The present study was conducted at the Felin Experi- mental Farm, belonging to the University of Life Sciences in Lublin, during the period 2005–2008. The experimental material consisted of maiden trees of sour cherry 'Łutówka' budded on seedlings of mahaleb cherry (<em>Prunus mahaleb </em>L.) of unknown origin. The experiment evaluated the effect of four budding times: 15 July, 1 August, 15 August, and 1 September, on the quality of cherry trees in a nursery. The mean for the three years showed that budding time did not have a significant effect on the quality of cherry trees in the nursery. It was observed that the budding of mahaleb cherry performed on the two August dates (1st and 15th) had a more beneficial effect on the growth and branching of trees than the budding done on 15 July and 1 September. The quality of maiden cherry trees 'Łutówka' in the nursery was primarily dependent on weather conditions in a given growing season, which is evidenced by the significant differences between production cycles, high variation in the quantitative results in individual years, and the absence of significant differences in the mean for 2006–2008.

Abstract. The Optical Spectrograph and InfraRed Imaging System (OSIRIS) on the Odin satellite is currently in its 12th year of observing the Earth's limb. For the first time, continuous temperature profiles extending from the stratopause to the upper mesosphere have been derived from OSIRIS measurements of Rayleigh-scattered sunlight. Through most of the mesosphere, OSIRIS temperatures are in good agreement with coincident temperature profiles derived from other satellite and ground-based measurements. In the altitude region of 55–80 km, OSIRIS temperatures are typically within 4–5 K of those from the SABER, ACE-FTS, and SOFIE instruments on the TIMED, SciSat-I, and AIM satellites, respectively. The mean differences between individual OSIRIS profiles and those of the other satellite instruments are typically within the combined uncertainties and previously reported biases. OSIRIS temperatures are typically within 2 K of those from the University of Western Ontario's Purple Crow Lidar in the altitude region of 52–79 km, where the mean differences are within combined uncertainties. Near 84 km, OSIRIS temperatures exhibit a cold bias of 10–15 K, which is due to a cold bias in OSIRIS O2 A-band temperatures at 85 km, the upper boundary of the Rayleigh-scatter derived temperatures; and near 48 km OSIRIS temperatures exhibit a cold bias of 5–15 K, which is likely due to multiple-scatter effects that are not taken into account in the retrieval.

Seed yield and overwintering of seeds of 22 Australian subterranean clover varieties were investigated in 1986 and 1987 at the Viikki Experimental Farm of the University of Helsinki. The seed yield varied remarkbly according to the variety and weather conditions of the two summers. Some varieties, such as Seaton Park, Woogenellup and Karridale, and during the summer of 1987 also the early variety Dalkeith, produced lots of seed. Some late varieties, e.g. Treeton, Tallarook and Esperance, produced very few seeds or no seeds at all. A considerable proportion of the seeds degenerated during the wet autumn conditions, by the end of October. Many seeds showed embryo dormancy, but complete dormancy or hard seeds were found only exeptionally. In spring 1988, some seedlings which had developed from overwintered burrs were found. There seems to be little hope of finding self-seeding subterranean clovers suitable for Finnish growing conditions.

The objective of this field crop study was to compare the effect of organic (cattle manure, off-season cover crop) and mineral N (NH4NO3; 0, 50, 100° 150 kg N ha−1) fertilizers on (i) gluten-starch interaction, and (ii) rheological properties of winter wheat dough. Data were collected from the long-term field experiment located in the Baltic Sea region (58°22’ N, 26°40’ E) in years 2013–2017. The amount of minuppueral N 150 kg ha–1 applied in two parts before flowering ensured higher gluten content (31 ± 3.3%) and dough quality (81 ± 7.4 mm) due to more positive interactions between gluten proteins and starch granules. The quality of dough was more variable in organic treatments (ranged up to 33%) because the availability of organic N was more variable and sensitivity to the weather conditions was higher. The mean variability of different dough properties over trial years under organic treatments was 1.4–2.0 times higher than in the treatment with 150 kg N ha−1.

