As part of the rhizosphere microbiota, actinomycetes interact with their host by releasing metabolites that positively influence their host’ growth. The main objective of this study was to evaluate the plant growth-promoting capacity of actinomycetes isolated from the rhizosphere of potato crops collected in the city of San Jeronimo, Andahuaylas, Peru. Forty-nine actinomycetes strains were isolated and screened for their capacity to solubilize phosphates, fix atmospheric nitrogen, produce indole acetic acid (IAA) and produce siderophores. Out of the total number of isolates, 33 (63.27%) solubilized phosphates, 42 (87.72%) fixed atmospheric nitrogen, 10 (20.41%) produced IAA and 18 (24.49%) were siderophore producers; strains AND 13 and AND 16 being the top performers. AND 13 was identified by 16S RNAr gene amplification as Streptomyces sp. The results indicate that actinomycetes can be...

El propósito principal de esta investigación es determinar la relación que existe entre la psicomotricidad y el aprendizaje en el área curricular de comunicación de los niños de 3 años del aula verde del CEAUNE -2014, este estudio tiene importancia académica porque permitirá conocer los niveles de psicomotricidad, así como los niveles de aprendizaje en el área curricular de comunicación de los niños y niñas, y se demostrará la relación que existen entre estas dos variables. Se planteó como hipótesis: Existe una relación significativa entre la psicomotricidad y el aprendizaje en el área curricular de comunicación de los niños de 3 años del aula verde del CEAUNE -2014. La metodología es de tipo correlacional, con diseño no experimental transeccional correlacional. La muestra fue de 28 niños de 3 años de edad. Para la recogida de datos se aplicaron cuestionarios, ...
