Manuring
& Fertilization
The fertilizer dose depends upon the fertility
of soil and amount of organic manure applied to
the crop. For a good yield, 15-20 tonnes of well-decomposed
FYM is incorporated into the soil. Generally,
application of 120 kg N, 80 kg P2O5
and 50 kg K2O per hectare is recommended for getting
optimum yield. Half dose of N and full dose of
P and K is given at the time of planting. The
balance half of N is given as top dressing 30
days after transplanting.
For hybrid varieties, the recommended dose per
hectare is 180 kg N, 100 kg P2O5 and 60 kg K2O.
60 kg N and half of P & K are given at the
time of transplanting. Remaining quantities of
P & K and 60 kg N is top dressed 30 after
transplanting. A third dose of 60 kg N is applied
50 days after transplanting.
