Opis:
Soil from a field experiment was analyzed to determine: (1) earthworm (Lumbricus) number, (2) organic carbon content, (3) total nitrogen content, (4) available phosphorus content, (5) potassium content, and (6) magnesium content, depending on tillage systems and previous crops cultivated. A two-factor experiment was established in the system of randomized subblocks. Tillage systems (TS): conventional tillage (CT), reduced tillage (RT), and no-tillage (NT), were the main experimental factor; previous crops (CP): winter wheat, winter durum wheat, winter barley, and common pea, were the second-order experimental factor. Shallow ploughing and pre-sowing ploughing were performed in the CT system, double cultivation in the RT system, and only glyphosate treatment in the NT system. An over 2-fold higher number of earthworms per m2 was recorded on RT and NT plots than on CT plots, as well as on plots after winter barley and pea than on plots after winter wheat and winter durum wheat. The contents of organic C and total N were higher in the NT and RT systems compared to the CT system, and also on plots after pea than on plots after all the other analyzed crops. The content of P was higher in the soil from the RT plot than in the soil samples from the CT and NT plots, as well as in the soil from plots after winter wheat than in that from plots after durum wheat, pea, and winter barley. Also, higher K and Mg contents were determined in the soil from the RT system compared to the CT and NT soil samples, as well as in the soil from plots after durum wheat than after pea, winter wheat, and winter barley.

Opis:
The yielding and yield quality are affected by interactions of complex dependencies between the plant, the habitat, and the agricultural practice. The goals of this study were to determine grain yield, grain quality, and winter wheat root infestation by Gaeumannomyces graminis var. tritici in crop rotation and monoculture. The experiment was established with the method of equivalent subblocks (25 m × 6 m) in three replications. The main experimental factor was the cropping systems (CS), and the second-order experimental factor was the tillage systems (TS). Winter wheat was sown in the following crop rotations: (i) CR-A: potato – winter wheat – peas – winter barley; (ii) CR-B: peas – winter barley – winter wheat – spring wheat; and (iii) MON: multi-year wheat monoculture. The following tillage systems were applied in CR-A, CR-B, and MON: (a) conventional tillage (CT); (b) reduced tillage (RT); and (c) no-tillage (NT). Wheat grain yield was affected by CS more than by TS; its highest value was recorded in CR-A followed by CR-B, whereas the lowest one – in MON. Higher grain yield was also obtained in NT and RT than in CT. The CR-A and CR-B as well as CT systems were found to elicit positive effects on the gluten content of wheat grain, grain weight per volume, Zeleny’s sedimentation index, grain uniformity, and ash content of the grain. Wheat root infestation by Gaeumannomyces graminis var. tritici was more severe in MON than in CR-A and CR-B, and in NT than in CT and RT.

Opis:
The objective of this study was to analyze the effect of different tillage systems on the yield, quality and mineral composition of grain of durum wheat. Three tillage systems were compared in the experiment: 1) conventional (CT), 2) reduced (RT) and 3) herbicide (HT). In the CT system, shallow ploughing and harrowing were performed after the harvest of the previous crop and late autumn ploughing was carried out before winter. In the RT system, double cultivation was performed instead of ploughing, whereas in the HT system the cultivation treatments were replaced by a herbicide containing a.s. glyphosate. In the springtime, a tillage set consisting of a cultivator, string roller and harrow was applied on all plots. Yields of wheat were higher in the years with high precipitation (years 2013-2014) than in the year with low precipitation (2015), as well as in the HT system than in the CT and RT systems. The content of total protein and wet gluten, as well as grain volume weight and grain uniformity were affected more by the study years than by the tillage systems. High sums of precipitation facilitated the accumulation of phytate-P and copper (Cu) in the grain, whereas the precipitation defict increased the content of potassium (K) and magnesium (Mg) in grain. The CT system contributed to the accumulation of phytate-P and iron, the RT system favoured the accumulation of calcium and manganese, whereas the HT system stimulated the accumulation of phosphorus, potassium, magnesium and copper in durum wheat grain.

