“…Cultivation costs of papaya in greenhouses of SE Spain for a 26-month growing cycle are estimated around 0.60 EUR kg −1 , which, although still high, is lower than that for vegetable production considering the higher water consumption for papaya but a much lower expenditure on phytosanitary than in other horticultural crops [18]. These calculations of the production costs in protected cultivation include labor force (mostly for cultivation and harvest); inputs for irrigation, fertilization, pest and disease control, and the indirect costs associated with the depreciation of the infrastructure (greenhouse and equipment) [18]. Considering that the average selling price of papaya paid to farmers is around 1.1 EUR kg −1 in the main Spanish cooperative (M Casas, pers.…”

Papaya is a tropical crop increasingly cultivated in the greenhouses of subtropical regions such as South East Spain, where the determination of the best planting season is important to ensure a stable fruit production and quality during the year. In this work, we studied plant growth, yield, and fruit quality, comparing spring and autumn planting seasons in ‘Intenzza’ cultivar. The results showed that planting in spring favors plant growth, leading to an earlier entry into production. Total yield and fruit quality were similar in both planting seasons, although the spring cycle provided higher profits due to greater commercial yield and lower discards. Our results confirm that adverse environmental conditions affect the crop in a similar way regardless of the planting season, so different growing cycles are not very useful for filling the production gaps and fighting against seasonality in our region, unless unfavorable climate conditions are avoided inside the greenhouse.

“…Results obtained by Ruas et al (2022) demonstrated that hydric stress in the Aliança papaya genotype promoted a reduction in growth, as observed by a reduction in leaf area, stem diameter, and plant height. Salinas et al (2021) pointed out that temperatures below 20 ºC or above 35 ºC may induce a reduction in productivity and fruit quality, in addition to poor flower formation.…”

“…In 2020, Brazil produced approximately 1.235 million tons of papaya fruit (FAO, 2020). As papaya is extremely sensitive to abiotic stresses, climatic alterations may compromise its yield, leaf area, growth, fruit quality, and other characteristics (Ruas et al, 2022;Salinas et al, 2021).…”

Papaya cultivation is widespread in Brazil, particularly in the states of Bahia and Espírito Santo, where most commercial plantations are concentrated. Owing to the economic and social importance of papaya, the present study aimed to determine the explanatory variables between the genotypes of two cultivars: Golden (from the Soil group) and Tainung Nº 1 hybrid (from the Formosa group), cultivated under high temperatures and hydric stress. The genotypes containing more desirable agronomic characteristics were identified for use in plant genetic improvement programs. Principal component analysis (PCA) was applied to select the desirable genotypes for Golden and Tainung Nº 1 cultivars based on specific variables analyzed for two groups of variables; for group 1, the plant height, stem diameter, leaf length, leaf width, and leaf number were analyzed, whereas for group 2, the leaf and root dry mass, stem dry mass and fresh mass of 10 discs, fresh mass, and stem and root fresh mass were analyzed. When exposed to hydric and thermal stress, the Tainung Nº 1 cultivar outperformed the Golden cultivar for the evaluation characteristics selected for use in genetic improvement programs.

“…Additionally, fruit quality factors including skin color, acidity, and TSS were not affected. Protected cultivation and the use of greenhouses offer an affordable and cost-effective strategy for papaya cultivation, especially in regions where open field cultivation, whether due to climate, soil, or other factors, is not feasible [63]. The compactness of the protected system producing large volumes of high quality, uniform fruit, aligned with readily available packaging and transport facilities lends itself to supplying both long and short distance high-value markets.…”

Papaya (Carica papaya L) is a versatile tropical fruit with its usage ranging from consumption, cosmetics, to pharmaceuticals. In 2020, it was the third most-produced tropical fruit crop in the world. Papaya is a trioecious herbaceous plant with distinct flower and fruit morphological appearances. The fruits from hermaphrodite papaya are favorable for both consumption and processing due to their superior quality. Papaya has a genome size of 372 Mb and chromosome of 2n =18. The male and hermaphrodite papaya have XY and XYh sex chromosomes, respectively, while the female has XX. Using omics and bioinformatics approaches, papaya cultivars with desired fruit quality can be selected and identified from germplasm for incorporation in breeding programs. Papaya production can be done either in open fields or under protected cultivation. Open field cultivation provides for large-scale production, but with the disadvantages of variability in fruit yield, quality, and limitations on growing and harvesting seasons. Under protected cultivation, papaya can be cultivated in all seasons, whilst delivering higher yields. Conversely, multidisciplinary approaches with selected papaya cultivars, good farm management, and suitable conditions provide high yields of quality fruit for both consumption and processing, whilst minimizing the adverse effects related to environmental conditions.
