Application of Trichoderma atroviride isolates in three soybean varieties in the southern Amazon
Microorganisms ,Agriculture, Nutrient Absorption
Soybean is one of the most important legumes in agriculture, because it has high nutritional value and wide range of uses, from human and animal feeding. However, for better crop development and, in order to meet the demand for food, new management techniques that are to increase crop productivity need to be integrated into the productive sector. Thus, seeking economic alternatives, easy to apply and efficient in agriculture, the study aimed to analyze the effect of the application of Trichoderma atroviride isolates in three soybean cultivars, in order to prove their action as a growth promoter and on the protection of soybean plants. The experiment was carried out in a randomized block design, in the factorial scheme 8 x 3, and the applications of Trichoderma atroviride isolates were in three soybean cultivars ( Olimpio, Mamoré, Extrema), consisting of treatments Trichoderma-couve (TC), Trichoderma- soja (TS), Trichoderma-empresa (TM), Trichoderma- cold chamber (TL), Trichoderma- okra (TQ), Trichoderma- Pleurotus (TF), Trichoderma-comercial (TT), and the control , applications are carried out via foliar. The research was conducted in an experimental area in the municipality of Alta Floresta-MT, located in the Southern Brazilian Amazon. In the first chapter, the effect of treatments on morphological and productive characteristics of soybean crop was discussed. It was possible to observe that the use of Trichoderma atroveride isolates provided significant effects on soybean, both morphological and productive factors
