The Latest Guide to Fertilization Techniques and Methods for Yacon

Yacon is also called jicama, because it has a swollen fleshy root like a tuber. And because the root contains a large amount of water and sugar, it is now often eaten as a fruit, which has instantly raised its value. There are many issues to pay attention to when growing yacon, but fertilization is very important, it is the best way to promote fruiting, so here is a brief introduction to its fertilization methods.

1. Fertilizer Requirements

What is mainly harvested from yacon is the fleshy root, so the nutrients are mainly supplied to the root, and in addition to that, to maintain the vegetative growth of the aboveground leaves and stems. The root needs a large amount of water and fertilizer. It needs to grow in deep, fertile, moist soil, and a large amount of base fertilizer can be applied to improve the soil quality and soil structure. Plastic film mulching and transplanting can be used to extend the growing period, enhance photosynthesis, and produce nutrients. In yacon, the roots absorb nutrients to supply the branches and leaves, and the leaves produce nutrients through photosynthesis to supply root growth.

2. Fertilization Techniques

1. Fertilization

It is best to apply relatively mild pig manure, cow manure, or humus soil made from a mixture of fallen leaves, straw, and soil that has been composted and decomposed. Do not apply poultry manure, as its heat is too high and it easily burns the plants, causing poor growth.

2. Base Fertilizer

Base fertilizer is applied when preparing the land before planting, while plowing, generally applying fertilizer, and finally mixing it with the soil and then covering with about 5 cm of fine soil. This prevents root damage. Its root system is not well developed and is mainly distributed in the soil 30 cm deep, so base fertilizer should be applied at the bottom of the 30 cm depth. For better absorption, some humus soil should be placed on top of the base fertilizer, which is beneficial for absorption.

3. Seedling-promoting Fertilizer

Yacon is planted from tubers, and after planting, before roots grow, the nutrients for growth are all provided by the tuber, but the nutrients in the tuber are limited, so some dilute fertilizer water needs to be applied as a top dressing to promote growth and keep the soil moist. The concentration must be low, otherwise it easily damages the roots.

4. Fruit-strengthening Fertilizer

After the planted crop passes the seedling stage, the main task is root growth, so top dressing can be applied two to three times throughout the entire fruit growing period. The interval between each application is one to two months, and about 200 jin per mu is applied each time. After each fertilization, watering and irrigation should be done once a week. This is beneficial for fertilizer absorption.

When growing yacon, fertilization should be carried out according to its fertilizer requirements and at different stages throughout the entire growth period. The amount and timing of application should be specifically decided according to the soil conditions and growth conditions. The above content can be used for everyone's reference and understanding, and for comparison in practice.
