How to grow potatoes for high yield?

Potatoes are widely grown in our country, especially in spring. Although the planting and maintenance of potatoes is relatively simple, some skills and methods are required to achieve high yields. This involves not only correct planting and fertilization, but also careful field management. Let’s learn together how to grow potatoes to achieve high yields.

1. Soil Preparation

The growth of potatoes depends on the looseness and air permeability of the soil. Therefore, before planting, you should choose suitable soil, such as sandy soil, or make the soil loose by deep plowing, and ensure that the soil is rich in organic fertilizer . Deeply plowing the soil and making it fine and level will lay the foundation for high potato yields.

2. Seed selection

When cutting potato seeds , the tail buds should be removed, leaving only the top buds as seeds. This is because the top buds produce stronger plants, while the trailing buds are relatively weaker. Using the top sprouts as seeds will help you grow stronger, more vigorous potato plants.

3. Ridge cultivation

Potatoes prefer deep, loose and breathable soil. In addition to soil conditions, ridge cultivation is also key. Ridge cultivation not only increases the thickness of the soil layer and improves soil permeability and temperature, but also prevents water accumulation due to excessive rain, and is beneficial to the extension of potato stems. Before closing the ridges, soil should be added about twice to make the ridges wider and taller to promote the growth of potatoes.

4. Reasonable fertilization

When planting potatoes, you should avoid using only nitrogen fertilizer, but instead use a reasonable combination of nitrogen, phosphorus and potassium fertilizers. The ratio of nitrogen, phosphorus and potassium required by potatoes is about 1:0.5:2.5, showing its preference for potassium. In addition to using organic fertilizer as base fertilizer, high-nitrogen and high-potassium fertilizers should be supplemented during the potato formation period to meet its growth needs.

5. Control growth and remove flower buds

When the potato plants are covering the ridges and flower buds begin to appear, measures should be taken to control their excessive growth, such as pinching the buds and tips, and using dwarfing hormone if necessary. Avoid excessive plant growth, as this will result in reduced yields or smaller potatoes . The purpose of controlling excessive growth and removing flower buds is to save nutrients and ensure full development and expansion of potatoes.

6. Foliar Fertilization to Increase Yield

In addition to applying base fertilizer and topdressing, foliar fertilization is also an important means to increase potato yield. Foliar fertilization can not only control the excessive growth of the plants, but also promote the rapid absorption of potatoes, thereby promoting the enlargement of tubers. You can use foliar fertilizers such as potassium dihydrogen phosphate and triacontanol, dilute them with water in a certain proportion and spray them on the leaves once a week for three consecutive times to significantly improve the yield and quality of potatoes.

The above are several key management points for increasing potato yields. I hope they can be helpful to everyone. If you have other questions about potato planting and management, you can also leave a message.
