The Effect of Liquid Organic Fertilizer (LOF) Made from Rabbit Urine and NPK Fertilizer on the Growth of Bok Choy (Brassica rapa L. Subsp. chinensis)

Fertilizer is one of the most important needs for plants. Fertilizing can be done by using inorganic fertilizers or organic fertilizers. Long term fertilizing without adding matter could potentially reduce soil fertility and lead to not optimal growth plant. This study aims determine effect liquid fertilizer (LOF) made from rabbit urine, NPK fertilizer, combination both on bok choy, best dosage choy. uses a Completely Randomized Design consisting 2 factors, dose urine LOF fertilizer; 4 levels each in triplicates. Data was analyzed ANOVA followed DMRT Test. The results indicates that application increases plant height, leaves number, leaf area, wet weight, dry chlorophyll total (a 5%) test shows applied enhancing parameter are 6 ml plus 0,4 gram 0,6 number total.
