Soybeans, often referred to as "sweet potato" in some regions, are also known locally as "raw geuca." This is an annual leguminous plant, and its underground tubers are the edible part. In recent years, yam and its roots have gained popularity due to their crisp texture, high sugar content, and rich protein levels, making them suitable for both raw consumption and cooking. As a result, the planting area has been gradually increasing.
First, soil selection plays a crucial role in cultivating this crop. Since the edible portion is the underground root, it's essential to provide a favorable growing environment. Sandy loam with good depth, moderate fertility, and well-drained soil is ideal for optimal growth.
Second, proper soil preparation and sufficient base fertilizer are necessary. After the previous harvest, deep plowing to a depth of 25–30 cm is recommended. Mix in 1,000 pounds of fire ash, 2,000 pounds of pig manure, and 500 pounds of bean cake per mu (approx. 667 square meters). Two months before sowing, break up the soil blocks and create raised beds that are 1.2–1.3 meters wide. The furrows should be about 25 cm deep to ensure good drainage.
Third, sowing should be done when temperatures are sufficiently warm, as soybean seeds require higher temperatures for germination. In Guangdong, it’s best to sow after the last frost. Plant seeds in rows spaced 20–25 cm apart, with 3–4 seeds per hole. Use 2.5 kg of seeds per acre. Before sowing, mix the seeds with ash to enhance germination.
Fourth, timely thinning and proper fertilization are essential. Once the seedlings emerge, thin them out to leave 1–2 healthy plants per hole, and finally one strong seedling. Fill in any gaps by transplanting seedlings on cloudy days, ensuring they are transplanted with their soil clumps intact. During the seedling stage, regular weeding and loosening of the soil are important. After each loosening, apply human excrement or compost to promote early growth, known as "phytoemergence fertilizer." A second dressing should be applied when the roots begin to expand in mid-June. In dry conditions, water regularly.
Fifth, pruning and staking are important for healthy vine development. When the seedlings reach about 30 cm in height, insert a bamboo pole into each hole and tie adjacent vines together to support their climb. When the vines grow over 1 meter tall, top them to prevent unnecessary nutrient consumption. Additionally, remove any lateral branches and flowers that appear along the stems to encourage leaf growth for photosynthesis. Failing to do so can negatively impact root tuber development, reducing both yield and quality.
Finally, timely harvesting is key. Four months after sowing, the tubers will have swollen enough to start harvesting, but yields at this stage are not yet optimal. For maximum yield, it's advisable to delay harvesting by more than a month. However, if harvested too late, especially before the first frost, the quality may decline, and the tubers risk freezing. The average yield can reach over 3,000 kilograms per acre.
