Proper care should be taken while selecting seedlings for transplanting. Over and under aged seedlings should be avoided for better establishment. At the time of transplanting, one third of the seedling top should be cut to get good establishment. The onion seedling should be transplanted after dipping roots in carbendazim solution (0.1%) for two hours to reduce the incidence of fungal diseases during the establishment. The optimum spacing is 15 cm between the rows and 10 cm between plants.
