Sažetak
The problems of introduction into practice of intensive oats cultivation technologies in the North-Eastern part of the Forest-Steppe of Ukraine have been considered. The oats plant yield capacity depends on mineral nutrition optimization. It was defined that hulless oat cultivars have more expressed response level of yield capacity on pre-sowing treatment with composition of Diazophyt and Microhumin bacterial fertilizers, that allows to reach closer to the level of hulled oat yield. The highest crop yield (for all cultivars) provided by combination of pre-sowing treatment with Diazophyt + Microhumin composition and application of N60P60K60 with foliar nutrition in tillering and panicle forming phase by Nutrivant Plus (2 kg/ha) + Urea (46.2%) 30 kg/ha. The maximum additional yield was fixed in Salomon cultivar with presowing Diazophyt + Microhumin treatment (+0.73-0.75 t/ha). Vegetative development and yield capacity of oats cultivars in the experiment revealed the group reaction dynamics on pre-sowing treatment, doses and ways of fertilizer application under conditions of the North-Eastern Forest-Steppe of Ukraine. The oat cultivar reaction specifies on optimization of zonal growing technologies for hulled and hulless cultivars. Thus, it is considered the possibility of increasing crop yield by improving of cultivation technology separately in the context of hulless and hulled groups of cultivars.
