“…However, the differences were not consistent and depended on the cultivar. Based on a cultivar 'Jonagored' and N fertilization doses (0 to 100 kg ha −1 ), increasing the nitrogen fertilization led to an increase in the N content in the leaves compared to the unfertilized treatment, the opposite was observed in the case of phosphorus in the leaves [44]. In another study with Rocha pear [45], the application of high doses of N (120 and 160 kg N ha 1 ) did not lead to an increase in N, K and P concentrations in the leaves.…”

Assessing 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 of chemical and organic fertilization. Five orchards of ‘Gala’ were fertilized with different levels of NPK over a period of four years. Macro and micronutrients of buds, flowers, 45 and 90–110 days after full bloom (DAFB) leaves and 60 DAFB and 15 days before harvest (DBH) fruits were determined. Boron was the only element for which strong correlations, 0.7 < r < 0.9, were observed between all organ pairs. The fertilization treatments did not affect the nutrient concentrations in the leaves of 90–110 DAFB other than P, Ca and Mg and did not affect the macronutrients in the fruit. In one of the five orchards, the yield increased by 26% with double fertilization compared to standard fertilization and, for the other four orchards, the impact depended on the year. Fruit size was more related to crop load than to fertilization and TSS and firmness were not affected by the type or amount of fertilizers. Replacing part of the chemical fertilizer with organic materials did not affect productivity or fruit quality.

“…Variations among the micronutrient compositions in the apple leaves of Jonagored are influenced by soil fertilization [ 41 ]. Depletion of phosphorus and potassium levels in apple leaves may be caused by a dilution effect that occurs alongside leaf development and nutrient redistribution to plant organs at the completion of the cycle [ 42 ].…”

“…Nitrogen (N) is a major nutrient for tree growth (Chapin et al, 2011). N is among the most vital elements in plant life and impact on plant development (Kowalczyk et al, 2017). Leaf N content is 10 times higher than in woody structure in some forest (Bouvet et al, 2013).…”

This study is aimed at assessing the extent of leaf nutrient resorption efficiency during senescence of three species (Khaya. senegalensis, Syzygium cumini and Pongomia glabra) in the Sudano-sahelian region of Nigeria. The species were selected from grooves of trees found within Maiduguri metropolis. Three leaf samples at different developmental stages (young, matured and senescence leaves) each were collected from the selected species. Each sample was then analysed for nutrient contents. C content ranged from 39.79% in K. senegalensis, 43.89% in S. cumini to 41.59% in P. glabra. Matured leaves of S. cumini have the highest K content with mean value of 9.08mg/kg, whereas young leaves of K. senegalensis and P. glasbra were the highest with mean values of 8.68mg/kg and 8.45mg/kg respectively. There was a significant decrease in K. content during senescence in S. cumini. Senescent leaves of K. senegalensis and P. glasbra have higher Ca content with 1.06mg/kg and 0.81mg/kg, respectively while matured leaves of S. cumini have the highest mean Ca content (0.82mg/kg). Young leaves have the highest mean values of S content in all the leaves of the three species. S declines significantly from matured to senescent in K. senegalensis. Young leaves of S. cumini and P. glabra, and senescent leaves of K. senegalensis have the highest mean values of Mg with 0.29mg/kg, 0.39mg/kg and 0.31mg/kg, respectively. Leaf P content is highest in matured leaves of K. senegalensis, S. cumini and P. glabra with mean values of 0.06mg/kg, 0.04mg/kg and 0.06mg/kg respectively and decreases during senescent. However, the decrease was only significant in P. glabra. The highest mean value for N is recorded in the young leaves of K. senegalensis with 0.04mg/kg, but it is highest in senescent leaves of S. cumini with 0.06mg/kg and P. glabra with 0.17mg/kg
