“…For these authors, the toxic effects of the mixture of salts on plants and specific ions such as Na + , Cl -, SO 4 2-and NO 3-causes nutrient imbalance and physiological impairment to the plants (CHEN et al, 2010;DIAS;BLANCO, 2010). (Figure 7).…”

“…However, due to the nitrogen sources being commercialised in the form of salts, according to the potential of the mineral input in reducing the osmotic pressure of the soil solution in comparison to the sodium nitrate, which is the standard fertiliser for salinity studies (SILVA; BORGES, 2009). The fertiliser, instead of mitigating, may increase the soil saline concentration, especially when applied together with irrigation water (CHEN et al, 2010), causing morphophysiological and yield losses, mainly for salt sensitive plants.…”

The lack of good quality water for agriculture purposes regarding salts and quantity in relation to demand for the plants has, for more than 30 years, been forcing the use of restrictive water because of salinity issues in agricultural production systems worldwide. In Brazil, the situation is no different, in the semi-arid areas, there are reports of losses of seed germination, initial growth of seedlings and yield of crops of commercial importance due to the salinity of the water used in irrigation systems. Therefore, an experiment was carried out from June to September/2014 in a protected environment, with a plastic film on the upper base and a thin screen against insects on the sides, to evaluate the effects of salinity interaction between water irrigation and nitrogen fertilisation sources on soil salinity, initial plant growth and the quality of the jackfruit seedlings. The treatments were distributed in randomised blocks, in the factorial scheme 5 × 3, reference irrigation water of 0.3, 1.0, 2.0, 3.0 and 4.0 dS m -1 , in soil with and without ammonium sulfate and urea. An increase in the salinity of the irrigation water to 1.32 and 1.70 dS m -1 on the substrate without nitrogen stimulated an increase in the number of leaves and leaf area of the jackfruit seedlings. The ammonium sulfate was the nitrogen source that mainly contributed to the increase of soil salinity and to the reduction of the quality index of the seedlings. Despite the reduction of the Dickson quality index due to the salinity of the irrigation water and the nitrogen sources, the seedlings were suitable for cultivation. Key words: Artocarpus heterophyllus, water salinity, nitrogen fertilisers. ResumoA falta de água de boa qualidade para fins agrícola em relação aos sais e quantidade em relação à demanda pelas plantas tem, há mais de 30 anos, forçado o uso de água restritiva por problemas de salinidade em sistemas de produção agrícola em todo o mundo. No Brasil, a situação não é diferente; nas áreas semiáridas, há relatos de perdas de germinação de sementes, crescimento inicial de mudas e rendimento de culturas de importância comercial devido à salinidade da água utilizada em sistemas de irrigação. Assim, foi realizado um experimento de junho a setembro de 2014 em ambiente protegido, com filme plástico na base superior e tela fina nas laterais contra insetos, para avaliar os efeitos da interação salinidade entre irrigação e fontes de fertilização nitrogenada na salinidade do solo, crescimento inicial da planta e qualidade das mudas de jaqueira. Os tratamentos foram distribuídos em blocos casualizados, no esquema fatorial 5 × 3, referente às água de irrigação de 0,3; 1,0; 2,0; 3,0 e 4,0 dS m -1 , em solo com e sem sulfato de amônio e ureia. O aumento na salinidade da água de irrigação para 1,32 e 1,70 dS m -1 no substrato sem nitrogênio estimulou aumento no número de folhas e área foliar das plântulas de jaqueira. O sulfato de amônio foi à fonte de nitrogênio que mais contribuiu para o aumento da salinidade do solo e para a redução ...

“…Surface water used for irrigation comes from the Kongque River, whose water quality is affected by nearby Bosten Lake and has electrical conductivity (EC) values generally between 0.9 and 1.6 dS/m . Groundwater, having EC values between about 3-5 dS/m (see Table 1), is used often also for irrigation of cotton, which is known to have a relatively high tolerance for salinity (Maas 1990;Vulkan-Levy et al 1998;Henggeler 2004;Steppuhn et al 2005;Chen et al 2010). The sodium adsorption ratio (SAR) of irrigation water ranged from 3.77 to 9.97.…”

