Efecto biofertilizante de azolla - anabaena en el cultivo de maíz (Zea mays L.)

The deterioration of natural resources in agricultural activities, has motivated the search for new alternatives to enrich thesoil with macro and micro nutrients sustainably, for the benefit of future generations, just as you think about the conser- vation and maintenance of water, avoiding eutrophication problems by the accumulation of fertilizers (nitrates andnitrites) leached and deposited in natural sources, for this purpose they have been measured several agro ecologicaloptions that provide proper nutrition and a delicate ecological balance; in this investigation at field level in maize cultivation and different states it applied dose of azolla as a natural source of nitrogen to enrich the soil in the canton Cevallos, Tungurahua province. Anabaena floors of the town, based on the state of azolla and the level established for such preparation, the states of azolla. Six mixtures were prepared substrates azolla studied were: Dry A1 and A2 in the fresh state;the doses were established in relation to the volume of azolla against soil volume used: (0.5: 1) (0.75: 1) and (1: 1). Thedata collected were plant height and percentage of nitrogen in dry matter at 15, 30, 60 and 90 days. All this in order toestablish the amount of nitrogen contributed by azolla as biofertilizer in growing corn. The best results were presented at  the A1D3 (azolla dry-Dose 1: 1) treatment given plant height 15.02 cm at 15 days, 35.88 cm 30 days, 53.22 cm 60 66.12days and 90 days; to 0.54% nitrogen percentage at 15 days, 0.90% at 30 days, 1.68% at 60 days and 2.08% after 90 days.In conclusion, the use of Azolla as a bio-fertilizer rich in nitrogen is feasible, as has been demonstrated in this researchthat the corn plant benefits from the contribution of this material, improving sustainable agricultural practices. It isrecommended to expand this research in the same crop or other commercially important crops until the end of its production cycle, to report the results of these.El deterioro de los recursos naturales en las actividades agrícolas, ha motivado la búsqueda de nuevas alternativas quepermitan enriquecer el suelo con macro y micro nutrientes de manera sostenible, para beneficio de las futuras generaciones, igualmente se piensa en la conservación y mantenimiento del agua, evitando problemas de eutrofización por laacumulación de fertilizantes (nitratos y nitritos) lixiviados y desembocados en fuentes naturales, con este propósito sehan medido varias opciones agroecológicas que brindan una nutrición adecuada y un delicado equilibrio ecológico, en lapresente investigación a nivel de campo en el cultivo de maíz se aplicó diferentes estados y dosis de azolla como fuentenatural de nitrógeno para enriquecer el suelo en el cantón Cevallos, provincia de Tungurahua. Se prepararon seis mezclasde sustratos de azolla con suelo de la localidad, basados en el estado de azolla y la dosis establecida para dicha elaboración, los estados de azolla estudiados fueron: A1 en estado seco y, A2 en estado fresco; las dosis se establecieron enrelación al volumen de Azolla frente al volumen de suelo utilizado: (0.5:1), (0.75:1) y (1:1). Los datos recopilados fueronaltura de planta y porcentaje de nitrógeno en materia seca a los 15, 30, 60 y 90 días. Todo esto con la finalidad de establecer la cantidad de nitrógeno aportado por azolla como biofertilizante en el cultivo de maíz. Los mejores resultados sepresentaron en el tratamiento A1D3 (azolla en estado seco-Dosis 1:1) teniendo en altura de planta 15.02 cm a los 15 días,35.88 cm a los 30 días, 53.22 cm a los 60 días y 66.12 a los 90 días; para porcentaje de nitrógeno 0.54 % a los 15 días,0.90 % a los 30 días, 1.68 % a los 60 días y 2.08 % a los 90 días. En conclusión, el uso de la azolla como un biofertilizante rico en nitrógeno es factible, ya que se ha podido demostrar en esta investigación que la planta de maíz se beneficiadel aporte de este material, mejorando las prácticas agrícolas sostenibles. Se recomienda ampliar esta investigación eneste mismo cultivo o en otros cultivos de importancia comercial hasta terminar su ciclo productivo, para reportar losresultados obtenidos en estos

Compatibilidad y sobrevivencia de microorganismos benéficos de uso agrícola (Beauveria bassiana, Bacillus thuringiensis y Paecilomyces lilacinus) en compost

Compatibility and survivorship of beneficial microorganism in compost were evaluated in order to provide new alternatives toclean production in agriculture. The study was conducted at the Ecological Farm belonging to the Consejo Provincial deTungurahua, Ecuador. Four treatments were considered related to dose of several beneficial microorganisms (EMs). After aninterval of 30 or 60 days after composting process, analysis of nutritional biological content showed compatibility and survivorship of the EMs, which live together and reproduce on the organic fertilizer. Concerning physic-chemical analysis higherorganic matter content, pH, electrical conductivity, nitrogen, phosphorous, potassium and calcium were evidenced in T1: 100cc Beauveria bassiana - 100 cc Bacillus thuringiensis - 100 cc Paecilomyces lilacinus. From the results obtained willoffer the possibility of using beneficial microorganisms to optimize their performance in obtaining compost of betternutritional and biological quality, so that gradually reduce the use of agrochemicals.Se evaluó la compatibilidad y sobrevivencia de microorganismos benéficos en la elaboración de compost, con el objeto degenerar nuevas alternativas de producción limpia en el campo agrícola. El estudio se llevó a cabo en la Granja Agroecológicadel Consejo Provincia de Tungurahua Ecuador. Fueron considerados cuatro tratamientos relacionados con las dosis de losmicroorganismos benéficos (EMs). El análisis del contenido nutricional biológico a los 30 y 60 días después de iniciado elproceso de compostaje demostró la compatibilidad y sobrevivencia de los EMs, los cuales convivieron y reprodujeron en elabono orgánico. Con referencia al contenido físico-químico, el mayor contenido de materia orgánica, pH, conductividadeléctrica, nitrógeno, fósforo, potasio y calcio fue registrado en el T1: 100 cc de Beauveria bassiana - 100 cc de Bacillusthuringiensis - 100 cc de Paecilomyces lilacinus. De los resultados obtenidos ofrecerá la posibilidad de utilizar microorganismos benéficos para optimizar su desempeño en la obtención de compost de mejor calidad nutricional y biológica, demanera que se disminuya progresivamente el uso de agroquímicos
