The aims of this study were to evaluate the physical and chemical change of pummelo fruit during storage with waxing and wrapping, and to determine the effect of waxing and wrapping and their  its interaction in affecting shelf life of pummelo fruits. This research was arranged in a randomized complete block design with two factors and three replications. The first factor was waxing consisted of without waxing, 10% beeswax, 5% beeswax, and chitosan. The second factor was wrapping consisted of without wrapping and wrapping using either transparent yellow or white plastic wrap. Pummelo fruits experience weight loss, reduced total soluble solid (TSS), decrease in firmness and total acidity during 48 days of storage in room temperature. Waxing using beeswax or wrapping using plastic wraps significantly suppressed weight loss and maintained fruit firmness compared to those without waxing and wrapping. However, waxing and wrapping did not significantly affect the quality of pummelo fruits. Based on the fruit’s weight loss, firmness, and panelist preferences, 5% or 10% bees wax can be used as waxing. Both transparent yellow and white plastic wraps can be used to maintain fruit weight, firmness, and appearances during storage.

Fertilization outside the season of Siam Orange (Citrus microcarpa L.) with Induction of Flowering and Dormancy Breaking Substances. The Siam orange (Citrus microcarpa L.) produces seasonal fruit with the on-season harvest from July to August while the off-season harvest, i.e. from February to September there is hardly any fruit, or very limited supply. The purpose of this study was to examine the response of flowering induction and dormancy-breaking substances to produce off-season fruits of Siam orange. This research began in April to December 2016. The experiment was arranged factorially with two factors using a randomized block design (RBD), with nine combination treatments and six replications. Flowering induction factors consist of three levels, namely Ik = Control, IP = Paclobutrazol at a dose of 7.5 g/l, and Im = cutting the tip of dormant twigs. Dormancy-breaking substances factor consists of three levels, namely Dk = Control, Db = BAP 200 ppm, and Dn = KNO3 300 ppm. The results of the experiment showed that the highest fruit weight per tree at off-season production was obtained by induction with paklobutrazol (28.86 kg) and the lowest was in control (12.75 kg). Flowering induction treatments was not significantly different effect on fruit quality of Siam orange, represented by weight per fruits, fruit diemater, total soluble solid and vitamine C content was not siginificant different among levels of treatment. Dormancy-breaking substances treatment also not significantly effect on fruit quality of Siam orange. Based on this research it is recommended to induce flower for off-season produce of Siam orange by pruning the tips of dormant twigs or by using paklobutrzol.

Tomato (Lycopersicon esculentum) is highly perishable and has potential for processing industries in bumper producing seasons in Nepal. The study on judicious use of nitrogen and potassium levels was aimed to explore the quality attributes along with the shelf life of tomato fruits. Three levels of nitrogen comprising 0 kg/ha (N0), 100 kg/ha (N100), 200 kg/ha (N200) and four levels of potassium 0 K2O kg/ha (K0), 80 K2O kg/ha (K80), 160 K2O kg/ha (K160), 240 K2O kg /ha (K240) were used as treatments in randomized complete block design with three replications at Chitwan (Inner Terai) Nepal. Tomatoes at breaker stage were harvested from the field and 10 fruits from each treatment per replication were kept for physiological weight loss, color rating and shelf life in ambient condition (17.5±3 0C and 80.5±6.5 % RH). Fruit quality with respect to physicochemical properties like firmness, TSS, TA, pH and Vitamin C was assessed at the end of shelf life. Higher potassium levels hasten color development and increased TSS, firmness and vitamin C content. Physiological weight loss was greatly reduced and extended shelf life was achieved with 100 kg N/ha and 240 kg K2O/ha.

The quality of seed needs to be considered in carrot seed production to maintain its productivity. The research aims to find out the response of stecklings age and plant spacing on carrot seed quality and production. This research was held on July 2018 – April 2019 in Berastagi field trial (1340 m MSL). The experiment used Randomized Complete Block Design (RCBD) with two factors, i.e., stecklings age (2 and 3 months) and plant spacing (25, 50, 75, and 100 cm), replicated four times (32 experiment units), 10 plants from each experiment units were taken as samples. The result showed that stecklings age and plant spacing were affected to plant vegetative and generative stages. The combination of 2-month stecklings and 50 cm plant spacing increased the number of secondary umble, if compared to cultivation, which was generally used by the farmer (3-month stecklings and 25 cm plant spacing). The best quality of carrot seed was obtained from the combination of 3-month stecklings and 50 cm plant spacing.

Abstract Background Two separate experiments were conducted in the minor season from September to November, 2019 and major season from March to May, 2020 to determining the type of soil amendment and transplanting age that can best improve the post-harvest quality and shelf life of sweet pepper fruits at Benso oil palm plantation of Adum Banso Estate in the Mpohor District of the Western Region of Ghana. The experiments were conducted as a 4 × 2 factorial, arranged in a Randomized Complete Block Design. Four fertilizer treatments including no fertilizer (control), 10 tons/ha of poultry manure, 300 kg/ha of NPK 15-15-15 and 5 t/ha of poultry manure + 150 kg/ha of NPK 15-15-15 and two ages of transplants including 6-week-old seedlings and 7-week-old seedlings were applied during the cultivation periods and were later evaluated of their effects on the post-harvest quality and shelf life of harvested fruits after a two-weeks storage period. Data collected on weight loss, shrinkage, decayed fruits and shelf life of harvested fruits were subjected to analysis of variance using the Genstat Statistical package. The least significant difference criterion was used to separate treatment means at 5% probability. Results Post-harvest qualities of sweet pepper fruits were not significantly influenced by age of transplant throughout the study. Fertilizer application generally increased percentage fruit weight loss, fruit shrinkage, fruit decay and reduced shelf life of sweet pepper fruits in the major season. Sole application of poultry manure mostly enhanced post-harvest quality of sweet pepper fruits in the minor rainy season, but fruit shelf life was improved if no fertilizer was applied. Application of a combination of poultry manure and NPK 15-15-15 to 6-week-old transplants gave relatively low fruit weight loss and shrinkage values. Generally, fruit quality and shelf life were enhanced in 6-week-old transplants treated with no fertilizer. Conclusions The use of poultry manure alone should be encouraged to probably increase yield while improving the quality and shelf life of harvested sweet pepper fruits. Transplanting of 6-week-old seedlings is also encouraged for quality harvested fruits and extended shelf life.

