“…Chemical fertilizers are relatively inexpensive, and are rapidly taken up by plants Chen (2006). izers resulted in surface and ground water pollution, killing of useful microbes, acidification of the soil (Zainal et al, 2021). In contrast, organic manure significantly increased the soil characters such as pH, nitrogen, available phosphorus, exchangeable potassium, calcium, and magnesium (Anggita et al, 2018).…”

Earthworms have a critical influence on the soil structure, forming aggregates and improving the physical conditions for the plant growth and nutrition uptake. Earthworms consume large quantities of organic matter such as agro waste, kitchen waste, nitrogen rich materials like cattle dung and excrete casts which have several growth promoters,enzymes which enrich the soil with bacteria and vesicular arbuscular mycorrhizae (VAM) beneficial for the plant growth.Vermiwash is a liquid manure collected from the compost unit after the passage of water through a column of worm action and is useful both as foliar spray or for soil application. In the present investigation an attempt was made to study the effect of vermiwash on the growth parameters of chilli plant Capsicum annuum. In plot 4 with vermiwash and drip irrigation technique maximum increase in growth parameters such as root length 11.0 cm, stem length 70.0 cm, number of leaves 120.0, side root length 05.0 cm leaf length 06.5 cm, leaf width 03.2 cm, number of flowers 46.0, number of chillies 43.0 were observed and established with nearly perfect correlation coefficient of 0.992. between root length and stem length.

“…Vermicompost was collected from CAPS Research Station and prepared using a method developed by Muktamar et al (2017). The chemical properties of vermicompost were 7.98% C, 3.06% N, 5.96% P2O5, 1.27% K2O, 1.79% Ca, 0.97% Mg, and pH of 5.47 (Muktamar et al, 2021).…”

Continuous use of synthetic fertilizer can lead to the accumulation of heavy metals in the soil. The use of organic amendment can reduce the solubility of heavy metals such as Pb and Cd in soil. The experiment was undertaken to determine the decline of soluble Pb and Cd in polluted soils treated with dairy cattle waste-based vermicompost. The study used two soil samples; Inceptisols collected from Air Duku Village and Entisol from Beringin Raya Village, Bengkulu, Indonesia. Entisols and Inceptisols contained 2.0 and 0.4 mg kg-1 soluble Pb and 0.7 and 0.8 mg kg-1soluble Cd, respectively. The samples were pretreated with either 100 ppm Pb or Cd. Vermicompost was applied at the rate of 0, 10, 20, and 30 Mg ha-1 on samples of Inceptisols and Entisol, arranged in Completely Randomized Design (CRD). The mixture was incubated for eight weeks. After the incubation ended, the soil sample was analyzed for soluble Pb and Cd using DTPA extraction before detection using Atomic Absorption Spectroscopy. The study resulted that the soluble Pb and Cd significantly reduced with vermicompost treatment, being the lowest was at the rate of 30 Mg ha-1. Furthermore, the decreased soluble Pb and Cd was more substantial in Inceptisols than Entisols. Soluble Pb in both soils was lower than Cd, suggesting a higher retention affinity of the former. This study summarizes that vermicompost at the rate of 30 Mg ha-1 effectively immobilizes Pb and Cd in contaminated soils.

“…The 10 DBP vermicompost application time allows microorganisms to carry out the decomposition process. According to Muktamar et al 2021 andRavendran et al 2016, the incubation process was carried out to enable microorganisms to proliferate and metabolize to degrade organic matter content into inorganic compounds that plants will absorb. Incubation of organic fertilizers could also increase soil pH (Siregar et al, 2017), increase available P and CEC, and decrease exchangeable Al and Al saturation (Pasaribu et al, 2018).…”

Vermicompost is an organic fertilizer containing essential macro and micronutrients for plant growth. This study aimed to determine the dose and time of vermicompost application to the shallot. The study was carried out at an altitude of 1054 meters above sea level in Air Duku Village, Selupu Rejang District, Rejang Lebong Regency, Bengkulu Province. A Split Plot Design with three replications was used in the study. The main plot was the time of vermicompost application, which was ten days before and during planting. Sub-plots were vermicompost doses of 0, 10, 20, 30, and 40 tons/ha. Vermicompost applied ten days before planting at a 40 ton/ha resulted in the tallest shallot shoot (36.60 cm) and the highest number of leaves (28.20). Vermicompost applied ten days before planting produced more shallot bulbs (4.46 bulbs), larger bulb diameter (19.18 mm), heavier bulb weight per clump (4.75 g), and heavier bulb weight per m2 (837.73 g) than vermicompost applied at planting. Vermicompost at a dose of 40 tons/ha resulted in 5.80 bulbs per plant, 18.96 mm bulb diameter, 4.63 g bulb weight per clump, and 1022.25 g bulb weight per m2, higher than the lower dose. Therefore, vermicompost could benefit as a source of plant nutrients, comparable to synthetic fertilizers in shallot production.
