Abstract
Obtaining information about the onion responses to different doses of phosphorus can contribute to optimizing the use of fertilizers and consequently make the activity more profitable with less impact on the environment. Therefore, this study aimed to evaluate the effects of different phosphorus doses on yield and quality of onion bulbs. The design of the experiment was in a randomized block design with four replications. The treatments were seven phosphorus doses 0.00; 33.75; 67.50; 101.25; 135.00 and 168.75 kg ha-1 P2O5. The application of 168.75 kg ha-1 of P2O5 provided the maximum yield commercial of bulbs, gross income, net income, rate of return and profitability rate in onion crops. However, there was no effect on the quality of the bulbs. Key words: Allium cepa L., plant nutrition, fertigation, phosphate fertilizer, pungency.
