Abstract Brazil is the largest producer of passion fruit worldwide, however diseases have been reducing passion fruit productivity, and limiting its cultivation for several years in a row in the same area. The proposal of this study was to evaluate diseases intensity and productivity of yellow passion fruit in vertical and overhead trellis systems, during two seasons, in annual cycle. The experiment was realized in a commercial orchard of yellow passion fruit in the municipality of Araquari, SC, in the 2013/14 and 2014/15 seasons. The treatments were vertical and overhead trellis systems, tested in a randomized complete block design, with eight replications. The agronomic practices were performed according to the culture recommendations and naturally pollinated althoght no disease control was applied. Anthracnose, bacterial blight, cladosporiosis and passion fruit woodiness severities were assessed in two seasons, from December to June, after establishment of the trellis systems. Production of fruits per plant and estimated productivity were determined in both seasons. There were no differences in diseases severity in both systems and seasons. The overhead trellis system was more productive than the vertical trellis system, 78.1% and 57.1% respectively, in the 2013/14 and 2014/15 seasons. Overhead trellis system showed to be the most adequate for yellow passion fruit production.

ABSTRACT Nitrogen and potassium fertilization and assessment of adequate nutritional status are essential for increasing fruit production of passion fruit. However, studies related to characterization of the leaf nutrient concentration and content in passion fruit with different production capacities are scarce in the literature in Brazil. The objective of this study was to evaluate macronutrient leaf concentration and content in different parts of the reproductive shoot of yellow passion fruit subjected to different ratios of N and K fertilization. The study was conducted in a randomized block design, with three replications, following a 4 x 6 factorial arrangement consisting of four cultivars of yellow passion fruit (BRS Gigante Amarelo, IAC 275, BRS Ouro Vermelho, and BRS Sol do Cerrado) and six application rates of N-K2O fertilizer (0-0, 50-125, 100-250, 150-375, 200-500, and 250-625 kg ha-1 year-1). Two leaf sampling methods were adopted (leaf located at a position adjacent to the fruit, and leaf located at the end of the reproductive branch) for nutritional assessment. The leaf located at the adjacent position had lower N, P, K, Mg, and S concentration and higher Ca concentration than the concentrations observed in the standard leaf. However, the higher leaf dry matter in adjacent leaves resulted in increased macronutrient concentration/content. The increase in N-K fertilizations inhibited Ca and Mg content in the leaves adjacent to the fruit of the Gigante Amarelo, IAC, and Ouro Vermelho passion fruit cultivars, but did not affect Ca and Mg content in the standard leaf. The passion fruit cultivars showed different leaf nutrient contents after N-K fertilization, indicating variable nutritional demands and the need for specific diagnostic methods for each cultivar.

The use of alternative inputs, derived from the fermentation of fresh organic matter, exerts significant importance in the pasiculture in partial substitution to synthetic commercial fertilizers. An experiment was conducted in the period from 2013 to 2014 to evaluate the effects of bovine biofertilizer and nitrogen, on leaf mineral composition of macronutrients, micronutrients and sodium and productivity of yellow passion fruit. The treatments were arranged in randomized blocks with three replicates and nine plants per plot. We arranged a 5 × 2 factorial scheme, referring to the bovine biofertilizer applied to the soil in the liquid form (B) in the proportions in water (W) of 0 (0B + 4W); 25 (1B + 3W); 50 (2B + 2W); 75 (3B + 1W) and 100% (4B + 0W), in the soil without and with nitrogen. The seedlings were developed from fruit seeds with large size, oblique shape and mass. The bovine biofertilizer was applied at 4 L plant-1 in water, 7 days before and 90 days after transplanting of 50-day-old seedlings. The nitrogen was applied to the relevant plots every 30 days after transplantation of the seedlings until the end of the experiment. The resulrs showed that plants were adequately supplied in N, Mg, S, B, Cu and Zn, but deficient in P, K, Ca, Cu, Fe and Mn at the beginning of flowering. The highest fruit production of 30.75 t ha 1 were obtained from the plants in soil with 100% of bovine biofertilizer and with nitrogen. Due to the higher fruit productivity in plants with biofertilizer bovine + nitrogen, compared to those treated with only bovine biofertilizer, it is verified that the organic input does not substitute the nitrogen for the cultivation of the yellow passion fruit.

ABSTRACT The objective of this study was to evaluate the effects of saline water irrigation management strategies and potassium doses on the concentration of photosynthetic pigments, gas exchange, and fruit production of ‘BRS GA1’ yellow passion fruit. The experiment was carried out under field conditions using a randomized block design, with treatments based on a 6 × 2 factorial scheme, related to six management strategies for irrigation with saline water (irrigation with low-salinity water throughout the crop cycle-WS; irrigation with high-salinity water in the vegetative stage-VE; flowering stage-FL; fruiting stage-FR; and successively in vegetative/flowering stages-VE/FL and vegetative/fruiting stages-VE/FR) and two doses of potassium (60 and 100% of the recommendation), with four replicates. The dose of 100% recommendation corresponded to 345 g of K2O plant-1 year-1. High electrical conductivity irrigation water (4.0 dS m-1) was used in different phenological stages according to treatment, alternating with water of low electrical conductivity (1.3 dS m-1). The synthesis of chlorophyll a and b, stomatal conductance, instantaneous carboxylation efficiency and water use efficiency of ‘BRS GA1’ yellow passion fruit were reduced under irrigation with water of 4.0 dS m-1 in all strategies adopted. Fertilization with 60% of the K recommendation promoted greater number of fruits and yellow passion fruit yield. Irrigation with 4.0 dS m-1 water in the vegetative/flowering and flowering stages reduced the yield of yellow passion fruit.

