Com isso, visando melhorar à aclimatação das plantas ao estresse salino, diversas estratégias de manejo são estudadas, principalmente aquelas com potencial de melhorar a absorção e assimilação de nutrientes. Nesse contexto, a presente pesquisa teve como objetivo estudar os efeitos dos íons nitrato e amônio na atenuação do estresse salino em plantas de abobrinha italiana (cv Caserta) cultivadas em sistema hidropônico. O experimento foi conduzido em casa de vegetação, em delineamento experimental de blocos casualisados, arranjados em esquema fatorial 2 x 5, com 4 repetições. Os tratamentos foram constituídos de duas formas específicas de nitrogênio (nitrato - NO3- e amônio - NH4+) e cinco níveis de condutividade elétrica da água de irrigação (CEa) (0,5; 2,0; 3,5; 5,0 e 6,5 dS m-1). As plantas foram cultivadas até a fase de produção em vasos com capacidade para 8 dm3, preenchidos com substrato a base de fibra de coco. Avaliou-se as plantas quanto ao crescimento, trocas gasosas, fluorescência da clorofila a, pigmentos cloroplastídicos, percentagem de dano celular nas folhas, composição mineral da parte aérea e produção. Os resultados foram avaliados por meio de análise de variância, verificando-se as significâncias ao nível de 5% de probabilidade dos tratamentos por meio do teste F. Os resultados indicaram que a nutrição exclusiva com nitrogênio na forma de NH4+ promove redução no crescimento e acúmulo de biomassa das plantas de abobrinha italiana. Essas plantas apresentam maiores restrições na eficiência fotoquímica e fotossintética do que as nutridas com NO3- quando crescidas sob condição de salinidade. Além disso, apresentam morte prematura na fase de floração, independente da condição de estresse salino. A nutrição com nitrogênio na forma de NO3- é indicada para o cultivo hidropônico da abobrinha italiana. A irrigação com água de condutividade elétrica superior a 2,0 dS m-1 reduz o crescimento, as trocas gasosas, a eficiência fotoquímica e não fotoquímica, o acúmulo de nutrientes na parte aérea das plantas e a produção de abobrinha italiana. Sugere-se a realização de outras pesquisas semelhantes para aprofundar os conhecimentos sob o possível potencial dos íons NO3- e NH4+ na atenuação dos efeitos da salinidade em plantas de abobrinha italiana e outras cucurbitáceas Salt stress is one of the most restrictive abiotic factors in plant growth and yield in the world, especially in arid and semi-arid zones. In order to improve the acclimatization of plants to salt stress, several management strategies are studied, especially those with potential to improve the absorption and assimilation of nutrients. In this context, the present research aimed to study the effects of nitrate and ammonium ions on the attenuation of salt stress in zucchini plants (Caserta cv.) grown in a hydroponic system. The experiment was carried out in a greenhouse, in an experimental design of randomized blocks, arranged in a 2 x 5 factorial scheme, with 4 replications. The treatments consisted of two specific forms of nitrogen (nitrate - NO3- and ammonium - NH4+) and five levels of electrical conductivity of the irrigation water (ECw) (0.5, 2.0, 3.5, 5.0 e 6.5 dS m-1). The plants were grown until the production phase in pots with capacity of 8 dm3, filled with coconut fiber-based substrate. The plants were evaluated for growth, gas exchange, chlorophyll a fluorescence, chloroplastidic pigments, percentage of leaf cell damage, aerial shoot composition and yield. The results were analyzed through analysis of variance, with significance being verified at the 5% probability level of the treatments using the F test. The results indicated that the exclusive nutrition with nitrogen in the form of NH4+ promotes reduction in the growth and accumulation of biomass of Italian zucchini plants. These plants present greater restrictions in the photochemical and photosynthetic efficiency than those fed with NO3- when grown under salinity conditions. In addition, they present premature death in the flowering phase, regardless of the saline stress condition. Nitrogen nutrition in the form of NO3- is indicated for the hydroponic cultivation of zucchini. Irrigation with water of electrical conductivity higher than 2.0 dS m-1 reduces growth, gas exchange, photochemical and non-photochemical efficiency, nutrient accumulation in the aerial part of plants and production of Italian zucchini. It is suggested to carry out other similar researches to deepen the knowledge under the possible potential of NO3- and NH4+ ions in the attenuation of salinity effects in zucchini and other cucurbit plants

Abstract

The objective of this work was to evaluate the soil quality in areas of Caatinga under different management systems, with soil physical attributes as parameters. The forms of management adopted were: (1) area of sustainable management of Caatinga; (2) area of conventional management; and (3) native forest area. After 5 years, soil samples were collected in the areas at depths 0.00-0.20 m and 0.20-0.40 m for analysis of soil physical attributes. The results evidenced greater soil compaction in the area of conventional management. The sustainable management of Caatinga proved to be a promising technique for maintaining and recovering the soil physical properties. Objetivou-se avaliar a qualidade do solo, em áreas da Caatinga submetidas a diferentes sistemas de manejo, tendo como parâmetros os atributos físicos do solo. As formas de manejo adotadas foram: (1) área de manejo sustentável da Caatinga; (2) área de Caatinga com manejo convencional; e (3) área de Caatinga considerada mata nativa. Decorridos 5 anos, foram coletadas amostras de solo nas áreas nas profundidades 0,00-0,20 m e 0,20-0,40 m para análise dos atributos físicos do solo. Os resultados evidenciaram maior compactação do solo na área de manejo convencional. O manejo sustentável da Caatinga mostrou-se uma técnica promissora para manutenção e recuperação das propriedades físicas do solo.
