The objective of this research was characterize and determine the effect of native strains of Azotobacter spp. on the vegetative growth of Lycopersicon esculentum Mill. "Tomato" as an alternative to the indiscriminate use of chemical fertilizers. Samples were taken from roots and rhizosphere soil of vegetables from which dilutions (10-4) in Ashby-sucrose broth and incubated at 30 °C to observe a yellow color, turbidity and surface film. The genus Azotobacter was identified in mineral agar without nitrogen and Ashby-benzoate, obtaining 96 strains with a yield of 7.10 to 57.99 mgL-1 indoleacetic acid, 0.13 to 1.64 mgL-1 of fixed nitrogen as ammonium and up to 1.61% efficiency in the solubilization of phosphate Bayovar rock. It obtained a cell suspension (108) of each of the four strains with the highest values and inoculated independently and in consortium, as well as a combination with 5...

La presente tesis titulada “Control Interno Gubernamental en la Gestión de Recursos Humanos en la Municipalidad Distrital de Yauyos de la Provincia de Jauja”, se inició con la identificación de una serie de debilidades en la gestión de recursos humanos, como la carencia de directivas internas que regulen los subprocesos de reclutamiento, selección y contratación de personal; asimismo, la Municipalidad no realiza evaluaciones del desempeño laboral, por ende, no identifica las áreas críticas donde el personal necesita capacitación ni elabora un Plan Anual de Capacitación; esta situación es consecuencia de la inexistencia de un control interno gubernamental formal, conllevando por esta razón a formular la siguiente interrogante: ¿Cuál es el modelo de control interno gubernamental que permite una adecuada gestión de recursos humanos en la Municipalidad Distrital de Yauyos...
