Effectiveness Of Applying Organic And Inorganic Fertilizers On The Growth And Yield Of Shallots (Allium ascalonicum L.) In Acid Soil Conditions

Abstract

Shallots (Allium ascalonicum L.) are the main vegetable commodity in Indonesia. The demand for shallots continues to increase every year, both for national needs and for export. To meet these needs, the sustainability of domestic shallot production must be increased and sustainable. The problem that occurs in the cultivation of shallots is the excessive use of inorganic fertilizer which can have a negative impact on the land. The negative impact is in the form of decreasing soil acidity levels. The aim of this research is to determine the effectiveness of applying organic and inorganic fertilizers to the cultivation of shallot plants on acidic land. The research uses experimental methods in the field using polybags. The environmental design uses a Randomized Block Design (RBD). The treatments tested in this experiment were A = 100% dose of goat manure organic fertilizer, B = 100% NPK Mutiara inorganic fertilizer, C = 50% organic fertilizer + 50% inorganic fertilizer, D = 50% organic fertilizer + 25% inorganic fertilizer. To see the differences between treatments, the Least Significant Difference (LSD) test was tested at the 95% level. The research results showed that giving organic fertilizer + inorganic fertilizer showed significant results compared to giving 100% inorganic fertilizer. Providing 50% organic fertilizer + 50% inorganic fertilizer showed the best tuber dry weight results, while 50% organic fertilizer + 25% inorganic fertilizer had the best effect on tuber wet weight. The results of this research provide information to farmers in implementing sustainable agriculture in shallot farming.
