Resumo: | Snap beans (Phaseolus vulgaris L.) belong to the same species as common beans and require similar management practices. Studies aimed at nitrogen fertilization in pod beans are scarce, but necessary, considering the demand from farmers for greater productivity of these beans. The objective of this study was to evaluate the effects of nitrogen fertilization in various doses and times of application on the snap beans production. The experimental design was completely randomized in a factorial scheme (2×7) + 1, represented by two doses of nitrogen (30 and 60 kg ha-1) and seven fertilization strategies (100% of the dose provided at sowing or phenological stages V3, V4, or R6; split, with 50% at sowing and 50% at V3, 50% at sowing and 50% at V4, or 50% at sowing and 50% at R6), plus a control (no added N). We analyzed stem length, stem basal diameter, number of trefoils, number and mass of commercially viable pods, and number and mass of total pods. Nitrogen fertilization with 30 kg ha-1 N divided 50% at sowing and 50% at V4 or 50% at sowing and 50% at R6 yielded larger and more numerous pods from plants with greater stem diameters. |

Snap beans (Phaseolus vulgaris L.) belong to the same species as common beans and require similar management practices. Studies aimed at nitrogen fertilization in pod beans are scarce, but necessary, considering the demand from farmers for greater productivity of these beans.

We analyzed stem length, stem basal diameter, number of trefoils, number and mass of commercially viable pods, and number and mass of total pods. Nitrogen fertilization with 30 kg ha-1 N divided 50% at sowing and 50% at V4 or 50% at sowing and 50% at R6 yielded larger and more numerous pods from plants with greater stem diameters. |
