What are the precautions for growing cassava? A detailed explanation of the latest key points
Cassava is cultivated all over the world, and China has a history of cultivation for over a hundred years. Its tuberous roots are rich in starch and are one of the raw materials for industrial starch, with relatively high economic returns. So what should be noted when planting it? Let's take a look.
1. Deep plowing to improve the soil
One month before planting, the land must first be prepared by covering the soil to a depth of 30-40 cm, using sunlight to bleach it white so it fully weathers and loosens. This is because cassava is a deep-rooted crop, and its roots extend widely downward. If the soil is too sticky and heavy, it may cause poor or deformed root growth, which is unfavorable for both yield and quality. Therefore, before planting, the land must be prepared and the soil loosened, which helps increase its yield. In addition, when planting, 250-300 kg of decomposed farmyard manure can be applied per mu as a base fertilizer.

To obtain high yields, in addition to suitable soil, you should also choose good varieties with high tuber formation and high yield. In addition, cassava contains hydrocyanic acid toxin, so try to choose varieties with lower toxicity. Select tubers with thick, dense stem nodes, free of pests and diseases, and without damage as seed stems, and treat the seed stems before planting.
3. Fertilization
To obtain high yields, fertilization is an extremely important factor. After sowing and emergence, when the seedlings grow to 12-15 cm, topdressing should be carried out in time, preferably with dilute manure water, to promote seedling growth. In addition to fertilizing the seedling roots, fertilizer should also be applied around the seedling roots to promote more rooting and accelerate root extension. When the seedlings grow to 50 cm, apply the second topdressing. At this time, in addition to manure water, 8-10 kg of urea should also be applied per mu, preferably watered on. After autumn begins, expose the tuberous roots and sun the soil for 4-5 hours, then apply phosphorus and potassium fertilizer and earth up the soil.
