The effect of foliar fertilization on yield and quality of American ginseng roots (Panax quinquefolium L.)
In a four-year-lasting field experiment the effects of foliar fertilisation with Mikrosol U and Ekolist Standard (in concentration of 1.5%) on yield and quality of American ginseng (Panax quinquefolium L.) roots were studied. It was proved that both preparations had a slender influence on roots’ length and diameter in the first year of vegetation. However, in the next three years of cultivation their positive effects on roots parameters were observed, resulting in significant yield increase. Raw material from plots sprayed with foliar fertilizers was characterized by better healthiness and higher active substances content. From two preparations concerned, Mikrosol U appeared to be more effective.
