The influence of amorphous silicon dioxide "Kovelos" on yield and growth characteristics of some crops

In the study the influence of amorphous silica “Kovelos” and its colloidal solution on shoot growth, physiological characteristics and crop yield of some crops have been investigated. The preplant treatment by means of amorphous silicon dioxide powder of 50 mg/g demonstrated growth-promoting effect on the “Alfa” pea, “Izyashchnyj” cucumber and “Favorit” maize sprouts. The preplant powdering of 50 mg/g amorphous silicon dioxide of the pea “Alfa” seeds increased the root and shoot length to 1.7 and 2.8 times respectively as compared to control. The preplant treatment of amorphous silica resulted to the crop yield increase of “Losinoostrovskaya13” carrot, “Aehronavt” squash, “Vinogradnaya grozd’” cherry tomatoes. The preplant treatment of the potato tubers (Zhukovskij rannij variety) of amorphous silicon dioxide powder of 3 g/kg increased the yeld by 13.8% as compared to control. The substance demonstrated a stimulating effect on potatoes growth characteristics and photosynthetic yield.
