Show other versions (1)

As an alternative to the excessive use of synthetic fertilizers, farmers use microorganisms that promote growth in plants, to increase roots growth, strengthen natural mechanisms that react to diseases and insects and increase production. The objective of this study was to evaluate the potential of agricultural plaster combined with Bacillus cereus, B. subtilis, Pseudomonas fluorescens and Trichoderma harzianum as plant growth promoter. Its soil application will allow selecting the most productive combination, with higher quality and crop yield. The design was completely random, with three treatments applied to potatoes cultivation (Solanum tuberosum L.) in shaded house conditions and drip irrigation. The treatments were: control (T1), T. harzianum combined with 40 kg ha?1 calcium (T2), B. cereus, B. subtilis, P. fluorescens and T. harzianum combined with 40 kg ha?1 calcium (T3); the source of calcium in T2 and T3 was agricultural gypsum. The evaluated variables were plant height, chlorophyll content, numbers and nutritional composition of leaves, weight and volumetric weight of the tuber. The viability of the microorganisms in the rhizosphere was determined with selective agars for each type of microorganism. There were no statistical differences regard on chlorophyll between treatments; the control significantly exceeded in height compared to the plants from T2 to T4; the number of tubers (51.5 %) and yield (49.4 %) from T3 was significantly higher than T1. At the biocontrol in the tuber for Streptomyces T3 was better (9 %) than T1 (32.14 %). T3 had a higher yield and better standard quality.

Como alternativa al uso excesivo de fertilizantes sintéticos, los agricultores adoptan el uso de microorganismos promotores de crecimiento en plantas, para potenciar el crecimiento de raíces, fortalecer mecanismos naturales de reacción a enfermedades e insectos y aumentar la producción. El objetivo de este estudio fue evaluar el potencial del yeso agrícola en combinación con Bacillus cereus, B. subtilis, Pseudomonas fluorescens y Trichoderma harzianum como promotor de crecimiento vegetal. Su aplicación al suelo permitirá seleccionar la combinación más productiva, con calidad y rendimiento mayores del cultivo. El diseño fue totalmente al azar, con tres tratamientos aplicados al cultivo de papa (Solanum tuberosum L.) en condiciones de casa sombra y riego por goteo. Los tratamientos fueron: testigo (T1), Trichoderma harzianum combinado con 40 kg ha?1 calcio (T2), B. cereus, B. subtilis, Pseudomonas fluorescens y Trichoderma harzianum combinados con 40 kg ha?1 calcio (T3); la fuente de calcio en T2 y T3 fue yeso agrícola. Las variables evaluadas fueron altura de planta, contenido de clorofila, composición nutrimental de hoja y número, peso y peso volumétrico del tubérculo. La viabilidad de los microorganismos en la rizósfera se determinó con agar selectivo para cada tipo de microorganismo. En el clorofila no hubo diferencias estadísticas entre los tratamientos; el testigo superó significativamente en altura a las plantas de T2 a T4; el número de tubérculos (51.5 %) y rendimiento (49.4 %) de T3 fue significativamente mayor que T1. En el biocontrol en tubérculo contra Streptomyces T3 fue mejor (9%) que T1 (32.14 %). T3 tuvo rendimiento mayor y calidad estándar mejor.
