Despite technology being developed to address the food shortages due to increasing population, current methods of cultivating crops are not sufficient. Scientists are addressing this issue by researching biostimulants that stimulate plant growth without harming the environment and researching the use of hydroponics, a way of growing crops without soil. The purpose of this study was to combine the use of essential oils and growing methods (hydroponics and soil) and measure its impact on the height of E. sativa. It was hypothesized that if E. sativa was grown hydroponically with added Rosmarinus officinalis (REO) and Trachyspermum ammi (TEO) over time, it would demonstrate greater growth because manipulating these aspects would directly impact the plants’ development and nutrient uptake. A 0.7% spray mixture of REO and of TEO was added to different sets of plants every five days in both the soil and hydroponic environments, and the height of the plants were measured each time. The results of the one-way ANOVAs (comparing the two environments) and z- and t-tests (comparing REO, TEO, and no treatment in the environments) suggest that there were no significant differences between the treatment of the oil used and the environment in which the plants were grown. Thus, it was concluded that there is not sufficient evidence to suggest there is a difference between the height of the E. sativa exposed to essential oils and those not exposed to essential oils in soil or hydroponics.
