Our studies were aimed at determination of the effects of increasing copper rates (0, 140, 280 and 420 mg Cu kg-1 soil) on yields of oats, spring rape and field bean and on enzymatic activity of the soil. No effects of copper on yields of all studied crops were observed. Copper application resulted in inhibition of soil enzymes activity and in decrease of biochemical index of potential soil fertility for oats, spring rape and field bean. Application of bacterial inoculum or soil amendment with straw diminished copper toxic effects only in low extent.

The aim of the research was evaluation of the effect of agrotechnical level on the brewing quality of winter barley grain with the use of 35-2 (IV) fractional design. Quality parameters of malting barley malt and grain were subjected to analysis. The analysis of experimental features was based on the linear model. In case of rejecting the null hypothesis (H0), multiple comparison test SNK was applied with the significance level P = 0.05. It was proved that quality parameters of winter barley malt are typical cultivar traits, which to a slight degree may be modified with the use of a different level of agricultural techniques. The only agrotechnical factor which significantly affected quality parameters of malt obtained from winter barley grain was nitrogen fertilization. Together with the increase of nitrogen fertilization level, extractivity and Kolbach index significantly deteriorated, while value of diastatic power improved.

The aim of the research was determination of the relationship between agrotechnical factors and the yield of winter malting barley cv. Corbie. Grain yield and its components were discussed. The source of results was field experiment carried out at the Experimental Station „Bałcyny Sp. z o.o.” near Ostróda, under favourable weather conditions for winter barley in the years 2006-2008. 35-2(IV) fractional design was applied in two replications with 27 combinations in each one, in which at the same time 5 factors were tested (A, B, C, D, E) on three levels (0, 1, 2). Very high, though diversified in years, yield of winter barley cv Corbie was confirmed on the soil of the good wheat complex. During studies, the plants of this cultivar overwintered well, to a slight degree they lodged, and their infection with fungal diseases was low. Relationship between the yield and technological level was smaller than assumed in the working hypothesis. The highest grain yield was obtained from barley which was sown earliest (September 9-11th), at a rate of 450 grains·m-2 with spring N fertilization at a rate of 60 kg N·ha-1. These were treatments protected with a dressing and 2 fungicide treatments at the time of growing and treated with regulator Retar 480 SL.

The aim of this study was to precisely quantify the effect of different level and time of nitrogen application on the field and malting quality of spring barley grain of cultivar Prestige. Source of results was the field experiment carried out in 2003-2005. The experiment was carried out with the split-plot method in 4 replications. 8 fertilization combinations were tested (0; 20; 40; 40 (20 + 20); 60; 60 (40 + 20); 80; 80 (60 + 20) kg N·ha⁻¹). It was found that in soil of the good wheat complex at content Nmin. = 55-77 kg·ha⁻¹ in layer 0-90 cm in spring high grain yields are obtained already at fertilization 40-60 kg N·ha⁻¹. Considerably higher productivity of these rates is obtained when they were divided into two parts – presowing and that applied at 23 BBCH stage. Raw material of the malting cultivar (Prestige) collected under different conditions of weather (year with average total precipitation and wet year) and fertilization (N rates from 20 to 80 kg N·ha⁻¹) is characterized by small variability of main qualitative index values of grain, malt and wort and comprehensive Q index according to EBC.