“…Mulched drip irrigation, which saves water and increases water use efficiency as compared to furrow irrigation (Ibraginmov et al 2007), is widely used in the area to irrigate cotton, a major cash crop in Xinjiang (Hou et al 2009). Cotton yields generally decrease with a reduction in irrigation, irrespective of whether conventional irrigation technologies or drip irrigation is used (Singh et al 2010;Ü nlü et al 2011), and are also limited by poor quality of irrigation water and related problems of soil salinization (Leidi and Saiz 1997;Vulkan-Levy et al 1998;Qadir and Shams 1997;Henggeler 2004;Chen et al 2010).…”

Evaluation of mulched drip irrigation for cotton in arid Northwest China

Field experiments were conducted in arid Southern Xinjiang, Northwest China, for 3 years to evaluate sustainable irrigation regimes for cotton. The experiments involved mulched drip irrigation during the growing season and flood irrigation afterward. The drip irrigation experiments included control experiments, experiments with deficit irrigation during one crop growth stage, and alternative irrigation schemes in which freshwater was used during one growth stage and relatively saline water in the others. The average cotton yield over 3 years varied between 3,575 and 5,095 kg/ha, and the irrigation water productivity between 0.91 and 1.16 kg/m 3 . Crop sensitivities to water stress during the different growth stages ranged from early flowering-belling (most sensitive) [ seedling [ budding [ late flowering-belling (least sensitive), while sensitivities to salt stress ranged from late flowering-belling [ budding [ seedling [ early flowering-belling. Although mulched drip irrigation during the growing season caused an increase in salinity in the root zone, flood irrigation after harvesting leached the accumulated salts to below background levels. Numerical simulations, based on the 3-year experiments and extended by another 20 years, suggest that mulched drip irrigation using alternatively fresh and brackish water during the growing season and flood irrigation with freshwater after harvesting is a sustainable irrigation practice that should not lead to soil salinization.

“…Embora a interação salinidade x nutrição mineral seja complexa, tem-se constatado que a adubação nitrogenada provoca efeitos positivos na redução dos danos da salinidade às culturas (Barhoumi et al, 2010;Chen et al, 2010) e que as propriedades texturais, quando a vegetação e topografia se mantêm constantes, podem afetar o conteúdo de nitrogênio no solo (Stevenson, 1982). Assim, este trabalho objetivou avaliar os efeitos da salinidade da água de irrigação nas trocas gasosas da cultura do milho sob adubação nitrogenada, cultivado em colunas de solo com texturas diferentes.…”

RESUMO:A adubação nitrogenada provoca efeitos positivos na redução dos danos da salinidade às culturas e a textura do solo pode afetar a dinâmica do nitrogênio na rizosfera.Assim, este trabalho objetivou avaliar os efeitos da salinidade da água de irrigação nas trocas gasosas da cultura do milho sob adubação nitrogenada, cultivado em colunas de solo com texturas diferentes. Foi empregado o DIC com fatorial 2x2x4: solos (Argissolo e Neossolo); doses de nitrogênio (210 kg ha -1 e 105 kg ha -1 ) e salinidade da água de irrigação (0,5, 2, 4 e 6 dS m -1 ), com quatro repetições. Avaliou-se a condutância estomática (gs) e concentração interna de CO2 (Ci). Plantas cultivadas em Argissolo apresentaram maior gs e Ci em comparação ao Neossolo. As doses de nitrogênio foram significativas apenas para a gs, onde a dose de 210 kg ha -1 mostrou a melhor resposta. Ocorreu uma diminuição da gs e Ci decorrente do incremento da salinidade da água de irrigação, sendo a redução da gs mais acentuada no Argissolo. Com isso, constata-se que a salinidade da água de irrigação reduz as trocas gasosas foliares da cultura do milho, as quais são potencializadas nos solos de textura mais argilosas como no Argissolo. PALAVRAS-CHAVE: Estresse salino, nitrogênio, trocas gasosas foliares EFFECTS OF SALINITY AND NITROGEN FERTILIZATION ON STOMATAL CONDUCTANCE AND INTERNAL CO 2 CONCENTRATION IN MAIZE ABSTRACT:The nitrogen fertilization provokes positive effects in the reduction of crop salinity damage and the soil texture can affect the nitrogen dynamics in the rhizosphere. Thus, this work aimed to evaluate the effects of salinity of irrigation water on the leaf gas exchange
