Field And Laboratory Conditions

Establish changes in the indicators of economic and energy efficiency of growing different varieties of clover for fodder purposes, depending on the methods of sowing, inoculation of seeds with nodule bacteria and fertilizers. Methods. Field and laboratory - for research in the field and laboratory conditions, analytical - to determine the chemical composition of the dry biomass of meadow clover, calculated - to determine the indicators of economic and energy efficiency. Growing meadow clover for fodder purposes on chernozems of typical low-humus northern part of the Right-Bank Forest-Steppe of Ukraine is profitable. Regardless of the elements of technology, it provides 14962-23743 UAH of net profit with a profitability of 88-259 % and the cost of 1 ton of feed units – 1415-2662 UAH and crude protein – 5363-10265 UAH, payback of energy consumption per 1 ha gross energy (KEE) – 6.2-9.0 and the output of 1 ha of exchange energy (BEC) – 3,2-4,6, as well as energy costs per 1 ton of feed units 2.86-4.20 GJ. The best indicators of economic and energy efficiency of meadow clover cultivation are provided by the Typhoon variety by inoculation of seeds with nodule bacteria on a background without fertilizers. Additional application of P60K90 or N60P60K90 on the background of inoculation, which is necessary to maintain soil fertility, worsens them, reducing the net profit by 3486-5943 UAH per ha.

Goal. The purpose of the research was to determine the influence of meteorological factors on potato yield in the conditions of the Right Bank Forest-steppe of Ukraine. Methods.Field, analytical and statistical. Results.It was established that among the mid-range varieties Divo stands out with a yield of 42.3 t/ha, Malin white – 39.8 t/ha, and Legend – 37.1 t/ ha. The most favourable weather and climatic conditions for the production of potato tubers were for the Divo 2011 variety with a yield of 45.9 t/ha and 2013 – 45.1 t/ha. For the Legenda variety 2016, the yield of potato tubers is 40.6 t/ha and 2017 – 43.2 t/ha. Malin White 2013 is 41.4 t/ha and 2017 42.1 t/ha. The average varieties of potatoes showed a slightly lower yield on average over the years of research. However, among the varieties is allocated Nadiyna – 40.3 t/ha, Slovyanka – 37.2 t/ ha and Vera 33.8 t/ha. Among the years, the most high-yielding for the Vera variety was 2016 with a yield of 36.6 t/ha and 2017 year – 37.8 t/ha. Varieties Slovyanka and Nadiyna 2011 and 2012 with yields of 42.6 and 44.3 t/ha and 46.5 and 45.3 t/ha, respectively. Characterizing the yield of potato tubers of medium-late varieties over the years of research, there was a decrease in this indicator compared with medium-early and middle-aged varieties. However, the high yield of the varieties of Dar is allocated – 40.0 t/ha, Alladin – 33.6 t/ha and Oxamit 31.3 t/ha. Among the years, the most favourable ones were: for Oxamit and Alladin – 2011 – 33.5 and 36.5 t/ha, and 2017 – 34.1 and 36.4 t/ha, respectively. Favourable years for harvesting varieties were 2011 and 2012 with yields of 45.7 and 45.8 t/ha. Thus, the highest yield of potato tubers on average over the years of studies of medium-early varieties of 41.2-43.3 t / ha were provided by weather conditions of 2011 and 2017 years, medium-ripe varieties 41.0-41.1 - 2012 and 2011, medium- late 37,6-38,5 t / ha - 2012 and 2011, respectively.

The forest site capacity using was quantitatively assessed for the stands of the main forest-forming species of Ukraine, Scots pine and common oak, taking into account natural zones and forest types. The tables of productivity of modal and highly productive pine and oak stands have been developed. It has been found that the stands use an average of 50–75 % of the forest site capacity of lands. The average weighted value of the capacity used by pine forests was 68–76 % in the Polissya zone, 70–78 % and 68–73 % in the Right-bank and Left-bank Forest-Steppe zones respectively, and 54–78 % in the Steppe zone. For oak stands, the value was 71–75 % and 63–71 % for the Right-bank and Left-bank Forest-Steppe zones respectively and 65–75 % for the Steppe zone. The basis for increasing the productivity of forests was confirmed to be the differentiation of forest management systems and individual forestry activities on a zonal and typological basis.

The results of studies on the dynamics of the formation of the area of leaves of plants of beetroot canteen depending on varietal characteristics and sowing time in the conditions of the Forest-Steppe of Right-Bank Ukraine are presented. The dependence of the growth and development of beetroot plants on varietal characteristics and sowing dates, as well as on weather conditions that were in the studied time, was revealed. The largest number of leaves in the phase of intensive root formation was formed by plants with a sowing period of I decade of May: 13.3 pcs. / plant – Bordo Kharkivskiy, 13.1 pcs. / plant – Opolskiy. The greatest mass of the root crop in the phase of intensive root formation was planted at a sowing period of the third decade of April: the Bordo Kharkivskiy – 72.4 g, the variety Opolskiy – 43.5 g. The same pattern was observed when taking into account the mass of the aerial part of beetroot. In the Bordo Kharkivskiy variety, it varied from 92.4 g to 87.5 g depending on the sowing time, in the Opolskiy variety from 33.7 g to 31.7 g, that is, the beet plants of the Bordo Kharkivskiy cultivar formed a significantly larger mass of the aerial part in comparison with the Opolskiy variety. Plants were sown with the largest leaf area at a sowing period of the 3rd decade of April: in the Bordo Kharkivskiy – 1.2 – 4.0 thousand m2 / ha, in the Opolskiy variety – 1.0 – 2.3 thousand m2 / ha. According to the results of the crop accounting, it was found that it depended on the variety and sowing period of beetroot. On average, over the years of research, the highest yield was observed with a sowing period of the third decade of April: 63.1 t / ha for the Bordo Kharkivskiy variety, 55.9 t / ha for the Opolskiy variety.

Increased energy demand end to the world grew by 39% between 1990 to 2008 and further increased by 40% between 2007 to 2030. Energy consumption in buildings has been identified to contribute up to 40% of the total world. Through the selection of methods and the right strategy will reduce the problem of increase energy in buildings. Based on the theory of energy efficiency developed it can achieve through three main factors; a) building design; b) design of services; c) user behavior. This paper aims to discuss methods to benchmark user perception on energy efficiency in school buildings.Keywords: Benchmarking; energy efficiency; school building; user perceptioneISSN 2398-4279 © 2018.
