摘要

Seed size and sowing depth are important factors for an adequate plant stand in soybean crops. This study aimed at assessing the emergence and morphological development of soybean plants, affected by seed size and sowing depth in sandy texture soil. The trial was carried out in a greenhouse with an experimental design of randomized blocks, organized in the factorial scheme 3 x 3. The factors were seed size (sieves 6.0, 6.5, and 7.0 mm) and sowing depth (2.0, 4.0, and 6.0 cm) with four replications. We assessed the emergence, emergence speed index, mean time of emergence, number of leaves per plant, stem diameter, plant height, dry mass of leaves, dry mass of stem, dry mass of root system, dry mass of shoot, total dry mass of plant, leaf area, root system volume, root system density, shoot/root ratio, ratio of leaf area, and ratio of leaf dry mass. The seed size does not influence the emergence of soybean seedlings; however, the seeds of sieve 7.0 mm produce plants with a higher dry mass of stem, dry mass of shoot, and root system volume. The soybean sowing at 4.0 cm depth resulted in the highest morphological development.
