The aim of the research was to analyse the yield and grain yield components in four varieties of wheat cultivated on acid soil. The highest values of yield components and grain quality were established in the year with moderate temperatures and high precipitation in the vegetation year 2010/11. The KG 56S and Vizija varieties had the highest yield of grain, the highest number of plants and spikes per m2. The Perfekta variety showed the highest

Abstract:
Current trends in population growth suggest that global food production is unlikely to satisfy future demand under predicted climate change scenarios. Therefore, further improvements on wheat yield potential will be essential to meet future food demand. Thus, to further raise wheat grain yield it is critical to understand the physiological basis of grain number per m2 determination. Yield responsiveness to resource availability is usually related to grain number per m2 in most of grain crops, such as durum wheat.

Abstract:
This paper presents the results of two-year research (2015/16 and 2016/17) on impacts of different agro-technical measures to the yield components of four varieties of winter wheat (Nova Bosanka, Prijedorčanka, Orion and Evropa 90), grown on meliorated Deposol in the process of reclamation in the terchnogenic soil (Stanari lignite mine area). The aim of the research is to determine the impacts of years, different dosages of fertilizers (five treatments: N60+90P60K60, N60+40P60K60, N60+90P37K37, N60+40P37K37 and N0P0K0) and variety to quantitative properties of the spikes (spike length and grai

Abstract:
The results of the inheritance of grain number per main spike in F1 hybrids of winter barley under the conditions of the V.M. Remeslo Myronivka Institute of Wheat of NAAS are presented. Different types of trait inheritance were established depending on the combination of crossing. According to the type of positive overdominance (hp ≥ +1.00), 7 hybrid combinations of winter barley were selected. As genetic sources for increasing the grain productivity of plant, the variety KWS Tenor and the line Pallidum 5173 should be used as the maternal component.

Abstract:
The harmfulness of ergot on winter rye crops in the Kirov region depends to a large extent on the number of sclerotia in the ear, which leads to an increase in the contamination of the grain mass with sclerotia. It has been established that with an increase in ear infestation by 1 sclerotia, the number of grains decreases by 4.96 pieces, grain weight by 0.26 g, and weight of 1000 grains by 2.49 g

The researches results showed the positive the bacterium species Azotobacter chroococcum im-pact on winter wheat yield structure. Especially, the grain yield of Favoritka increased on 0,38 t/ha, or on 10 %; weight 1000 grains – on 2.9 g, or on 7,5%; the spike’s length-on 0,7 cm or on на 9,9 %; the grain’s quantity in one spike is on 2,3 pcs, or on 9 %; one plant’s weight-on 0,23 g, or on 5,6 %; the spike’s weight-0,17g, or on11%, one spike’s grain weight- on 0,4 g, or on 5,3 %.

Abstract:
To reduce financial risk and N losses to the environment, fertilization methods are needed that improve NUE and increase the quality of wheat. In the literature, ample attention is given to grid-based and zone-based soil testing to determine the soil N available early in the growing season. Plus, information is available on in-season N topdressing applications as a means of improving GPC. However, the vast majority of research has focused on wheat that is grown under N limiting conditions in sub-humid regions and irrigated fields. Less attention has been given to wheat in dryland that is water
