The Effect of Applying Biochike+ Fertilizer to Big Chili (Capsicum annum L.) Production in Alluvial Soil and Financial Analysis

Background: Alluvial soil has poor chemical properties for the growth of large chili plants, due to high soil acidity, low organic matter and nutrient content and poor soil structure, which will directly cause the growth and production of large chilies to be suboptimal. Efforts that can be made to increase plant growth are by using a combination of biochar tankos and chicken manure biochar (Biochike+). This study aims to determine the effect of Biochike+ fertilizer on the absorption of N, P, K nutrients, growth and yield of large chili plants in alluvial soil and to determine the financial aspects of Biochike+ fertilizer production. Methods: Cultivation using polybags. The research design used a completely randomized design (CRD) consisting of a combination of biochar doses B0= Control, B1= 10 t.ha-1, B2= 20 t.ha-1, B3= 30 t.ha-1 and B4= 40 t.ha-1 and analysis of the costs and benefits of Biochike+fertilizer. The treatment was repeated 5 times so that there were 25 polybags. Result: The administration of Biochike+had a significant effect on all parameters. In the B4 treatment, the production of large chilies reached 300%, N uptake was 352%, P uptake was 200% and K uptake was 120% compared to the control. Financial analysis shows that large chili production using Biochike+ fertilizer is profitable, which is IDR 62,649,420.3 per harvest.
