The study showed that the average seed yield of winter oilseed rape amounted to 3.97 t ha–1. The highest yields of oilseed rape were obtained in Przecław and Skołoszów. Yields obtained in Boguchwała were significantly lower, but only in relation to those obtained in Przecław. The lowest yields of oilseed rape were obtained in Nowy Lubliniec. Oilseed rape plants attained technical ripeness the earliest in Przecław and Nowy Lubliniec, as compared to those grown in Skołoszów and Boguchwała. In the years of the study oilseed rape plants did not suffer from frost bite, the poorest overwintering being noted in Przecław. Infestation with black spot of cruciferous plants was at similar levels in the particular localities. Fat content in the seeds did not depend significantly on the habitat conditions. The highest fat yield per hectare was obtained in Przecław, significantly lower in Skołoszów and Boguchwała, and the lowest in Nowy Lubliniec. Overwintering of oilseed rape plants was the poorest in the season of 2015/2016, but in spite of that the yield of seeds amounted to 4.07 t ha–1. In the analysed years, oilseed rape plants attained their technical ripeness phase on similar dates. In 2015 fat content in seeds was the highest, nut fat yield per hectare was the lowest. In that year, the lowest level of infestation with black spot of coniferous plants was noted. On average, the highest seed yield and fat yield was obtained in 2017.

The study was conducted in the years 2009-2011, on a private farm. The experiment was set up in the split-plot design, in three replicates. Two experimental factors were analysed: A – time of harvest of maize green forage: I – in the stage of tasseling (75% of the plants in that stage of growth), II – in the stage of milky ripeness of the plants (after three weeks), III – in the stage of waxy ripeness of the plants (after three weeks), and B – cultivars with various lengths of the vegetation period: Pyroxenia, Codimi, Moschus, Alombo, Celive. The following parameters were determined in the collected samples of plant material: content of crude ash, digestibility of organic matter, and digestibility of dry matter. The results obtained permit the conclusion that the precipitation and temperature conditions in the years of the study caused a significant differentiation in the feed value of the green forage of the European maize cultivars. The digestibility of organic matter (OM) and the digestibility of dry matter (DM) of maize green forage were the highest if the harvest was performed in the stage of waxy ripeness of the plants in 2010, a year with the highest precipitation total. The objective of the study was to determine the effect of the harvest date, and of the selection of cultivars from the Common catalogue of varieties of agricultural plant species (CCA), cultivated in relation to the precipitation and temperature conditions, on the feed value of green forage of maize plants.

The paper presents a study on the content of selected chemical components in waters of the low moor peatland “Błoto Kraków” and the navigable canal Budzień–Krępa running across the peatland. Samples of water from the peatland and from the canal were collected three times during the vegetation period, in April, August and October. Also soil samples were collected, from the surface horizon of the peatland. The soil samples were characterised by a low degree of degradation of accumulated organic matter, an acidic reaction and a low ash content. The peatland waters were characterised by statistically significantly higher levels of most of the assayed ions and statistically significantly higher mineralisation compared to the canal waters. Also the content of nutrients – nitrate, ammonium and phosphate ions, was statistically significantly higher in the peatland waters. In the case of the content of heavy metals, the peatland waters were characterised by statistically significantly higher levels of iron, manganese and nickel, relative to water sampled from the canal. No statistically significant differences were noted in the content of lead and copper. This may mean that, under conditions of acidic reaction, certain elements are liberated from the sorptive complex of the peatland soils, and migrate to surface waters, causing their contamination.

The dynamic of soil moisture may be studied through water flux, storage, moisture conductivity and movement into the soil pore spaces. The volume of pore space in the soil and also the size, shape, type, continuity and distribution of the pores are important characteristics related to the storage, conductivity and movement of water and gases. The movement of water by gravitational forces in the natural soils occurs principally through the non-capillary pores (i.e. rapidly drained pores), while other movements occur in capillaries which may be classified as coarse and fine capillary pores. The unsaturated condition of soil water is a common state in nature after rainfall or as a result of irrigation, therefore, the purpose of this study was to develop equations to describe and estimate the unsaturated hydraulic conductivity K(θ) in relation to soil pore-size classes that contained the available water in the soil root zone. The equations were based on a water-retention curve, saturated hydraulic conductivity and pore-size function measured from undisturbed cores. The equations were applied to three soil profiles from the Nile Delta and compared with measured K(θ) data from two field experiments, which were conducted in clay in an unsaturated condition and in sandy soil areas using the internal drainage in situ method. The pore size function f(r) represents the fraction of the total pore whichvolume, which was contributed by pores with radii from 0 to ∞ at the prevailing degree of saturation. Data showed the applicability of the suggested equations for calculating unsaturated hydraulic conductivity in the soil pores even for soils with a high proportion of clay.

The experiment had a randomized block design with three replications. The first experimental factor was a number of common onion cultivars: ‘Whitney Wing F1’, ‘Spirit F1’ and ‘Red Baron’. The second experimental factor was the effect of two plant growth biostimulants; Calleaf Aminovital and Maximus Amino Protect, on the yield and quality of the onions. In the control treatment, plots were sprayed with water. The total yield, marketable yield and the marketable yield as a percentage of the total yield, the weight, vertical diameter and horizontal diameter of each onion bulb, the content of dry matter, total sugars, reducing sugars, L-ascorbic acid and nitrates (V) in the onions were determined in the study. The evaluated cultivars differed significantly with regard to the weight and size of the onions. Onions of cv. ‘Whitney Wing F1’ were characterized by a greater yield, and the weight, vertical diameter and horizontal diameter of the bulbs were all higher than they were for the remaining cultivars. The concentrations of dry matter, total sugars, L-ascorbic acid and nitrates (V) were higher in cv. ‘Red Baron’. The contents of L-ascorbic acid and nitrates (V) were significantly affected by the application of biostimulants, and the effects were more pronounced for onions treated with Maximus Amino Protect. The interaction between the experimental factors had a significant effect on the weight of individual onion bulbs, and on the concentrations of dry matter and L-ascorbic acid in the edible plant parts.