The passion fruit is one of thefruit that has been gaining more prominence in the fruit sector because it is widely used in food, pharmacology and ornamentation. Its cultivation in the northeastern region of Brazil presents some limitations due to the organic matter content of the soiland / or the use of water of high salinity in some properties. The objective of this study was to evaluate the effect of different types of manure and the interaction with different saline levels of irrigation water.The statistical design adopted was a randomized complete block design with 3 x 5 factorial design, with three types of manure (bovine, goat and poultry) and five saline levels (0.3, 1.3, 2.3, 3.3 ; 4.3 dS m-1) with four replicates and one plant per replicate. The data were analyzed using the statistical program Sisvar 5.3.It was concluded that there was no interaction between manure types and saline levels, however, goat manure favored the growth of yellow passion fruit seedlings. On the other hand, the increase in saline levels up to 4.3 dS m-1impaired the growth of all variables up to 60 DAS.

ABSTRACT Passion fruit productivity in the state of Acre is lower than the national average, influenced by several factors, among them water stress in rainfed cultivation. Thus, aiming at alternatives for the drought period, this study aimed to evaluate the economic profitability of the use of tall seedlings and long root system in the cultivation of organic yellow passion fruit. Five root lengths were evaluated: 25 cm; 50 cm; 75 cm; 100 cm and 125 cm in a randomized block design, with four blocks and four plants per plot. The experiment was carried out in the municipality of Rio Branco, state of Acre, at the “Seridó” Ecological Site from November 2015 to July 2017. For economic analysis, all fixed and varied costs such as seed production, orchard planting, crop management, phytosanitary control, harvesting and capital depreciation were considered. Analysis of variance and regression analysis were performed for productivity and economic indicators. Plants with root system with estimated length of 1.14 m promote higher fruit yield (7,613 kg ha-1), net revenue of R$ 17,665.44 ha-1, benefit/cost ratio of 2.5, profitability of 177.5%, remunerating the family labor with R$ 211.75 day-1. However, all treatments proved to be profitable.

Pollen Quantity

Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen resulted in higher seed yield per area, but the plant spacing did not affect this characteristic. Manual pollination, using a whole anther, did not differ from natural pollination in relation to seed yield and quality.

Hydrogen peroxide (H2O2) is a molecule that can flag plants under biotic and abiotic stress conditions. Among the kinds of stress, the salinity stress is the one that most usually affects plants. Consequently, the purpose hereof was to use hydrogen peroxide (H2O2) to mitigate the possible harmful effects of salinity in yellow passion fruit seedlings. We employed a randomized block design, in a 5 × 3 factorial scheme, corresponding to five irrigation water electric conductivity levels (0.3; 1.3; 2.3; 3.3; and 4.3 dS m-1) and three hydrogen peroxide concentrations (0; 5; and 15 μmol L-1), with four repetitions. The treatments were applied foliarly 7 and 15 days after the seedlings’ germination with hand sprayers. Sixty days after sowing, we evaluated the seedlings’ growth and quality variables, which finally proved that hydrogen peroxide mitigates the harmful effect of the irrigation water’s salinity up to 2 dS m-1 in the growth of yellow passion fruit seedlings at the concentration of 5 μmol/L. Nonetheless, excessive concentrations (15 μmol L-1) associated with high salt concentrations were proven detrimental to the seedlings’ phenological growth and quality.

ABSTRACT With this study, the objective was to determine the most economic management of irrigation water applied at different levels in the culture of passion fruit grown in conventional system and in polyethylene bags. The experiment was conducted in the city of Remanso, state of Bahia, Brazil. The experimental set-up was a randomized block design in a factorial design 2 (conventional system, and polyethylene bags of 100 L) x 5 (irrigation levels: 100%, 80%, 60%, 40% and 20% an irrigation management at field capacity) with four replications and four plants per plot. The treatments began 30 days after transplanting the seedlings to the field, and the analyzed variables were: plant height, stem diameter, leaf area and number of tertiary branches, of flower buds and fruits per plant. The data were interpreted by means of analyses of variance (test F) and means were compared by Tukey test at 5% probability of error. It was found that the yellow passion fruit got greater agronomic performance when grown in polyethylene bags, with irrigation management at 80 % field capacity.

Abstract A 10 year-old apple orchard, variety ‘Red Delicious’ was used in this test. Single tree plots, replicated 4 times/variety in a randomized complete block design, were sprayed to runoff (ca 3 gal/tree) with a hydraulic sprayer equipped with a handgun operated at 200 psi. Treatments were applied at petal fall (PF—11 May), 5th cover (5th—12 Jun) and 6th cover (6th—3 Aug). The orchard was treated with Captan for disease control as needed. Weekly ERM counts were made by randomly selecting 20 leaves/tree, brushing mites onto glass plates coated with Triton B-1956, and counting motile ERM and AF. Mite-days (MD) were calculated as: MD = MD1 + [(Ml + M2)/2 × 7], where MD1 = mitedays already accumulated, Ml = avg ERM/leaf on a given sample date and M2 = avg ERM/leaf on the next sample date. Leafhoppers (White apple and/or Rose) were evaluated at 1,3, 7, 14, and 21 days post treatment using a 20 leaves/tree (PF) or 50 leaves/tree (5th and 6th) sample. Predatory coccinellids were sampled by 3 minute counts of larvae and adults. At harvest, 100 fruit/tree were collected and weighed, evaluated for spray injury, and rated (0%-100%) for russeting. Data were transformed to sqrt(x + 1) or arcsine(x) before ANOVA and comparison of means.
