Resumo: Agriculture is the main economic activity responsible for the highest rates of water consumption worldwide. Understanding strategies that combine decreasing the amount of water available and reducing the addition of chemical fertilizers is a major challenge today. Within this context, the work aimed to evaluate the efficiency in promoting growth in tomato seedlings, inoculated with Serratia nematodiphila, submitted to different water deficit conditions. The methodology consisted of using tomato seeds cv. Santa Clara Miss Brasil previously disinfected and inoculated with the Serratia nematodiphila bacterium. The experimental design was completely randomized in the factorial scheme 2 (with bacteria and without bacteria) x 3 (irrigation levels: 100%, 50% and 25% water), making a total of 6 treatments with 6 repetitions. When evaluating the effect of the bacteria Serratia nematodiphila in the treatment with irrigation to 25% of water, it was observed that the average values ​​of the root length of the tomato seedlings was the one that suffered the most stimulus in the root growth when compared to the other irrigation levels. These results suggest that under conditions of greater water deficit the bacteria is able to mitigate drought by promoting root growth.

Comprender las estrategias que combinan la disminución de la cantidad de agua disponible y la reducción de la adición de fertilizantes químicos es un desafío importante hoy en día. En este contexto, el trabajo tuvo como objetivo evaluar la eficiencia en la promoción del crecimiento de las plántulas de tomate, inoculadas con Serratia nematodiphila, sometidas a diferentes condiciones de déficit hídrico. La metodología consistió en utilizar semillas de tomate cv. Santa Clara Miss Brasil previamente desinfectada e inoculada con la bacteria Serratia nematodiphila. El diseño experimental fue completamente al azar en el esquema factorial 2 (con bacterias y sin bacterias) x 3 (niveles de riego: 100%, 50% y 25% de agua), haciendo un total de 6 tratamientos con 6 repeticiones. Al evaluar el efecto de la bacteria Serratia nematodiphila en el tratamiento con riego al 25% del agua, se observó que los valores promedio de la longitud de la raíz de las plántulas de tomate fueron los que sufrieron el mayor estímulo en el crecimiento de la raíz en comparación con los otros niveles de riego. Estos resultados sugieren que, en condiciones de mayor déficit hídrico, la bacteria puede mitigar la sequía al promover el crecimiento de las raíces.A agricultura é a principal atividade econômica responsável pelos maiores índices de consumo de água em todo o mundo.

Dentro desse contexto, o trabalho teve por objetivo avaliar a eficiência na promoção de crescimento em plântulas de tomate, inoculadas com Serratia nematodiphila, submetidas a diferentes condições de déficit hídrico. A metodologia consistiu em utilizar sementes de tomate cv. Santa Clara Miss Brasil previamente desinfestadas e inoculadas com a bactéria Serratia nematodiphila. O design experimental foi inteiramente casualizado no esquema fatorial 2 (com bactéria e sem bactéria) x 3 (níveis de irrigação: 100%, 50% e 25% de água), perfazendo um total de 6 tratamentos com 6 repetições. Ao avaliar o efeito da bactéria Serratia nematodiphila no tratamento com irrigação à 25% de água, observou-se que os valores médios  do comprimento radicular das plântulas de tomateiro foi o que mais sofreu o estímulo no crescimento radicular quando comparado aos demais níveis de irrigação. Esses resultados sugerem que em condições de maior déficit hídrico a bactéria é capaz de mitigar a seca promovendo o crescimento radicular.Research, Society and Development2020-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/869410.33448/rsd-v9i10.8694Research, Society and Development; Vol. 9 No. 10; e6109108694Research, Society and Development; Vol. 9 Núm. 10; e6109108694Research, Society and Development; v. 9 n. 10; e61091086942525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/8694/7989Copyright (c) 2020 Tiandra Silva Carvalho; Ana Carla Pinheiro Limahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCarvalho, Tiandra SilvaLima, Ana Carla Pinheiro2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/8694Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:06.822660Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
