THE EFFECTS OF FOLIAR NUTRITION WITH InCa FERTILIZER ON THE CHEMICAL COMPOSITION OF LEAVES AND FRUITS OF SWEET CHERRY

Abstract

The aim of this study was to evaluate the effect of the foliar fertilizer InCa on the chemical composition of fruits and leaves of sweet cherry cultivar 'Burlat'. The study involved 14-year old sweet cherry trees of 'Burlat' cultivar, grafted onto 'PHL-A' rootstock and growing at 4×3 m spacing. The trees were sprayed with InCa calcium fertilizer based on CaT technology (manufacturer: Plant Impact). The fertilizer was applied three times, at a dose of 1.5 dm 3 •ha. The first foliar fertilization was performed at the beginning of the flowering period, and the next two took place at fourteen-day intervals. The fruits were analysed for nitrate content, and both fruits and leaves were considered for dry weight and macro-and micronutrient analysis. The use of InCa fertilizer improved the dry matter and calcium content and reduced potassium, magnesium and cadmium level in the leaves and fruits of sweet cherry. The fertilizer facilitated narrowing K:Ca and K:(Ca + Mg) ratioes and extending of K:Mg, and especially Ca:Mg ratio in both leaves and fruits. Foliar supplementation with the investigated preparation resulted in an increase in nitrogen and manganese content, and a drop in phosphorus, copper, nickel and lead concentration in the leaves of the studied sweet cherry cultivar.

The Effect of Methyl Anthranilate-Based Repellent on Chemical Composition and Selected Physiological Parameters of Sweet Cherry (Prunus avium L.)

“…Use of the repellent did not influence the content of dry weight, nitrates, nitrites, macro and micronutrients, or heavy metals in the leaves and fruits of the 'Burlat' cultivar (Tables 1-3). The amount of mineral components determined in the leaves and fruits remained within the values provided in the literature [42][43][44][45][46].…”

“…When methyl anthranilate undergoes biodegradation, it loses its specific odor and does not affect the sensory parameters of fruits [22]. The content of dry weight and mineral components in the leaves and fruits of sweet cherry depends on a variety of factors, including cultivar, rootstock used, fertilization, foliar feeding, and irrigation [42][43][44][45]. Use of the repellent did not influence the content of dry weight, nitrates, nitrites, macro and micronutrients, or heavy metals in the leaves and fruits of the 'Burlat' cultivar (Tables 1-3).…”

Managing Bitter Pit in ‘Honeycrisp’ Apples Grown in the Mid-Atlantic United States with Foliar-applied Calcium Chloride and Some Alternatives

“…Fertilizer products with CaT, such as InCaä (Miller Chemical) and similar experimental products reported in this article, are advertised to improve plant growth and fruit quality by reducing the negative effects of abiotic stresses, but there are few published reports about these products in the scientific literature. Sweet cherry (Prunus avium) trees treated with InCaä increased Ca concentration and dry matter in fruits and leaves relative to an untreated control; however, this experiment did not compare InCaä against CaCl 2 or other Ca products (Mikiciuk et al, 2015). In addition, there are several Agro-K (Minneapolis, MN) Ca products (i.e., Sysstem-Calä and Vigor-Calä), as well as the antitranspirant Vapor Gard Ò (Miller Chemical), which is thought to reduce transpiration rates and thus mitigate bitter pit development.…”

Effect of foliar nutrition and growth regulators on nutrient status and fruit quality of Eureka lemon (Citrus limon)

“…Similarly, Ahmed et al (2014) reported that calcium chloride at 2% alone or in combination with other nutrients increase the calcium contents in leaves of pomegranate. Gregorz et al (2015) also reported that calcium spraying proved to be an effective way to deliver calcium to the plants, as it increases its content in both the leaves and the fruits of sweet cherry. Application of potassium sulphate might have led to increase in the potassium content of peel.…”
