Chicken eggshells as a soil amendment and their relationship with the morphological response of mustard plants (Brassica juncea, L.)

The purpose of this study is to obtain objective information about the dosage of the use of chicken egg shells as a soil reformer in the sustainable cultivation of mustard plants. The research has been carried out at the Coronary Garden, Faculty of Agriculture, Syiah Kuala University from August to September 2021. The study used polybags in the form of experiments with a completely randomized design. The treatment tried was in the form of various doses of chicken eggshell flour (0, 5, 10, 15, and 20 g / stem), and the morphological response of mustard plants were measured in the form of; plant height; the number of leaves per plant; fresh weight; and the dry weight of the plant. To test the effect of treatment on the response variables of mustard plants using the ANOVA statistical test procedure, while to test the difference in the average value of plant responses using the Tukey HSD test at α 0.05. Mustard plants showed a positive morphological response to the administration of chicken shell flour as seen from plant height, the number of leaves and wet weight, and dry weight. Chicken eggshell flour as a soil enhancer contains macro and micro nutrients to increase the growth and yield of mustard rice fields. The use of chicken eggshell flour of 5 g / stem provides the best morphological response for mustard plants.
