Abstract

One source of nutrients that influences how a plant grows and produces is fertilizer. fertilization that is possible with both inorganic and organic fertilizers. The purpose of this study is to ascertain how the development of bok choy is impacted by vermicompost, NPK fertilizer, and their combination. Design using RAL two components with five fertilization levels each, repeated three times, such that the experimental unit employed up to 75 plants. The first factor is the dose of vermicompost organic fertilizer consisting of K 0 = 0  gr (control), K1  = 50 gr, K2 = 100 gr, K3 = 150 gr and K4 = 200 gr. The second factor is the dose of NPK fertilizer (16:16:16) consisting of N 0 = 0 gr (control), N 1 = 0.3 gr, N2 = 0.6 gr, N3 = 0.9 gr and N4  = 1.2 gr. The ANOVA test was used to evaluate the data. The findings revealed that the vermicompost treatment had no appreciable impact on the plant's height, number of leaves, leaf area, wet weight, or dry weight characteristics. The use of NPK fertilizer has a sizable influence on plant properties such as height, leaf count, leaf area, wet weight, and dry weight. Vermicompost and NPK fertilizer together have a considerable influence on the metrics of plant height, leaf count, wet weight, and dry weight.

Abstract

This study aims to determine the effect of vermicompost, urea fertilizer and the interaction of vermicompost and urea fertilizer treatments on corn vegetative growth. The research design used was a 2-factor design. The first factor was the application of vermicompost and the second factor was the application of urea fertilizer which was carried out with 3 replications. The doses of vermicompost were 0, 0.5, 1.0, 1.5, and 2.0 kg. The doses of urea fertilizer were 0, 0.6, 1.2, and 1.8 g. The research data were analyzed using Anova. The results of the study were: Vermicompost treatment had a significant effect on stem height, number of leaves and leaf length but had no significant effect on leaf width and corn stem diameter; application of urea fertilizer could increase all measured corn growth parameters; interaction between urea fertilizer and vermicompost treatment had no significant effect on all measured corn growth parameters.
