| Um experimento foi desenvolvido em ambiente telado do Departamento de Solos e Engenharia Rural da Universidade Federal da Paraíba, Areia, PB, no período de janeiro a abril de 2010. O substrato constou de material de um Neossolo Quartzarênico não salino, coletado na camada de 0-20 cm. Os tratamentos foram dispostos em delineamento inteiramente casualizado em esquema fatorial 5 x 2, referente aos níveis de salinidade da água de irrigação de 0,5; 1,0; 2,0; 3,0 e 4,0 dS m-1, no solo sem e com biofertilizante comum, aplicado ao solo uma única vez, após diluição em água, na proporção de 1:1, um dia antes da semeadura, em volume correspondente a 10% do volume do substrato. Aos 86 dias após a emergência das plântulas normais avaliaram-se o crescimento em altura e... |

| 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... |

| Abstract The salinity of irrigation water can affect the growth and development of most plants of commercial interest. Aiming to study these aspects in passion fruit culture, an experiment was performed to evaluate the effects of bovine biofertilizer and potassium fertilization on gas exchange and production of the passion fruit ‘BRS Giant Yellow’ irrigated with non-saline and saline water. The treatments were arranged in randomized blocks with sub-subdivided plots using the 2×(3×5) scheme, which refers to two levels of electrical conductivity of the irrigation water as the main plot (0.35 and 4.00 dS m−1) and the combination of three potassic fertilization practices (without fertilization, fertilized with conventional and... |

| ABSTRACTThe response of plants to salt stress is an extremely complex phenomenon that involves morphological, physiological and biochemical changes, modifying the leaf contents of chlorophyll and carotenoids, among others and affecting plant growth, development and production. An experiment was carried out from July 2010 to June 2011, in order to evaluate the contents of chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, the chlorophyll a/b ratio and biomass accumulation of shoots and roots of noni plants, when subjected to irrigation and leaching with water of increasing salinity. The experiment was carried out in a greenhouse, at the Center of Agricultural Sciences of the Federal University of Paraíba, in the municipality of Areia-PB, Brazil.... |
