Produtividade de alho vernalizado em função de fontes e doses de fósforo

Abstract

The objective of this research was to verify the influence of sources and doses of phosphorus in the productivity of vernalized garlic in soil with low phosphorus content. The experiment was carried out in field conditions in the Horticulture Sector at the Universidade Federal de Lavras. Three sources (simple superphosphate, with 18% of P2O5; triple superphosphate, with 41% of P2O5 and magnesium term phosphate, with 17% of P2O5), three doses (200, 400 e 600kg ha-1 de P2O5), and one additional treatment, that didn't receive manuring with phosphorus were tested. The application of 200kg ha-1 of P2O5, using triple superphosphate provides the best profit in total mass of plants and productivity of commercial bulbs.
