“…Rangel et al (2018) verified a linear increase in soluble solids in melon fruits with increased K concentration in the irrigation solution. When combining fertilization between K and calcium, Bouzo, Céccoli, and Muñoz (2018) also verified positive linear effect on soluble solids content with increase of these nutrients in the soil.…”

“…This increase in the concentration of sugars in the fruit may be associated with the role that K plays in apoplastic co-transport during the sucrose loading between the mesophyll and the phloem (WHITE; KARLEY, 2010). The literature is rich in approaches that confirm the positive effect of an increase of K on TSS in this crop, as found in Lin, Huang and Wang ( 2004), Demiral and Köseoglu (2005), Bouzo, Céccoli, and Muñoz (2018), Yang et al (2019) and Oliveira et al (2021). Thus, maintaining an adequate supply of K for melon plants ensures a better quality of the fruits, with regard to the degree Brix.…”

The objective of this study was to evaluate the assimilated contents of mineral elements, yield characteristics and fruit quality of ‘Goldex’ yellow melon fertigated with different doses of nitrogen (N) and potassium (K) in two years of cultivation in the region of Apodi Plateau-CE. The design was randomized blocks in a 4x3 factorial scheme with four N doses (0%, 50%, 100%, 150% of the recommended dose) and three K doses (0%, 100%, 150% of the recommended dose). In the shoots of the melon plant, the highest levels of N (N Fert.) and K (K Fert.) fertilization promoted an increase in the assimilated N content up to 48 DAT and a reduction in the assimilated K content at the end of the cycle (62 DAT). The maximum shoot dry mass production was 3.23 t ha−1 with a fertilization of 150 and 100 kg ha−1 of N and K, respectively. The average marketable fruit yield obtained in the two years of cultivation was 34.68 t ha−1, reaching a maximum value of 40.28 t ha−1 under 150 kg ha−1 N and K fertilization. Total soluble solids increased as a function of the increase in N Fert. and K Fert., with a maximum value of 8.07 °Brix. The models indicated that the K Fert. factor was decisive in the increase of this variable. In future studies it is necessary to increase the concentrations of the two factors in order to optimize the maximum viability of yield and °Brix.

“…It can be assumed that the accumulation of melon metabolites is genetically determined but also strongly influenced by weather conditions. In addition, Bouzo et al [54] found different plant responses in two melon cultivars to potassium and calcium fertilization, suggesting that the chemical composition of melon fruit is also subject to environmental variability.…”

Melon (Cucumis melo L.) Fruit Yield under Irrigation and Mycorrhiza Conditions

2023

View full text Add to dashboard Cite

The size and quality of the melon fruit yield depend on the cultivar, climatic and agronomic factors. A three-year field experiment investigated the effect of arbuscular mycorrhizal fungi (AMF) application and irrigation (IR) on the fruit yield of melon (Cucumis melo L. var. saccharinus Naud.) cultivars. The study was conducted on a certified organic farm located in south-eastern Poland (51.36° N, 22.83° E). The factors of the experiment were as follows: cultivar (Melba, Emir F1, Seledyn F1, Oliwin) and cultivation method (AMF and IR; AMF and non-IR; non-AMF and IR; non-AMF and non-IR as control). The dry matter (%), soluble solid (%), total sugar and reducing sugar (% fresh weight, FM), L-ascorbic acid (mg · 100 g−1 FM), and carotenoid (mg · 100 g−1 FM) contents of the fruit were determined. The highest total and marketable fruit yields were obtained using AMF and IR. Fruit from the AMF series (IR and non-IR) had the most carotenoids (respectively: 801.5 and 788.8 µg · 100 g−1 FM). The fruits of the AMF and IR plants contained the most total sugars (5.98%) and reducing sugars (2.91%) compared to the others. The control plants had the lowest number of marketable fruit, total and marketable fruit yield, and accumulated the least L-ascorbic acid, total sugars and reducing sugars. We suggest that AMF and IR can be recommended as a practical agronomic solutions for the field cultivation of melon under temperate climate conditions.

“…Calcium is responsible for proper plant cell division and for strengthening cell walls [40,41]. This nutrient has beneficial effects on fruit firmness and alleviating influence on physiological as well as pathogenic disorders in fruit [42][43][44]. Sulfur is essential to metabolism of amino acids [45] and interacts with N in protein synthesis and accumulation [46,47].…”

Towards Balanced Fertilizer Management in South China: Enhancing Wax Gourd (Benincasa hispida) Yield and Produce Quality

et al. 2022

Balanced fertilizer management promotes plant growth, enhances produce quality, minimizes inputs, and reduces negative environmental impacts. Wax gourd (Benincasa hispida) is an important vegetable crop species in China and in South Asia. Two crop nutrition options, NPK and the natural mineral polyhalite, were tested, separately and combined, with the aim of enhancing wax gourd yield and quality and simultaneously to increase nutrient use efficiency and reducing inputs. The experiments tested the optimization of NPK by reducing the proportion of phosphorus (P), and the effect of enriching the soil with essential macronutrients by the use of the supplementary mineral fertilizer polyhalite containing magnesium (Mg), calcium (Ca) and sulfur (S). Two experiments were carried out in Foshan County, Guangdong, China, in 2018 and 2019. Experiments included four treatments: (1) Conventional NPK (15:15:15); (2) Optimized NPK (16:8:18); (3) Conventional NPK + polyhalite; (4) Optimized NPK + polyhalite. Fertilizers were applied prior to planting. While optimized NPK alone had no effects on fruit yield and quality, supplementary polyhalite resulted in a 10–17% increase in yield and significantly improved produce quality due to increased nutrient uptake from polyhalite, resulting in better foliar biomass. We conclude that the combined crop nutrition options improved yield and quality, enhanced nutrient use efficiency, and reduced risks of nutrient pollution. Inclusion of polyhalite in balanced fertilization practices as a supplementary source of secondary macronutrients seems promising. Nevertheless, plenty of space remains open for further adjustments of NPK application management, focusing on reduced rates, optimized ratio, and accurate timing of application for each nutrient.