This work aimed to evaluate the technical feasibility of lettuce, Indian spinach and taro intercropping under organic fertilizer. The experiment was performed at Água Limpa Farm, belonging to the University of Brasília, located in Brasília - DF, from October 2014 to June 2015. A completely randomized block design with seven treatments and four replications was used. Each experimental plot had 18 m2 (4.5 m x 4.0 m), totaling 28 plots. The following treatments were assessed: lettuce monoculture, Indian spinach monoculture, taro monoculture, lettuce/Indian spinach intercropping, lettuce/taro intercropping, Indian spinach/taro intercropping, and lettuce/Indian spinach/taro intercropping. In all treatments, the following spacings were used: 0.25 x 0.25 m (lettuce), 1.0 x 0.6 m (Indian spinach), and 1.0 x 0.3 m (taro). Crop production was evaluated from sample plants taken from the central part of each plot. Two harvests of lettuce, two of Indian spinach and one of taro were carried out during intercropping.  In the first cycle, lettuce highest mean yield values were observed in the lettuce monoculture (3.5 kg m-2) and lettuce/Indian spinach intercropping (3.4 kg m-2). The crop reached the commercial size in both production cycles, except when intercropped with Indian spinach in the second cycle. The highest Indian spinach mean fresh mass was recorded in the lettuce/Indian spinach intercropping (974.7 g plant-1; first harvest) and monoculture (327.5 g plant-1; second harvest). The yield of taro rhizomes was significantly higher when intercropped with lettuce, showing a mean value of 16.8 kg m-2. The intercropping arrangements with lettuce increased yield of nonconventional vegetables. The conventional and nonconventional vegetables’ intercropping technique increased species diversity in the area without interfering in the agronomic performance and quality of the crops.

AbstractWeather conditions prevailing in Poland often cause that meadow sward designated for silage is harvested too late, which decreases the quality of prepared silage. The aim of the research was to assess the quality of silages from dried meadow sward. The silages were ensiled in large cylindrical bales in selected individual farms specializing in milk production. The farms where the research was carried out were located in three voivodeships: slaskie, malopolskie and podkarpackie. In the prepared plant material, the basic chemical composition was determined using the method. When comparing the mean values, it was established that silages from the investigated region had a favourable content of total protein, the highest concentration was recorded for silages from Slask, followed by Malopolska and Podkarpacie. A slightly elevated concentration of crude fibre, fraction of acid detergent fibre (ADF) and neutral detergent fibre (NDF), was recorded. This fact shows that farmers collect raw material, particularly from the first cut, too late. Nutrient value of silages from meadow sward decreases with progressing vegetation. Higher protein and energy losses during sward ensiling were also observed at considerable drying of the plant material. In most cases, silages from the studied farms had a low content of monosaccharides. The carried out chemical analyses showed that in overall assessment the studied silages are of good quality; silages prepared from meadow sward from the third cut had the highest value. Proper technology of preservation of meadow sward is one of important factors in the production of feed for ruminants.

Over the period 2006–2009 in Lublin, a study was conducted to determine the effect of five types of rootstock: ‘Colt’, ‘F12/1’, sweet cherry (<em>Prunus avium </em>L.), ‘GiSelA 5’ and ‘Piast’ mahaleb cherry (<em>Prunus mahaleb </em>L.), on the growth and quality of maiden sweet cherry trees cv. ‘Regina’ in a commercial nursery. Based on the three-year average, rootstocks were shown to have a significant effect on the investigated quality characteristics of maiden sweet cherry trees. Trees budded on ‘Colt’ vegetative rootstock were characterized by strongest growth and best quality. In each year, they were thicker, higher and better branched than sweet cherries on the rootstock. Under the tested conditions, ‘GiSelA 5’ dwarf rootstock significantly reduced the growth and quality of budded sweet cherry trees in the nursery. During the period 2007–2009, no physiological incompatibility symptoms were observed ‘Regina’ sweet cherry cv. and ‘Piast’ seedling rootstocks. The growth of trees budded on ‘Piast’ mahaleb cherry was poorer than on ‘Colt’ clonal rootstock, but it was stronger than on ‘F12/1’ and <em>Prunus avium</em> L. rootstocks.

