| ABSTRACT The usual application of high 4-14-8 NPK fertilizer rates in the potato planting furrows, independently of the soil fertility or nutritional cultivar requirements, has become a paradigm in Brazil. However, the 4-14-8 NPK formula does not always meet the crop needs, and can unbalance the availability of nutrients in the soil. The objective of this study was to evaluate the tuber yield and economic results of ‘Atlantic’ potato as affected by rates of 4-14-8 and 6-30-6 NPK formulas applied in the planting furrows. The rates of both NPK formulas were calculated to reach P2O5 rates of 210, 420, and 630 kg ha-1. At each P2O5 rate, the 6-30-6 formula resulted in less 30% N and 65% K2O in the planting furrow compared to 4-14-8 formula. A randomized... |

| ABSTRACT Camila potato, registered and protected as BRS F63, is a cultivar for the fresh market, with oval tubers of attractive appearance, having shallow eyes, yellow and smooth skin, and light yellow flesh. It presents medium specific gravity (dry matter), which allows greater culinary versatility than ‘Agata’. Cooked tubers have a firm texture and distinctive flavor, with potential for use even in gourmet kitchen, for preparing salads and other similar dishes. The vegetative growth cycle and dormancy are medium. It presents high productive potential, with high percentage of marketable tubers. It is moderately resistant to greening. Concerning physiological disorders in the tubers, ‘BRS F63’ (Camila) is similar to ‘Agata’ and ‘Asterix’ in crops of... |
