Efficient Microorganisms Applied to the Soil and in Cover on the Quinoa Crop

Abstract

The present study had as objective to know the effects of the natural fertilizer, from a biological compound of Efficient Microorganisms (EM-4), applied to the soil and in cover of quinoa, over its phytotechnics properties and its production. The experiment was conducted in a greenhouse, in a totally randomized block design, in a factorial scheme 4x2+1 with three replicates. The first factor constituted of four doses of EM (3, 6, 9 and 12%) applied to the soil before sowing, the second factor was the application or not of the compound via foliar. The additional treatment was considered a control treatment without any application of EM. It was evaluated plant height, inflorescence height, stem diameter, inflorescence diameter, root length, root volume, root dry mass and production. The results indicate that the use of Efficient Microorganisms (EMs) increases the production in 40% independent of the dose applied, when compared to the control. The foliar or soil application of EM-4 did not influence in the production components and in the production of quinoa.
