Resumo

The study was carried out in Santa Maria, RS – Brazil, with the objective of
evaluating the vermicompost effect on the production and nutritional quality of wheat
hydroponics forage, cultivated in protected environment (high tunnel). It was adopted
the experimental design in blocks at random, distributed in factorial scheme 2 x 4,
two nutritional solutions; SNS – inorganic nutritive solution according to Santos et al.
(2004)’s recommendation, SNSC – organic nutritive solution partly corrected
attending Santos et al (2004)’s recommendation, and four periods of harvest (4, 8, 12
and 16 days after sowing). It was observed significance (P<0.05) to interaction
nutritive solution x periods of harvest to variables: dry matter (DM), crude protein
(CP), soluble protein (SP) and neutral detergent fiber (NDF). The variable ones
presented square response to the period advance of harvest, being positive to DM
and negative to CP, SP, and NDF, not only to SNS but also to SNSC. The period
advance of the harvest in production of hydroponics forage determined linear
increase in acid detergent fiber (ADF) and lignin (LIG), and linear reduction of “in
vitro” dry matter digestibility (IVDMD). The forage cultivated with SNS presented
higher substance of ADF and of IVDMD in relation of SNSC. The LIG substance did
not obtain significant difference (P<0.05) among the solutions. Therefore, the organic
solution of bovine vermicompost besides offering the hydroponics forage production
of good nutritional quality of wheat, it allows the use of residue produced in property,
decreasing the production cost of nutritive solution.
