Abstract

ABSTRACT

Field experiments on "Utilization of Compost and EM-4 in Critical Lands on Nutrient
Uptake, Growth, and Production of Shallots (Allium ascalonicum L.) in Minahasa
District", with objectives in this study were Determine the optimal compost dosage for
agricultural business; Determine the dose of EM-4 as an activator that can optimize the
use of compost; Utilizing critical land as productive land for agricultural activities;
Improving soil physical properties, soil chemistry and soil biology for critical land become
productive land . The research was conducted in a field experiment by analyzing compost
and soil before and after compost treatment. The compost dose treatment consisted of 0 ton
/ ha as a control, 15 ton / ha; 30 ton / ha; 45 tonnes / ha and 60 tonnes / ha. The EM-4
treatment consisted of 0 cc, 30cc and 60 cc / 100gr white sugar + 6 liters of water. Shallot
plants as an indicator. The incubation period for compost is 2 weeks. The research method
was a factorial experiment with a randomized block design and 3 replications. The
statistical tests used are ANOVA and LSD analysis. The results of the study showed that

compost treatment had a significant effect on growth and production of shallots, while EM-
4 had no significant effect. Compost treatment of 45 tons / ha provides maximum nutrient

uptake, growth and production of shallots.
Key words: Compost, EM-4, Shallots, Critical Lands.
