EFFECT OF FOLIAR APPLICATION AND GROWTH REGULATORS ON PRODUCTIVITY OF WINTER TRITICALE ‘IZHEVSKAYA 2’

The variety ‘Izhevskaya 2’ possesses such traits as high winter resistance, regenerative ability, ecological plasticity, grain and green mass productivity. To realize the variety potential it’s necessary to apply a cultivation technology adapted to definite agro ecological conditions. The article gives the results of long-term researches (2010-2013), the purpose of which was to develop some effective methods of plant care, promoting productivity increase of winter triticale ‘Izhevskaya 2’ in the Middle Pre-Urals. In a three factor experiment we studied the effect of a foliar application of carbamide (N20) in a phase of a complete earing on grain productivity. Then we studied the effect of application of a complex fertilizer Terraflex 17+17+17 (15 kg/ha) together with growth regulator TseTseTse 750 (1,5 l/ha) in a phase of a stem elongation and a complete earing on grain productivity. At last we studied the effect of application of Moddus (0,4 l/ha) in a phase of autumn earing and a stem elongation on grain productivity. We found out that a foliar application of a complex fertilizer Terraflex 17+17+17 and a growth regulator TseTseTse 750 in a phase of a complete earing had a significant effect on productivity of winter triticale ‘Izhevskaya 2’. These methods increased the crop productivity due to ear productivity. Under unfavourable conditions the growth regulators TseTseTse 750 and Moddus increased winter resistance, and promoted increase of density of productive stems in the period of spring earing and active growth in dry weather
