MAIZE

Types of Maize. Several thousand varieties of maize are now grown throughout the world and most of these can be allocated to one of the seven most important groups: dent maize, flint maize, sweet corn, soft maize, popcorn, waxy maize, pod maize.

Soil Requirements . Successful maize cultivation is more frequently and more easily achieved on soils which are of me­dium texture.

The maize land should be free draining in order that as much of the heat as possible is employed in raising soil tem­peratures and not removing excess of soil moisture. The soil should be naturally free draining to enable a full rooting system to develop in a plentiful supply of oxygen.

Cultivation. Maize will require deeper plough­ing, cultivations and seed-beds to obtain maximum growth. Autumn ploughing is advisable on stronger soils and it may be left until the early spring when textures are light. Culti­vations which follow should be to a depth of 4-5 inches. They kill the weeds after germination; inter-row cultivation can follow crop emergence to obtain further weed control.

Sunshine and Solar Energy. Little is said and written about sunshine and solar energy requirements with this ce­real. It is, however, assumed that for satisfactory growth and ripening of the crop high levels of bright sunshine are re­quired.

Maize is quite unique in its mode of growth and extent and duration of its leaves. They grow in a manner which facilitates efficient use of radiant energy by trapping most of the sun's rays and since the duration of full leaf extends al­most to grain maturity, the sun's energy can be transferred to grain yield throughout the whole life of the plant. A point close to optimum leaf area is obtained early and maintained almost to grain maturity thus making maize one of the most efficient utilizers and converters of solar energy into plant energy particularly when the whole plant is considered as the economic yield.
