Abstract—Laboratory and field experiments were conducted to study the effect of seed polymer coating with various micronutrients either alone or in combination and foliar spray on growth, yield and yield attributing characters of cotton, pigeon pea, chickpea and groundnut. In the laboratory experiment, polymer dosage @ 8ml, 6ml, 6ml and 4ml per kg of seeds in cotton pigeon pea, chickpea and groundnut, respectively recorded significantly higher germination and seedling vigour index compared to control and other treatments. In field experiment, irrespective of crops, seed coating with polymer along with micronutrients and two foliar sprays during flowering at an interval of 10 days increased the yield to the extent of 16.7% in cotton, 19.9% in pigeon pea, 16.1% in chickpea and 13.8% in groundnut over control.
