Manures & Fertilisers
Manures and
fertilisers both play important role in the maize cultivation.
A liberal quantity of bulky manures should be applied
in the field if available. Add 10 to 15 tonnes of well
rotted organic matter in the form of farm yard manure
or compost before sowing. The application of organic
matter to the soil ensures good tilth and improves water-holding
capacity.
Hybrids and composite
varieties of maize exhibit their full yield potential
only when supplied with adequate quantities of nutrients
of proper time. A crop of maize yielding about 14 tonnes
of dry matter (both grain and stover) takes up about
161 kg N, 34 kg P and 110 kg K per hectare. The exact
quantity of the fertiliser that has to be applied to
the soil will depend not only on the plant requirements
of individual nutrients but also on how much of them
the soil can supply. However, as a general recommendation,
one could apply 120 kg N, 60 kg P2O5
and 40 kg K2O per hectare for hybrids and
80 kg N and 30 kg P 205 and 20
kg K2O per hectare for composites.
