In recent years, studies have aimed to identify potential additional descriptors for soybean crops. So, the present study evaluates the viability of reducing the number of seeds used in experiments by analyzing the effect of transplanting soybean seedlings on vegetative traits. The experiment was conducted in a greenhouse using seeds from the cultivars BRSGO 7560, BRSMG 752 S, CD 202, BRSGO 8360, BRS 546, and FT-Cristalina. The study followed a 6×4 factorial design in a randomized block arrangement with four replicates. Factor A consisted of six levels (cultivars), and Factor B included four transplanting periods (direct planting in the soil, transplanting at the VE, VC, and V1 stages). To produce seedlings, seeds were sown in a substrate placed in polystyrene trays. Assessments of epicotyl length, internode length on the main stem between the unifoliolate and the 1^st trifoliate leaf nodes, petiole length of the 1^st trifoliate leaf, rachis length of the 1^st trifoliate leaf, and plant height were conducted at V2, V3, and V4 growth stages. For evaluating epicotyl length at V2, V3, and V4 stages and plant height at the V2 stage, it is recommended to transplant seedlings at most at the VC stage. Significant differences were observed among cultivars for all traits evaluated.
