How to Grow Onions for High Yield? Save This Planting Secret Recipe

Prepare a piece of land with ample fertility, deep plow it and apply sufficient base fertilizer. Then select some healthy, high-quality seeds, soak them in cool water for 12 hours, remove and drain them, and place them in a 25°C environment to germinate. Once germinated, sow them into the soil at a row spacing and plant spacing of 10*10cm. When the seedlings grow until October, transplant them into the field, and finally carry out basic management tasks such as watering, fertilizing and earthing up, and you can achieve high yield.

Key Points for High-Yield Onion Cultivation:

1. Seed selection

First, we need to understand the local onion cultivation situation, see how the varieties they choose perform and whether the yield is high. Second, analyze the market to see whether growing this variety of onion is competitive. After choosing the variety to grow, the next step is to select high-quality seeds from it. We mainly do this by observing whether the seed color is bright, whether the seeds are plump, and whether there are pests or diseases. If none of these problems exist, then it is fine.

2. Timing

Whether the onion planting time is chosen correctly has a huge impact on onion yield, so you must pay close attention when choosing the planting time. Although onions can be planted all year round, if you want the onions you grow to be high-yield and high-quality, it is best to choose to plant in August and September. At this time, the temperature in most areas is generally around 20 to 25°C, which is most suitable for onion germination and growth.

3. Watering

Before sowing, we must first water the land once to ensure soil moisture. Next, when the onions grow three leaves, they need to be watered. Onions need a certain amount of moisture during their growing period and cannot be too dry, otherwise the onions below will not grow large, and the onions that do grow will have no moisture. Usually we water once every week, but note that in winter you must never water, otherwise the onions will rot.

4. Fertilizing

Fertilizing is a very important part of onion cultivation, so special attention is needed. If the wrong fertilizer is used or the wrong amount is used, it will cause irreparable losses to onion growth. When conditions allow, it is best to mainly use farmyard manure or organic compost, supplemented with an appropriate amount of chemical fertilizer. On average, one mu needs about two thousand jin of fertilizer, of which the amount of chemical fertilizer is about three hundred jin. Next, onions need sufficient nutrients during their growing period, so we should apply additional fertilizer in appropriate amounts according to the growth condition of the onions, and at the same time choose what kind of fertilizer to apply based on the specific situation.

5. Pest and disease prevention

The most common pests and diseases of onions are downy mildew, damping-off, and onion maggot. The control methods for downy mildew and damping-off are generally spraying with chlorothalonil or Bordeaux mixture, while for onion maggot we can water the field, because onion maggot is very afraid of water and will flee or even drown. Finally, trichlorfon crystals can also be used for control.
