EVALUATION OF THE GROWTH AND INITIAL DEVELOPMENT OF THE CASSAVA CULTURE WITH APPLICATION OF BIOLOGICAL INOCULANT

Abstract

This article sought to observe the interaction of cassava plants with the application of biological inoculant. Despite being a resistant plant, it requires fertilizers to be used when planting to obtain high productivity. Therefore, the use of biological inoculants can be an alternative for producers, especially due to their low cost. The purpose of the research was to carry out a study with the objective of understanding the action of the biological inoculant on the cassava crop in its initial development, in different doses and application methods. The experiment was conducted in pots, with a 2 x 3 factorial scheme (application methods x doses of biological inoculant) and the control, with 4 replications of each treatment. Two application methods were used: 1) Immersion; 2) Spraying, with doses of 15, 20 and 25 ml diluted in 1000 ml of water. After 40 days, the height of the aerial part, depth of the roots, number of leaves, weight of the aerial part and roots and dry matter content were evaluated. The treatments responded differently to the variables analyzed. Above all, a greater number of leaves per plant, shoots, root weight and influence on dry matter were observed in some doses of the inoculant.
