Qualidade de tubérculos de batata da cultivar 'Atlantic' afetada pela adubação fosfatada

To evaluate the influence of phosphorus (P) fertilization on the potato tuber quality of the cultivar 'Atlantic' experiments were conducted in soils with medium (36 mg dm-3) and high (70 mg dm-3) P availability. The treatments consisted of five P2O5 rates (0, 125, 250, 500, and 1,000 kg ha-1). The experiments were conducted in a randomized block design, with four replications. Only in soil with medium P availability, the phosphorus fertilization decreases protein, but increases starch content of the tubers until rate of 595 kg ha-1 P2O5. Phosphorus fertilization increases the tuber size and ma...
