Current Science Research Bulletin

Shallot (Allium cepa L.) is an economically and nutritionally significant horticultural crop, widely cultivated in Indonesia and essential for both household consumption and the culinary industry. Rising population and the expansion of the food sector have increased demand for shallots, highlighting the need for sustainable and stable production. Crop productivity is influenced by multiple factors, notably varietal selection and nutrient management. Each shallot variety exhibits distinct physiological traits and environmental adaptability, which directly affect growth performance and yield potential. Liquid organic fertilizer (LOF) has emerged as a promising strategy to enhance soil fertility, stimulate microbial activity, and provide essential nutrients in readily available forms for plant uptake. Its application can improve vegetative growth, bulb development, and overall yield; however, responses may vary depending on both the concentration of LOF and the specific shallot variety. Despite the recognized benefits, limited research has examined the combined effects of different shallot varieties and LOF concentrations under field conditions in Indonesia. This study aimed to evaluate the influence of selected shallot varieties and varying LOF levels on plant growth and yield, and to identify potential interactions between these factors. Results from this investigation are expected to inform optimal cultivar and fertilization strategies, supporting sustainable shallot production, enhancing crop productivity, and providing practical guidance for farmers and policymakers. The findings contribute to improving resource use efficiency, maintaining soil health, and promoting economically viable and environmentally sustainable horticultural practices.
