Abstract

Red chili peppers (Capsicum annuum L.) is a type of vegetable that has economic value high and contains various compounds that are useful for human health. The aim is to determine the extent of the effect of Nitrogen and phosphore on the vegetative growth of red chili plants. This study used a two- factor factorial Randomized Block Design (RAK) method. The first factor is the dose of Nitrogen Fertilizer consisting of three levels, namely N1 (5 gr/plant), N2 (10 gr/plant), and N3 (15 gr/plant), the second factor is the dose of Phosphore fertilizer with two levels, namely P1 (10 gr/plant) and P2 (15 gr/plant). Observation variables include plant height, number of leaves, and number of branches. The results showed that there was a real interaction between nitrogen and phosphore fertilizers. Nitrogen Fertilizer treatment was significantly different from plant height, number of leaves and number of branches. The best Nitrogen Fertilizer treatment was at the N3 dose level (15 gr/plant). Furthermore, in the Phosphore fertilizer treatment, the best results were obtained at the P2 level (15 gr/plant) which affected plant height, number of leaves, and number of branches.

Abstract

Garlic (Allium sativumL.) is a horticultural commodity with high economic value in Indonesia. For optimal growth and yield, garlic plants require macronutrients and micronutrients from fertilization. Micronutrients can be met, for example, by providing organic liquid fertilizer. This study aims to determine the effect of Supermes Liquid Fertilizer dosage application on garlic plant growth. The garlic varieties planted are local varieties using a 1-factor Randomized Block Design with 6 fertilizer dosage treatments: 1) 0 ml/L; 2) 1 ml/L; 3) 2 ml/L; 4) 3 ml/L; 5) 4 ml/L and 6) 5 ml/L. Supermes liquid organic fertilizer. Each treatment was repeated three times: Garlic Response to Supermes Liquid Fertilizer, therefore, there were 18 treatment trials. The results of the Supermes POC fertilizer dosage application did not show significant differences in plant height and number of leaves. However, there was a significant increase in the number of leaves and plant height at each increase in fertilizer dosage. Further research on the application of Supermes POC dosage with various higher concentrations is needed to obtain superior results.
