YIELD AND GROWTH OF THE BEET IN FUNCTION OF THE FERTILIZATION WITH PHOSPHORUS

Abstract

To evaluate the performance and growth of beet sugar plants, grow Early Wonder, depending on phosphorus levels. The experiment was conducted in a greenhouse on the campus of FCAV-UNESP, Jaboticabal-SP. The experimental design was completely randomized, with four replicates and six treatments, and these comprise the following phosphorus levels: 0, 50, 100, 150, 200 and 400 mg dm^-3. During the conduct of the trial was to assess the height and number of leaves, the ten days after transplanting and the end of the cycle (60 days after transplanting) were measured leaf area, the diameter of the tuberous root, the dry mass , the content and accumulation of phosphorus in the plant and content of phosphorus in the soil. The application of phosphorus increased in growth, leaf content of P and the beet. The decline indicated that the dose of 340 mg dm^-3, P provided the greatest mass tuberous root, was associated with the concentration of P in the soil, from 54,3 mg dm^-3, and with the content of P in the shoots and tuberous root of 4.7 and 2.2 g kg^-1, respectively.
