“…One study [31] revealed that all used treatments, including foliar application with potassium citrate, were effective in increasing the yield of 'Canino' apricot trees when compared with control. Furthermore, [32] indicated that the foliar application of potassium nitrate and potassium sulphate significantly enhanced the yield of 'Jaffa' sweet oranges over the control (water spray). Moreover, the fruit yield of plum trees was improved by foliar application of potassium nitrate as compared to the control [33].…”

This is the first report to study the impacts of potassium sources on apricot fruit yield, quality and storability as a preharvest foliar application. Five sources of potassium (K-humate, K-sulphate, K-nitrate, K-silicate and K-citrate), plus water as a control treatment, were applied individually at 0.2% three times on ‘Canino’ apricot over the 2019 and 2020 seasons. The results showed that all potassium salts, applied foliarly, have potential to improve yield, fruit color, and some fruit physical attributes, such as: weight, size and firmness, as well as a reduced lipid peroxidation, accompanied by a low fruit malondialdehyde content reflected in a high tolerance during storage. The K-nitrate treatment was more effective in the improvement of fruit yield, preharvest quality parameters and keeping fruit postharvest quality characteristics from sharp decline during cold storage. Concerning fruit anatomy, K-nitrate and K-citrate showed thicker cuticle and epidermal parenchyma cell diameters, while the K-silicate induced the highest cell wall thickness. K-nitrate was the most economical, and could be recommended for apricot growers in the Nubaria region of Egypt.

“…Also, it was found that average fruit weight, fruit diameter, medium and large fruits%, and tree bearing of sweet orange cv. Jaffa was enhanced significantly above untreated trees when treated with Potassium sulphate at 1.5 and 3.0 % (Vijay et al ., 2017). Taha et al ., (2014) noted that high increment in the bear tree, fruit set %, average fruit weight and diminished of proportions of fruit drop are committed by the exogenous foliar spray of potassium sulphate and humic acid independently or by mixing the two materials.…”

This study was conducted during two successive seasons (2016 and 2017) at El-Sheikh Zwayed, North Sinai Governorate, Egypt. The aim of this research was to investigate the effect of three anti-salt stress materials (Nile fertile, elemental sulfur and potassium sulfate) on Swelling peach cultivar under irrigation water saline stress. In this experiment Nile fertile was applied at (0, 500 and 1000 gm/ tree), elemental sulfur (95% S) as soil application at three levels (0, 500 and 750 g / tree) and potassium sulphate as foliar application on three concentrations (0, 2, and 4 g/l.) and combination of them. The obtained results revealed that all anti-salt stress substances have a positive effect on vegetative growth parameters, fruit set, and yield/tree. The highest significant value of the final fruit set, yield/tree was obtained with Nile fertile treatment followed by elemental sulfur and potassium sulphate in both seasons of this study. On the other hand, there was no significant differences between the three materials on fruit length, fruit diameter, flesh and pit fruit weight, total soluble solids, total acidity and leaf content of N%, P% and k% during both seasons of the study and leaf content of Fe (ppm) in the 1 st season. While the interaction effect between the three investigated factors shows clearly significant effects in improving vegetative growth, final fruit set no. of fruits /tree, fruit weight, crop yield, fruit physical and chemical parameters. Thus, the combination between Nile fertile 1000g/tree + elemental sulfur 750g/tree + potassium sulphate at (4g/L) gave the best results on shoot length, leaf area, initial, final fruit set %, fruit length and diameter, flesh weight (g), pit weight (g), maximum yield/tree, TSS, lowest acidity%. In addition to N, P, K, Fe, Zn and Mn in leaves in both seasons. On the other hand, untreated trees recorded the lowest values in previous studied parameters in this respect.

“…Our results may gain support from those obtained by Arquero et al (2006), Sarrwy et al (2010), Hussein (2008), Abdel-Nasser and EL-Shazly (2001), Amnon et al (2018/2019) on olive trees. Moreover, (Vijay et al, 2017) found that foliar application of potassium nitrate and potassium sulphate significantly enhanced the yield of 'Jaffa' sweet oranges and potassium nitrate improved fruit yield of plum trees (Jawandha et al, 2017). On 'Canino' apricot trees, the yield was increased significantly with the application of potassium citrate (Haggag et al, 2016) and application of potassium nitrate and potassium citrate (Okba et al, 2021).…”

“…Mineral nutrition is one of the main tools for improving fruit yield and quality ( Tagliavini and Marangoni, 2002). It is well known that spraying fruit trees with nutrients improved vegetative growth, flowering and correction of deficiency symptoms reflects on the quality of the fruits (Josan et al, 1995 andDalal et al, 2017).…”

Picual olive trees grown in a private orchard located 182 kilometers south of Cairo on the Western Desert Road in Minia Governorate, and aimed to investigate the effect of foliar sprays with different potassium sources on growth, leaf mineral composition, yield and fruit quality. Foliar application potassium sources such as; potassium sulfate, potassium nitrate, potassium citrate and monopotassium phosphate were applied at 1.5 % and 3 % . Spraying is carried out three times immediately after the final fruit set (May), after hardening of the pit (first week of August) and after harvesting (October). The results showed that using the studied foliar potassium sources significantly improved vegetative growth, leaf mineral composition, fruit set, yield and fruit quality of Picual olive trees in comparison with control trees. Spraying of potassium nitrate at 3 % achieved the best results in terms of vegetative growth (shoot length -number of new laterals / shoot -number of leaves -leaf area) followed by spraying with potassium citrate at 3% in both seasons. As for leaf mineral content, nitrogen and potassium percentages were increased as a result of foliar application with potassium nitrate at 3 %. Picual olive trees were sprayed with potassium nitrate and potassium citrate at 3 % had the highest values in the flowering characteristics. Yield and fruit quality were significantly affected and the highest values were achieved in Picual olive trees sprayed with potassium nitrate at 3% followed by potassium citrate at 3% in both seasons.
