Item Agrobiological characteristics of spelt wheat and intermediate wheatgrass in the Right-Bank Forest-Steppe of Ukraine(Ukrainian Journal of Ecology, 2020) Karpenko, V. P.; Poltoretskyi, S. P.; Liubych, V. V.; Adamenko, D. M.; Kravets, I. S.; Prytuliak, R. M.Estimation of spelt wheat and the species of intermediate wheatgrass by the main agrobiological indicators (calendar dates of the beginning of the main phases of plant development, plant height dynamics, dry mass accumulation, grain yield and protein content) compared to soft wheat was done. The index of stability of grain yield formation was determined. It was found that the main phases of development in spelt wheat occurred on average 10–15 days later than in soft wheat. Plants of intermediate wheatgrass in the first year of cultivation had slower growth. The main phases of development in plants of intermediate wheatgrass of the second and third year of growth occurred almost in the same time with soft wheat. It was established that spelt wheat and intermediate wheatgrass were significantly superior to soft wheat in plant height. In the earing phase, the height of these plants was on average more than 100 cm, which had to be taken into account when growing these crops. It varied from 25 to 42 cm in spelt wheat and from 29 cm to 57 cm in intermediate wheatgrass during the stem elongation phase depending on the weather conditions of the research year. This indicator ranged from 107 cm to 113 cm and from 96 cm to 117 cm, respectively, in the earing phase, and from 137 to 168 cm and from 107 cm to 196 cm in the phase of milk ripeness of grain. Plants of spelt wheat and intermediate wheatgrass had a high stability index of the formation of dry matter and grain yield. It should be noted that intermediate wheatgrass formed a significant vegetative mass even in the earing phase. The vegetative mass in spelt wheat was formed during the earing period – full ripeness of grain. These crops (spelt wheat – 22.1 0.4, intermediate wheatgrass – 22.4–24.6 0.2–0.5) were significantly superior to soft wheat (12.1 0.5) by the content of protein in grain, so it was recommended to involve them in the selection programs to create species with high productivity. However, spelt wheat (5.58 0.13) was less and intermediate wheatgrass (0.98–1.22 0.14–0.18) was the most inferior to soft wheat (8.03 0.27) in terms of grain yieldItem Agrochemical component of soft winter wheat cultivation technology(Saarbrücken, Germany: LAP LAMBERT Academic Publishing, 2021) Liubych, V. V.; Hospodarenko, H. M.; Polianetska, I. O.Estimation of spelt wheat and the species of intermediate wheatgrass by the main agrobiological indicators (calendar dates of the beginning of the main phases of plant development, plant height dynamics, dry mass accumulation, grain yield and protein content) compared to soft wheat was done. The index of stability of grain yield formation was determined. The publication of scientists of Uman National University of Horticulture includes works in the field of studying the quality of grain and grain products of cereals. This book will be useful to crop breeders working on new varieties of wheat, agronomists growing this important food crop, bread industry specialists, scientific and teaching staff, postgraduates and students of agricultural specialties and experts.Item Agrochemical component of soft winter wheat cultivation technology(Saarbrücken, Germany: LAP LAMBERT Academic Publishing, 2021) Liubych, V. V.; Hospodarenko, H. M.; Polianetska, I. O.The book provides a scientific substantiation and general formation patterns of formation of wheat grain quality depending on abiotic and biotic factors, selection and genetic characteristics of the variety and weather conditions. The peculiarities of productivity formation of different-ripening varieties of soft winter wheat depending on the fertilizer system in the field crop rotation are highlighted.Item Characterization of amino acid content of grain of new wheat varieties and lines.(Київ, 2018) Hospodarenko, H. M.; Karpenko, V. P.; Liubych, V. V.; Novikov, V. V.Aim. To determine the formation of bound amino acids in grain of new wheat varieties and its biological value. Methods. Field, physical-chemical, computational, analysis. Results. The differences in amino acid composition of new varieties and lines of wheat were analyzed. It was established that the highest content of essential amino acids was in the grain of the Kulundynka variety (5.18 %) or 2.5 times higher compared to the standard (2.99 %). Their content in the grain of soft wheat, obtained by the hybridization of Triticum aestivum L./Triticum spelta L., was 1.4–1.5 times higher compared to the control. The grain of the soft variety Kulundynka had the highest biological value as the score of essential amino acids was not de cient and the remaining varieties were de cient in 2–5 amino acids. Only methionine was de cient in the grain of soft wheat lines (AAS = 64– 74 %). Conclusions. The content of amino acids in soft wheat grain depends considerably on weather conditions, selective-genetic origin of the variety and the line. Glutamic acid, proline, and leucine were found to be most abundant. Out of nine samples of soft wheat tested, only the seed of the Kulundynka variety had a nonde cient amino acid score (91–298 %), and in the Pannonikus variety methionine was limited (49 %). The best balanced content of amino acids is present in the grain of non-spelt lines, obtained by hybridization of Triticum aestivum L. and Triticum spelta L., namely 7 and LPP 1314. The grain of these lines has a non-de cient amino acid score, more methionine (AAS = 64–74 %), and supplies human daily requirement in the best way. The grain has a high index of complex estimation and metabolization coef cient for essential amino acids.Item Microbiota in the Rhizosphere of Cereal Crops(Microbiological Journal, 2021) Karpenko, V. P.; Poltoretskyi, S. P.; Liubych, V. V.; Adamenko, D. M.; Kravets, I. S.; Prytuliak, R. M.; Kravchenko, V. S.; Patyka, N.I.; Patyka, V. P.Today, spelt wheat grain is used to produce high quality food. Intermediate wheatgrass is a promising crop for prairie restoration. One of the elements of biologization is the influence of growing crops on the microbiota of soil rhizosphere. The microbiota of spelt wheat and intermediate wheatgrass soil rhizosphere remains insufficiently studied. Aim. To study the number of individual groups of microbiota in dynamics in the rhizosphere of cereal crops (spelt wheat, intermediate wheatgrass) depending on the weather conditions and the phase of plants development. Methods. Classical microbiological, statistical methods were used in the work. In particular, the study of the number of microorganisms of different ecological and trophic groups (ammonifying, nitrifying, cellulolytic and nitrogen-fixing) was carried out according to generally accepted methods in soil microbiology. The reliability of the influence of factors was determined by the probability value «р» level which was calculated using STATISTICA 8 program. Results. The amount of ammonifying and cellulolytic microorganisms in the soil rhizosphere of spelt wheat is significantly higher compared to soft wheat. The rhizosphere microbiota amount of the intermediate wheatgrass on the 2–3 year of cultivation was more resistant to adverse environmental factors compared to soft wheat. The soil rhizosphere microbiota did not change a lot depending on the phase of plant development during the vegetation period of cereal crops (spelt wheat, intermediate wheatgrass). Conclusions. The formation of rhizosphere microbiota of spelt wheat and intermediate wheatgrass was first analyzed under the conditions of the Right-Bank forest-steppe of Ukraine. The conducted studies indicate the feasibility of growing and use of spelt wheat in breeding programs to create cultivars of soft wheat with higher activity of rhizosphere microbiota. The number of ammonifying, nitrifying and cellulolytic microorganisms of soil rhizosphere of intermediate wheatgrass was significantly higher compared to soft wheat during all growth stages. The conducted studies confirm the practical application of intermediate wheatgrass to preserve and increase soil fertility. Intermediate wheatgrass can be grown for up to three years in one field, as microbiological activity reaches its maximum developmentItem The prospects of production of perennial grasses in Ukraine(Saarbrücken, Germany: LAP LAMBERT Academic Publishing, 2021) Karpenko, V.
