SLAUGHTERHOUSE WASTEWATER IMPROVE NUTRIENT LEVEL IN APIUM GLAVIOLENSHASAN BASRI JUMIN, T. ROSMAWATY, ANI PUTRI YANI AND M. NURAbstract The combination between waste-water of slaughterhouse and nitrogen fertilizer to reach the suitable dose in mean relative growth rate were found in Apium glaviolen. Growth rapidly of net assimilation rate with sigmoid pattern until 42 days and than growth horizontally. Animal slaughterhouse waste 100 mL/L combined with 0.1 g/kg nitrogen fertilizer/kg soil showed the best treatment for increasing the vegetative growth of Apium glaviolens. This is indicated by net assimilation rate and mean relative growth parameters. Growth gradually decrease after 35 days of planting and that time the plants were harvested. Between all vegetative growth parameters has only 100 mL/L slaughterhouse waste combined with applied 0.1 g/kg nitrogen fertilizer showed highest vegetative growth.
