The purpose of study was determination the energetic expenditure of triticale cultivation at different fertilization technique. There were calculated expenditure of treatments, natural resources, materials, durable means and equivalent of real work. It was showed, that the sum of the total energy expenditure in triticale cultivation was from 16723.2 to 21864.8 MJ ha⁻¹. The lower expenditures were with soil fertilization technique without objects with higher manganese dose (10.0 kg ha⁻¹) and with copper, zinc and manganese applied together at nitrogen dose 80 and 120 kg ha⁻¹ independent with microelement dose. The higher sum of total energy expenditure was with all microelements applied together before triticale sawing (to soil) depend on ferlilization before sawing with copper, zinc or manganese. There was not significant different in the same case with spray application of studied microelements. In the energy expenditure structure of triticale cultivation the higher participation (64.4–71.7%) was shoved with raw and materials, the lower (17.2–21.5% and 8.9–11.4%) with immediate energy carriers and exploitation expenditure and, the lowest (2.2–2.7%) with human work.

The response of radish seedlings (Raphanus sativus L. subvar. radicula Pers.), as non-target plant, to various doses of glyphosate applied to root zone was studied in the experiment. The glyphosate was used at concentrations 0.1, 0.5 and 2.0 mM, and the study was conducted on seedlings grown in hydroponic cultures in controlled light and temperature conditions. In the experiment, roots of seedlings were exposed to glyphosate for 4, 7 or 14 days. In order to evaluate the effect of glyphosate, length and biomass of the seedling organs, as well as contents of anthocyanins in hypocotyls and cotyledons have been measured. Glyphosate applied to root zone had considerably higher impact on the growth of the primary root than shoot of radish seedlings. Short-term exposure to glyphosate led to the stimulation of growth and biomass organs of the radish seedling, but such treatment had no effect on the contents of anthocyanins in the cotyledons and hypocotyl. However, after longer exposure to glyphosate a decrease of anthocyanins content in the hypocotyl and its increase in the cotyledons was noted.

The subject matter of an emergy analysis was the environmental system of a model miscanthus×giganteus cultivation. Assessment of environmental work contribution to the cultivation of renewable biomass was performed based on the energy value theory (EVT) created by Howard T. Odum, which combines the principles of thermodynamics, ecology and economics by means of a single unit of measurement – emergy. The concept of emergy is based on energy transformation ratio between each elements of the ecosystem and emergy is a measure of quality differences between different forms and streams of energy. Flow of energy and materials between the environment and the model cultivation was determined. The analysis of emergy allowed the evaluation of all identified streams that power the analysed system, especially the ones which are omitted by traditional economics due to inability to price or to common availability. EVT, whose principles are based on transformation of primary solar energy that powers all systems within the cycle of life on our planet, opens the real environmental costs for assessment. In order to determine and consider the value of environment in the process of biomass production, a basic study was conducted for a model cultivation of miscanthus within the scope of elemental analysis of collected biomass and soil. An attempt was made at the assessment of environmental contribution into a renewable energy source, that is, biomass. The results showed that the contribution of soil components emergy in the creation of biomass was the most significant. Renewability of the analysed system reached 18%, which proves considerable instability of the system. Eighty two percent of environmental contribution into the formation of renewable biomass was constituted by non-renewable sources which may result in degradation of the local ecosystem over a short period of time. Cultivation requires to be supplied with basic nutrients in order to restore environmental balance. The cost of environmental contribution not considered by humans was circa 314 $ yearˉ¹.

Among liquid biofuels the most practical meaning has the biodiesel production from vegetable oil. The European Union has been introducing regulations that oblige fuel corporations to use admixture of biofuels in petrol and diesel fuel oil. That is why, the demand for the rapeseed oil is dynamically increasing. In order to cope with the market’s challenges, Poland must increase (almost twice) the acreage of the rape sowing similarly to other European countries. The research conducted among rape manufacturers in Western Pomeranian province indicate that the growth of the rape participation in the structure of sowings, and plans for next years assume its expansion to more than 30%.

The effect of term of planting and size of bulbs on the yield of Allium moly bulbs was examined. Bulbs of circumference of 5–6 and 6–7 cm were planted in three terms: 29.09; 09.10 and 19.10. It was stated that term of planting as well as size of bulbs have significant effect on number and weight of bulbs in the total yield and in the yield of the biggest bulbs (over 6 cm circumference). The optimal term of planting was 29.09, when the best results were obtained. Bulbs of circumference of 5–6 cm gave significantly bigger yield than those of 6–7 cm circumference in respect to quantity and weight.

