Productivity of lettuce culture in the function of nitrogen fertilizer managent
The objective of this work was to evaluate the lettuce yield under the different management of nitrogen fertilization. The ammonium sulfate (NH4)2 SO4 with 950 kg ha-1 was used as a source of nitrogen. The treatments were constituted: 100% of the N incorporated in the base; 100% of N in single appli...

| description | The objective of this work was to evaluate the lettuce yield under the different management of nitrogen fertilization. The ammonium sulfate (NH4)2 SO4 with 950 kg ha-1 was used as a source of nitrogen. The treatments were constituted: 100% of the N incorporated in the base; 100% of N in single application coverage; 50% of the N incorporated in the base and 50% in cover parceled in 2 times; 25% of the N incorporated in the base and 75% in coverage, divided in 3 times; 100% of N in 3-fold parcel coverage and the control (without N application). The plants were harvested 42 days after transplanting and analyzed the variables weight of the fresh aerial part, aerial dry mass, the number of leaves and height of plant and stem diameter. It was verified that, for all evaluated characteristics, the response to nitrogen application was positive. It was concluded that the treatments 2, 3, 4 and 5 did not difference significantly from each other, and there was no decrease in productivity, the control verified the nitrogen requirement for this crop being below the averages in all variables analyzed. |
