Doses de composto orgânico comercial misturado ao solo foram utilizadas como
substrato na produção de mudas de maracujazeiro amarelo. O experimento foi conduzido no
Campus de Aquidauana, da Universidade Estadual de Mato Grosso do Sul, de setembro a dezembro
de 2007. Utilizaram-se seis ambientes protegidos: estufa plástica com pé-direito de 2,5m; viveiro
telado com Sombrite® 50%, com pé-direito de 2,5m; viveiro telado de tela termo-refletora
Aluminet® 50%, com pé-direito de 2,5m; viveiro coberto com palha de coqueiro, com pé-direito de
1,8m; estufa plástica com pé-direito de 4,0m, possuindo abertura zenital e tela termo-refletora 50%
sob o plástico e, viveiro telado de tela de sombreamento 50%, com pé-direito de 3,5m. Foram
utilizados cinco substratos com doses de 0, 7, 14, 21 e 28% de composto orgânico misturado ao
solo. Utilizou-se o delineamento em parcelas subdivididas, com dez repetições. As parcelas
principais foram os ambientes de cultivo e as subparcelas foram os substratos. Conclui-se que a
estufa agrÃcola com altura de 4,0m, o viveiro agrÃcola com altura de 3,5m e o viveiro coberto com
palha de coqueiro nativo propiciaram melhor desenvolvimento das mudas. As doses de 7%, 14% e
21% de composto orgânico se mostraram viáveis para composição de substratos com solo da região.
Contents of commercial organic compound mixed with soil were used as substrate in
the production of Passiflora edulis Sims f. flavicarpa Deg. seedlings. The experiment was carried
out in the Aquidauana Campus at the State University of Mato Grosso do Sul, from September to
December of 2007. Six environments were used: plastic greenhouse with height of 2.5m; nursery
with height of 2.5m covered by shade net with black monofilament of 50% shading rate; nursery
with height of 2.5m covered by Aluminum shading screen with shading rate of 50%; nursery with
height of 1.8m covered by straw of native coconut; plastic greenhouse with height of 4.0m, zenith
opened and thermal shade netting from Aluminet® under the roof and nursery with height of 3.5m
covered by shade net with black monofilament of 50% shading rate. Five commercial organic
compound contents of 0, 7, 14, 21 and 28%, mixed with soil were used. The experiment was carried
out in a completely randomized split-plot scheme where the environments were principal plot and
substrates were subplots. The greenhouse with height of 4.0 m, the nursery with height of 3.5 m and
the nursery covered with coconut fibers showed the best seedlings. The contents of 7%, 14% and
21% of commercial organic compounds were viable for composition of the substrates with local
soil.
