Cassava (yuca) planting time and planting methods!

Cassava is native to Brazil and is now widely cultivated in tropical regions around the world. Cassava can be harvested for many years after a single planting, has strong adaptability to the environment, and produces high yields. Its tuberous roots are rich in starch and are one of the raw materials for industrial starch. Below is an introduction to cassava (yuca) planting time and planting methods!

1. Cassava planting time

Cassava is generally planted from February to April each year. Of course, the planting time may differ slightly in different regions, because cassava needs to grow in an environment above 15°C. If the temperature is below this, it will suffer frostbite or freeze to death. Therefore, after the first year's planting and harvest are completed, during the winter dormant period, it is necessary to provide insulation.

1. Seed selection and land preparation

Cassava is a product introduced from abroad. There are many regions in our country suitable for its growth, but to grow cassava well, the first step is to select good cassava varieties. When selecting seeds, we should choose ones with relatively large tubers, carefully observe whether the surface of the seed stems is damaged or rotten, then check whether the sprouts are uniform, whether they are damaged, or whether they have been bitten by insects. Finally, select suitable tubers for use as seeds. Of course, cassava can also be sown from seeds; generally the South China brand is used. When preparing the land, the soil should be worked into fine texture, then ridges should be made and furrows opened, and base fertilizer should be applied.

2. Planting methods

There are three ways to plant cassava: flat placement, slanting insertion, and straight insertion. The planting method can be chosen according to different terrain, soil, environment, and temperature. When planting, place the selected tubers or seeds at intervals of about 80cm according to the different methods, then cover with a thin layer of soil.

3. Field management

The first thing to do in field management is that if after 20 days some have not emerged, they should be replanted in time, and the seedlings should be filled in as much as possible within 10 days. Then final planting is carried out. After final planting, when new roots and leaves grow, the first weeding should be carried out. The weeding method is generally intertillage weeding. The second weeding is generally two months later. The last weeding is one month after the second weeding. This weeding should be accompanied by one fertilization to promote the growth of cassava. Cassava needs to be fertilized twice a year. The first time is about 35 days after planting, and the second time is about 100 days after planting. The fertilizers generally used are urea, potassium chloride, and nitrogen fertilizer, which can make the tuberous roots grow larger and accumulate starch.

4. Pest and disease control

Cassava generally rarely suffers from diseases. The main pests to prevent are field mice and cassava red mites. Chemical prevention is generally carried out during the growth of cassava tuberous roots to reduce losses.

5. Harvesting method

Because cassava can be harvested for many years, there is no fixed harvest time. Generally, as long as cassava keeps growing, you can dig it up in the field whenever you want to eat it. If it is for sale, you can dig a little around the cassava roots to see whether it is mature. As long as it has grown to a certain size, it can be harvested.

The above is the introduction from Tuliu.com on cassava planting time and planting methods. Cassava has been cultivated in China for more than a hundred years. It is usually divided into two major lines, one with light green branches and leaves and one with purplish red ones. Because the tuberous roots contain hydrocyanic acid toxin, they must be soaked and rinsed before they can be eaten; the former has lower toxicity.
