Yield and feed qualities of triticale mixed with high-protein crops

Abstract

The results of field and laboratory studies on the cultivation of triticale mixed with high-protein crops are presented. The study was carried out during the period of 2015-2017 on meadow chernozem mealy-carbonate soil, light loam by granulometric composition, in the forest-steppe zone of Trans-Baikal Territory. The assessment of triticale in single-species and mixed crops for adaptability to growing conditions and yield is given. Economically valuable traits of these crops are shown. The possibility of increasing the yield and feed qualities of agrocenoses by sowing triticale with highprotein crops was established. On average, over the years of research, mixed crops outperformed single-species triticale agrocenoses in terms of yield and feed quality, green mass by 1.6-1.9 times, digestible protein by 2.6-3.7 times. In mixed crops, triticale with fodder beans provided the best results, the yield of green mass was 40.5 t/ha, dry matter – 5.70 t/ha, feed units – 4.67 t/ha, digestible protein – 785 kg/ha, exchange energy – 57.6 GJ/ha, availability of digestible protein per one feed unit – 168 g. Triticale crops mixed with fodder beans increased productivity compared with singlespecies crops in terms of green mass yield by 1.3-1.9 times, dry matter by 1.4-1.9 times, feed units by 1.4-2.0 times, gross energy by 1.5-2.0 times. All crops are resistant to drought and lodging. The absence of pest and disease infestation in triticale was noted.
