ABSTRACT - The objective of this study was to evaluate the influence of using physical protectors on the emergence and initial growth of Baru seedlings in a direct sowing system. The experiment was installed in a randomized complete block design,  testing  the  use  of  physical  protectors  (no  protection,  P0;  plastic  cup  (500  mL)  without  the  bottom,  P1; laminated wood, P2), with 12 repetitions. Weekly soil temperature monitoring was carried out in the morning and in  the  afternoon  in  the  period  between  14  and  56  days  after  sowing  (DAS).  Daily  emergence  follow-up  was  also performed, and the stem diameter, total height and number of leaves were measured at 81 DAS. The useof physical protectors  in  the  direct  seeding  of  Baru  interfered  in  the  soil  surface  temperature  on  the  sowing  point,  on  the seedling  emergence  speed  index,  seedling  survival,  stem  diameter  and  seedling  height.  Implementing  protectors slowed the  seedling emergence  speed, however it provided higher percentages of emergence, survival and greater growth in diameter and height.

RESUMO - O  objetivo  do  trabalho  foi  avaliar  a  influência  do  uso  de  protetores  físicos  sobre  a  emergência  e  o  crescimento inicial de mudas de baru em sistema de semeadura direta. O experimento foi instalado em delineamento em blocos casualizados, testando uso de protetor físico (sem protetor, P0; copo plástico (500 mL), sem o fundo, P1; laminado de  madeira,  P2),  com  12  repetições.  No  período  entre  14  e  56  dias  após  semeadura  (DAS),  foi  feito  o acompanhamento semanal da  temperatura do solo, pela  manhã e à  tarde. Foi realizado, ainda, o acompanhamento diário da emergência e, 81 DAS, foram mensurados o diâmetro do colo, a altura total e o número de folhas. O uso de  protetores  físicos  em  semeadura  direta  de  baru  interferiu  na  temperatura  superficial  do  solo  sobre  o  ponto  de semeadura,  no  índice  de  velocidade  de  emergência  das  plântulas,  na  sobrevivência  de  plântulas,  no  diâmetro  do colo e na altura das mudas. O uso de protetores tornou mais lenta a velocidade de emergência de plântulas, porém propiciou maior porcentagem de emergência, de sobrevivência e maior crescimento em diâmetro e altura.
