CARROT YIELD AND RECOVERY EFFICIENCY OF NITROGEN, PHOSPHORUS AND POTASSIUM
The objective of this work was to evaluate the carrot crop recovery efficiency of nitrogen, phosphorus and potassium from fertilizers. Two experiments were conducted in an experimental area in Rio Paranaiba - MG. The cultivar („Juliana‟) was sown during the summer period and the cultivar „Nayarit...

| description | The objective of this work was to evaluate the carrot crop recovery efficiency of nitrogen, phosphorus and potassium from fertilizers. Two experiments were conducted in an experimental area in Rio Paranaiba - MG. The cultivar („Juliana‟) was sown during the summer period and the cultivar „Nayarit‟ during the winter period. In both experiments, the treatments consisted of six fertilization combinations of N, P 2 O, K 2 O (kg ha - 1 ): fertilization without N (0 - 500 - 450), without P (100 - 0 - 450), without K (100 - 500 - 0), standard (100 - 500 - 450), higher than standard (100 - 700 - 600) and lower than standard (100 - 300 - 300). The harvest was carried out when most of the roots presented commercial standard well accepted by the consumers. The fresh and dry matter of roots and leaves were quantified, and the yield was calculated based on the fresh matter. The analysis of N, P and K contents in leaves and roots were carried out by harvest time, and the nutrients absorption and exportation were determined based on these contents and on the dry matter of roots and leaves. N, P and K omissions reduced the yield of the cultivar „Juliana‟. For the cultivar „Nayarit‟, only P omission reduced and P and K fertilizations increased the yield. The cultivar „Nayarity‟, which is more productive than „Juliana”, absorbed more quantities of N, P and K. Carrot recovery efficiency of nitrogen, phosphorus and potassium is low. |
