“…In addition, there was effect of P doses over MI, independently of form of application, which value increased from 109.5 (0 kg ha -1 of P 2 O 5 ) to a maximum value of 116.82 (17.85 kg ha -1 of P 2 O 5 ), and decreasing for higher values ( Figure 3B). These results were higher than the highest value of 68.78 obtained by Campagnol et al (2016) in mini watermelon. According to the authors, higher MI indicates sweeter fruits, a desired characteristic in watermelon.…”

Effects of doses and phosphorus application forms were studied on the postharvest quality in seedless watermelon hybrid 'Style'. For this, an experiment was conducted in Upanema/RN, Brazil, during the period of September to December 2013, in a randomized block at factorial scheme 5×2 constituting of five phosphorus doses applied in foundation (0, 76, 168, 275 and 397 kg ha -1 of P 2 O 5 ) and foundation + fertigation (0+50, 26+50, 118+50, 225+50, 347+50 kg ha -1 of P 2 O 5 ) with four replications. Fruit harvested at commercial maturity (78 days after sowing) were evaluated by average fruit weight (AFW), pulp firmness (PF), chroma index, hue angle, soluble solids content (SS), titratable acidity (TA), maturation index (MI), total phenols content (TP), vitamin C (VC), total sugars content (TS), reducing sugars content (RS) and pH. Among the quality parameters evaluated phosphorus application forms did not affect physical characteristics of fruit, but combination of application via foundation + fertigation increased VC, TS and MI. There was interactive effect of dose and phosphorus application form for the SS, TA, pH and TP. The dose of 50 kg P 2 O 5 ha -1 applied only in fertigation significantly increased values of SS, TA and TP. It is concluded that low doses of P in cultivation and its application via foundation and fertigation improved the main quality characteristics of 'Style' watermelon.

“…Soluble solids and maturity index (Table 3) exhibited no differences for either of the factors assessed. Unlike in the present study, Campagnol et al (2016) found that the number of stems influenced soluble solids, whereby single-stemmed systems showed higher concentrations than their two-stemmed counterparts, with average values of 11 ºBrix. In regard to the maturity index, the management practices adopted here did not influence the fruit flavor.…”

Watermelon farming has a high economic and social importance. In parallel, the consumers’ demand for distinctive products has led to niche markets, where mini watermelons stand out. This study aimed to assess the agronomic performance and fruit quality of mini watermelon grown in coconut husk fiber, as a function of number of stems per plant and plant density. The Smile hybrid was used, as well as a randomized block design, in a 2 x 2 factorial scheme, with eight repetitions, being the first factor the number of stems per plant (1 or 2) and the second the number of plants per pot (1 or 2). Characteristics related to yield, physiological parameters and fruit quality were assessed. Interaction between number of stems and plant density was only observed for leaf area, average fruit fresh weight, total yield and percentage of large fruits. The factors were evaluated separately for the remaining traits. Two-stemmed training systems, at a density of one plant per pot, produce the highest yield, without compromising the quality of the fruits, being, in these conditions, the most suitable method for farmers.

“…The results found in this study suggested that fruits formed on basal nodes are smaller, in mass, in comparison to fruits formed in distal nodes. Moreover, an increase in density may reduce interception of solar radiation by the leaves of the lower portion of the plant, which results in a decrease in their photosynthetic efficiency, it means, the amount of photoassimilates directed to the fruits (Campagnol et al, 2016).…”

Brazilian watermelon productivity is not efficient when compared to the largest producer countries, due to abiotic and biotic factors. Some of the difficulties are because of a small number of studies on this crop in Brazil. The aim of this study was to evaluate the effects of plant density and fruit thinning on two commercial watermelon hybrids (Talisman and Youlie), using trials which were carried out in two different seasons (April - July and August - November). The experiment was conducted in Uberlândia-MG and consisted of two managements of fruit position (A-basal and B-distal) and four plant densities (3,000, 4,000, 5,000 and 6,000 plants/ha). In season 1, the distal management was the most productive in relation to all cultivation densities. The distal management shows higher productivity in both hybrids, with greater increase in mass, productivity and 0Brix content in hybrid Talisman, however with lower density, firmness and internal cavity compared to hybrid Youlie. Weather conditions determined the influence of fruit management on watermelon crop. Cultivation during the hottest period and with a better water supply (season 2), basal management (A) showed a performance similar to the distal management. At this time, hybrid Talisman surpassed hybrid Youlie concerning productivity, average mass, fruit density, firmness and internal cavity. In both seasons, higher densities are related to higher productivities. Hybrid Talisman showed higher productivity in cultivation from April to July (season 1) under distal fruit management.
