El osmoacondicionamiento de semillas es una técnica previa a la siembra que implica remojar las semillas en agua u otras soluciones para iniciar la germinación y el crecimiento temprano. En este experimento, se investigaron los efectos de diversas soluciones de primado de semillas en la tasa de germinación y el rendimiento general de las variedades de trigo Banganga y Bijaya. Las semillas fueron sometidas a diferentes tratamientos, incluyendo glicol de polietileno (PEG) (10 %), ácido bórico (0.1 %), urea (2 %), glicol de polietileno (PEG) (5 %), ZnSO4 (2 %), MoP (2 %), DAP (2 %), CaCO3 (2 %), y se utilizaron semillas no tratadas como control. Hubo una variación significativa entre los agentes de osmoacondicionamiento de semillas y también tuvieron un efecto significativo en el porcentaje de germinación, velocidad de germinación y crecimiento de plántulas de trigo. Las soluciones de CaCO3 (2 %), DAP (2 %) y las semillas no tratadas resultaron ser más efectivas, mostrando superioridad en todos los parámetros evaluados, incluyendo longitud del brote, longitud de la raíz y peso fresco. Además, Bijaya mostró parámetros de germinación más altos, mientras que Banganga presentó mejores parámetros de crecimiento. En conclusión, los hallazgos sugieren que el uso de Bijaya con DAP (2 %) o CaCO3 (2 %) como agentes de priming de semillas favorece la germinación y crecimiento de las plántulas de trigo. Esta investigación arroja luz sobre el potencial de varios agentes químicos aplicados durante la osmoacondicionamiento de semillas para mejorar la germinación y el crecimiento de dos variedades diferentes de trigo.