We analysed the essential oils of cultivated material of Thymus xtoletanus Ladero and its parents, Th. mastichina (L.) L. and Th. villosus subsp. lusitanicus (Boiss.) Coutinho, with seeds from the same locality in the centre of the Iberian Peninsula. The essential oil of Th. xtoletanus, which had not been analyzed previously, presented 1,8-cineole as the major component (25.5%), as was also the case for Th. mastichina (76.1%). Other components with a major presence in Th. xtoletanus and Th. villosus subsp. lusitanicus were [(Z)-β-ocimene (8.1%); camphor (4.5%); sabinene (3.2%); α-pinene (2.8%)], and [(Z)-β-ocimene (4.1%), camphor (9.8%), sabinene (2.8%), α-pinene (7.1%)], respectively. However, in the hybrid the components β-phelandrene (14.5%), limonene (6.9%), (E)-γ-bisabolene (3.5%), and viridiflorol (3.3%) stood out, inter alia, whereas their presence in the parents was limited. The study confirms the hybrid origin of Th. xtoletanus as intermediate between Th. mastichina and Th. villosus subsp. lusitanicus.

Civilizational development requires seeking for more and more modern methods of satisfying growing needs of the society. Living standards grow together with economic growth and, as a result, demand for energy grows as well. This fact is tantamount with the necessity to look for alternative energy sources. Otherwise, our civilization will soon have to face degradation of natural environment and shortage of conventional energy resources. Under Polish conditions, crucial role in utilizing renewable energy is played by biomass, and its importance is going to grow over the years. The present study has assessed productivity of three willow clones: Tur, Ekotur and Turbo, grown in short rotations on farmland.

The aim of this 3-year study was to determine the influence of harvest time on dry matter, total dietary fibre, fractional composition of dietary fibre (acid detergent fibre (ADF) and neutral detergent fibre (NDF)), water-soluble carbohydrates (WSCs) and inulin content in tubers of different cultivars of Jerusalem artichoke (Helianthus tuberosus L.): ‘Rubik’, ‘Albik’ and ‘Sauliai’. The tubers were harvested in spring (March and April) and autumn (October and November). Our study shows that the largest amount of WSC to exist in ‘Rubik’ tubers harvested especially during October. In contrast, the largest amount of total dietary fibres and their fractions (NDF and ADF) accumulated in ‘Albik’ tubers during the spring harvest month (April). The largest amount of inulin was obtained from ‘Sauliai’ tubers harvested in October. Based on our results, it is advisable to use the ‘Sauliai’ tubers from the harvest time during October to obtain the largest amount of inulin.

The study was conducted from 2013 to 2015 on 10–13-year-old apple trees cv. ‘Szampion’ (M.9. rootstock) in experimental orchard of Department of Pomology, University of Life Sciences in Lublin. On the trees intensively flowering in 2013, the thinning treatments were performed as follows: thinning at the pink bud stage to the 50% of flower clusters leaving only a king flower in the remaining flower clusters; thinning at the pink bud stage to the 50% of flower clusters leaving only one lateral flower in the remaining flower clusters, thinning 4 weeks after full bloom to the 50% of fruit clusters leaving only a fruit from king flower in the remaining fruit clusters, thinning 4 weeks after full bloom to the 50% of fruit clusters leaving only one fruit from lateral flower in the remaining fruit clusters. Intensively flowering control trees in 2013 and poorly flowering trees in 2013 were left unthinned. The best results in terms of regularity of yielding and high-quality fruits after thinning at pink bud stage to king flower, were obtained. The largest fluctuations in yields were observed with the control tree that flowered poorly in the beginning of the study. It was found that the cultivar ‘Szampion’ is characterized by equal distribution of fruits in lower and middle parts of crown, however in the top of crown, the amount of fruits is significantly lower. Apples with the largest mean fruit weight were from spurs on wood older than two years. However the best flesh firmness, soluble solids and dry matter content was detected in fruits from brindles.

Essential nutritional components are quantified in the study in addition to major antioxidants, carotenoids, phenols and flavonoids. Their antioxidant activities were also analyzed using DPPH, ABTS and hydrogen peroxide radical scavenging activities and by determining their iron reducing power. Results indicated that the highest quantity of nutritional and antioxidant components was obtained in red variety (4.63 mg/g ascorbic acid, 10.32 mg/g total carotenoid content, 61.50 mg/g total flavonoid content, 310.27 mg/g total phenolic content) followed by orange, yellow and green varieties. Similar trend was observed while analyzing their antioxidant activities by different methods. In studying correlation between components and antioxidant activity, a strong correlation was obtained for ABTS radical scavenging activity with total phenolic content (R2 = 0.722) and total carotenoid contents (R2 = 0.709), while moderate correlation was observed for ABTS radical scavenging activity with total flavonoid contents (R2 = 0.517) and ascorbic acid (R2 = 0.673).
