“…Due to its advantageous nutritional properties, good taste, and low-calorie content, this fruit is highly appreciated by consumers (Saquet, 2019). Although a large number of pears are consumed fresh (in nature), they are also commonly consumed in some form after processing, such as syrups, preserves, purees, nectars, and droughts (Lordan et al, 2019;Proietti et al, 2018). The consumption of dried pears slices brings consumers a new experience of sensations due to the relationships between visual appearance, firmness, and organoleptic characteristics (Ribeiro, Aguiar-Oliveira, & Maldonado, 2016;Torregrosa, Echeverria, Illa, & Giné-Bordonaba, 2019).…”

Over the last few decades, the drying process has proven to be a fundamental operation within the food industry, as it prolongs the shelf life and reduces the levels of deterioration of the product. Infrared drying has gained great attention in recent years as it promotes more uniform and energy-efficient drying. Given the above, this study aimed to perform infrared drying of pear slices at different temperatures, evaluating the drying kinetics, and the thermodynamic analysis. The pear slices 3-mm thick were dried in an infrared dryer at temperatures between 50 and 100 C until constant mass.Different mathematical models were fitted to the experimental data to represent drying as a function of time. Energy and exergy analysis were performed by applying the first and second laws of thermodynamics. The Henderson and Pabis modified model

“…This affects the PGR applied to the Salak Pondoh plant. Research by Lordan (et al 2019) stated that the administration of GA3 on day seven after pollination did not increase the fruit size, but only increased the fruit formation. This is possibly what causes the PGR to not increase the size of the Salak Pondoh fruit.…”

Plant growth regulators (PGRs) and proper fertilisers are used to increase quality of the Salak Pondoh, such as in the plant production, fruit number and size. This study aims to determine the type and dosage of PGRs and the best type of fertiliser to increase the production bunch and fruit of Salak Pondoh. The method used was a Factorial Completely Randomised Design (FCRD) with 36 treatments (excluding the control) and 3 replications. Three treatments were conducted: first, as a control, no PGR treatment + fertilisation (no fertilisation, manure, and NPK). Second, a 3 × 3 factorial scheme. Treatment of PGR GA3 (50, 100, 150 ppm) + fertilisation (no fertilisation, manure, and NPK). Third, a 3 × 3 × 3 factorial scheme was used. Treatment of PGR Gracilaria sp. extract (50, 100, 150 ppm) with different solvents (n-Hexane, methylene-chloride, ethanol) + fertilisation (no fertilisation, manure, and NPK). The parameters observed were the number length, area of the bunch, length and area of the fruit. The results showed the highest number of bunches was found in PGR GA3 50 ppm. While, the highest bunch area was found in PGR Gracilaria sp. ethanol 150 ppm. The PGRs only increased the formation of the bunches and did not increase the length and width of the bunches and the fruit size. Fertilisation affected the Salak production in the form of the number, length and width of the bunches, and the fruit size. In addition, the fertiliser increased the number of the bunches, bunch area, and length and area of the fruit. The interaction of the PGR and fertilisation had no significant effect on increasing the Salak Pondoh production. The best result in increasing the Salak Pondoh production was PGR Gracilaria sp. ethanol 100 ppm with manure fertilisation.

“…Furthermore, in these years the mason bees' pollination effect was presumably also averaged out by other factors. For instance, overnight frost events during the pear flowering periods (which were present in 2019, and very severe in 2017), undoubtedly had an overall substantial impact on fruit set and fruit development [62]. An analogous analysis in which 16 outliers were removed from the dataset delivered similar outcomes (see Supplementary Table S7).…”

Recently, the concept of Integrated Pest Management (IPM) was further extended into Integrated Pest and Pollinator Management (IPPM). Implementation of IPPM strategies entails the combination of actions for pest and pollinator management providing complementary or synergistic benefits for yield and/or quality of the harvest. The aim of this study was to examine IPPM elements (i.e., mixed hedgerow, nesting boxes for mason bees, Osmia spp.) and demonstrate their impact in the practical context of modern commercial fruit cultivation in a 4-year case study in an intensive ‘Conference’ pear orchard. The outcomes of visual observations during transect walks and molecular analysis of pollen collected by mason bees, showed the importance of additional floral resources for the presence of mason bees and other pollinating insects in the orchard environment. Pear quality assessments indicated that insect-mediated pollination had a significant positive impact, with a tendency for higher quality pears in the close vicinity of Osmia nesting boxes. However, despite the fact that pear pollen was also detected in Osmia spp. nest cells, the amount and frequency of pear pollen collection for their nest built-up turned out to be rather low. In the same intensive pear orchard studied for pollination effects, we simultaneously demonstrate the impact of a mixed hedgerow to enhance integrated pest control.
