The role of foliar nutrition in the production process of soybean agrophytocoenoses and the formation of seeds germination ability

The field experiments in 2007-2011 carried out in the leached extra-potent low-humus chernozem of VNIIMK (Krasnodar) aimed at studying of foliar nutrition of soybean variety Vilana by nitrogen fertilizers (ammonium nitrate and carbamide) in a dosage of 10 kg/hectare and by compound fertilizer Master (2 kg/ha) have determined the efficiency of spraying by Master in a seed-filling period which considerably increased productivity (by 0.08 t/ha), protein (by 22 kg/ha) and oil (by 14 kg/ha) performance of agrocoe-nosis. The ammonium nitrate nutrition had the biggest positive impact on the accumulation of protein in seeds. The foliar nutrition by proven fertilizers accelerates the process of seeds ripening and increases sowing qualities of seeds, especially under double spraying of crops.
