Plant density and growth regulator applications in a tomato crop for industrial processing

Growth regulators are used in agriculture to reduce vegetative growth, promote flowering and fruiting processes, and regulate production alternations. In this study, the effects of the use of paclobutrazol (PBZ) and different plant arrangements on the development and productive yield tomatoes grown...

description	Growth regulators are used in agriculture to reduce vegetative growth, promote flowering and fruiting processes, and regulate production alternations. In this study, the effects of the use of paclobutrazol (PBZ) and different plant arrangements on the development and productive yield tomatoes grown for industrial use were evaluated. This experiment was carried out in the experimental area of the Universidade Estadual de Goiás, in a randomized block design with a 2×5 factorial arrangement (presence of PBZ and absence of PBZ in seedlings × planting spacing), with four replications and ten plants per plot. The paclobutrazol (growth regulator) applications were carried out in seedlings 15 days after emergence by applying 3.5 mL of the solution per tray at a concentration of 42.5 mg L-1 using a commercial product containing 25% of the active ingredient for the solution. The spacings were 0.15, 0.20, 0.25, 0.30, and 0.35 m between plants and 1.4 m between rows, corresponding to populations of 47,619; 35,714; 28,714; 23,809 and 20,408 plants/ha, respectively. The initial growth and development of the seedlings, characteristics related to productivity, and the physical and chemical quality of fruits harvested in each experiment were evaluated. It was observed that the application of paclobutrazol influenced the phylotechnical characteristics and technological quality of tomato fruits grown for industrial processing. The planting spacings between 0.21 and 0.27 m had better crop development and productivity.

Los reguladores del crecimiento se utilizan en la agricultura para reducir el crecimiento vegetativo, promover los procesos de floración y fructificación, además de regular la alternancia de producción. En este estudio, los efectos del uso de paclobutrazol (PBZ) y diferentes arreglos de plantas en el desarrollo y el rendimiento productivo de los tomates para la industria. El experimento se realizó en el área experimental de la Universidade Estadual de Goiás, en un diseño en bloques aleatorizados, en un arreglo factorial de 2×5 (presencia de PBZ y ausencia de PBZ en plántulas × distancia de siembra), con cuatro repeticiones y diez plantas por parcela. La aplicación de paclobutrazol (regulador del crecimiento) se realizó en plántulas 15 días después de la emergencia aplicando 3,5 mL de la solución por bandeja a la concentración de 42,5 mg L-1 utilizando el producto comercial que contiene el 25% del ingrediente activo para la solución. Los espacios disponibles fueron de 0,15; 0,20; 0,25; 0,30 y 0,35 m entre plantas y 1,4 m entre hileras, correspondientes a poblaciones de 47.619, 35.714, 28.714, 23.809 y 20.408 plantas/ha en cada espacio. Se evaluó el crecimiento inicial y el desarrollo de las plántulas, las características relacionadas con la productividad y la calidad física y química de los frutos cosechados en cada experimento. Se observó que la aplicación de paclobutrazol influyó en las características filotécnicas y la calidad tecnológica de los frutos de tomate para el procesamiento industrial. En cuanto a la densidad de siembra, el espacio de siembra entre 0,21 a 0,27 m mostró un mejor desarrollo del cultivo y productividad.
