“…Em estudo de dez anos, com uso de dois tipos de água salina para a irrigação da cana-de-açúcar, Choudhary et al (2004) observaram redução no açúcar da cana no primeiro ano de avaliação, o que exigiu o uso de condicionadores para a manutenção da qualidade da cana. Os dois tipos de água utilizados no experimento desses autores, no entanto, possuíam salinidade maior (1,43 e 2,9 dS m -1 ) do que a observada no efluente utilizado no presente trabalho.…”

Resumo -O objetivo deste trabalho foi avaliar o desempenho produtivo e qualitativo da cana-de-açúcar (Saccharum spp.), irrigada por gotejamento subsuperficial com efluente de estação de tratamento de esgoto (EETE). Testaram-se lâminas de irrigação entre 0, na testemunha sem irrigação, e 200% da evapotranspiração máxima da cultura, em dois ciclos de cultivo de cana soca, adubada com metade da quantidade recomendada de nitrogênio (N). A produtividade, em cada ciclo, foi ajustada a um modelo que considera a produtividade da cana planta como covariável. Por esse modelo, os ganhos em produtividade, proporcionados pela reposição da evapotranspiração com EETE, foram de 17,13 e 25,76 Mg ha -1 . A aplicação de 200% de EETE resultou no ganho estimado de 19,84 Mg ha -1 na primeira soca e 40,47 Mg ha -1 na segunda. Houve redução de sólidos solúveis do caldo da cana, com o uso da irrigação na primeira soca. No entanto, outros parâmetros indicativos da qualidade industrial não foram significativamente alterados pela irrigação. A irrigação com EETE proporciona ganhos de produtividade da cana-de-açúcar e reduz a adubação nitrogenada recomendada no cultivo da primeira e segunda socas.Termos para indexação: Saccharum, adubação nitrogenada, gotejamento subterrâneo, reuso de água. Sugarcane yield and quality under irrigation with sewage treatment plant effluentAbstract -The objective of this work was to evaluate the productive and qualitative performance of sugarcane (Saccharum spp.) irrigated by subsurface chip irrigation with sewage treatment plant effluent (STPE). Irrigation depths were tested between 0% (control, without irrigation) and 200% of crop maximum evapotranspiration, in two ratoon cycles fertilized with half the recommended amount of nitrogen (N). The productivity, in each cycle, was fitted to a model which considers the plant yield as covariable. By this model, productivity gains provided by the replacement of crop evapotranspiration by the irrigation with STPE were: 17.3 and 25.76 Mg ha -1 . The 200% STPE application resulted in a estimated gain of 19.84 Mg ha -1 at the fisrt ratoon cycle and of 40.47 Mg ha -1 at the second. Soluble solids were reduced in sugarcane juice with the irrigation use in the first ratoon cycle. However, other industrial quality parameters were not significantly affected by irrigation. The irrigation with STPE promotes sugarcane productivity and reduces the N fertilization requirement of the first and second ratoon cycle.

“…The physical, chemical and biological properties of soil in salt-affected areas are improved by the application of OM, leading to enhanced plant growth and development. Therefore, the application of OM for soil remediation is important for sustainable land use and crop productivity (Choudhary et al, 2004;Wong et al, 2009).…”

Soil salinity may limit plant growth and development, and cause yield loss in crop species. This study aimed at remediating saline soil using organic matter (OM) treatment, before the cultivation of RD6 rice (Oryza sativa L. spp. indica). Physiological and morphological characters of rice plants, as well as crop yield, were evaluated from salt-affected soil with varying levels of salinity. The chlorophyll a and total chlorophyll pigments of rice plants grown in salt-affected soil (2% salt level) with the application of OM were maintained better than in plants grown without OM treatment. The degree of reduced photosynthetic pigments in rice plants was dependent on the level of salt contamination. Pigment content was positively related to maximum quantum yield of PSII (F v /F m ) and quantum efficiency of PSII (Φ PSII ), leading to reduced net photosynthetic rate (P n ) and reduced total grain weight (TGW). Photosynthetic abilities, including chlorophyll a and total chlorophyll pigments and Φ PSII , in rice plants grown with OM treatment were greater than in those cultivated in soil without the OM treatment, especially in high salt levels (1-2% salt). The remediation of salt-affected soil in paddy fields using OM should be applied further, as an effective way of enhancing food crop productivity.

“…Several methods have been proposed to reclaim salt-affected soils. The physical, chemical and biological properties of soil in salt-affected areas are improved by the application of organic matter, leading to enhanced plant growth and development, therefore, the application of organic matter for soil remediation is important for sustainable land use and crop productivity (Choudhary et al, 2004). Keeping in view the importance of organic amendments on the reclamation of salt affected soils, a leaching study was carried out by using locally available organic amendments to study the impact of sole and combined use of organic amendments with leaching on soil salinity and soil nitrate content in saline soils.…”
