In spite of the low grain yield they produce, the hulled wheat have become even more important in recent years because of their resistance to negative environmental conditions and healthy nutritional content. The research was carry out in order to comparison the yield and yield characteristics of durum (Kiziltan-91 and C-1252), hulled (Einkorn and Emmer) and bread wheat (Tir) varieties in Isparta ecological conditions in 2013-14 and 2014-15 vegetation periods. In both years, the highest grain yield was obtained in Kiziltan-91 variety (3992 and 3758 kg ha-1 respectively). The grain yield of hulled wheats in the first year (Einkorn 1269 kg ha-1, Emmer 2125 kg ha-1) was around Turkey averages. However, grain yield decreased of commercial wheat varieties due to the negative effect of high amount of rainfall in June in the second year, but considerably increased in (Einkorn 2150 kg ha-1, Emmer 2533 kg ha-1). N uptake was found to be lower in the than durum wheats. In terms of grain protein content, the highest values were obtained in Emmer variety (16.4%-15.3%).

The article focuses on the impact of different dairy management types on quality characteristics of organic and conventional milk. The study was conducted during 9 months (spring-autumn), raw milk samples were collected from organic and conventional dairy farms from two Ukrainian regions. The milk samples were analyzed for dry matter, total protein and non-protein nitrogen, ammonia content and values of stable isotopes 13С/12С were measured in fat and milk protein fractions. The values of dry matter, total protein, true protein and non-protein nitrogen content do not represent a statistically significant effect of farming type. The values of ammonia content, ammonia/non-protein nitrogen and ammonia/total protein ratios were statistically significant and reflected the impact of farming type which is, probably, linked with different protein content in cows’ diet. Conversion of some parameters on the dry matter allows more precise differentiation among types of milk, including statistically significant differences (e.g. total protein and ammonia content). The values of δ13C in fat fraction (-26.00‰) and protein fraction (-22.89‰) of organic milk were statistically significant differed in comparison with conventional milk (-23.14 ‰ and -19.15‰ respectively), due to the high amount of maize in the diet on conventional farm. The values of Δδ13C also were statistically significant: 3.99‰ in conventional milk and 3.11‰ in organic. It was established that conventional milk has a greater range of the different parameter seasonal variations than organic milk.
