University of the Altiplano, located in the district of Paucarcolla province and Region Puno, located at 3850 m.a.s.l. The aim of this research was to evaluate the agroecological production of quinoa ecotypes of colors (Chenopodium quinoa Willd.) by the use of Effective Microorganisms (EM); to evaluate the physical and chemical characteristics of the soil at the beginning and end of the experiment; to characterize the pigments of the quinoa ecotypes and compare production costs. The experiment was conducted under a randomized complete block design with a factorial arrangement of 9 x 3 x 2, of nine quinoa ecotypes, three doses of EM and two agroecological practices (organic matter and ornithological control) with 54 treatments in 3 blocks and a total of 162 experimental units. The soil analyzes were performed by routine procedures, the microbiological analysis was carried out by coun...

Con el fin de evaluar la producción ecológica de nueve ecotipos nativos de quinua de colores (Chenopodium quinoa Willd.) utilizando dos dosis de microorganismos eficaces (EM) y prácticas agroecológicas (control de aves y uso de compost), así como evaluar su efecto en las características físicas-químicas y biológicas de los suelos, determinar los costos de producción e identificar los pigmentos de estos ecotipos, un módulo experimental se ha establecido en Illpa, ubicada en Paucarcolla, Puno, Perú, a una altitud de 3.850 metros. Los ecotipos de quinua con prácticas agroecológicas mostraron un rendimiento promedio de 1318,65 kg/ha en comparación con 857,63 kg/ha mostrados por ecotipos sin prácticas agroecológicas. La triple interacción (Ecotipos de quinua x Dosis de EM x Aplicaciones agroecológicas) ha tenido un efecto sinérgico expresado en 3 072 kg/ha de rendimiento e...

The use of endophytic fungi is an effective alternative to control pathogens, improve plant metabolism and yield in crops. The objective of this study was to assess the effect of five different strains of Trichoderma sp. on the growth and yield of quinoa plants (Chenopodium quinoa Willd) by using two methods of inoculation: a) pelleted seed, and b) drenching with the endophytic fungi. A completely randomized design with a 2 x 5 factorial arrangement, plus a control with five repetitions was used. The 11 treatments were evaluated with five repetitions. Yield, and aerial and root growth variables were determined. There were no interactions between strains and inoculation methods for aerial plant growth, but there were for root growth and yield. The seed pelleting method produced a higher aerial growth compared to the drench method. In root length, the greatest values were found with the TE...
