Enhancement growth of plantlet Gracilaria sp. with additional fermented fertilizer

Abstract

The purpose of this research is to know the influence of additional fermented fertilizer to the growth of plantlet Gracilaria sp. during acclimatization stage. The comparison of composition fermented fertilizer from Leucaena leucocephala leaves : Moringa oleifera leaves which used were 75%:25%, 50%:50%, 25%:75% and control without additional fermented fertilizer. The best plantlet growth after seven weeks testing, found in comparison 25%:75% with enhancement plantlet growth up till 32,4%, followed with comparison 50%:50% with enhancement plantlet growth up till 27,1%, the last with comparison 75%:25% and control which both show enhancement plantlet growth up till 13,5%. Based on this result, we carried out further testing with comparison 20%:80%, 15%:85%, 10%:90% and 5%:95% but the plantlet growth result only as much 12,67%; 26,67%; 24,67% and -0,09% so we recommend to use combination fermented fertilizer from Leucaena leucocephala leaves : Moringa oleifera leaves with comparison 25%:75% in acclimatization step since it’s not only increase the weight but also the length and number of shoots. However, it’s necessary to do further testing using other fertilizer raws to get better plantlet growth result.
