Field studies were carried out in the Didactic and Experimental Farm in Swadzim near Poznań in the years 2004-2007. The objective of the studies was the investigation of the reaction of two types of maize cultivars to zero mineral fertilization and in consequence to the energetic value of the maize raw material grown on CCM in comparison with mineral fertilization. In the experimental studies, a more...
Pot experiment was carried out in the Department of Agronomy, University of Life Sciences in Poznań. Two maize fertilization methods were analyzed; without mineral fertilization and with the use of NPK fertilization. Furthermore, in the NPK fertilization, was applied together with kieserite which is permitted to be used in ecological agriculture. The effect of this method on the development of the...
During the adaptation process of the weights vector that occurs in the iterative presentation of the teaching vector, the MLP type artificial neural network (Multi Layer Perception) attempts to learn the structure of the data. Such a network can learn to recognize aggregates of input data occurring in the input data set regardless of the assumed criteria of similarity and the quantity of the data...
The subject of the study was to develop a neural model for identification of mechanical damage to grain caryopses based on digital photographs. The authors has selected a set of universal features that distinguish damaged and healthy caryopses. As a result of this study it has been performed an artificial neural network of a multilayer perceptron type whose identification capacity is near of the human'...
The paper presents the comparison of biogas and biomethane production efficiency from maize silage (as typical biogas plant substrate) and maize straw silage in order to estimate the possibilities of maize straw application for biogas production. The experiment of biogas production was conducted in the 21-chamber biofermentor at the Institute of Agricultural Engineering. The results show that methane...
The aim of the study was to evaluate the level of weed infestation of maize cultivated in organic farming depending on natural fertilization (20 and 40 t of composted manure per 1 ha) and cultivation method: A - control object (without weed control), B - brush weeder (three times during the vegetation season), C - weeding hoe (three times during the season), D - brush weeder (two times during the...
The studies were conducted in the years 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 reaction of two cultivars of sorghum (GK Aron mid-early and late Sucrosorgo 506) the intercrop with corn, compared to pure sorghum seed was evaluated. Corn was represented by a variety of medium-late, with...
The study focused on toxicity evaluation of selected complexing organic compounds (EDTA, rhamnolipids, quaternary pyridylketoximes and pyridineamidoximes) to monocot plant - maize (Zea mays L.) in aquatic and soil systems. Tests evaluating the seed germination and growth inhibition of shoot and root of maize were carried out at different compound concentrations (ranging from 0 to 1000 mg/kg of dry...
The study focused an assessing the influence of xenobiotics, such as NaCl and diesel oil on germination and early development of maize (Zea mays L.). Through the test the seed germination and growth inhibition of shoot and root of maize were evaluated. The experiments were carried out at different xenobiotics concentration and their mix. It was observed that the presence solely of compounds did not...
Studies on the response of maize to use PRP fertilizer was carried out in 2012-2015 in the Department of Agronomy at the University of Life Sciences in Poznan, in the fields of the Experimental Station Gorzyń in Złotniki. Replacement of the traditional maize fertilization with phosphorus and potassium by PRP technology, both full (PRP SOL with PRP EBV) and the PRP SOL led to a significant increase...
A field experiment was conducted in 2012 to 2013 to determine the effect of tillage, including deep strip tillage, shallow strip tillage and conventional tillage, and weed control method (untreated control, mechanical, chemical) on growth and yield of maize planted after winter rye cover crop. Strip tillage was executed with the use of a universal active tool for the strip tillage and mechanical inter-row...
The aim of the study was to evaluate the weed infestation of maize grown in mixed sowing with other plant species (sunflower, common bean, vetch). The field experiment was carried out in the years 2014-2016 at the ecological farm in Chwałowice, belonging to the Advisory Agricultural Center in Radom, using the randomized block method, in 4 replications, on the soil of the good wheat complex, class...
Between 2005 and 2008 in Swadzim, on the fields of the Experimental and Didactic Station Gorzyń, a department of Poznań University of Life Sciences, the two one factor trials have been carried out on two soil complexes: rye and good wheat ones. The purpose of the study was to determine changes of selected chemical properties of soils under the influence of the use of natural fertilizers, straw or...
In the years 2005-2008, the trials were established on two soils, rye and wheat complexes in Swadzim, in the fields of the Experimental and Didactic Station Gorzyń, of the Poznań University of Life Sciences. The purpose of the study was to determine changes in selected physical properties of soils under the influence of natural fertilizers, straw or winter intercrop under maize grown for silage in...
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...
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...
A field experiment was conducted in 2012 to 2013 to determine the effect of tillage, including deep strip tillage, shallow strip tillage and conventional tillage, and weed control method (untreated control, mechanical, chemical) on weed infestation of maize planted after winter cover crop being intended for silage. Strip tillage was executed with the use of a universal active tool for the strip tillage...
The field experiment was conducted in the years 2014-2016 at AES Grabów (Mazowieckie Voivodeship), belonging to Institute of Soil Science and Plant Cultivation – State Research Institute in Puławy, (Poland) and in ecological farm in Chwałowice (Poland) in the years of 2014-2015.
