Abstract

A field experiment was conducted to study the influence of potassium fertilization (K @0, K @60 and K @ 90 kg ha-1) and secondary (Magnesium) and micro nutrients (Zinc and Boron) on growth and yield parameters and yield of cotton hybrid Bt (MRC 7201 BGII) at Hyderabad, India during 2015-16 and 2016-17. The experiment was laid out in a split plot design with three main treatments and eight sub treatments and replicated thrice. Among the potassium levels, K @ 90 kg ha-1 recorded significantly higher plant height (76.86, 106.13 cm), number of seeds per boll (30.3, 30.9), seed cotton yield (1941, 2591 kg ha-1) and stalk yield (1967, 2755 kg ha-1) during 2015 and 2016. Among secondary (Magnesium) and micro nutrients (Zinc and Boron), Mg1%Zn0.5%B0.1% recorded highest plant height (74.65, 102.80 cm), dry weight (221.39, 243.54 g), number of seeds per boll (29.27, 29.87), seed cotton yield (1941, 2591 kg ha-1) and stalk yield (1967, 2755 kg ha-1) during 2015 and 2016.
