Effect of Vermicompost and Nitrogen Fertilizer on the Growth and Production of Aloe Vera

Purpose: The effect of vermicompost and nitrogen fertilizers on the growth and production of Aloe vera were conducted using factorial based on Randomized Complete Block Design (RCBD).

Background: Vermicompost can be used in sustainable agriculture to support growing populations by increasing water holding capacity, nutrient supply, high porosity, adequate ventilation and drainage, and production of plant hormones that have beneficial effects on seed germination.

Methods: According to the RCBD method, treatments were included: four levels of vermicompost (V0: Control, V1: 75, V2: 150 and V3: 200 g per pot) and four levels of nitrogen fertilizer (N0: control, N1: 500, N2: 1000, and N3: 1500 mg per pot) using urea.

Results: The results showed that application of 150 g of vermicompost and 1000 mg of nitrogen had the highest effect on growth traits, and application of 200 g of vermicompost and 1500 mg of nitrogen had the greatest effect on sucker characteristics, so that the highest number of suckers was obtained by using 200 g of vermicompost and 1000 and 1500 mg of nitrogen. However, simultaneous application of 150 g of vermicompost and 1000 mg of nitrogen had the greatest effect on plant height, number of leaves, and leaf diameter, and treatment with 200 g of vermicompost and 1500 mg of nitrogen had the greatest effect on the number of suckers, stem weight, number of leaves, sucker height, total biomass and Aloin content.

Conclusions: Therefore, simultaneous use of vermicompost and nitrogen fertilizer in Aloe vera cultivation plays an important role in the production and enhancement of sucker and plant yield.
