One acre requires 1-1.5 kg of onion seed, and the choice of drip tape depends on the variety and row spacing. Row spacing usually affects the size of the onion bulb. Onions can be grown by direct sowing, which requires intensive management, or you may decide to establish a seedbed first. As with growing other vegetables in seedbeds, proper site planning is key to producing healthy, vigorously growing seedlings.
The nursery site should be in a safe environment, near a water source and preferably close to the crop production site. The height of the nursery bed should be about 15 centimeters to facilitate drainage, the width should be 1 meter to facilitate cultivation, and the length can be determined by yourself according to the number of seeds sown.
