“…Increasing N ferlitizers tended ton increase N content in leaves of orange. The results are in agreement with those obtained by Nguyen, Maneepong, and Suranilpong (2016), El-Khawaga and Maklad (2013). The optimum range N content in orange leaves recommended was 23 to 27 g/kg (Quaggio, Mattos, & Bosrtto, 2010).…”

Nitrogen (N) and potassium (K) are the most important nutrients for fruit yield and quality of citrus. Farmers - growing orange is usually applied high rates of N and K fertilizers. The study was carried out during 2017 and 2018 production year on a 4-year Valencia orange. The objective of the present paper was to evaluate the effect of combination between nitrogen and potassium on fruit yield and quality of Valencia orange. The experiment was used three doses of N (0.5, 1.0, and 1.5 kg/tree) in form of urea and three doses of K (0.6, 0.9, and 1.2 kg/tree) in form of potassium chloride in all combinations. The obtained results showed that N and K concentrations in soil did not increase with increment of N and K fertilization. Increment of N and K fertilization increased N content but did not increase K content in leaves. Fruit weight, fruit diameter and peel thickness increased with increasing of N fertilization. Maximum fruit yield of Valencia orange was attained with rates of 0.5 kg N/tree combined with 0.9 kg K/tree. Juice content increased with increasing amount of N fertilization. Increment of K fertilization tend to increase total acidity in fruit juice. The highest TSS and TSS/TA were attained with rates of 0.5 kg N/tree combined with 0.9 kg K/tree.

“…On the other hand, a high rate of K application to the soil significantly decreased the leaf Mg concentration (Table 6). This result was similar to those achieved with pummelo (Nguyen et al, 2016), cabbage, celery and lettuce (Inthichack et al, 2012), orchids (Poole & Seeley, 1978), and crested wheatgrass (Robbins & Mayland, 1993). Therefore, a high rate of K fertiliser application may cause an Mg deficiency in plants.…”

This study aimed to examine the effect of the application of dolomite and kieserite on the growth and nutrient uptake of rubber tree saplings and the relationship between K:Mg ratios in soils and nutrient uptake. The experiment followed a completely randomized design with five replicates. Budded stumps of RRIM 600 rubber were planted in soil with low extractable Mg (< 0.30 cmolc kg-1). Kieserite application at a rate of 0.5 cmolc Mg kg-1 significantly promoted the greatest sapling height, stem diameter, Mg and S concentrations, and leaf chlorophyll levels. High kieserite application rates (1.0 cmolc Mg kg-1) were more likely to decrease K and N uptake significantly. Applying dolomite (0.5 cmolc Mg kg-1) also significantly increased rubber growth compared with the control treatment but the significant increases were lower than those for kieserite application. Applying K at 72, 108, and 180 mg kg-1 significantly increased leaf K concentration, but significantly decreased Mg concentrations. Therefore, rubber plantations should apply Mg at a rate of 0.5 cmolc Mg kg-1 in the form of kieserite, and a ratio of K:Mg 2:1 is suitable for promoting rubber tree growth.

“…Pomelo leaves were collected three times in May in 3 years (2019, 2020, and 2021); each leaf sample included 50 leaves. Leaf samples were picked up from the 3 rd or 4 th position of 3-5-month-old, newly flushed, and nonfruiting twig on the outer canopy [30]. After the collection, the leaves were washed twice with tap water and then washed again with distilled water.…”

Foliar application is a popular technique to supply mineral nutrients to crops. It also enhances nutrient use efficiencies, especially under limited soil fertility or restricted environmental conditions. This study aimed to evaluate the influence of foliar application of phosphorus (P) with potassium (K), magnesium (Mg), and zinc (Zn) on the nutrient uptake, yield, and fruit quality of pomelo. The experiments were conducted between 2018 and 2021 in three different sites of alluvial soils, including four treatments, namely, control (without foliar fertilization), FF1 (containing P, K, and Mg), FF2 (P, K, Mg, and Zn), and FF3 (Zn). The results indicated that the P, K, and Mg concentrations in leaves and fruits were significantly enhanced after the spraying of solutions FF1 and FF2 compared with the control and FF3. The application of FF1 and FF2 greatly improved the fruit quality, and the fruit yield response was as high as 4.0-5.0 t ha−1. Foliar Zn application (FF3) increased the Zn concentration in leaves, but there was no improvement in fruit Zn content, fruit quality, and yield compared to the control treatment. The results indicate that FF1 or FF2 could be used as a sustainable fertilizer strategy for pomelo trees because of its ability to improve the leaf and fruit nutrient concentration and enhance the fruit quality and productivity of pomelo.
