The formulation of chicken eggshell waste with market compost to increase the yield green mustard (Brassica juncea L.). Aims find best and environmentally friendly organic fertilizer formula improve some soil chemical properties. This research is a pot experiment in greenhouse, using simple randomized block design consisting 7 combinations. Fertilizer formulas that were tried were: F0 (without treatment), F1 = (100 kg shell + 10 tonnes compost), F2 (200 8 F3 (300 6 F4 (400 4 tons F5 (500 shells 2 F6 (600 0 each treatment was repeated times. parameters observed included: maximum plant height (cm), fresh weight at harvest, oven dry weight, pH, C-organic content, CEC Ca content harvest. data analyzed statistically, tested for variance. If effect had significant, then continued 5 % Duncans test. results this study indicate has significant on growth, plants, as well changes properties such as: C-organic, CEC, content. obtained (9.55 g), followed by (9.37 (9.18 g) per pot. While highest (36.31 me 100 g-1) 7.52 g-1. from found treatment.
