    The aim of the study carried out on the basis of a field experiment was to compare results obtained during cultivation of winter triticale in the organic and conventional farming systems. Comparing these two systems (organic with conventional), changes in the content of macroelements (phosphorus, potassium, calcium, magnesium), and microelements (manganese, iron, zinc and copper) were analyzed in the triticale grain. The study involved four triticale varieties: Benetto, Cultivo, Grenado, and Moderato. The field experiment was performed in 2010–2011 at The National Research Institute for Fisheries Affairs Mecklenburg – Vorpommern in Gulzow, Germany. Grain of all triticale varieties grown in an organic systems contained more phosphorus and magnesium. Compared tillage systems did not differentiate calcium and potassium in grain of triticale Benetto, Cultivo, Grenado, and Moderato varieties. No relationship was found between the total content of phosphorus, calcium and magnesium vs. cultivars. The total potassium content in triticale grain was differentiated by the varietal factor. The triticale grain of all tested varieties (Benetto, Cultivo, Grenado, and Moderato) grown in organic system was characterized by higher – by ten or so per cents – iron, zinc, manganese, and copper contents as compared to the conventional systems.

    Glycoalkaloid content in the tubers of potato manured with undersown catch crops in the integrated and organic production system
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Makarewicz, Artur; Płaza, Anna; Gąsiorowska, Barbara; Opatowicz, Natalia; Department of Agrotechnology, University of Natural Sciences and Humanities in Siedlce,; Department of Agrotechnology, University of Natural Sciences and Humanities in Siedlce,; Department of Agrotechnology, University of Natural Sciences and Humanities in Siedlce,; Department of Agronomy, West Pomeranian University of Technology, Szczecin
    The paper presents results of studies carried out in 2006-2009 to determine the effect of the biomass of undersown catch crops, which were either autumn-incorporated or left on the soil surface as mulch for spring incorporation, on glycoalkaloid content in the tubers of potato grown in the integrated and organic production system. An experiment was conducted to examine the following two factors: 1. manuring with undersown catch crops: control (no undersown catch crop), farmyard manure, white melilot, white melilot + westerwolds ryegrass, westerwolds ryegrass, white melilot – mulch, white melilot + westerwolds ryegrass – mulch, westerwolds ryegrass – mulch; 2. production system: integrated and organic. Glycoalkaloid content was determined in potato tubers by means of the Bergers method. The lowest glycoalkaloid content was determined in potato tubers manured with white melilot and a mixture of white melilot and westerwolds ryegrass, either autumn- or spring-incorporated, as well as westerwolds ryegrass left on the soil surface as mulch for spring incorporation. Potato tubers grown in the integrated production system contained less glycoalkaloids compared with organic potato.

    Preliminary estimation the impact of effective microorganisms and fertilization on the yield, photosynthetic activity, water use efficiency of japanese knotweed (Polygonum Cuspidatum Siebold & Zucc.) and contents of selected minerals in soil

    The aim of research was preliminary assessment the influence of effective microorganisms and fertilization manure on the yield, morphological traits, photosynthetic activity, water use efficiency of Japanese knotweed (Polygonum Cuspidatum Siebold & Zucc.) and on amount of selected minerals in soil. Field experiment was conducted in 2014 and 2015 in Experimental Station in Lipnik near Stargard Szczeciński (53o12’N; 14o27’E), Poland. Experimental factors were EM – effective microorganisms (preparation) and fertilization manure. The experiment was conducted in the totally random system. The experiment consisted of four objects, in four replication: 1 – control (without EM preparation and fertilization); 2 – EM preparation; 3 – fertilization granulated manure; 4 – EM preparation and fertilization granulated manure. Effective microorganisms and manure fertilization had no significant effect on the yield, the number of plants per plot, their height, and diameter of stems of Japanese knotweed. Plants fertilized with manure and EM preparation with manure had higher concentrations of studied macronutrients (magnesium, calcium, phosphorus) and microelements. Greater intensity of assimilation and transpiration was observed in plants grown in the control plots (without EM and manure). Plant grown on objects fertilized with manure as well as EM preparation and manure- -treated better utilized water during its shortages (in 2015 year).
