Effect of Liquid Organic Fertilizer (Ageratum conyzoides) on Root Vegetative Growth of (Coix lacrima Jobi)

Abstract

Hanjeli is a cereal crop that has a higher protein content compared to corn and rice, so this plant has potential as an alternative food. The growth of hanjeli plants depends on the application of fertilizers and the absorption of nutrients by the roots. The root plays an important role in the absorption of nutrients, healthy roots, photosynthesis process will be optimal and get optimal growth of hanjeli plants. This study aims to determine the vegetative growth response of hanjeli plant roots using Ageratum conyzoides liquid organic fertilizer. This study used a randomized block design, namely the different doses of liquid organic fertilizer A. conyzoides. The treatments in this study were P0 (control), P1 (2.5 ml / plant), P2 (5 ml / plant), P3 (10 ml / plant), P4 (20 ml / plant), and P5 (40 ml / plant) with each treatment repeated 4 times. Observation parameters were root number, longest root length, root volume, root wet weight, dashed wet weight, root dry weight, dashed dry weight, and root drop ratio. Data will be analyzed using ANOVA if significantly different will be continued with Duncan's further test. The results of the study on the P0 treatment on the parameters of the number of roots of hanjeli plants were significantly different from other treatments. The application of A. conyzoides liquid organic fertilizer has a negative effect on the growth of hanjeli plant roots, which is to suppress root growth, but the roots of hanjeli plants can still grow at a dose of 40 ml /plant liquid organic fertilizer.
