“…In this aspect, plants such as peanuts, soybeans, sesame, etc., have the potential to supply nutrients to animals, not only grains and seeds, but also plant biomass, as they are rich in nutrients and thus the use of biomass in animal feed would be relevant due to to the signi cant nutritional value ( Melo et al, 2018, Berto et al, 2021, stimulating the production of these crops associated with the use of technologies that allow maximum exploitation without the need to open new areas. Thus, in order to highlight the potential of soybean in the Agreste Meridional region of Pernambuco, the objective is to evaluate the production of soybean plants and regrowth.…”

The use of techniques and products that maximize the production of a crop is fundamental when considering the scarcity of areas in regions that have adequate edaphoclimatic conditions for production or climatic inconsistency in other regions. Thus, the growth of national soybean production is due to research related to the theme; however, more studies can contribute to a greater productive advance in this segment. With this, the objective was to observe the influence of cutting times and the phytostimulant on the productivity of the soybean crop. Studies developed were in two agricultural years 2014/15 and 2015/16. The plot design was used, where the plots were formed by the cutting periods (40, 50, 60, 70 and 90 days after emergence (DAE) [1]and the subplots by the application of the phytostimulant (auxin, cytokinin and gibberellin), plus the witness without cutting. The Stimulate® positively (statistically higher) influenced analyzed variables; number of total pods (NVT), number of full pods (NVC), straw yield (RP), crop growth rate (TCC), harvest index (CI) and yield (GY). Cutting the aerial part of soybean plants at 40 DAE does not reduce grain production. Treatment of soybean seed with Stimulate® increases productivity at 15% and up to 60 DAE significantly stimulates soybean growth and regrowth.
