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...
Apple and Pear Model for Optimal Production and Fruit Grade in a Changing Envir...
Sousa, Miguel L.; Gonçalves, Marta; Fialho, Délia; Ramos, António; Lopes, João P.; Oliveira, Cristina M.; Melo-Abreu, J.P.Apple and pear crops are very important to the rural economy of Portugal. Despite significant improvements in productivity and quality, due to the introduction of new management techniques, model-based decision support may further increase the revenue of the growers. Available simulation models of orchard growth and production are scarce and are often highly empirical. This study presents a mechanistic model fo...
