PROFUNDIDADES E POSIÇÕES DE SEMEADURA NA EMERGÊNCIA E NO DESENVOLVIMENTO DE PLÂNTULAS DE MORINGA

Abstract

The influence of seed position and sowing depth on seedling emergence and growth in Moringa oleifera Lam. in two laboratory experiments at Universidade Federal Rural do Semi-Árido, UFERSA, RN, Brasil. In one experiment, the influence of three sowing depths (2.0, 3.0 and 4.0 cm) were evaluated through percent of emergence, emergence velocity index (EVI), seedling height, and whole seedling dry matter. In the second, it was studied the influence of seed position (apex upward, lateral and apex down) on percent of emergence, EVI, seedling height, root length, and whole seedling fresh and dry matters. Both experiments were completely randomized with four replications of 50 seeds. Sowing at 2.0 cm deep provided higher percent of emergence, IVE and seedling height. Seed position did not affect percent of emergence and seedling dry matter, height and root length, however, when the seeds were sown with the apex upward or lying, seedlings had greater fresh matter and higher EVI.
