Requirements for growing sweet corn

 

The production of sweet corn is growing rapidly in Eastern Europe and culture becomes increasingly preferred by producers. Due to a variety of weather conditions below offer general requirements for the successful cultivation of sweet corn, but they should be

 

adapted to the actual conditions.

 

Weather conditions:

 

Sweet corn can be grown under different climatic conditions, but requires high temperatures during the growing season. The plant began to develop when temperatures become higher than 10-12 ° C for normal sweet corn while supersladkite hybrids need

 

soil temperatures from about 15 ° C. It is recommended sowing sweetcorn to become warm soil constantly and there is no danger of frost. Normally this is the second half of April for sweet hybrids and late April / early May supersladkite. Earlier planting can be done only under polyethylene and subsequently maize seedlings to be through seedlings. Last dates for sowing are determined depending on when the first autumn frosts fall in your area. Plants should have formed a production date before the first autumn frost.

 

Fertilization

 

Fertilization depends on soil type. In order to achieve optimum yield sweetcorn needs 10 kg of nitrogen, 4.5 kg of phosphorus, and 12 kg of potassium per hectare. Nitrogen fertilization should be distributed as follows: 1/3 to introduce sowing and the other two thirds during the growing season. It is recommended fertilization program to develop the analysis of soil reserves.

 

Planting scheme

 

The recommended scheme of planting is 70-75 cm row spacing with density 6,000 to 6,500 plants per hectare of early varieties and 5500-6000 plants per hectare for medium early and late ones. Planting depth should be 4-5 cm normal sweet and 3-4 cm

 

supersladkite varieties.

 

IMPORTANT!

 

While growing sweetcorn isolation is necessary about 200 meters for normal sweet corn and 300-400 meters to supersladkite hybrids or discrepancy flowering period of 10 to 15 days.

 

Irrigation

 

Sweet corn is a crop with high demands on irrigation (350 mm) and requires regular watering throughout the growing season. In our region sweet corn can not be grown without irrigation.

 

Depending on the conditions, needs irrigation may be sowing the collection of the cob. The lack of irrigation may lead to a number of problems - of poor germination difficult to pollination.

 

Harvest

 

Harvesting should be done when the beans are lactic ripeness. During this period the silks on the cob becomes brown and dry. 50% of the ears are ready to harvest after 20-22 days izmetlyavaneto. The books are in optimum condition for harvesting 3-4 days
