This research was implemented in the greenhouse at the Experimental Garden of the Faculty of Agriculture Universitas Islam Sumatera Utara, Sub-distric Gedung Johor, Medan Johor District, Medan City, North Sumatra Province. This research was implemented from November to December 2020. This study aims to determine the effect of concentration of AB Mix and ZPT solutions on the growth and production of mustard greens. This study used a completely randomized design (CRD) with two treatment factors the concentration of AB Mix solution and ZPT application. The first factors, the concentration of AB Mix solution consisting of 3 levels: K0 = control, K1 = 550 ppm, K2 = 1100 ppm. The second factor was giving ZPT the earliest in 3 levels: Z0 = control, Z1 = 0.5 ml, Z2 = 1 ml. The parameters observed were plant height, number of leaves, leaf length, leaf width, wet weight and dry weight. Its is know from the results concentrations of AB Mix solution significantly affected plant height, number of leaves, leaf length, leaf width, wet weight and dry weight. Giving of ZPT had a significant effect on leaf width but had no significant effect on plant height, number of leaves, leaf length, wet weight and dry weight. The interaction of AB Mix solution concentration and ZPT giving had no significant effect on the growth and production of mustard greens.
