“…The bioinoculated treatment (C.Br+Ba) with a value of 4.43 significantly surpass both treatment Chem.trt and Control, with values 4.15 and 3.94 respectively. There are few publications on the effect of symbiotic bacteria such as Bradyrhizobium, which actively participates in biological nitrogen fixation (BNF) in legumes (Taco-Taype & Zúñiga-Dávila, 2020). In this context, in a recent study conducted by Monroy-Guerrero et al (2022), pointed out that the inoculated plants showed the best quantitative characteristics in the lateral inflorescence, as well as for the number of pods, weight of the pods and the number of locules increase to 165.1 %, 116.9 % and 14 % in comparison with the control treatment.…”

Los rendimientos de los cultivos son importantes para la seguridad alimentaria y el nivel de vida de las personas, por lo que es muy importante conocer adecuadamente sobre la asociación de microorganismos con los cultivos, para conocer sus efectos biofertilizantes y biocontroladores, que permitirán el desarrollo de bacterias del suelo, colonizadoras de raíces. de las plantas después de la inoculación en las semillas y mejorar el crecimiento de las plantas. La evaluación de la co-inoculación de bacterias que promueven el crecimiento vegetal por diferentes mecanismos, en plantas afectadas por patógenos, contribuiría a aumentar el conocimiento las interacciones de las plantas con diferentes microorganismos. El objetivo de esta investigación fue evaluar los efectos biofertilizante y biocontrolador a través de las bioinoculaciones de Bradyrhizobium y Bacillus spp. asociación de cepas. Ambos efectos se midieron durante el crecimiento de la planta a través de la variable respuesta frente a la Antracnosis sobre el rendimiento y el contenido de nutrientes de la semilla, utilizando la variedad Altagracia. El experimento se llevó a cabo en la localidad de Paltash a 3100 m s.n.m. en el Distrito de Marcará, Carhuaz, Ancash, en el campo del pequeño agricultor. Se ensayaron tres tratamientos: i) bioinoculantes Bradyrhizobium + Bacillus, ii) un tratamiento químico, y iii) un testigo (sin bioinoculantes ni químicos). El experimento de campo se llevó a cabo bajo un diseño de bloques completos al azar (RCBD) con cuatro bloques. Se evaluaron los siguientes parámetros: 1) El peso fresco y seco de la parte aérea, raíz y nódulos a los 60 días; 2) severidad de la antracnosis durante la floración, llenado de vainas y cosecha; y 3) Contenido de nutrientes de la semilla. El análisis estadístico se realizó utilizando la prueba de Duncan (IC del 95 %). Los resultados obtenidos indican que las plantas bioinoculadas presentaron las mejores características de nódulos; asimismo, la bioinoculación redujo el grado de severidad de la Antracnosis en los diferentes estados fenológicos y provocó los valores más altos en contenido de nutrientes. Se concluye que las bioinoculaciones mejoran el crecimiento del tarwi y el control de la antracnosis.

“…For this, it is important the use of an infective (capacity to nodulate) and effective (efficient for N2 fixation) Rhizobium in the legume, which implies the need to identify and inoculate strains of different origin (Fernández-Pascual et al, 2007). The inoculation of lupine roots with different strains of Rhizobium improves the levels and availability of nitrogen and carbon in the soils and therefore the vegetative development of the plant (Taco & Zuñiga, 2017). The objective of this research was to evaluate the effect of the inoculation of two Rhizobium spp.…”

Two Rhizobium strains collected from chocho (Lupinus mutabilis, Sweet) plantations in the provinces of Tungurahua and Cotopaxi, Ecuador, were isolated and characterized in order to determine the effect of their inoculation on the vegetative development of Andean chocho, under semicontrolled conditions, under agricultural plastic cover. Molecular identification was performed by partial sequencing of the 16S rRNA gene, and the contrast with the GenBank database for Rhizobium was positive (99.7% certainty). The strains obtained were suspended in a sodium alginate matrix, both polymerized in alginate beads in a 0.1 M CaCl2 solution and in suspension, to be inoculated on selected chochocho seeds. The effect of strain origin, inoculation method and substrates on plant vegetative development was evaluated. Vegetative development was influenced by the substrate used for germination. The black Andean soil allowed the migration of the bacteroids towards the roots, taking advantage of the retained capillary water. The clay loam soil determined the lower vegetative development of the plant, as it was more susceptible to dehydration under canopy conditions. Strain origin also influenced vegetative development, although it was not evident in nodulation. The strain originating in Tungurahua produced more vigorous plants, especially in interaction with the Andean black soil substrate. Nodulation was significantly influenced by the substrates sand and Andean black soil, resulting in a higher number of nodules.

Adequate intake of micronutrients is necessary to reduce widespread health issues linked to low intake of iron (Fe), zinc (Zn), boron (B), copper (Cu), and manganese (Mn). Because more than two billion people suffer from micronutrient deficiency globally, to address this problem, highly-nutritious ancestral Peruvian crops like tarwi can be an important component of food security. Thus, our work explores the tarwi micronutrient variability to select biofortified genotypes without affecting seed size and weight. Tarwi is a biofortified food because of its seeds' Fe, Zn, and B content. Furthermore, Boron showed a positive correlation between seed size and weight. At the same time, copper showed a negative correlation. Finally, six accessions (P14, P16, P21, T05, T08, and T25) that are biofortified for Fe, Zn, and B with excellent seed size and weight and with adequate levels of Cu and Mn; adding value to Peruvian biodiversity at a low cost is a starting point for a breeding program to prevent micronutrient disorders.
