This series of published greenhouse trials (Ryang, Lim, & Kim, 1995) was conducted by the Institute of Agribiology, Academy of Agricultural Services in Pyongyang, Korea.
The trial was designed to look at the effects on yield and quality of some vegetable crops. The results found that the yields of spinach grown in glasshouses were increased by 10.4 – 24.8 % with the addition of EM. And the yields of Chinese cabbage and radish in field in autumn were increased to 23.5 - 57.9 % 38.8 - 47.2 %, respectively. Improvement of taste and nutrient value by increasing of vitamins, sugar, protein and amino acid was found with Elf treatment in vegetable crops.
