Title A name given to the resource Interação entre salinidade e bioestimulante na cultura do feijão caupi Interaction between water salinity and biostimulant in the cowpea plants Creator An entity primarily responsible for making the resource Francisco de A. de Oliveira, José F. de Medeiros, Mychelle K. T. de Oliveira, Antônia A. T. Souza, José A. Ferreira, Mateus S. Souza Description An account of the resource Objetivou-se, neste trabalho, avaliar a interação entre salinidade e o uso de bioestimulante (Stimulate®) sobre o desenvolvimento do feijão caupi. A semeadura foi feita em vasos utilizando-se, como substrato, um Argissolo Vermelho Amarelo. O experimento obedeceu a um delineamento inteiramente casualizado em esquema fatorial 2 x 7. Os tratamentos se constituíram da combinação de dois níveis de sais da água de irrigação e seis formas de aplicação de bioestimulante (Ausência, Tratamento de sementes, Foliar aos 20 dias após semeadura (DAS), Foliar aos 40 DAS, Tratamentos de sementes + Foliar aos 20 DAS, Tratamento de sementes + foliar aos 40 DAS e Aplicação foliar aos 20 e 40 DAS). Foram realizadas duas avaliações não destrutivas (20 e 40 DAS) e uma destrutiva (60 DAS) e avaliados a altura, o número de folhas, a área foliar e a massa seca de folhas, de caule e da parte aérea. Todos os parâmetros fisiológicos avaliados foram afetados pela salinidade. Nas formas de aplicação adotadas o bioestimulante não proporcionou melhorias no desenvolvimento das plantas quando submetidas ao estresse salino; a salinidade inibiu o efeito benéfico do bioestimulante sobre o desenvolvimento do feijão caupi; enfim, o uso de bioestimulante não é viável em plantas cultivadas sob estresse salino.The objective of this study was to evaluate the interaction between salinity levels of the water and the use of biostimulant (Stimulate®) in the initial development stage of cowpea plants. The sowing of seeds was done in pots, using as a substrate Alfissol and two plants per pot. The experimental design was completely randomized in a 2 x 7 factorial scheme. The treatments consisted of combination of two salinity levels (0.5 and 5.0 dS m-1) with seven biostimulant application forms (without application, seed treatment, sprinkled 20 days after sowing (DAS), sprinkled 40 DAS, seed treatment + sprinkled 20 DAS, seed treatment + sprinkled 40 DAS and sprinkled 20 and 40 DAS). Two non destructive evaluations (20 and 40 DAS) and one destructive evaluation (60 DAS) were performed. Plant height, number of leaves, leaf area, and dry mater of leaves, stem and aerial parts were evaluated. All parameters were influenced by salinity. The biostimulant in the adopted forms of application did not render any improvement on plant development when submitted to saline stress. The salinity inhibited the beneficial effects of the biostimulant on the growth of the cowpea plants therefore, the use of plant growth regulator is not feasible in plants grown under salt stress.
