Promising uncommon poaceous and leguminous fodder crops

The results of research (2016-2018) into productivity, adaptability and nutritional value of poaceous crops (forage millet, Sudan grass) and legumes (fodder beans, spring vetch, garden peas) are presented and analyzed. The research was conducted on meadow chernozem mealy-carbonate soil, light loam by granulometric composition, in the forest-steppe zone of Trans-Baikal Territory. Agricultural technology used for fodder crop cultivation was common for this area. The objects of the research were legumes (Sibirskiye forage beans, Novosibirskaya spring vetch, Holik garden peas), and poaceous varieties (Bystroe forage millet, Novosibirskaya 84 Sudan grass). The experimental work was carried out in accordance with the generally accepted guidelines for field experiments. All the forage crops under study have formed a fairly high productivity: the yield of green mass was 13.0-18.2 t/ha, dry matter – 2.6-3.2, feed units – 2.2-2.7 t/ha, digestible protein – 220-567 kg/ha, gross energy – 26.5-32.2 GJ/ha, with availability of digestible protein 100-210 g per one feed unit. Among leguminous crops, spring vetch and fodder beans had an advantage with the green mass yield of 13.3-15.0 t/ha, the amount of dry matter of 3.1-3.2, feed units of 2.6-2.7 t/ha, digestible protein 494–567 kg/ha, gross energy 32.0–32.2 GJ/ha, with availability of digestible protein of 190–210 g per one feed unit. Garden peas were inferior to spring vetch and fodder beans in yield by 2.3-13.3%, dry matter – by 9.6-12.5, feed units – by 3.8-7.4, digestible protein – by 4.9-17.1, gross energy – by 8.1–8.7%. Among poaceous crops, agrocenoses of Sudan grass had an advantage in productivity and nutritional value. They formed the yield of green mass 18.2 t/ha, the amount of dry matter 3.1, feed units 2.5 t/ha, digestible protein 300 kg/ha, gross energy 31.3 GJ/ha, with availability of digestible protein of 120 g per one feed unit. Fodder millet was inferior to Sudan grass in all respects by 12.0–26.7%, respectively.
