Landrace maize variety in the production of hydroponic forage with the use of biofertilizer

Abstract

Hydroponic fodder production (FH) represents a sustainable and economical alternative for
food supplementation and can be produced at any time of the year. The objective of this work
was to evaluate biofertilizer doses in the production and quality of FH of Landrace maize.
The experiment was carried out in a greenhouse at the Phytotechnology Laboratory at UENF,
Campos dos Goytacazes, RJ. The work contained six treatments corresponding to the five
volumes of biofertilizer and one treatment with nutrient solution (SN). The experimental design
was a randomized block design with four replications. The height, dry matter, crude protein, fat,
ash, N, P and K content in the total forage and shoot were analyzed. On average, K content
in shoot, total fodder and dry matter content were higher in biofertilizer treatments compared
to SN treatment. Thus, it is recommended the substitution of SN for the biofertilizer in the production
of corn FH.
