The efficiency of soybean foliar application of microfertilizers in leached chernozem of the Western Ciscaucasia

The results of research of 2011-2013 on the effect of application of micronutrients (solubor DF in a dose of 1 kg/ha, kelik boron - 0.3 l/ha, ammonium molybdate - 0.1 kg/ha, kelik molybdenum - 0.3 l/ha, aquamix 0.1 kg/ha, kelik mix 0.3 l/ha) in nutrition of vegetative plants on the seed productivity, oil yield and protein of soybean variety Vilana determined that the most effective method is a foliar nutrition of soybean plants with aquamix, ammonium molybdate, and kelik mix at the stage of early flowering, which contributed to increase of productivity by 0.21-0.23 t/ha, of protein yield by 0.10-011 t/ha and of oil yield by 0.03-0.04 t/ha in comparison with control without fertilizer.
