Abstract

Objetivo Evaluar la efectividad de tres cepas de Bradyrhizobium en el desarrollo morfoagronómico de Glicine max L, cultivar Incasoy 27, en el municipio Puerto Padre. Materiales y Métodos Se desarrolló un estudio en condiciones de campo, en un suelo Fersialítico Pardo Rojizo del municipio Puerto Padre, Las Tunas, Cuba. Se aplicó un diseño de bloques al azar con cinco tratamientos (control absoluto, fertilización con NPK y las cepas de Bradyrhizobium, ICA 8001, USDA 110 y GIE 109) y cuatro réplicas. La distancia entre réplicas fue de 1 m y la semilla tenía 98 % de germinación. Durante el ciclo del cultivo, se evaluó el número de vainas por planta, el número de granos por vaina, el peso de 100 granos, el rendimiento en t ha-1 y se realizó una valoración económica. Resultados El menor número de vainas por planta se obtuvo en el control absoluto, sin diferir del tratamiento con NPK. A su vez, ambos difirieron estadísticamente (p > 0,05) de los tratamientos con Bradyrhizobium. También el número de granos por vainas fue mayor en los tratamientos inoculados, que difirieron significativamente del control. El mayor rendimiento de granos se obtuvo en las plantas inoculadas, con valores entre 1,06 y 1,23 t ha-1. Conclusiones La aplicación de cepas de Bradyrhizobium influyó positivamente en los indicadores morfoagronómicos del cultivo, lo que permite disminuir el uso de los fertilizantes minerales.

Abstract

Objective: To evaluate the agroproductive performance of three cultivars of Glycine max (L.) Merril on a loose brown soil without carbonate. Materials and Methods: The research was conducted in a farm in the Las Tunas municipality, Las Tunas province, under field conditions. A randomized block design was applied with three treatments and three replicas. Plots with an area of 11,2 m2 were used. The distance between replicas was 1 m. The seed had 98 % germination. The cultivars Incasoy-1, Incasoy-26 and Incasoy-2 were studied. During the vegetative cycle of the crop, the variables number of pods per plant, number of grains per plant, weight of 100 grains, yield in t ha-1, were evaluated. Results: The lowest number of pods per plant corresponded to cultivar Incasoy-2 and the highest one was shown by Incasoy-1, which differed statistically from Incasoy-26. The highest yield was obtained in cultivar Incasoy-1 (1,75 t ha-1), which differed from the others, and the lowest value was recorded in Incasoy-2 (0,60 t ha-1). All the cultivars reached profits in their production. The treatment that provided the highest profit was Incasoy-1, with results of 121 250.00 pesos per hectare, and cost of $0,10 per produced peso. Conclusions: The highest agricultural yield was for cultivar Incasoy-1 (over 1 t/ha) and the lowest yield for Incasoy-2. In turn, the highest net profit corresponded to Incasoy-1, as well as the lowest cost per peso. [ABSTRACT FROM AUTHOR]

Abstract

Objetivo: Evaluar la efectividad de la aplicación de tres cepas de hongos micorrízicos arbusculares en el rendimiento de Glycine max L., cultivar Incasoy 27, en un suelo fersialítico pardo rojizo, típico de la provincia Las Tunas. Materiales y Métodos: Se desarrolló la investigación en condiciones de campo, de septiembre a diciembre de 2018. Para el montaje del experimento se aplicó un diseño de bloques al azar, con cinco tratamientos y cuatro réplicas. La distancia entre réplicas fue de 1 m. La semilla utilizada provenía del INCA, con 98 % de germinación. Se establecieron cinco tratamientos: un control absoluto, fertilización con NPK e inoculación con cepas de micorrizas INCAM4, INCAM11 e INCAM2. Durante el ciclo del cultivo se evaluaron las variables número de vainas por planta, número de granos por planta, peso de 100 granos, rendimiento en t ha-1. Resultados: Se observó que el menor número de vainas por planta correspondió al tratamiento control, que difirió del resto (p < 0,05). Los mayores valores se registraron en los tratamientos inoculados, que no difirieron entre sí (51,4; 60,0 y 62,2 para INCAM 4, INCAM 11 y INCAM 2, respectivamente). En cuanto al rendimiento, los mejores resultados se obtuvieron en el tratamiento fertilizado con NPK y la inoculación con micorrizas, con valores de 2,0; 2,5; 2,7 y 2,6 para NPK, INCAM 4, INCAM 11 y INCAM 2, respectivamente. Todos los tratamientos fueron económicamente rentables. Se destacaron los inoculados. Conclusiones: La aplicación de cepas de hongos micorrizógenos arbusculares influyó positivamente en los indicadores morfoagronómicos evaluados en G. max, lo que permite disminuir el uso de los fertilizantes minerales en este cultivo.

Abstract

Objective: To evaluate the effectiveness of three Bradyrhizobium strains in the morphoagronomic development of Glicine max L, cultivar Incasoy 27, in the Puerto Padre municipality. Materials and Methods: A study was conducted under field conditions, on a reddish Brown Fersialitic Soil of the Puerto Padre municipality, Las Tunas, Cuba. A randomized block design was applied with five treatments (absolute control, fertilization with NPK and the Bradyrhizobium strains, ICA 8001, USDA 110 and GIE 109) and four replicas. The distance between replicas was 1 m and the seed had 98% germination. During the cultivation cycle, the number of pods per plant, number of grains per pod, weight of 100 grains, yield in t ha-1 were evaluated and an economic assessment was made. Results: The lowest number of pods per plant was obtained in the absolute control, without differing from the treatment with NPK. In turn, both differed statistically (p > 0,05) from the treatments with Bradyrhizobium. The number of grains per pods was also higher in the inoculated treatments, which differed significantly from the control. The highest grain yield was obtained in the inoculated plants, with values between 1,06 and 1,23 t ha-1. Conclusions: The application of Bradyrhizobium strains positively influenced the morphoagronomic indicators of the crop, which allows to decrease the use of mineral fertilizers.
