Yield and conservation of onion bulbs are influenced by nitrogen (N) availability in the soil, which is required in large amounts. This study aimed to evaluate the effect of N application rates and splitting on the plant nutritional status, yield and conservation of onion bulbs after harvest. Three field experiments were carried out in Southern Brazilian Haplumbrepts. Treatments consisted of a factorial combination (4 x 3) involving four N rates (0, 50, 100, and 200 kg ha-1) and three times of sidedressing (only 45, […]
