In the experimental trial the influence of the aqueous extracts on the germination capacity and surface contamination of the seeds of Brassica oleracea L. white cabbage, ‘Stonehead’ variety was assessed. The extracts in the form of macerate, infusion and decoction were prepared with the use of different morphological parts of 40 plants species. The results obtained allowed to indicate the plants the...
Only products containing substances listed in the Regulations (EC) No 889/2008 and 354/2014 can be used in the protection of organic crops. Despite the common list of active substances and schemes of qualifying products for use in organic farming, availability of measures to protect organic farming in the Member States vary widely. The paper presents data collected in 2017. Obtaining information concerning...
Intensification of agriculture is one of the threats to the environment. Large amounts of applied mineral fertilizers and chemical plant protection products cause soil pollution, as well as pollution of surface and ground waters. Some of the harmful substances get into the human digestive tract through plants and animals. Therefore, more and more people introduce organic food into the menu in the...
The aim of the study was to evaluate the impact of bacterial preparation, containing strains of Lactobacillus genera that stimulate the synthesis of 1,2-propanediol and carboxylic acids of low molecular weight, on aerobic stability of meadow sward silages and biogas yield by means of heterofermentation. Lactobacillus buchneri, L. diolivorans and L. reuteri, which are synergistically active in the...
The paper presents the results of the research on the effect of PRP SOL fertilization on the basic chemical properties of soil and composition of soil solution. The soil has been sampled from the level of humus of many years' experiment established on light soil using traditional fertilization (NPK) and PRP SOL fertilizer was used instead of PK fertilization. Nitrogen doses remained the same in both...
The studies were conducted in 2010-2012, at the Agricultural Experimental Station in Swadzim (52°26′20″N, 16°44′58″E), belonging to the Poznań University of Life Sciences, Poland. The response to sorghum intercropping of two maize varieties: Absolut (medium-early FAO 250) and medium-late Vitras (FAO 270) was evaluated, with reference to pure sowing as a control. Sorghum was represented by the medium-late...
Sugar beet seeds var. Melodia were primed on germination using three different methods: 24 h in water, 21+3 h in water (seeds were dried between 2 cycles) and 24 h in solution of UG MAX - commercially used bacterial treatment. Control combination were non-treated sugar beet seeds. Germination ability, speed and uniformity were examined in different water content in germination medium: 15%, 25% and...
The aim of the study was to assess the influence of organic and natural fertilisation under maize plantation grown in monoculture on the number of selected groups of microorganisms. The experiment was conducted between 2005 and 2007 in plots of the Experimental and Educational Station in Swadzim, Department of Agronomy, Poznań University of Life Sciences, Poland. Soil taken from maize for silage was...
It is possible to obtain much wholesome bulk fodder that meets the requirements of highly productive animals from permanent grasslands of appropriate species composition. Important components of such fodder are: neutral detergent fibres (NDF) and acid detergent fibres (ADF). Based on their content one may calculate digestibility of dry mass (DDM), dry mass intake (DMI) and relative feed value (RFV)...
The addition of straw to chicken manure can influences on humidity, ammonia emission and concentration of phosphorus of the obtaining mixture. This material can be used as a raw material to production of fertilizer pellet or energetic pellet. Because hardness is the most important feature of granulate, research related to the hardness of pellet made from a mixture of chicken manure and rye straw were...
The aim of the study was to evaluate the diversity of invertebrate groups in spring wheat cultivated in different crop production systems. The field experiment was established in 1994 in experimental plot at Agricultural Experimental Station of IUNG-PIB Kępa in Osiny. The research was conducted in 2014-2016 on spring wheat fields in organic, conventional and integrated systems. At designated points...
The aim of the study was to evaluate the degree of weed infestation of spring and winter triticale harvested at different dates, depending on the method of cultivation (with or without undersown crop) in the organic farming system. The research was conducted in the Agricultural Advisory Center in Szepietowo, Poland, in the years of 2014-2016. The experiment took into account the method of cultivation...
Domestic sewage from unsewered scattered areas presents high environmental risk. Due to the high cost of transporting sewage to the municipal sewage treatment plants, the households try to solve the problem in another way, which is very often dangerous to the nature. Polish legislation authorizes the use of domestic sewage as an organic fertilizer in agriculture, once the proper parameters, mainly...
The purpose of this paper is to produce original software for calculating the GLCM matrix and its properties. Application mechanics is based on two AForge.Net library for image segmentation, and the Accord.Net library for calculating the GLCM matrix. The application mechanics have included the ability to calculate the GLCM matrix at the given accounts. The application is equipped with functions that...
A specific objective of this paper was to evaluate a quality of the fruit of individual cultivars Rubus taking into account their usefulness to organic farming. The berry fruits belong to different botanical groups. Type of the fruits is common feature of those fruits. To this fruit group belongo: raspberry (Rubus idaeus), tayberry (Rubus fruticosus x Rubus idaeus), black raspberry (Rubus occidentalis...
Contamination of cereal grains by mold is a serious threat to human and animal health and leads to economic losses. The antagonistic activity of yeast strains isolated from varied habitats against mold was assessed. Based on the in vitro experiments, three strains of yeasts, showing the antagonistic activity towards the growth of 13 mold species isolated from cereals, have been selected. The ability...
The subject of the study refers to the effect of housing and milking systems on yield, chemical composition, and cytological quality of milk from primiparous cows held in two barns belonging to the same owner where cows were fed using the same feed. Cows from barn C were kept in deep litter and milked in a fishbone milking parlour, whereas cows from barn M were kept in box stalls with litter bedding...
Most of products of petroleum have a toxic effects to plants, animals and also to man. Overworked motor oils and mixtures of different petroleum substances are especially dangerous for environment. The aim of this work was to determine the effect of overworked motor oil, diesel and their mixtures on the growth and advancement of chosen species of plants. The effect of increasing concentration of the...
The availability of organic fruit juices on the European market is increasing. There is also a growing range of combinations of various fruit species, as well as fruit juice supplements, such as e.g. herbal infusions, which not only enrich the juices in new flavors, but also can significantly increase their health benefits. Consumers are increasingly looking for natural, organic, high-quality products,...
The development of modern technologies allows for more efficient use of the production potential of farm holdings. Keeping plant production with conventional methods provides a wide range of opportunities for fighting diseases, pests and weeds. Price competitiveness of organic farming due to constraints is greatly hampered. By implementing the elements of precision farming in the production process...
