consisting of 15 treatment combinations with five Bt cotton cultivars viz., Ankur-165, Vikram-5, Shakti-7, Rashi-2 and Mico-162 and three levels of K2O(0, 80 and 120 kg ha-1). The results revealed that the cultivar V4(Rashi-2) recorded significantly the highest dry matter yield, lint yield, seed cotton yield, total cotton yield, higher balls per plant, ball weight, as well as the higher value of micronair, stepple length and 2.5% span length. The application of potash @ 120 kg ha-1 gave significantly higher dry matter, lint yield, seed cotton yield, stalk yield and total cotton yield. The quality parameters viz., micronair, stepple length, span length, oil content and ginning percentage were also recorded higher with cultivar Vikram-5. The concentration and uptake of K were recorded higher with dry matter, stalk and seed cotton were recorded higher under application of K2O @ 120 kg ha-1. Similarly, the application of K2O @ 120 kg ha-1 registered significantly higher uptake of N, P and K by seed cotton.
