Litter invertebrate communities in pine forests of different age (cut, six-year-old, 45-, 62-, and 105-year-old) in the Baranivka area of Zhytomyr Polissya (northwestern part of Ukraine) were studied. Samples were collected in April, August, and November 2011. 99% of extracted invertebrates were represented by mites (Acari) and springtails (Collembola). With forest age, the following tendencies were observed: mean absolute density of mites, springtails, and all litter-inhabiting animals increased; relative abundance of mites increased, but relative abundance of springtails decreased; taxonomic richness of invertebrate communities increased. In all samples, the most represented taxon was suborder Oribatida. The most diverse litter invertebrate community was in the 45-year-old forest. Similar compositions of invertebrate community were in the 45-, 62-, and 105-year-old forests as well as the cut and six-year-old ones.

The article is devoted to the analysis of historical, cultural, and architectural importance of Miklouho-Maclay park, a monument of landscape art. It examines the archive data about the family of the famous traveler, ethnographer, anthropologist Mykola Mykolayovych Miklouho-Maclay who lived in Malyn (Zhitomir district Ukraine) at the end of XIX and the beginning of XX century, his contribution to the development of landscape art. It is shown that the park contains 57 species of arboreal-shrub plants including 34 species of trees, 22 shrubs, and one shrubbу liana. 23 of them (40%) are introduced species. The author offers the direction of parkland reconstruction and points out recommendations on territory zoning.

Breeding work on Ribes species has been started at the National University of Life and Environmental Sciences of Ukraine in Kyiv since 1984 by Petro Sherenhovyj. The breeding programme has been focused on fruit quality, yield, resistance to diseases and pests, as well as on adaptive responses to environmental conditions. As a result of the long-term work, 18 new cultivars were included in the State Register of Plant Varieties of Ukraine in 1999– 2016. The aim of this paper is to describe these varieties: 10 blackcurrant (‘Dochka Vorskly’, ‘Hovtva’, ‘Pam`yati Leonida Mykhalevskoho’, ‘Universytetska’, ‘Aspirantska’, ‘Didorivska’, ‘Poltava 584’, ‘Petrivska’, ‘Yuvileina Sherenhovoho’, and ‘Leleka’), 5 redcurrant (‘Kyianochka’, ‘Poliana Holosiivska’, ‘Buzhanska’, ‘Malva’, and ‘Olha’), 1 whitecurrant (‘Lebidka’), and 2 gooseberry (‘Vasylko’, and ‘Tikych’). The varieties described give farmers and scientists the best knowledge about these cultivars with good level of commercial traits, suitable for dissemination in Ukraine.

Triticale (×Triticosecale Wittmack) is a promising cereal crop that has a number of economically valuable properties that are absent in wheat (Triticum aestivum L.). The research was conducted at Uman National University of Horticulture (Ukraine) in a long-term stationary experiment, founded in 1964. The aim of the work was to study the influence of long-term application of different fertilizer systems (mineral, organic and organo-mineral) on the yield and grain quality of spring triticale. It has been established that in the conditions of high air temperature and soil moisture deficit, mineral and organo-mineral fertilizer systems have an advantage. In sufficient wet conditions, all studied fertilizer systems are highly efficient. Spring triticale (Kharkiv Hlibodar variety) has a high reaction to fertilizers, as grain yield increases from 6.3–6.6 to 9.0–9.5 t haE−1 (р≤0.05). Mineral and organo-mineral fertilizer systems have the greatest effect on protein content. In conditions of sufficient moisture, all levels of mineral and organo-mineral fertilizer systems significantly increase the protein content in spring triticale grain. In arid conditions, saturation of crop rotation area with N90P90K90 (M2), N135P135K135 (M3) and Manure 9 t +N46P68K36 (OM2), Manure 13.5 t + N69P102K54 (OM3) is preferred. It should be noted that spring triticale is quite reactive with fertilizers, as the protein content increases from 13.2–14.0 to 15.2–16.0% (р≤0.05) depending on the fertilizer system. The high influence of fertilizer system and year factors on yield and protein content in triticale grain has been established. It should be noted that spring triticale grain yield varies most from the weather conditions of the growing season.

With this issue of 2009, we bring 52 proceedings of the 98, which started life as presentations at the Annual 15th International Scientific Conference Research for Rural Development 2009 held at the Latvia University of Agriculture, in Jelgava, on 20 to 22 May 2009. In the retrospect of four months later, we can count the Conference as a great success. The theme - Research for Rural Development - attracted participation of 321 researchers with very different backgrounds. There were 4 presentations from Ukraine, 3 from Sweden, 2 from Belarus, 3 from Estonia, 1 from Belgium, 1 from India, 1 from Turkey, 10 from Lithuania and 64 from Latvia. Four independent reviewers estimated each report. The proceedings of the Annual 15th International Scientific Conference Research for Rural Development 2009 is intended for academics, students and professionals researching in the area of crop production, animal breeding, agricultural engineering, agrarian and regional economics, food sciences, veterinary medicine, forestry, wood processing, water management. The proceedings will also be useful for researchers in educational sciences.
