Guide people on techniques to grow high-yield corn

In our country, so far, maize is considered as a short-term food crop of importance second only to rice. Not only as an ingredient for many dishes, a popular daily food, corn is also a pet food. More specifically, this plant is not picky about soil, is easy to adapt, grows well, so it is grown in almost every locality. However, in order to have a bountiful harvest and earn more profits, we invite you to pocket your pocket corn farming techniques high yield below.

  1. Cultivation of land to grow corn

Although corn is not a plant that is too picky about soil, people should still cultivate the soil before planting to achieve the best yield. The cultivation steps take place according to the following principles:

  • Clean weeds on the surface
  • Plow the soil 15-20cm deep to ensure porosity
  • Drying with lime for 1 week to 10 days to completely treat pathogens and harmful microorganisms in the soil
  • Next, fertilize with organic fertilizer, which can be decayed manure with an appropriate ratio to provide nutrients to the soil.

Particularly in localities where people often grow rice, they can plant corn as soon as the rice is harvested, the soil is still wet without cultivating the land.

Corn can be grown all year round, but for the convenience of watering, people should plant it at the end of the dry season, at the beginning of the rainy season.

  1. Choosing varieties, planting corn

If in the past, we used to know only two types of corn, yellow corn for chickens and sticky corn to eat, now there are many new varieties. In recent years, people have been popularizing American sweet corn or hybrid purple corn, which has a more special flavor. Depending on business purposes or family preferences, you should choose the right breed.

Corn is grown by seeding, so to increase the germination rate, you need to conduct seed treatment before entering the hole:

  • Buy qualified seeds from reputable stores
  • Disinfect seeds with Captan or Dithane at a concentration of 2-3% to prevent fungal diseases and also prevent insects from eating seeds
  • Can be sown dry or soaked, seed incubation depends on each grower

The treated seeds will be planted directly on previously cultivated land, the process is as follows:

  • Use your hands or tools to dig holes in the soil to sow seeds, sow about 2-3 seeds in each hole
  • Corn planting distance: 20-40 cm from the plant, 60-10 cm between rows to ensure the most appropriate light and nutrient conditions, to support plant growth.
  • Planting too sparsely reduces yield, planting too thick reduces pollination quality, corn kernels are often flat, susceptible to pests and diseases.
  • Can be intercropped with other short-term agricultural crops such as legumes to improve economic efficiency
  • After planting should be watered immediately, should use more straw or leaves to cover the surface of the holes to keep moisture, to help seeds germinate quickly.

  1. High yielding corn care techniques


Maize is drought tolerant but lack of water can also reduce yield, stunted plants, small corn, not full of seeds. So, if you plant in the dry season, you should still water every 7-10 days, don’t water too much, it will cause waterlogging.

In the rainy season, you should apply the method of clearing to create a drainage system to limit waterlogging that can cause uprooting, falling or root rot.

Besides, after 4-6 days of sowing, the plant begins to produce 1-2 true leaves, then proceed to prune miles, remove the places where the tree is dead or the seeds do not germinate. Pay attention to clean weeds periodically, both to prevent the plant from losing nutrients and to prevent pathogens.


In addition to priming, farmers should fertilize crops to increase the yield of corn in each crop. Usually, the last fertilization should only use urea and potassium, applied twice during the growing, leafing and pre-pollination stages to increase the quality of corn.

In addition, farmers need to actively prevent pests and diseases for maize by regularly monitoring to detect and intervene in time if there are pests. Some common diseases in maize are aphids, stem borers and fruit borers.


After a period of about 60-65 days, if properly cared for, corn will be harvested with high yield, evenly distributed, large and grainy.

In short, the technique of growing corn is not too complicated, but people should still pay attention to the right care to get the highest yield and quality. Let’s immediately apply the experiences that we have just guided in the next corn season!
