Effect of Various Types of Liquid Organic Fertilizer on Growth and Yield of Mustard Greens (Brassica junecea)

Abstract

This study investigated the impact of liquid organic fertilizer (POC) application on the vegetative growth of various types of mustard plants, focusing on parameters such as plant weight, plant height, and number of leaves. The results showed that the application of POC significantly enhanced these growth parameters compared to treatments without POC. Among the POCs tested, formulations derived from organic materials such as onion waste, vegetable scraps, and eggshells demonstrated their effectiveness in supporting mustard plant growth. POCs supply essential macro- and micronutrients, as well as organic compounds which are crucial for improving plant physiological processes. Specifically, onion waste POC yielded the highest plant weight, while vegetable and eggshell POC contributed significantly to plant height and the number of leaves. The findings underline the importance of POC as an alternative, eco-friendly fertilizer capable of boosting mustard plant productivity during the vegetative growth phase. These results highlight the potential for POC to replace or supplement synthetic fertilizers, offering a sustainable solution to enhance crop yields while promoting soil health. Future research could explore optimizing POC formulations and application methods for broader agricultural use.
