Mean determined parameters were: number of false stem/plant, number of leaves/false stem, number of leaves/plant, leaves height, fresh and dried leaves, and bulbs weight, percentages and grams of N, P and K in leaves and bulbs. Fresh and dried weights of both leaves and bulbs have a narrow ratio throughout the vegetative period N and K needed by onion are greater in the first periods, and P the whole period.
