ABSTRACT THE EFFECT OF GIVING AB MIX FERTILIZER, LEAVES BOKASHI AND URIN COW ON PAKCOY GROWTH (Brassica rapa L. subsp. Chinensis) WITH THE SYSTEM HYDROULIC DFT (DEEP FLOW TECHNIQUE) Fitri Kamelia Simbolon 1441011 Waste of cow's urine is wasted, will becomes livestock waste whish is very useful when used as liquid fertilizer for vegetable crops. Nutrients contained in urine were nitrogen 1.00%, 0.50% phosphorus and 1.50% potassium. The nitrogen content of liquid organic fertilizer acts as a constituent of protein, phosphorus and calcium plays a role in spurring division of meristem tissue, stimulating root growth and leaf development. so that this organic content will be used by plants for division, extension and differentiation of internal cells for hydroponic plants. Vegetables are horticultural products that are very popular with the community because they are full of nutrients that are useful for health. One type of vegetable needed by all levels of society is Pakcoy (Brassica rapa L. var. Chinensis). In addition, various types of plants can be planted with hydroponic systems because hydroponics is easy to do and does not require extensive land. The purpose of this study was to determine growth by using AB mix, bokashi leaves and cow urine. One-way analysis of ANOVA and Duncan with a significant level of α = 0.05. The results of the descriptive analysis test give significance that cow urine affects plant growth, leaf width, and root length. Key words: Cow urine, Hydroponics, Pakcoy (Brassica rapa L. var. Chinensis).
