Conducted By:

Department of Research Institute of Agricultural Science, KangWon University, Korea

Head Researcher:   Professor Kim, Dept of Practical Botany
Objective:   Following test was carried out to examine the growth promoting effect of Agri-Gro Bio-Stimulant in a garden crop.
Test Subject:   Yellow Spring Cabbage
Duration of Test Period:   3 months (April 1, 2002 – June 30, 2002)
Plot Arrangement:   3 Repetition of Randomized Block Design
Application Method:   Soil drench weekly basis after planting
Concentration of Agri-Gro® Bio-Stimulant™ in Drench Solution:   3 rates tested - 0.2%, 0.1%, 0.06%
Fertilization:   All plots fertilized once a week with (N, P, K, Ca, Mg, S)
Items Examined:   Measured leaf numbers and chlorophyll every ten days after treatment. Measured leaf length, leaf width, bulb diameter and fresh weight of cabbage including root during the final examination period.
