INCREASED YIELD OF COMMON BEAN DURING INTERACTION BETWEEN ORGANIC SELENIUM AND TRICHODERMA SPP

Abstract

Common beans are an essential food in the diet of most Brazilians, highlighting the need to develop more sustainable methods that promote the increase of their productivity. In this context, understanding the effects of the use of organic selenium and associated with Trichoderma spp. on the performance of this crop becomes essential to achieve these goals. In this sense, the present study aimed to evaluate the interaction between Trichoderma spp. and organic selenium in the increase of common bean yield in Imperatriz, MA. The experiment was carried out in a field environment, at the Center for Technological Diffusion, located in Imperatriz, Maranhão, Brazil, in a randomized block design, with 4 treatments in 4 replications. The treatments consisted of foliar and soil application of organic selenium and Trichoderma spp. The results show that the use of Selenium + Trichoderma spp. had a significant impact on the production of dry matter, fresh matter, number of pods, number of grains per pod, and weight of 100 grains. The increase in these variables ended up corroborating the increase in productivity.  Therefore, the combined use of Selenium + Trichoderma spp. Becomes possible and enhances the performance of the common bean crop. Thus contributing to the increase in the productivity of common beans, as well as to the promotion of sustainability and the increase in the income of local producers.
