Summary. Purpose of study was to develop effective methods of treatment of winter triticale variety Izhevskaya 2, that will cause the yield of seed with good quality. Researches were carried in 2012 and 2013 on the sod-podzolic medium loam soil. It was studied: foliar feeding (Carbamide N20 – in the phase of full earning, Terraflex 17+17+17 – in phase of booting and of full earing), spraying of crops with growth regulators (CCC 750 and Moddus at the beginning of autumn tillering and in the phase of booting). On the productivity of a winter triticale growth regulators strongly affected. The greatest input was obtained by spraying CCC 750 (increase at 0,33...0,42 t-ha in average among the variants of the experiment). The combined use of a growth regulator CCC 750 while the spring period and foliar Terraflex 17+17+17 in the phase of full earing increased the yield of grain and seeds up to 4,40 t/ha (increase at 0,36...1,33 t-ha in comparison with other variants) and 3,64 t-ha (increase at 0,39...1,26 t-ha in comparison with other variants), accordingly. Effect of Moddus treatment was at the level of control variant. Foliar feeding Carbamide N20 and spraying with growth regulators in comparison with the autumn using in the spring reduced energy of germination at 8,9...11,6%. In average during the period of researches the higher parameter of seed’s force growth was indicated while spraying crops with CCC 750 and foliar feeding Terraflex 17+17+17 in the phase of full earing (65,0%) and spraying Moddus and foliar feeding of Carbamide N20 (74,0%). Foliar feeding and spraying of crops with growth regulators are most effective in drought conditions and provides the formation of seeds with a higher germinative capacity and growth force.
