Evaluation of Nutrient-Rich Growing Media for Eco-Friendly Basil Production

Abstract

To optimize the quality and quantity of basil cultivars, this study investigated four varieties of nutrient-rich growing media compared with chemical fertilizers at the recommended dose in the soil-grown system, and commercial growing media (control) for producing holy basil and Genovese basil under greenhouse conditions. The experiment used a completely randomized design (CRD) with six treatments and five replications. With greater levels of chlorophyll, T3 and T4 growing media, consisting of top soil, filter cake, long-term/short-term composted chicken manure, coconut coir dust, and rice husk ash at a ratio of 3:2:2:1.5:1.5 v/v, produced the largest fresh yield when used for holy basil and Genovese basil productions, respectively. However, the net profit margin showed no discernible variations from T3–T5 and T2–T6 growing media, respectively. Nevertheless, T3 or T4 and T4 growing media were recommended for holy basil and Genovese basil production, respectively, based on highest productivity and intricacy of preparation, while also ensuring that the product retains its quality in terms of antioxidant bioactive components. In addition to maintaining the biomass of basil plants’ productivity even when they are cultivated in appropriate growing media, Genovese basil needs to be fertilized with organic fertilizer, like chicken manure, following the fifth or sixth harvesting period. Holy basil should be harvested after the fourth harvest period. © 2025 by the authors.
