How to grow corn to get high yield?

During the growth and development process, corn is not only affected by various natural disasters, but also easily affected by various diseases and pests. In order to obtain high yields of corn, it is crucial to master the correct planting method. So how can corn be planted to achieve high yields? Let’s take a look below.

1. Choose good varieties

If corn is to be harvested at a high yield, variety is the key. When choosing varieties, it is important to select corn varieties that have good adaptability, strong lodging resistance, disease and heat resistance, stable and super high yields based on local climatic conditions, soil characteristics and market demand. Such as Yuyu 315, Longchuang 310, Baojing 186 and other varieties.

2. Site selection

Choose a plot with deep, fertile, loose soil that can retain water and fertilizer for planting. For spring sowing, deep plowing and careful cultivation should be carried out before sowing, and combined with land preparation, 3,000 kilograms of organic fertilizer and 150 to 200 kilograms of compound fertilizer should be applied per mu. Then land preparation should be carried out to make the soil loose and create good environmental conditions for the growth of seedlings.

3. Keep a good eye on sowing

Determine the best sowing time based on local climate and temperature conditions. Spring sowing is generally carried out from late April to early May, while summer sowing is carried out in late May or early June. For spring sowing plots, before sowing, ensure that the soil moisture is good. For plots with insufficient moisture, water the plots before sowing, then prepare the land, and finally sow the seeds. For summer sowing, sow the seeds first. For plots with insufficient moisture, water the plots in time after sowing to ensure that all seedlings are planted at once and that the seedlings are even and strong.

4. Do a good job in seedling management

When the corn seedlings grow to 3 to 5 leaves, weeding should be carried out. Depending on the type and size of the weeds, you can use agents such as nicotinamide atrazine or mesotrione atrazine for control. To reduce competitive pressure on corn plants. At the same time, attention should also be paid to the prevention and control of pests such as cutworms, beet armyworms, and thrips.

5. Do a good job in the management of the big bell mouth period

The corn tassel stage is the most critical period for the growth of corn stems and leaves and the development of cobs. A large amount of water and fertilizer is required, and scientific irrigation should be carried out according to soil moisture conditions. Once drought occurs, watering should be carried out in time; at the same time, topdressing should be carried out. Generally, about 40 kilograms of urea should be applied per mu to meet the nutrient needs of plant growth and development.

6. Harvest in time

Corn should be harvested promptly after it matures. Generally, about 60 days after flowering and pollination, the bracts of the fruit cob have dried up and become soft, the mammary glands of the grains have disappeared, and a black layer has appeared at the base, indicating that they are ripe and can be harvested. Harvesting can be done mechanically or manually.

That’s it
