Abstract
The increased use of chemical fertilizers in agriculture has led to major environmental issues, such as soil acidification, water pollution, and increased nitrogen in the atmosphere. In addition to this, chemical fertilizers pose health risks to humans, including various diseases such as cancers and embryonic development issues (Ahmed et al., 2017). Biostimulants are organic fertilizers that have gained popularity in the past decade due to their abilities to promote various factors of plant growth and quality and because of their ecofriendliness. While research exists on the effects of individual biostimulants on plant growth, there are limited studies on combined biostimulant application, particularly on chitosan and garlic extract. The purpose of this study was to determine if chitosan and garlic extract are effective biostimulants that can increase root growth in Eruca sativa. It was hypothesized that the combined biostimulant application would result in the greatest root length in Eruca sativa when compared to the control and chitosan groups because the garlic extract would increase the root absorption of chitosan in the plants, leading to increased root growth. In order to perform this experiment, Eruca sativa plants were grown in three different groups, one control, one where chitosan was applied, and one where chitosan and garlic extract were both applied. The results of this experiment indicated that there was a significant difference in the root lengths after biostimulant application based on a one-way ANOVA test with an alpha value of 0.05, with the p-value being <0.0001, meaning the null hypothesis was rejected. Therefore, there was significant evidence to suggest that combined garlic extract and chitosan biostimulant application is effective at increasing root length, a parameter of plant growth and quality.
