Fertilizer Requirement (kg/acre)

Nutrient Requirement (kg/acre)

At the of land preparation, apply well rotten FYM @42qtl/acre. Apply fertilizer dose in the form of Nitrogen @38kg (in form of Urea@84kg), Phosphorus@20kg (in form of SSP@125kg/acre) , potash@15kg (in the form of muriate of potah@25kg/acre) in soil at time of sowing.

After sowing, apply first irrigation, it will help in good germination. Depending upon soil type and climate, apply remaining irrigations at interval of 4-6 days in summer and 8-15 days interval in winter month. Overall radish required five to six irrigations.
