The Effect of the Foliar Application of Potassium, Calcium, Boron and Humic Acid on Vegetative Growth, Fruit Set, Leaf Mineral, Yield and Fruit Quality of 'Anna' Apple Trees

Effect of Sulfur and Potassium Application under Salinity Stress on Productivity and Fruit Quality of Swelling Peach Cultivar

“…According to our results, the foliar application of potassium sulphate ameliorated obviously vegetative growth, fruit set, fruit physical and chemical traits and tree production in comparison with untreated trees, these results agree with Mosa et al, (2015) on apple trees. On the other hand, raising the crop production and ameliorating the grain trait is achieved by a critical action of potassium (k) in photosynthesis operation and the consequent carbohydrate transfer and metabolism (Pettigrew, 2008 andLu, et al, 2016).…”

“…On the other hand, Nutritional status, tree bearing and traits of pear and apple trees were ameliorated by the well efficient exogenous foliar spray of potassium Gobara et al, (2001). K 2 so 4 ameliorated significantly Zn, Mn and Fe leaf contents (Mosa et al, 2015).…”

“…The increment of the TSS content and lessening the total acidity of berries were recorded by the use of higher potassium amount Martín P et al, (2004). K and N% were approved significantly by the application of potassium sulphate independently or mixed with humic acid, while P and Ca % were not altered (Mosa et al, 2015).…”

“…Considerable increments in the tree production, fruit set %, average fruit weight and declined the percentages of fruit drop were allowed by the exogenous utilization of potassium sulphate and humic acid independently or in combination between them (Mosa et al, 2015). The best tree bearing, fruit physical traits, vitamin C, and total soluble solids % were observed with Calcium chloride and zinc sulphate at 0.5, 1 and 1.5% and potassium sulphate at 1, 2 and 3% in comparison with untreated trees (Aly et al, 2015).…”

Effect of Fulvic Acid and Some Nutrient Elements on King Ruby Grapevines Growth, Yield and Chemical Properties of Berries.

“…Both are essential for many biochemical processes in plant cells as, synthesis of enzymes and protein causing an increase in chlorophyll synthesis (Dixon &Weed 1989 andNardi et al, 1996). Moreover, Matter (2003), Shoeib (2004), Rizk-Alla et al (2006), Abo Samra (2007) on Thompson seedless grapevines and Mosa et al (2015) on Anna apple trees resulted that using K or Mg fertilization significantly increased shoot length, cane thickness and leaf area in two seasons of study. A definite function of K in intensifying the synthesis of carbohydrates (Yagodin 1984).…”
