A produção de mudas é uma das etapas mais importantes em sistemas produtivos de frutos, sendo a sua boa nutrição mineral um dos atributos que podem resultar em bom índice de qualidade. Objetivou-se avaliar a concentração e os acúmulos de macronutrientes e sódio em mudas de maracujazeiros produzidas com aplicação de urina de vaca e águas salinas. O experimento foi conduzido, em estufa de cobertura plástica, no Instituto Federal da Paraíba – campus Picuí, em delineamento experimental inteiramente casualizado, no arranjo fatorial 2×2×2, correspondente a duas espécies de maracujazeiro (amarelo e roxo), dois níveis de condutividade elétrica da água de irrigação (0,5 dS m-1 e 3,5 dS m-1) e aplicação de urina oxidada de vaca a 0,0% e 5,0% e três repetições. Foram analisados os teores e os acúmulos de macronutrientes foliares (N, P, K+, Ca2+, Mg2+ e S) e sódio. A irrigação com águas salinas de até 3,5 dS m-1 produz efeitos negativos nos teores de P e Na+ e positivos na concentração de N, Ma2+ nos tecidos foliares de mudas de maracujazeiros amarelo e roxo. Os teores foliares de N, Mg2+ e Na+ em mudas de maracujazeiro-amarelo são superiores aos de maracujazeiro-roxo A aplicação de urina oxidada de vaca diluída em água a 5,0% na produção de mudas de maracujazeiros amarelo e roxo irrigadas com águas de elevada salinidade, por apresentar efeitos negativos nos teores de K+ nos tecidos foliares, indica que o insumo pode não eliminar os efeitos dos sais às plantas na fase de mudas. O uso de urina oxidada de vaca afeta, positivamente, os teores foliares de N em mudas de maracujazeiros. O acúmulo de macronutrientes (P, K+ e Ca2+) em folhas de mudas de maracujazeiros é maior quando irrigadas com águas de baixa salinidade.Palavras-chave: Passiflora spp; estresse salino; nutrição de plantas. NUTRIENTS CONTENTS AND ACCUMULATIONS IN PASSION FRUIT SEEDLINGS UNDER WATER SALINITY AND USE OF COW URINE ABSTRACT:Seedling production is one of the most important stages in fruit production systems, and its good mineral nutrition is one of the attributes that can result in a good quality index. The objective was to evaluate the concentration and accumulations of macronutrients and sodium in passion fruit seedlings produced with the application of cow urine and saline water. The experiment was carried out in a plastic-covered greenhouse at the Federal Institute of Paraíba - Picuí campus, Brazil, in a completely randomized experimental design, in a 2 × 2 × 2 factorial arrangement, corresponding to two species of passion fruit (yellow and purple), two levels of electrical conductivity of irrigation water (0.5 dS m-1 and 3.5 dS m-1) and application of oxidized cow urine at 0.0% and 5.0% and three repetitions. The levels and accumulations of leaf macronutrients (N, P, K+, Ca2+, Mg2+ and S) and sodium were analyzed. Irrigation with saline water up to 3.5 dS m-1 produces negative effects on the levels of P and Na+ and positive on the concentration of N, Ma2+ in the leaf tissues of yellow and purple passion fruit seedlings. The leaf contents of N, Mg2+ and Na+ in yellow passion fruit seedlings are higher than those of purple passion fruit. The application of oxidized cow urine diluted in 5.0% water in the production of yellow and purple passion fruit seedlings irrigated with water high salinity, due to its negative effects on K+ content in leaf tissues, indicates that the input may not eliminate the effects of salts on plants in the seedling phase. The use of oxidized cow urine positively affects leaf N levels in passion fruit seedlings. The accumulation of macronutrients (P, K+ and Ca2+) in leaves of passion fruit seedlings is greater when irrigated with low salinity water.Keywords: Passiflora spp; salt stress; plant nutrition.

In plants sensitive to salinity, such as passion fruit, irrigation with saline water can cause physiological disturbances and reduce fruit production, necessitating the use of cultural practices that mitigate saline stress. The objective of this study was to evaluate the effects of water salinity, pit coating with high-strength polyethylene film, and calcium fertilization on the physiological and productive aspects of passion fruit ‘BRS Gigante Amarelo’. The treatments were arranged in split plot in the scheme 2WS × (2LP × 5DC), corresponding to water salinity (0.3 and 4.0 dS m-1) as the main plot, side coating of pits (without and with) doses of calcium (0; 30; 60; 90 and 120 kg ha-1). During the flowering phase, we evaluated leaf chlorophyll indices, fluorescence kinetics, and gas exchange. The increase in calcium doses up to 60 kg ha-1 increased leaf chlorophyll and quantum efficiency. The stomata did not restrict gas exchange, but salinity resulted in reduced net photosynthesis and plant production. The lateral coating of the pits intensified the reduction in salinity-promoted production, while calcium mitigated the effects of the salts. Entisol cultivated with passion fruit should not be irrigated with saline water of 4.0 dS m-1; lateral pit coating is not advised. In an Entisol with an initial calcium level of 1.92 cmolc dm-3, the recommended application dose is 60 kg ha-1 for passion fruit cultivation.

