Abstract

The purpose of this research is to determine the concentration of organic nutrient solution produced by the process of Han Kyu Cho and Atsushi Koyama (1997) from soybean residues to grow lettuce and collard greens by hydroponic method.  Accordingly, organic solutions with the main components including total nitrogen: 1968.23 mg1, P2O5: 167.53mg/l, K2O: 420.91mg/1 were investigated at dilution concentrations from 5-20 times.  Research results show that the dilution concentration is suitable for the growth of lettuce and broccoli from 10 to 15 times, with this concentration range, the Bix level of organic nutrients used by vegetables is higher than that of Knop solution  from 2.2 to 2.8 % for salad vegetables, 0.5 to 1.3 % for sweet vegetables, especially NO3 content in commercial vegetables using organic nutrients is 3 times lower than  Knop solution
