Impact of Vermicompost Application on Soil Health and Yield of Eggplant (Solanum melongena L.)

a field experiment was conducted in a clayey soil to evaluate, the response of some physic-chemical properties of soil, some macro and micro-nutrients availability, plant yield, vegetative growth, some macro-micronutrients uptake and crop yield of eggplant (Solanum melongena L.) to the applications of different rates of vermicompost. Also, in this work, the effects of vermicompost on soil physic-chemical properties as well as the yield and vegetative growth of Solanum melongena L. were compared with the 100% mineral fertilizers and untreated soil (control). Vermicompost addition in three different dosages (10, 20, and 30 Mg ha-1. The soil chemical and physical properties, some macro and micronutrients availability, fruit weight, length, and diameter, as well as some macro and micronutrients uptake were measured after harvest. Vermicomposting significantly altered the properties of the soil and the growth of Solanum melongena L. The treatment 30 Mg ha-1reflects the greatest increase in soil organic matter, available nitrogen, phosphorus, and potassium by 47.50%, 77.01%, 109.18% and 37.50%, respectively. According to the findings, the values of EC and pH were enhanced. Vermicompost as an organic manure enhanced the vegetative growth, production and qualities of eggplants in the of tested soil in usual conditions.
