Due to high respiration and ethylene production, tomato (Solanum lycopersicum) is highly perishable horticulture produce that deteriorates faster during the post-harvest storage period. Calcium nutrition is important to overcome these losses as it helps in retarding ripening process during storage and improve the post-harvest quality tomatoes. Hence a field experiment was conducted with different calcium sources and levels viz., Calcium sulphate, Calcium Nitrate, Calcium silicate, Poultry manure and Pressmud applied at 0, 20, 40, 60 and 80 kg Ca ha-1. A storage study was conducted in a factorial completely randomized block design (FCRD) to ensure the effective role of calcium in post-harvest quality of hybrid tomato. Tomatoes were analyzed for pH of fruit juice, firmness, titratable acidity, total soluble solids, moisture content and physiological loss at five days intervals upto 15 days. The results revealed thatCalcium sources and levels had highly significant impacts on the quality of tomato fruits. The tomatoes harvested from the plot applied with poultry manure at 80 kg Ca ha-1 retained the highest fruit firmness(3.76 N m-1), moisture content (88.2%) and the lowest weight loss (8.82%) in fruit, highertitratable acidity (0.41%), lesser pH (3.61)andtotal soluble solids (4.23 ˚Brix). Hence the application of poultry manure at 80 kg Ca ha-1was beneficial in improving the quality and extending the storage life of hybrid tomatoes.

Tomato is one of the most consumed vegetables in the world. This work aimed to evaluate post-harvest quality of Italian Saladete tomatoes grown in a protected environment, with different ways of calcium application, in the Middle São Francisco Valley. Consisting of five Italian tomato hybrids (Anjico, Gabrielle, Liberty, Ty 2006 and Shanty), and three different ways of calcium application (T0 without application of calcium; T1 application of calcium in the opening flower, and T2 weekly application of calcium in the fruit).  Poductivity, average fruit mass, incidence of apical rot, fruit firmness, soluble solids (SS), titratable acidity (AT), and pH, were analized. The experimental design used was a completely randomized block design in a factorial scheme (five cultivars x three ways of calcium application), with three repetition and using two central plants as useful plot for analysis, except for fruit firmness that was carried out in a completely randomized design, using tree fruits per analysis. According to the results obtained, hybrids of Italian saladete tomatoes behaved in a satisfactory manner, therefore it is recommended to cultivate hybrids of Italian saladete tomatoes in the Middle São Francisco Valley, mainly hybrid Anjico. Calcium application way did not interfere with post-harvest attributes.

Aims: The objective was to determine the influence of the onion harvest time "Baia Periforme" on post-harvest quality of the bulbs during storage. Study Design: The experiment was conducted in a randomized block design with three treatments, six replicates with two bulbs each. Place and Duration of Study: Departamento de Fitotecnia, Universidade Federal de Viçosa, between June 2017 and July 2018. Methodology: Seedlings, 20 days old, were transplanted into 20 cm spacing between rows and 10 cm between plants. The bulbs were harvested 120 days after transplanting with manual tipping of the pseudo-stem (T1), with 50 (T2) or 75% (T3) of the bulbs popped. The soluble sugars (SS), non-reducing sugars (NRS), reducing sugars (RS), total soluble solids (TSS), titratable acidity of phenolic compounds and alinase activity was determined every 30 days for 90 days. Results: The content of SS, TSS, phenolic compounds and alinase activity increased in the onions of T2, resulting in more sweet and pungent bulbs due to the higher content of acidity and phenolic compounds. Conclusion: The post-harvest quality of onion bulbs "Baia Periforme" was maintained when they were harvested with 50% of bulbs popped.

