Influence of orchards fertilization management and post-harvest storage time on...
Figueiredo, Ana Cristina; da Silva, Anabela Bernardes; Tavares, Cláudia; Pastaneira, Mafalda; Melo, Juliana; Ferro Rodrigues, Carolina“Maçã de Alcobaça” is a type of apple from the West coast of Portugal with Protected Geographical Indication (PGI). This study evaluated the influence of the orchard’s fertilization and post-harvest storage time on the quality of “Maçã de Alcobaça”, ‘Gala’ cultivar. Five orchards were studied for four years, using three fertilization treatments [Standard, twice Standard (2xStandard) and twice Standard including...
Analysis of Petiole Sap Nutrients Using Rapid and Standard Methods and Its Rela...
Mota, Mariana; Martins, M.; Sprey, Layanne; Maurício, Anabela; Rosa, Cristina; Faria, João; Martins, Miguel; Sousa, Miguel L. de; Santos, RicardoCurrently, fertilization decisions in apple orchards are based on soil and leaf analyses while the leaf material is sampled after the growing season, usually in June–July (90–110 days after full bloom). This approach is inefficient, as the information becomes available later than the growing season and is therefore only useful in supporting fertilization decisions for the next year, not the current one. To esta...
Nutrient Content with Different Fertilizer Management and Influence on Yield an...
Mota, Mariana; Martins, Maria João; Policarpo, Gonçalo; Sprey, Layanne; Pestaneira, Mafalda; Almeida, Patrícia; Maurício, Anabela; Rosa, CristinaAssessing a plant’s nutritional status and fertilizer rates and types that can optimize fruit quality and yield are critical in intensive apple orchards. The aim of this work was to identify correlations between nutrients in the different organs that allow the early diagnosis of the nutritional status and to assess the impact on the optimal nutrient content in apple leaves, as well as in the yield and quality o...
