Os tratamentos foram dispostos em delineamento em blocos casualizados usando arranjo fatorial 3 × 2, referente as doses de calcário de 1,4; 2,5 e 3,6 t ha-1, 80 e 160 kg ha-1 de K2O na forma de cloreto de potássio. Pelos resultados, a irrigação com água salina (3,6 dS m-1), em comparação com dados da literatura de plantas irrigadas com água de boa qualidade, não comprometeu a capacidade produtiva do maracujazeiro amarelo. Dentre os tratamentos, a combinação de 80 kg ha-1 de K2O com 3,6 t ha-1 de calcário calcítico proporcionou os maiores valores de massa média dos frutos, produção por planta e produtividade da cultura. Apesar da alta salinidade da água de irrigação elevar o caráter salino do solo no ambiente radicular das plantas durante o período da estiagem, as águas do período chuvoso e as condições físicas do solo proporcionam a lixiviação dos sais e possibilitam o uso de água com restrições salinas na agricultura.   Palavras-chave: Passiflora edulis, calagem, lixiviação de sais     CAVALCANTE, L.

YELLOW PASSION FRUIT PLANTS PRODUCTION ON SOIL WITH LIME AND POTASSIUM UNDER IRRIGATION WITH SALINE WATER       2 ABSTRACT   The experiment was carried out in Coronel Ezequiel county, Rio Grande do Norte, Brazil, in order to evaluate the effects of limestone and chloride potassium in production components of yellow passion fruit plants and soil salinity, caused by irrigation with saline water of 3.6 dS m-1 during the dry season, and salt leaching of the soil promoted by waters of the rainy season. Treatments were arranged in randomized blocks using factorial design of 3 × 2, referring to three levels of limestone,  1.4, 2.5 and 3.6 t ha-1 and two potassium levels,  80 and 160 kg ha-1 in potassium chloride form. According to present results, irrigation with saline water (3.6 dS m-1), in comparison with data from the literature about plants irrigated with non-saline water, did no compromise the productive capacity of yellow passion fruit. Among the treatments, the combination of 80 kg ha-1 of K2O with 3.6 t ha-1 of limestone provided the fruits production with more mean mass, yield per plant and crop yield. Although the high salinity of the irrigation water increases the soil saline character on root environment of the plants during the dry season, the rainy season waters and the soil physical conditions provide the salt leaching and allow the use of water with saline restrictions in agriculture.   Keywords: Passiflora edulis, liming, salt lixiviation

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

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.

Os tratamentos foram dispostos em blocos casualizados com três repetições e doze plantas por parcela. O plantio foi conduzido em sacos de polietileno com36 cm de diâmetro e60 cm de altura, acondicionando40 L do substrato. O crescimento avaliado pelo diâmetro do caule e número de ramos produtivos não foi influenciado pela salinidade da água e nem pela adição da matéria orgânica. Apesar da água salina e a adição de matéria orgânica interferir positivamente na emissão dos botões florais a produtividade foi muito baixa. A salinidade do substrato aumentou drasticamente com a salinidade das águas de irrigação e, em menor proporção, com o aumento da matéria orgânica adicionada. O maracujazeiro-amarelo foi mais sensível à salinidade na fase de produção que durante o crescimento inicial das plantas. UNITERMOS: salinidade do solo, irrigação, Passiflora edulis f. flavicarpa Deg, sistema de cultivo  CAVALCANTE, L.

The treatments were distributed in randomized blocks using three replications and twelve plants by plot. The planting was not carried out in traditional form of cultivation, but in mineral fertilizer bags with36 cm of diameter and60 cm of height using40 L of the substratum. The plants growth evaluated by stem diameter and emission of productive branches was not influenced by irrigation water salinity nor addition of organic matter to substratum. Although saline water and the organic matter had positive effects on floral buttons emission, they inhibited the productive capacity of plants. The yellow passion fruit plant was more sensitive to salt effects during the production phase than during its initial growth. KEYWORDS: soil salinity, irrigation, Passiflora edulis f. flavicarpa Deg, planting system.

ABSTRACT The objective of this study was to evaluate the gas exchange, growth and production of yellow passion fruit cv. BRS GA1, as a function of irrigation management strategies with saline water and potassium doses. The experiment was conducted under field conditions in São Domingos, PB, Brazil. A randomized block design was used in a 6 * 2 factorial scheme. The treatments consisted of six strategies of irrigation with saline waters (irrigation with low-salinity water throughout the crop cycle - SE; irrigation with high-salinity water in the vegetative stage - VE; flowering stage - FL; fruiting stage - FR; in the successive vegetative/flowering stages - VE/FL; vegetative/fruiting stages - VE/FR) and two doses of potassium (100 and 130% of the K2O recommendation), with four replicates and four plants per plot. The 100% dose corresponded to 60 g of K 2O plant-1 year-1. The effects of using high-salinity water (3.2 dS m-1) alternated with low-salinity water (1.3 dS m-1) were evaluated in different stages of the cultivation cycle. Irrigation with saline water in the fruiting stage promoted an increase in intercellular CO2 concentration and decrease in CO2 assimilation, with effects of non-stomatal origin standing out as limiting factors of photosynthetic efficiency. The highest CO 2 assimilation rate in plants subjected to water salinity of 1.3 dS m-1 throughout the cycle resulted in increments in the number of fruits and in the production per plant of the passion fruit cv. BRS GA1.

ABSTRACT An experiment was undertaken in Remígio County, Paraíba State, Brazil, from July 2013 to May 2014, in order to evaluate the effects of saline water irrigation, bovine biofertilizer, and potassium type on soil salinity, leaf macronutrient composition, and production of yellow passion fruit cv. BRS Gigante Amarelo. Treatments were distributed in randomized blocks, arranged in a 2 × 2 × 2 factorial design, with reference to electrical conductivity of the water (0.35 and 4.00 dS m-1), soil with and without bovine biofertilizer, and application of potassium chloride as a conventional treatment (KCl) and in an organic polymer-coated form, supplied monthly. Bovine biofertilizer was diluted in non-saline water (proportion, 50%) and applied via water at a volume of 6 L plant-1 one day before transplanting, and then every 90 days. The combination of saline water with bovine biofertilizer raised soil salinity to a similar proportion when comparing saline water and conventional potassium chloride with saline water and polymer-coated potassium chloride. The increase in water saline concentrations associated with both types of potassium chloride and with bovine biofertilizer elevated soil salinity from non-saline to saline. On starting to flower, plants of cv. BRS Gigante Amarelo were deficient in macronutrients other than nitrogen and potassium, but nonetheless produced fruits of an adequate mass for the consumer market.
