“…Although the yellow passion fruit cultivation is realized for up to three consecutive years in commercial orchard (HAFLE et al, 2009), when CABMV is present, the recommendation is for annual cycle management to increase productivity (SAMPAIO et al, 2008;WEBER et al, 2016), and to coexist with the disease. For polycyclic diseases, such as cladosporiosis, anthracnose, bacterial blight and fruit woodiness, the aerial dispersion of pathogens, as well as aphids, is an important factor in the spatial and temporal increase of epidemics, because these diseases are initiated by primary inoculum, and secondary inoculum causes several infection cycles in a season (GOBBIN et al, 2005).…”

“…Besides that, few information are available at the literature proving those strategies could reduce disease and help maintain productivity in the crop production system. Some authors recommended cultivation of passion fruit in an annual production cycle (CERQUEIRA-SILVA et al, 2014;WEBER et al, 2016) . The most common trellis systems are vertical, which trains plants to grow in a vertical architecture, and overhead, in which plants are trained to grow horizontally.…”

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.

Maracujazeiro-amarelo no sistema de condução em caramanchão não difere na intensidade de doenças e é mais produtivo em relação ao sistema em espaldeiraResumo -O Brasil é o principal produtor mundial de maracujá, mas as ocorrências de doenças têm reduzido sua produtividade e limitado seu cultivo por vários anos em sequência na mesma área. O objetivo deste trabalho foi avaliar a severidade de doenças e a produtividade nos sistemas de condução em espaldeira e em caramanchão durante duas safras, em cultivo anual. Nas safras de 2013/2014 e 2014/2015 o trabalho foi realizado em pomar comercial de maracujazeiro-amarelo em Araquari-SC, testando-se como tratamentos os sistemas de condução em espadeira e em caramanchão em DBC, com oito repetições. Foram realizados os tratos culturais recomendados para a cultura, polinização natural e avaliadas nas duas safras a intensidade da antracnose, da mancha-bacteriana, da cladosporiose e da virose do endurecimento no fruto, de dezembro a junho, a partir do estabelecimento dos sistemas de condução. A produção de frutos por planta e a produtividade estimada foram determinadas. Não houve diferenças nas severidades das doenças avaliadas nos dois sistemas e safras. O sistema em caramanchão mostrou-se mais produtivo (78,1% e 57,1%) do que o sistema em espaldeira, nas safras de 2013/2014 e 2014/2015, respectivamente, demonstrando ser o melhor sistema de condução para o maracujazeiro-amarelo.

“…According to Cavichioli et al [4] the largest spacing within plants increases the number of fruits per plant; for the referred authors, the smaller spacing promotes a reduction of the number of flowers per plant, of the pollination efficiency, of the photosynthetic rate by the high shading and reduction in the development of its branching; however, when evaluating the productive development of the yellow passion fruit cv. Sul Brasil in different spacings, it was verified that the difference in the number of fruits per plant did not reflect in difference in the yield, that because the reduction in the individual development was compensated by the larger plant population.…”

“…Conversely, Alvarez et al [8] obtained an increase in the yield of the passion fruit variety INIAP 2009 with the increase in the planting density, in Ecuador. In the Southern region of Brazil, Weber et al [4] did not identify influence of the planting density over fruit quality in the selection 'Ovalado Grande', although the productive yield was maximized by the density of 3,200 plants ha -1 , the highest evaluated density.…”

“…There are several management alternatives aiming to optimize the passion fruit production; the high-density planting has been performed in several Brazilian regions, allowing the increase in the volume of productive branches per area, what may consequently provide an increase in production [3,4]. The planting density might be influenced by innumerable factors, such as the topography, the plant trellis system, the training and vigour of the plants and, especially, the edaphoclimatic conditions of the cultivation region [5,6].…”

Aims: The aim of this work was to evaluate the yield and the physical quality of the yellow passion fruit accession ‘Guinezinho’ as a function of the within-row plant spacing, with saline irrigation water in consecutive growing seasons. Study Design: The experiment was arranged in randomized blocks, with four replicates and 12 plants per parcel, in a 4 x 2 factorial arrangement, referring to the spacing in the planting lines of 3, 6, 9 and 12 m, and two consecutive growing seasons. Place and Duration of Study: The experiment was developed in the municipality of Coronel Ezequiel, Rio Grande do Norte state, Brazil, within the months of April 2013 and October 2014. Methodology: The seedings were transplanted in the spacings of 3, 6, 9 and 12 m, and distant 2 m within lines according to the treatments; they were conducted in a vertical shoot position (VSP) training system, and daily irrigated during the arid period with saline water (ECiw = 3.4 dS m-1). The following characteristics were evaluated: fruit yield, fruit mass, longitudinal and transversal fruit diameter, pulp yield, peel mass and peel thickness. Results: The interaction between spacing and growing season exercised a significant effect on the fruit yield, longitudinal fruit diameter, pulp yield, thickness and mass of the peel (P = .05). The variables transversal diameter and fruit mass only varied within the growing seasons (P = .05). The plants cultivated in the 3 m spacing were the most productive in the two seasons, with 23.7 and 36.3 t ha-1, in the first and second seasons, respectively. Conclusion: The highest yield of the yellow passion fruit accession ‘Guinezinho’ was obtained in the smaller plant spacing in the lines. Except for the pulp yield, the yield and physical quality of the fruits were superior in the second growing season. The irrigation with highly saline water, in this type of soil, did not compromise the productive ability of the passion fruit accession ‘Guinezinho’.

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.
