Adubação fosfatada e aplicação de bioestimulante na cultura do feijão comum (Phaseolus vulgaris L.)

To increase common bean productivity, it is necessary to implement techniques and procedures that analyze the advantages related to plant resistance to environmental stresses, as well as greater efficiency in the use of mineral elements in the soil, resulting in possible increases in crop yield. Given the above, the objective of this study was to study the effect of applying the plant biostimulant Stimulate® in association with different doses of phosphorus in common bean (Phaseolus vulgaris L.) crops. The experiment was conducted in a greenhouse located in the horticulture sector of IFMG-SJE in a 5x2 factorial scheme, in a randomized block design (RBD), with four replications. The first factor consisted of five doses of P (0, 60, 120, 180 and 240 mg/dm³) and the second factor consisted of the application of the biostimulant Stimulate® (without application and with foliar application). The analyses were performed at three different phenological stages of the crop; At 40 days after planting (DAP), the parameters analyzed were: stem diameter, relative chlorophyll content; at 52 DAP, the following variables were evaluated: stem diameter, relative chlorophyll content; at the end of the experiment 72 DAP, the plants were collected and the dry matter mass of leaves, stem, pods and roots was measured. The data were obtained and subjected to analysis of variance (ANOVA) and compared by Tukey's test at 5% probability in the Sisvar statistical program.
