Abstract
The article provides the results of three year (2017-2019) study of the effect of pre-sowing treatment of seeds and foliar fertilizing on productivity and seed qualities of winter triticale varieties (×Triticosecale Wittmack.) Izhevskaya 2 and Zimogor. The research was carried out in the conditions of the Udmurt Republic. Pre-sowing seed treatment was done with fungicide Vial TT, compound fertilizer Agree’s Forsazh and plant growth stimulant Mival-Agro in their pure form, with tank mixtures containing Vial TT fungicide, and with mineral fertilizer Emix. Foliar feeding with Agree’s Nitrogen Potassi-um compound fertilizer was done once during the phase of spring tillering and twice - during the phases of spring tillering and full heading. Pre-sowing seed treatment combined with foliar fertilizing provided an increase in yield productivity of Izhevskaya 2 variety seeds by 0.07-0.55 t/ha (or 3-24 %), of Zimogor variety – up to 0.27 t/ha (or up to 11 %). The techno-logical practices promoted the increase in the laboratory germination of seeds by varieties – 1-2 % (control 91 %) and 2-3 % (control 88 %), respectively, germinative power – 2-4 and 1-2 % (control 93 %), respectively, degree of seedling development in both varieties – by 0.1-0.3 points (control – 4.5 and 3.7 points). The highest productivity of Izhevskaya 2 variety seeds (2.85 t/ha for 3 years on the average) has been obtained by pre-sowing treatment of seeds with Agree’s Forsazh and foliar fertilizing during the phase of spring tillering that is higher than in the control variant by 0.55t/ha (or 24 %). The increase in yield productivity of winter triticale Zimigor seeds up to 2.81 % (addition to the control is 0.24t/ha or 11 %) was promoted by pre-sowing treatment of seeds with Agree’s Forsazh regardless of multiplicity of foliar fertilizing. The seeds obtained were characterized by high sowing qualities of seeds: the germinating energy of Izhevskaya 2 variety seeds was 85 %, of Zimogor variety – 82 %, the laboratory germination – 93 % and 92 % , respectively, the germinative power – 97 % and 94-95 %. Double foliar fertilizing with Agree’s Nitrogen Potassium combined with pre-sowing treatment with Vial TT, Mival-Agro and their tank mixtures showed high effectiveness in Zimogor variety. Seed productivity in both of these variants was at the same level (2.73 t/ha). The above-mentioned practices can be successfully used when producing winter triticale seeds.
