“…KSM can dissolve K in the soil through the mechanisms of acidolysis, chelation, exchange reactions, and complexation of the organic acids produced [14,61,62]. Likewise, the presence of PSM can make more P available for plant absorption [63]. PSM has been widely accepted as an environmentally friendly and easy-to-obtain P fertilizer for increasing soil orthophosphate concentrations and the geochemical P cycle since the early 20th century [41].…”

In an effort to mitigate the environmental impact of chemical fertilizers while promoting soil sustainability, this study investigated the potential of rhizosphere-associated microorganisms to augment nutrient uptake and growth in melon crops. Soil samples were procured from three distinct melon fields and subjected to serial dilution techniques for microbial isolation on Nutrient Agar (NA) and Potato Dextrose Agar (PDA) media. Subsequent screening identified select isolates with capabilities for nitrogen fixation, phosphorus and potassium solubilization, indole-3-acetic acid (IAA) production, and antagonism against pathogens. Two bacterial isolates, designated BS 1A and BK 1, and one fungal isolate, FW 2B, were earmarked for their plant growth-promoting microorganism (PGPM) potential. Sequence analysis revealed homology of BS 1A with Pseudochrobactrum sp., BK 1 with Bacillus cereus, and FW 2B with Trametes polyzona. A greenhouse experiment employing a completely randomized design evaluated the effects of these isolates on melon growth. Control treatments included a positive control (C+), receiving the recommended dosage of NPK fertilizer, and a negative control (C-), devoid of both NPK and microbial treatments. The application of B. cereus, Pseudochrobactrum sp., and T. polyzona was observed to significantly elevate plant biomass and nutrient acquisition, with B. cereus demonstrating the most pronounced effect, rivalling that of chemical fertilization. The results of this study highlight the potential of utilizing select soil microorganisms as biostimulants, which could play a significant role in increasing the productivity of melon crops, thereby supporting the advancement of sustainable agricultural methodologies.

“…Ello permite mejorar la nutrición vegetal debido principalmente a la solubilización de este nutriente que sintetiza el ácido indol-acético (AIA) (Chagas et al, 2016;Prasad et al, 2020), además de producir diversos metabolitos secundarios entre los que se encuentran otras hormonas de crecimiento como las giberelinas (Argumedo et al, 2009). Estos microorganismos habitan en la rizosfera de las plantas y mejoran la resiliencia de los sistemas de cultivos, ya que, además de promover el crecimiento de las plantas, incrementan su protección contra patógenos e insectos (Lanna et al, 2021).…”

El fósforo es uno de los elementos que más limitan la producción agrícola debido a su baja disponibilidad en el suelo. Los microorganismos promotores del crecimiento vegetal pueden ser utilizados como una estrategia para lograr la biodisponibilidad de este nutriente. El objetivo de esta investigación fue analizar el efecto del Trichoderma spp. asociado a la fertilización fosfatada en el cultivo de tomate. En el experimento se utilizó el diseño de bloques completos al azar con arreglo bifactorial y cuatro repeticiones. El factor A consistió en la inoculación y no inoculación de Trichoderma spp. y el factor B en cuatro dosis de fósforo: 0, 40, 80 y 120 kg ha -1 de P 2 O 5 . Las variables evaluadas fueron longitud y peso de la raíz, masa de frutos, rendimiento de frutos por planta y rentabilidad de producción. Los datos fueron sometidos al análisis de varianza y las medias comparadas por el test de Tukey al 5%. Para la longitud radical y masa de la raíz hubo interacción entre los factores, donde los mejores resultados se obtuvieron con la inoculación de Trichoderma spp. asociado a la aplicación de 120 kg de P 2 O 5 ha -1 con 0,62 m y 58 g, respectivamente. Las variables masa de frutos, rendimiento de frutos por planta y rentabilidad no presentaron interacción entre los factores. Sin embargo, se observaron de forma aislada diferencias entre las dosis de P 2 O 5, así como en la inoculación. El hongo Trichoderma spp. y la aplicación de 120 kg ha -1 de P 2 O 5 mostraron los mejores resultados en todas las variables analizadas, promoviendo el desarrollo vegetativo y la rentabilidad del cultivo de tomate.Palabras clave: Solanum lycopersicum, promotores de crecimiento, dosis de fósforo.

“…Recent studies have shown that the application of bioagents promotes a higher shoot and root biomass production of upland rice (Silva et al 2023); higher grain yield and its components in soybean (Chagas Junior et al 2022); higher leaf contents of N, Fe and Cu in oat plants (Santos et al 2021); and Ca, P, S, Zn and Cu in C. juncea, C. spectabilis and C. ochroleuca (Lanna et al 2021). Therefore, for the diversification of multifunctional microorganisms in a controlled environment, the co-inoculation of Serratia marcencens + Trichoderma koningiopsis provided significant increases in gas rates and yield of common bean (Rezende et al 2021a).…”

The search for cultivation techniques that provide productive, social and environmental benefits to the agroecosystem is of great seriousness for the sustainable intensification of agriculture. This study aimed to determine the effect of crop cover crops on the soil attributes and development of bean plants treated with the consortium of bioagents Serratia marcencens + Trichoderma koningiopsis grown in the winter. The experiments were conducted for three crop seasons, in a randomized blocks design arranged in a 2 × 8 factorial scheme, with four replications. The treatments consisted of the combination of eight cover crops with two microbial treatments. The bioagents and the mix of cover crops, especially the treatment 2 (corn) and the mixes 3 (millet, Crotalaria ochroleuca, black oat, white oat, buckwheat and coracana grass) and 5 (black oat, buckwheat, millet, Piatã grass and C. Ocholeuca), provided significant increases in the soil chemical and biological quality, with increases in the contents of Ca, Mg, K, H + Al and organic matter, as well as in the main soil pathogens that affect the bean crop, concerning fallow. In addition, there was an increase in the number of pods per plant and grains per pod. The use of these technologies provided savings, if compared to the use of chemical fertilization.
