Due to the small size of rape seeds and their high germination rate, it's common for seedlings to emerge densely, leading to overcrowding, poor nutrient absorption, stunted growth, and weak plant height. These weak seedlings are not resilient, often turn pale, and may die after transplanting in Daejeon. They are also prone to lodging and result in lower yields later on. One of the main causes of these weak seedlings is over-seeding during sowing, which leads to elongated, weak growth. To prevent this, proper sowing techniques must be followed to ensure strong, healthy seedlings. First, controlling the seeding rate is crucial. The general ratio of seedbed area to field area should be around 1:5, meaning that for every mu of field, about 0.2 mu (two-tenths) of seedbed is needed. The seeding rate per mu of seedbed is typically kept at around 0.5 kg, or 100 grams of seeds per mu. In practice, the sowing rate can be adjusted depending on conditions—such as smaller seeds, early sowing, high germination rates, good land preparation, suitable soil moisture, and effective pest control. In such cases, a slightly higher seeding rate may be acceptable. However, if conditions are less favorable, the rate should be reduced. Overall, the seeding rate should not exceed 0.6 kg per mu of seedbed to avoid excessive density. Second, timing and spacing of seedlings are important. To ensure even distribution, seeds should be mixed with finely prepared soil before sowing. After the seedlings emerge, weeding and thinning should be done at the three-leaf stage to ensure even spacing and prevent leaf overlap. This helps promote uniform growth and stronger seedlings. By maintaining good management practices, farmers can develop robust seedlings that will support higher yields in the future. In addition to these measures, regular monitoring of seedling health and adjusting watering and fertilization accordingly can further improve seedling quality. It's also important to protect young plants from pests and diseases, as any stress at this stage can have long-term effects on crop performance. With careful attention and proper techniques, farmers can significantly reduce the occurrence of weak seedlings and increase overall productivity.