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 In a scenario of water scarcity in semiarid regions, it is imperative to design food production systems that use different sources of water. The waste of desaltersis a potential source, especially when combined with the hydroponics technique that includes the supply of nutrient solution as a source of water and nutrients. In addition, other techniques such as enhanced organic matter with biofertilizer can complement this low-quality water use strategy. Thus, the aim of this study was to analyze the possible dampening effect of biofertilizers in the open system of hydroponic culture of pepper owing to the increase in water salinity. The study was conducted at the Teaching Unit, Research and Extension, Federal Institute of Education, Science and Technology of Ceará, Limoeiro do Norte Campus. The experimental design was a factorial 5 × 4 randomized block for five saline water concentration sand three doses of biofertilizers and one control with mineral fertilizer, and four replicates totaling 80 experimental units with 3 plants per plot. The variables analyzed were number of fruits per plant, production, and length and width of the fruit. All production variables declined linearly with increasing salinity. In addition, the biofertilizer did not attenuate the deleterious effects of salinity as shown by the productivity data. The fertilization with mineral fertilizers produced greater yields, followed by application of 50%, 100%, and 150% of the biofertilizer dose.

The experiment was conducted in the city of Remigio, Paraiba State, Brazil, from July/2013 to May/2014. The aim of this work is to evaluate the effects of the saline water, bovine biofertilizer and potassium source on soil salinity, micronutrients and sodium contents in the leaf dry matter, and on the production of yellow passion fruit plants cv BRS Gigante Amarelo. The treatments were distributed in randomized blocks subdivided into plots using the factorial scheme 2 × (2 × 2). It refers to the main plot as two different irrigation waters with electrical conductivities of 0.35 and 4.00 dS m-1, and the subplots as the combination between the biofertilizer application and exemption with different potassium sources: the conventional potassium chloride (KCl) and the polymer-coated one. The increase in the electrical conductivity of the irrigation water increased the initial soil salinity from 0.36 to 3.43 and after to 5.43 dS m-1. It also increased the leaf contents of Fe2+ and Na+. The biofertilizer increased the Zn2+ content in the leaf dry matter of the passion fruit plants, while the fertilization with polymer-coated KCl increased the B content and reduced the Mn2+ one as compared to the conventional KCl. The plants, at the beginning of the flowering phase, although their deficiencies of all micronutrients, presented satisfactory productivity levels whether the national average numbers are considered.

Passion fruit (Passiflora edulis Sims.) is an ever-increasing interest crop in Italy because it is mainly cultivated for its edible fruit and, secondly, as an ornamental evergreen climber. During the summer of 2020, two-year-old plants of purple passion fruit in one of the most important expanding production areas of Sicily (southern Italy) showed symptoms of yellowing, wilting, and vascular discoloration. Fusarium-like fungal colonies were consistently yielded from symptomatic crown and stem tissues. Five representative isolates were characterized by a morphological and molecular analysis based on a multilocus phylogeny using RNA polymerase’s second largest subunit (RPB2) and translation elongation factor 1-alpha (EF-1α) genes, as Fusarium nirenbergiae (Fusarium oxysporum species complex). Pathogenicity tests conducted on healthy 1-year-old passion fruit cuttings revealed symptoms similar to those observed in the field. To our knowledge, this is the first report of Fusarium wilt on passion fruit caused by Fusarium nirenbergiae. This report focuses on the phytopathological implications of this fungal pathogen, which may represent a future significant threat for the expanding passion fruit production in Italy and Europe.

Plant viruses may pose a threat to crops in Colombia. To evaluate the potential risk of yield losses due to plant virus infection, a literature analysis followed by a first field study was carried out focusing on purple passion fruit (Passiflora edulis Sims), cape gooseberry (Physalis peruviana L.), and ornamental rose (Rosa sp.), which are important Colombian exports. Over the past three years, plant material was collected from 21 farms in Cundinamarca and Boyacá, Colombia, two regions that are in close proximity to El Dorado International Airport, the country’s largest air freight terminal. Plants were visually inspected and subsequently tested by bioassay and serological methods. Overall, in the samples investigated by the two diagnostic methods, plant viruses were detected. Detected viruses belong to the genus Poty-, Tobamo-, Nepo-, Ilar-, and Tospovirus. The extent of the distribution and occurrence of these viruses in each crop has to be determined in a representative field study. Such a monitoring program could be supported by a standardized farmer interview. The development of suitable plant virus diagnostic and managements tools is the focus of a cooperation project between German and Colombian universities, the Colombian Agricultural Institute (ICA), the Colombian Corporation of Agricultural Investigation (AGROSAVIA) and the International Center for Tropical Agriculture (CIAT).

Hydrophobic Particle

Hydrophobic particle film technology (HPF) is a developing pest control system for tree fruit production systems. Studies were established in Chile, and Washington, Pennsylvania, and West Virginia in the United States, to evaluate the effect of HPF technology on tree fruit yield and quality. Studies in Chile, Washington, and West Virginia demonstrated increased photosynthetic rate at the leaf level. Yield was increased in peaches (Chile) and apples (West Virginia), and fruit size was increased in apples (Washington and Pennsylvania). Increased red color in apple was demonstrated at all sites with reduced russetting and `Stayman' cracking in Pennsylvania. HPF technology appears to be an effective tool in reducing water and heat stress in tree fruit resulting in increased fruit quality.
