Resumen

La producción de algodón en Brasil enfrenta desafíos significativos debido al déficit hídrico, especialmente en los cultivos de segunda cosecha. Este estudio tuvo como objetivo evaluar el efecto del bioinsumo Bacillus aryabhattai (Auras®) en la germinación, el desarrollo inicial y la tolerancia al estrés hídrico del algodón. La investigación se realizó en dos fases: la primera evaluó la calidad fisiológica de cinco cultivares (BRS 286, BRS 433 FL B2RF, BRS Rubi, BRS Jade y BRS Verde) tratados con cinco dosis del bioinsumo (0, 2, 4, 6 y 8 mL kg⁻¹). En la segunda fase, el cultivar BRS Jade, que mostró el mejor desempeño inicial, fue sometido a regímenes de riego pleno y déficit hídrico durante siete días. Los resultados mostraron que la dosis de 2 mL kg⁻¹ fue la más eficaz para el desarrollo radicular. Bajo estrés hídrico, las plantas tratadas con el bioinsumo, independientemente de la dosis, mantuvieron un crecimiento en altura y acumulación de biomasa equivalentes a las plantas bajo riego pleno, diferenciándose positivamente del control sin tratamiento. Se concluye que el B. aryabhattai actúa como un eficiente bioestimulante y mitigador del déficit hídrico, promoviendo una mayor resiliencia fisiológica y morfológica en las fases iniciales del cultivo de algodón.