The present work had as objective to evaluate the physical-chemical characteristics of commercial tomato fruits grafted on different solanaceous species. The experiment was conducted in a greenhouse, in a randomized complete block design, with four blocks and six treatments, being the rootstocks: cocona (Solanum sessiliflorum); two cultivars of eggplant (Solanum aethiopicum), Long Light Green and Big Hill; jurubebão (Solanum lycocarpum) and jurubeba juna (Solanum stramonifolium), grafted with the tomato cultivar Santa Cruz Kada, and the control treatment was represented by the self-grafted tomato. Three consecutive harvests were spaced seven days after the production stabilization, and the characteristics fruits analyzed were Total Soluble Solids (ºBrix), pH, Titratable Acidity (percentage of citric acid) and TSS/TA. A statistically significant difference was found in the Tukey’s test at 5% probability in the titratable acidity, pH and fruit pulp flavor, among the evaluated treatments, while the soluble solids content did not differ between treatments in any of the harvests, but the values remained within the considered adequate for the tomato in natura in the current literature. There was a decrease in fruit flavor in all treatments, and fruit pH drop in all treatments with the exception of jurubebão, with the advancement of plant age, while the titratable acidity had an inverse behavior. The evaluated rootstocks can be used in the tomato crop, without prejudice to the quality of the tomato fruit produced.

ABSTRACT Mechanizing the harvest of Jalapeño pepper involves changes in the production system. Spacings between plants in rows (10 to 40 cm; 60 cm fixed between rows) were evaluated in relation to plant architecture, productivity and fruit quality of cultivar BRS Sarakura during three years, in a randomized complete block design with five replicates. Productivity (41.9 to 78.8 t ha-1) and plant height (40.1 to 47.3 cm) responded linearly to density; on the other hand, productivity per plant responded negatively (0.48 to 1.04 kg plant-1). The stem first bifurcation height was little influenced. Fruit chemical analyses were carried out in the second year of the experiment; spacing significantly influenced pH (5.36 to 4.84), total titratable acidity (TTA) (0.48 to 0.36%) and total soluble solids (TSS)/TTA ratio (11.5 to 15.6); no influence on TSS (5.65%) was noticed, though. The increase of plant population provided an increase in productivity without affecting fruit quality; the highest height of the first bifurcation achieved may not be enough to enable mechanized harvesting of the cultivar BRS Sarakura.

Worldwide, the second most traded fruit is banana, which is highly appreciated by Brazilian consumers. Moreover, new technologies have been used to improve fruit quality during cultivation. This study aimed to assess the influence of plastic bag colors on the production and quality of banana ‘BRS Conquista’. The treatments consisted of the use of commercial polypropylene bags e colored white, black, red or blue, in addition to the control (non-bagged). This study used a randomized complete block design with five treatments, four replicates and four plants per plot, totalling 80 plants. The assessments consisted of bunch mass; rachis mass; fruit total mass; mean cluster mass; number of fruits per bunch and per cluster; and fruit length and diameter; along with fruits physicochemical traits, such as soluble solids, titratable acidity, pulp/peel ratio and maturation index. The results indicated that no interference was obtained from the different plastic bag colors in the productive variables. However, a greater content of soluble solids was observed in the non-bagged bunches.

Brazil has a large variety of native and exotic fruit species, including the gabiroba, which can be sources of income for the population. The objective of this study was to evaluate the post-harvest behavior of gabiroba fruit by maturity stage and storage temperature. The fruits were divided into two lots and stored at temperatures of 6, 12, 24 and 30°C. The first batch was used for the physical and chemical analysis of acidity, soluble solids, firmness, percentage of green color, and visual analysis; this batch was composed of green and yellow-green fruit. The second lot was intended for breath analysis, composed of green, yellow-green, and yellow fruits. The experiment was conducted in a completely randomized design with five replications. Data were analyzed using descriptive statistics. Considering the evaluated characteristics, the gabiroba soluble solid/titratable acidity ratio values should be approximately 4.0 for the fruits to be considered acceptable for consumption. For the preservation of the post-harvest quality of gabiroba, it is indicated that the harvest is carried out at the green stage of maturation and that they are stored at a temperature of 6°C. The highest respiratory rates were observed in fruits harvested at the yellow stage, not being recommended its storage.

