To protect crop from soil borne disease and pests, before sowing treat seeds with Mancozeb@5gm/kg of seeds.
15-20 days before transplanting, application of 2% urea solution helps to give healthy seedlings for transplantation. Transplanting is done in the middle of April when seedlings are 6 weeks old and having 4-5 leaves on seedlings. Water seedling beds 24hours before transplanting so that seedlings can be easily uprooted and remain turgid at transplanting time.
Fertilizer Requirement (kg/acre)
|MURIATE OF POTASH
Nutrient Requirement (kg/acre)
At the time of land preparation, apply FYM i.e. farmyard manure and mix well with soil. Apply fertilizer dose in the form of Nitrogen@48kg and Potash@24kg and Phosphorus@24kg/acre in form of Urea@104kg, MOP@40kg and SSP@150kg/acre. Apply half dose of nitrogen and full dose of phosphate pentoxide applied as a basal dose, apply it at the time of transplanting. Mn@50ppm conc. and Co@100ppm conc. are applied as micronutrients. Remaining dose of Nitrogen is applied in 2 split after first and second cutting.
