초록

This experiment was conducted to investigate the effects of concentrated pig slurry using
membrane filter on growth of tomato in nutriculture. Pig slurry was filtered by ultra filtration and
concentrated by reverse osmosis process. Filtration of pig slurry was necessary to prevent the
hose clogging in nutriculture. The concentrated pig slurry (CS) and nutrient solution (NS) were
mixed by six different mixing ratios of 0 : 100, 20 : 80, 40 : 60, 60 : 40%, 80 : 20 and 100% : 0%
based on nitrogen content. The chemical nutrient solution was the solution of National Horticulture
Research Station for the growth of tomato. The concentration of nutrient solution was adjusted a
range of 1.6~2.0 mS/cm in EC.
The plant height of tomato treated with CS 20 + NS 80% was similar with NS 100% control
plot. Plant height was highest in the plot of CS 20 + NS 80%. The treatment of 100%
concentrated pig slurry was lowest in the growth characteristics of tomato. Number of cluster was
very lower in 100% concentrated pig slurry compared with plot of chemical nutrient solution.
In the beginning of growth stage, SPAD reading value was reduced in plot treated with CS 100%,
but CS 20 + NS 80% plot was higher compared to 100% concentrated pig slurry. SPAD value of
tomato leaves was decreased as the amount of CS was increased. The SPAD value also in treatment
of concentrated pig slurry was lower in the middle growth stage compared to control plot.
The dry weight of stem and leaf were 107.4, 104.2 g in plot of NS 100% and CS 20% + NS
80%, respectively. The fruit number and weight were decreased at high application plots of
concentrated pig slurry. The fruit setting of tomato showed lowest in the plot treated with 100%
concentrated pig slurry, and the growth of tomato severely decreased after application of 100% CS
treatment.
In conclusion, the growth characteristics such as plant height and fruit weight of tomato were
not significantly different between the plots treated with mixture of 20%CS + 80%NS and 100%
nutrient solution treatment. In conclusion, the mixture solution of 20% of concentrated pig slurry
and 80% of nutrient solution could be used as a nutrition solution of tomato nuticulture.