This study was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University, Dhaka during October, 2015 to January, 2016 to determine the effects of mulches and phosphorus on the growth and yield of squash (Cucurbita pepo). The experiment consisted of two factors. Factor A: different mulches and Factor B: phosphorus (3 levels). The experiment was laid out in a Randomized Complete Block Design with three replications. Mulches and phosphorus showed significant effects on most of the parameters. In case of mulches, highest individual fruit weight (328.0 g) and fruit yield (37.0 tha-1) was recorded from black polythene, whereas the lowest fruit weight (280.8 g) and fruit yield (21.5 tha-1) was recorded from control. In case of phosphorus, highest individual fruit weight (300.4 g) and fruit yield (31.3 tha-1) was recorded from 90 kg P2O5/ha,whereas the lowest fruit weight (290.4 g) and fruit yield (26.2 tha-1) was recorded from control. For combination, highest individual fruit weight (338.2 g) and fruit yield (39.9 t ha-1) were recorded from black polythene with 90 kg P2O5/ha while the lowest individual fruit weight (272.2 g) and fruit yield (19.7 t ha-1) were recorded from control treatment. Black polythene mulch with 90 kg P2O5/ha was found suitable for squash cultivation under the condition of the study. The Agriculturists 2018; 16(2) 25-34

A detailed study was carried out with the postharvest mangoes (namely, the Langra and the Khirshapat) treated with different levels of Bavistin DF (BDF) solution (namely, 250, 500, and 750 ppm) for obtaining results on biochemical changes as well as storability of postharvest mango. The experiment was laid out in randomized complete block design with three replicates. The results of the experiments exhibited that only the single effect of varieties was found to be significant in most of the parameters studied. The Langra enriched a greater quantity of titratable acidity and total soluble solid (TSS) at 3rd day, over the Khirshapat. On the other hand, Khirshapat showed increased pulp pH and TSS at all the storage duration. The results explored that some physicochemical properties, namely, pulp pH, TSS, sugar (total, reducing, and nonreducing), and titratable acidity along with shelf life drastically decreased from untreated mangoes. Bavistin DF with the doses of 750 ppm showed better results in delaying the changes in physicochemical properties and extended shelf life.

Abstract: The objective of this work was to evaluate the productivity and quality of papaya fruits (Carica papaya) of the Solo (12 genotypes) and Formosa (9 genotypes) heterotic groups over two harvest seasons. The experiment was conducted under field conditions in the municipality of Pinheiros, in the state of Espírito Santo, Brazil, in a randomized complete block design. Ten morpho-agronomic and physicochemical variables of the fruits were measured in winter (210-300 days after planting) and summer (450-540 days after planting). The data were subjected to the combined analysis of variance, to the breakdown of the genotype x environment interactions, and to the grouping of means by the Scott-Knott test. Although harvest season affected the evaluated characteristics, it did not alter the classification of the genotype. In the Solo group, the H 36-45 and UC 15 hybrids stand out due to their greater productivity, fruit weight, and soluble solids contents. In the Formosa group, the Rubi Incaper 511 cultivar shows greater productivity, higher number of commercial fruits, and lower number of deformed fruits over both evaluated harvest seasons.

ABSTRACT Tomatoes are an important component of the human diet because they are rich in minerals and antioxidants that sequester free radicals in cells, preventing various disorders that affect human health. Here, we aimed to evaluate the effects of different nitrogen sources and concentrations on antioxidant capacity and physical and chemical quality of tomato fruit. The experiment was conducted in Vitória da Conquista, state of Bahia, Brazil, in the experimental field of Universidade Estadual do Sudoeste da Bahia. The experimental setup included a randomized block design with four replicates in a factorial layout of 3 × 3 + 1 (control), for a total of 40 plots. The three treatments comprised different nitrogen sources (calcium nitrate, urea, and ammonium sulfate), applied in three doses (140, 280, and 420 kg ha-1). We evaluated firmness, pH, titratable acidity - TA, soluble solid - SS, SS/TA ratio, ascorbic acid, carotenoids, flavonoids, phenolic compounds and DPPH inhibition, were evaluated after samples were harvested. However, increasing concentrations of N adversely affected the acidity and led to an increase in the SS/TA ratio. Increasing the N concentration also reduced the content of bioactive compounds. excluding carotenoids, which consequently impaired antioxidant activity.

In the present study the extended storage life of cut apples (Red Delicious) examined using nano zeolite particles and potassium permanganate. Titratable acidity, total soluble solids, pH and weight loss was measured .Visual observations of fruits during storage were investigated. The results showed that pH, soluble solids and fruit weight loss has increased during storage. The acidity of fruits stored with nano zeolite was less decreased as compared with potassium permanganate. The growth of moulds on preserved fruit with nano zeolite was much less after 10 days of storage as compared with potassium permanganate.DOI: http://dx.doi.org/10.3126/ijls.v9i2.12050 International Journal of Life Sciences 9 (2) : 2015; 55-60