Abstract Fruit set is a crucial stage in the process of yield formation, which is influenced by environmental factors, growing technologies and peculiarities of genotype. The aim of the study was to evaluate the quality of pollen (viability and germination capacity) and the effect of weather before and during flowering on fruit set in sour cherry cultivars ‘Latvijas Zemais’, ‘Zentenes’, ‘Bulatnikovskaya’, and ‘Orlica’. The research was carried out in Institute of Horticulture (Latvia University of Agriculture) in 2009-2016. Good pollen viability and germination was found for cultivars ‘Latvijas Zemais’ and ‘Bulatnikovskaya’. Negative effects of increasing air temperature (in the range of 7.7 to 17.5 °C) and relative humidity (in the range of 51.4 to 88.5%) was observed for all cultivars during flowering. The effects of diurnal temperature fluctuations, wind and the amount of days with precipitation differed depending on sour cherry cultivar.

SummaryPremature ejaculation (PE) is the most common sexual dysfunction in men, yet it is not well studied. Its frequency reaches 30% for men from 18 to 59 years of age in different countries. The aim of this article was to investigate the quality of sexual life in men with primary PE operated on with microsurgical penile denervation, using the Brief Male Sexual Functional Inventory (BMSFI). From September 2011 to March 2014, 22 patients were operated on with microsurgical penile denervation in the urology clinic of the University Hospital - Pleven and the Department of Urology at UMHAT Ruse AD. The mean result from the BMSFI in patients was 22 points preoperatively, indicating significant worsening of sexual function and quality of life in all five questionnaire domains. After surgery, the results increased to 28, 33 and 39 respectively, at 3, 6 and 12 months, respectively. Premature ejaculation not only leads to problems in controlling ejaculation but also worsens the overall sexual function and quality of life of patients.

The article presents the methodology for calculating the optimal insulation thickness that is related to the quality of energy supply and fuel prices. Assuming that the total cost following renovation is the sum of the costs of heating and thermal upgrading, it was shown that when calculating the optimal insulation thickness, the thermal resistance of the outer walls should be taken into account. Such calculations, in addition to the characteristics of the heat source, should be carried out taking into account local weather conditions. The study presents the results of such calculations for the building heated with gas and the air-source heat pump. The results of the investigations are referred to the mean climatic conditions recorded in the last 10 years. It was found that for thermal upgrading with the use of foamed polystyrene having the optimum thickness, total investment costs are almost the same, regardless of polystyrene thermal properties. The same also refers to energy costs. The article also provides sample calculations for plaster, the main ingredient of which is perlite. In the case of internal thermal upgrading of the historic buildings, such isolation is recommended in order to prevent moisture problems inside the envelope.

Earliness is also very important in addition to yield and fruit quality for more profitable production in sweet cherry cultivation. Therefore, some preparats are applied to get flowering even earlier in Kemalpaşa District of Izmir province, where sweet cherry fruits from Turkey are harvested the earliest. In this study, it was aimed to determine the effects of different treatments in the pre-flowering period on flowering and fruit quality of sweet cherry fruits. The study was carried out in the 2018 production year in a sweet cherry orchard established with the "0900 Ziraat" (Prunus avium L.) variety grafted on the "idris" (Prunus mahaleb) rootstock belonging to a producer in Kemalpaşa district of Izmir province. Approximately 30 days before flowering, Bud Feed 20 (BF20), 40 (BF40) and 60 mL L-1 (BF60) doses with Sett (3 mL L-1), Erger (50 mL L-1) + CaNO3 were treated to the sweet cherry trees from the leaf. The trees that are sprayed only with water were considered as control. Branches of similar size were selected from 4 different directions of the trees to determine flowering in sweet cherry trees, and the number of flowers bloomed on the branches recorded for 2-day intervals from March 17, when the first flowering was observed until the flowering was completed. The sweet cherry trees treated with BF40 + Sett, BF60 + Sett, and Erger + CaNO3 had the flowering 6-7 days and full bloom 7-8 days before compared to the control trees. The last flowering time of BF60 + Sett treated sweet cherry trees was 8 days earlier than the control trees, and 6 days earlier than the other treatments. It was determined that the weight and diameter of the fruits in  BF60 + Sett and Erger + CaNO3 treated sweet cherry trees were partially higher than the control, while the other quality parameters were similar. The results showed that BF60 + Sett, Erger + CaNO3 and BF40 + Sett treatments were effective in the early flowering of sweet cherry fruits.
