EFFECT OF SOWING METHODS ON SEED YIELD OF WINTER TRITICALE IN MIDDLE PREURALYIE
The purpose of research is to develop methods of sowing winter triticale that will provide high quality seeds. Studies were carried out in 2012 and 2013 on the sod-podzolic medium loam soil. Methods of sowing (ordinary soldier, wide range and two-line banded) and seeding rates (6 and 3 million pcs -ha) were studied for two varieties of winter triticale - Izhevskaya 2 and Zimogor. Seed production of Izhevskaya 2 at crop two-line banded and seeding rate of 6 million pcs -ha was 3,06 t -ha, that exceeded other methods of sowing with the same sowing seed rate at 0,29 and 0,30 t -ha. Seed yield of variety Zimogor for the same combination of sowing methods was 2,89 t -ha, it was higher by 0,50 and 0,67 t -ha. The largest seeds of Izhevskaya 2 formed in a ordinary soldier method and seed rate of 3 million pcs -ha (mass of 1000 grain - 41,9 g), Zimogor - at the same seeding rate and wide range method (mass of 1000 grain -43,1 g). Multiplication factor of Izhevskaya 2 for wide range sowing method and a seeding rate of 3 million pcs -ha increased in a comparison with the ordinary way of planting and seeding rate of 6 million pcs -ha from 11,7 to 25,2; Zimogor - from 9,2 to 21,6. Varieties of winter triticale Izhevskaya 2 and Zimogor for grain and seed purposes is advisable to sow two-line banded with a seeding rate of 6 million pcs - ha. In order to increase the multiplication factor in a accelerate breeding seed it is most optimal to use wide range sowing method with row spacing of 30 cm and a seeding rate of 3 million pcs -ha.
