Abstract

Germination and emergence of seedlings is the starting point for the growth and development process. development of all annual crop plants, therefore, good germination and emergence of seeds to achieve high yield, among other factors. The objective was to evaluate the emergence and initial growth of seedlings in different cultivation locations. On August 19, 2023, at the UNIFEOB School Farm, experiments were carried out for the subject “Seed Production and Technology”.1 There were four experiments with planting corn seed (Zea mays), cultivar Nidera NS 90 in 18 culture cells, with three different depths (3 cm, 5 cm and 10 cm). O planting substrate was Garden Plus, composed of peat, with mineral fertilizers (N=0.01%, P2O5=0.06% and K2O=0.03%) and calcitic limestone (3.0%), plus sand. The proportion it was 3/1 (Garden Plus/sand) for the four experiments. It was conducted in three locations: 2 São João da Boa Vista/SP, 1 Mogi Guaçu/SP and 1 Muzambinho/MG.
