Abstract: The aim of this work was to verify the influence of hydrogel application during plant development on the biochemical composition of soybean grains. The experiment was carried out in a randomized complete block design with four replicates, in a 5×2 factorial scheme, with five concentrations (0, 5, 10, 15 and 20 kg ha-1) and two hydrogels sources (Hydroplan and Polim-Agri). The soybean cultivar used was MonSoy 8644.The biochemical contents evaluated were: oil, soluble carbohydrates, amino acids, starch, and proteins. The use of hydrogel was an alternative for grain production, since there no major changes in the contents of the biochemical compounds analyzed here.
1) The use of hydrogel for the maintenance of soybean yield when cultivated in water deficit do not impaired the grain biochemical quality.
2) There is an interaction between carbohydrates and proteins levels, but not between oil and proteins in the treatment with hydrogel’s doses.
