description Background and aims: A large volume of vinasse is generated annually in Argentinean ethanol producing provinces. It has been proposed that vinasses could be used for sugarcane or soybean fertigation. However, basic research to know the effect of vinasse on soil, morphology and crop physiology is scarce in the Argentine northwest. M&M: We provide data on the effect of diluted vinasse (1:1, 1:5 and 1:10 v/v) on photosynthetic CO2 assimilation in soybean plants grown under semicontrolled conditions (greenhouse). Results: Maximum photosynthetic assimilation rate (Amax) was strongly affected by all vinasse dilutions. In the lowest dilution (1:1) the Amax decreased 35% while in highest dilution (1:10) a 15.9% decrease was observed. Changes in Amax were correlated with decreases in stomatal conductance, leaf nitrogen content (Nf) and total chlorophyll. Data of chlorophyll fluorescence show a decrease in Fv/Fm at 1:1 dilution, which indicate a photosystem II (PSII) stress. Conclusions: We can conclude that the application of diluted vinasse affects gas exchange parameters and if it is used it should be done with dilutions 1:10 or higher. Long-term studies are essential to know the effect of vinasse on physicochemical and biological characteristics of soils as well as the probable accumulation of heavy metals in fertirrigated plants.

Introducción y Objetivos: En las provincias argentinas productoras de alcohol se genera anualmente un gran volumen de vinazas. Se ha propuesto que las mismas podrían ser utilizada para el fertirriego de la caña de azúcar u otras especies. Sin embargo, las investigaciones básicas para conocer el efecto de las mismas sobre el suelo, morfología y fisiología de las especies a fertirrigar son escasas en el noroeste argentino. M&M: Se aportan datos sobre el efecto de la vinaza diluida (1:1, 1:5 y 1:10 v/v) sobre la asimilación fotosintética de soja cultivada bajo condiciones semicontroladas (invernáculo). Resultados: La asimilación fotosintética máxima (Amax) se afecta fuertemente en todas las diluciones utilizadas. En la menor dilución (1:1) la Amax disminuye el 35 % respecto al control, mientras que en la dilución 1:10 dicho porcentaje se reduce al 15,9 %. Los cambios en la Amax se correlacionaron con disminuciones en la conductancia estomática, contenido de nitrógeno foliar (Nf) y clorofila total. Los datos de fluorescencia de la clorofila muestran una disminución de Fv/Fm en la dilución 1:1, lo que indicaría un estrés en el fotosistema II (PSII) inducido por la vinaza. Conclusiones: Se concluye que la aplicación de vinaza diluida, afecta el intercambio de gases y que si se la utiliza debería hacerse con diluciones 1:10 o superiores. Se recomienda estudios a largo plazo para conocer el efecto de la vinaza sobre las características fisicoquímicas y biológicas de los suelos, así como la probable acumulación de metales pesados en las plantas fertirrigadas.