Silicon (Si) is a mineral element that provides many benefits to plants and may also assist in tolerance to abiotic stresses such as salinity. The aim of the study was to evaluate the use of Si as a possible attenuator of the deleterious effects of salinity on growth and post-harvest of lettuce. A completely randomized design with four replicates was performed in a 3 × 2 factorial, consisting of three salinity levels (1.65, 3.65, 7.65 dS m-1) and two levels of silicon (0.0 and 2.0 mM). Salinity reduced all variables related to plant growth. For shoot fresh and dry mass, it was observed that NaCl caused a reduction of 79.80 and 80%, respectively, in comparison to the control. However, parameters related to post-harvest such as titratable acidity, soluble solids and vitamin C increased with salinity. Although not effective in reducing saline stress on plant growth, Si provided improvements in the variables related to lettuce post-harvest. Salinity significantly reduced plant growth in the presence and absence of Si, but provided better post-harvest quality with Si.

ABSTRACT Okra, Abelmoschus esculentus (L.) Moench, is a vegetable with annual fruit native to hot regions of Africa, well adapted to the conditions of the Northeast and Southeast regions of Brazil, where it is widely used by small farmers. This study aimed to evaluate the effect of mineral and organic fertilization on the production and quality of okra fruits. The experiment was conducted in randomized block design, with three replicates and eleven treatments defined according to a Baconian matrix. Treatments consisted of doses of N (0, 100, 200 and 300 kg ha-1), P (0, 100, 200 and 300 kg ha-1) and K (0, 80, 160 and 240 kg ha-1), as well as absence and presence of organic compost (30 t ha-1). The following parameters were evaluated: plant height, stem diameter, number of leaves, production of fruits plant-1, number of fruits plant-1, fruit length and diameter and fruit quality (pH, soluble solids, titratable acidity, vitamin C and electrical conductivity). The crop is demanding in terms of K and N fertilizations, with increments of 15.8 and 36% in the mean number and diameter of fruits, respectively. Organic fertilization did not influence the vegetative growth of okra, but was beneficial to the production of fruits with higher vitamin C content, 52% higher than the contents found in fruits produced without such input.

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.

Chilling Hours

Despite the expansion of viticulture in Brazil, the lack of chilling hours is a factor that requires the use of growth inducers to promote sprouting. Erger™ is a product of low toxicity and efficient in the bud induction of apple. However, there is a lack of studies testing such a product on the grapevine. This research was carried out to evaluate the sprouting and phenological cycle of ‘Fiano’ grapevine after Erger™ and calcium nitrate application in comparison to hydrogen cyanamide, as well as characterizing its production in Brazil. The experiment was carried out in Campo Largo, PR, under a trellis system, with plants spaced at 1.25 × 2.7 meters. The experimental design was a randomized complete block design with four replications and three plants per plot. Different concentrations of Erger™ and calcium nitrate (3%, 5%, 7%, and control) were tested compared to the standard dose of Dormex™ (4%) to induce sprouting in ‘Fiano’ grapevine, while phenological aspects of this cultivar were evaluated following the BBCH scale. Soluble solids content, titratable acidity, and pH were evaluated weekly after the beginning of berry maturation. The main biometric and qualitative characteristics of bunches were evaluated at harvest. All treatments presented satisfactory sprouting rates in 2014, but a lower cold accumulation was observed in 2015, and Erger™ application significantly increased sprouting when compared to the control. Plants treated with Erger™ had a delay in sprouting in the two years of study, requiring more time to reach a satisfactory percentage of open buds. The anticipation of sprouting was also observed in all treatments in the second agricultural season due to higher temperatures in relation to the previous year when the occurrence of low temperatures led to a longer time to start bud opening, which was related to ecodormancy. The cultivar Fiano is productive and adapted to the conditions of Campo Largo, PR, Brazil.
