We studied the influence of complex application of inoculation and retardant on the formation of photosynthetic and seed productivity of white lupine (Lupinus albus L.) plants seed varieties. The field research was conducted on the basis of the research farm “Agronomichne” of Vinnytsia National Agrarian University, village Agronomichne, Vinnytsa district, Vinnytsia region, Ukraine. Features of the growth and development of white lupine (Lupinus albus L.) plants are examined. There has been established a positive effect of the combination of inoculation with the bacterial agent and growth stimulator on the productivity of white lupine, which is important for the formation of high and stable yields. The papers presents the results of studies on the effect of pre-sowing seed treatment and foliar nutrion under conditions of the right-bank Forest-Steppe of Ukraine on the photosynthetic apparatus of white lupine plants. It has been established that bacterial agents and growth stimulators increase white lupine seed productivity due to optimization of the studied technological methods of cultivation. The optimal leaf surface area that provided maximum grain yield has been determined. The research has established a positive effect of pre-sowing seed treatment with the bacterial agent Rhizohumin and the growth stimulator Emistym C and foliar nutrition with Emistym C on the contents of chlorophyll a + b, observed the maximum yield of the white lupine leaves. The influence of the investigated technological methods on the formation of the photosynthetic and chlorophyll synthesis in the leaves of white lupine has been proved. The preparations studied induce intensive development of the photosynthetic apparatus, yield increase, improvement of the yield structure and they improve grain quality under conditions of right-bank Forest-Steppe of Ukraine. The issue of seed bacterization and application of growth stimulators requires a more detailed study. Theefore, such researches are relevant and significance in terms of both practical and scientific value.
The paper estimates the possibility of obtaining solid biomass for energy purposes in the Biała Podlaska County (Lublin Voivodeship, Poland). The estimates were based on data on: forest area, orchards and tree stands, land use, crop structure, animal population, and marginal land area in the County. It was found that in most communes, there are great possibilities of obtaining biomass for energy purposes. The largest resource is straw (243,501 Mg per year), which should first be used in agriculture as animal litter and organic fertilizer. Only its surplus can be intended for the combustion and production of pellets and briquettes. In the County, large areas of poor quality land were inventoried, on which perennial energy plants with low requirements can be grown. Up to 113,595 Mg of biomass can be obtained there. The basic condition for the development of targeted energy crops is the emergence of a biomass market: installations that convert biomass into fuels or produce energy on a local scale and sell it to power plants. Currently, a commonly used resource is wood biomass from forests and wood processing, which is used as fuel in domestic boilers, as well as for the production of pellets and briquettes.
By analyzing the resources of the economic infrastructure (distilleries, diaries, fruit and vegetable processing and meat processing factories) of the Biała Podlaska County, the possibilities of the biomass obtaining and creating the biogas plants basing on the agri-food industry waste were estimated. The stocking of animals was the basis for the assessment of manure and slurry resources that can be subjected to the methane fermentation process. On the basis of the data concerning the surface of the wastelands, located on the Biała Podlaska County territory, the possibilities of the biomass from special crops were specified. In the Biała Podlaska County, it was established that there are possibilities for obtaining the biomass for the biogas production: from livestock production (1 475 272 GJ/year), maize cropping in marginal lands (172 875 GJ/year) and wastes and by-products from food industry (51 081 GJ/year). The estimated potential of biogas allows for the construction of several agricultural biogas plants with a capacity of 1 MW e each, often built in Poland. The usage of the identified resources enabling the improvement of the energetic safety and also can contribute to the sustainable development of rural areas and agriculture.
The work aimed to create and share for public use an Interactive Map of the Main Bus Station in Lublin, using the base map as a primary data source. This solution may be an alternative to the most popular way of basing on the Google Maps or OpenStreetMap data. The final visualization was prepared by connecting digital geospatial data processing methods with land surveying techniques. The map was designed as an information system for travellers and other people moving through the bus station facility. The intended 'interactivity' includes the ability to display proper information about selected objects and choosing preferred viewing parameters, such as the scale or the type of base layer. The final product is an Internet application, created and published using the ArcGIS Online service, in contrast with the majority of similar applications, which are typically developed using Google Maps tools.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
