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.

ABSTRACT Balanced uptake of micronutrients by the passion fruit plant is essential for increased production and fruit quality. However, similar fertilizer management in varieties with different productive capacities and high levels of nitrogen and potassium can cause nutritional disorders in plants. The objective of this study was to evaluate leaf micronutrient concentrations and contents in passion fruit as affected by two different sampling methods, different N-K fertilization proportions, and different cultivars. The study was conducted in a randomized block design, with three replications, following a 4 × 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 ofN-K2O fertilizer (0-0, 50-125, 100-250, 150-375, 200-500, and 250-625 kg ha-1 year-1). Two leaf sampling methods (leaf located at a position adjacent to the fruit, and leaf located at the end of the fruit-bearing branch) were adopted for nutritional assessment. At 240 days after planting passion fruit seedlings in the experimental area, 20 leaves per plot were sampled. Higher accumulated micronutrient contents were obtained in the adjacent leaves, possibly because of greater leaf weight (more fully developed leaf) compared to the standard leaf. The cultivar IAC 275 had lower concentration and content of Cu, Fe, e Mn in the adjacent leaf, indicating variations in the levels of micronutrients among the cultivars and different micronutrient demands by the cultivars studied. N and K fertilization had less effect on leaf micronutrient concentration and content, but the Zn concentration and content decreased in the standard leaf of the BRS Gigante Amarelo cultivar, and Cu decreased in the standard leaf of the BRS Ouro Vermelho cultivar.

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.

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.

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.

The yellow passion fruit (Passiflora edulis f. flavicarpa Degener) crops have been gaining notoriety in Brazil, whose cultivation extends to almost all regions. The aim of this study was to evaluate the growth of yellow passion fruit seedlings in response to the interaction between substrate composition and irrigation water salinity levels. The experimental trial was installed in a randomized block design, with a factorial scheme (3x6) consisting of two factors: three levels of salinity and six types of substrates, distributed in four replications, each plot consisting of a polyethylene bag composed of two plants. The factor levels of salinity, electrical conductivity: 0.3, 1.2 and 2.1 dSm-1 did not influence the physiological growth and development of the seedlings, the substrates resulted in statistically significant effects, the cattle manure presented the highest percentage in levels of physiological growth and development of the plant.

The yellow passion fruit (Passiflora edulis f. flavicarpa) needs pollinators for fructification due to the existence of mechanisms that impede self-pollinating. Pollinators of great efficiency for the yellow passion fruit in Brazil are the bumblebee species (Xylocopa frontalis, X. grisescens and X. Suspecta). Deforestation by agricultural expansion in the region has a negative impact on these pollinators’ populations, leaving space for the action of cleptobiotic species with further damage to fruit production. The objective of this study was to evaluate the frequency of pollinating bees and floral visitors during yellow passion fruit culture’s post anthesis period in Northern Paraná and its fructification effects. Three passion fruit plantations in Northern Paraná were evaluated in the counties of Londrina and Assaí. Transect census were realized in each area, delimiting two 50 meter-paths, where the presence of bee in the open flowers was registered. Transects were run through for five minutes, every 15 minutes, starting at 1 pm and finishing at 8 pm. Results showed that the bumblebees present in the Northern Paraná region were the Xylocopa frontalis and X. suspecta, with the predominance of the first. Highest fructification rates occurred in the areas with more frequency of bumblebees and low frequency of cleptobiotic bees. Lowest fructification rates were due to the absence of bumblebees or high frequency of cleptobiotic bees

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 use of advanced seedlings associated with the annual cultivation of passion fruit are important management techniques for living with the fruit-hardening virus (FEV). However, this technology still needs information on nitrogen fertilization and spacing between plants, so that it is possible to recover crop’s productivity. The objective of this research was to identify the nitrogen dose (N) and the most suitable spacing for annual orchards installed with advanced seedlings (1.2 m high) of yellow passion fruit. The experiment was carried out in the field, in Mogi Mirim, SP, between October 2017 and July 2018. A randomized block design was used in subdivided plots; the treatments were doses of N in coverage such as 0, 60, 120, 180 and 240 kg ha-1 and spacing between plants of 2.0 and 4.0 m and 3.0 m between lines. The dose found for maximum production, 15.4 kg of fruit pl-1, and adequate physical-chemical quality of the fruit for the yellow passion fruit was 130.7 kg ha-1 of N. The most densified spacing, of 2 x 3 m, provided greater productivity and number of thousand fruits per hectare, respectively, 20.7 t ha-1 and 139.5 thousand fruits ha-1.