Opis:
A strict field experiment was established in 1988 at the Uhrusk Experimental Station, belonging to the University of Life Sciences in Lublin, south-eastern Poland. Results pre- sented in this manuscript originate from the years 2006-2009, namely from 5 crop rota- tions and from a 16-20-year cereal monoculture. In a two-factor experiment, spring wheat of the cultivar Opatka was sown in different cropping systems. The first order factor in the experiment was the cropping system (CS): crop rotation (CR), and monoculture (M), whereas the second order factor were nitrogen doses: 90 kg N ha –1 , and 150 kg N ha –1 . The study demonstrated that wheat grain collected from CR was characterized by higher content of P, Ca, Fe and Zn compared to the grain harvested from M. Fertilization with 90 kg N ha –1 increased significantly the content of P, K, Ca, Fe and Zn in the grain compared to the fertilization with 150 kg N ha –1 . The cropping systems (CS) and nitrogen doses were observed to differentiate the content of protein and gluten in the grain. A higher content of protein was determined in the grain originating from M than in the grain harvested from CR. The content of protein and gluten was increased by the fertilization dose of 150 kg N ha –1 compared to the dose of 90 kg N ha –1.

Opis:
A study has been undertaken to determine the effect of different cultivation conditions for spring wheat cv. Koksa on the total ash, P, K, Mg, Ca, Fe, Zn, Mn, and Cu in wheat grain. The study was conducted at Uhursk Experimental Farm (51o18’12½N, 23o36’50½E) of the University of Life Sciences in Lublin, in 2008-2010. The experimental factors were: 1) systems of soil tillage: ploughing and ploughless, 2) doses of nitrogen: 90 and 150 kg ha–1, and 3) preceding crop: pea and soy. The objective was to evaluate the impact of different soil tillage systems, doses of nitrogen fertilizers and preceding crops on the content of mineral components in the grain of spring wheat cv. Koksa. The study demonstrated that ploughless tillage increased the content of total ash, Zn and Cu, while ploughing tillage raised the content of K, Mg and Mn in the grain. A standard dose of nitrogen (90 kg ha–1) facilitated the accumulation of K, Fe, Zn and Cu, whereas a higher nitrogen dose (150 kg N ha–1) elevated the content of total ash and Mn in grain of spring wheat. The grain of wheat cultivated after pea was characterized by a higher content of Ca, Fe and Zn, whereas that cultivated after soy contained more total ash, K and Mn.
Badano wpływ zróżnicowanych warunków uprawy pszenicy jarej odmiany Koksa na zawartość w ziarnie popiołu całkowitego oraz P, K, Mg, Ca, Fe, Zn, Mn i Cu. Badania prowadzono w latach 2008-2010 w Gospodarstwie Doświadczalnym Uhrusk (51°18’2”N, 23°36’50"E) należącym do Uniwersytetu Przyrodniczego w Lublinie. Czynnikami doświadczenia były: 1) systemy uprawy roli: płużny i bezpłużny, 2) dawki azotu: 90 i 150 kg ha-1, 3) przedplony: groch i soja. Celem badań była ocena wpływu zróżnicowanych systemów uprawy roli, wielkości dawek nawozów azotowych i przedplonów na zawartość składników mineralnych w ziarnie pszenicy jarej. Wykazano, że bezpłużna uprawa roli wpłynęła na zwiększenie w ziarnie zawartości popiołu całkowitego, Zn i Cu, natomiast płużna uprawa — K, Mg i Mn. Standardowa dawka azotu (90 kg ha—1) sprzyjała gromadzeniu w ziarnie K, Fe, Zn i Cu, natomiast wysoka dawka (150 kg N ha—1) zwiększała udział popiołu całkowitego i Mn. W ziarnie pszenicy uprawianej po grochu stwierdzono większą zawartość Ca oraz Fe i Zn, natomiast uprawianej po soi — więcej popiołu oraz K i Mn.

Opis:
Tillage systems determine conditions for plant growth and development, which undoubtedly influences the crop quality. The present study evaluated the mineral composition and content of phytate phosphorus, protein and starch in pea seeds under the conditions of conventional tillage (shallow ploughing and harrowing after harvest of the previous crop, ploughing in the autumn), reduced tillage (only cultivator after harvest of the previous crop), and herbicide tillage (only Roundup 360 SL after harvest of the previous crop). The study demonstrated a higher content of total ash, phosphorus (P) and potassium (K) in pea seeds from the conventional and reduced tillage systems as well as a higher content of calcium (Ca) in seeds from the reduced tillage compared to the herbicide system. The conventional tillage also increased the content of iron (Fe) compared to the reduced and herbicide systems. In turn, the content of magnesium (Mg) and zinc (Zn) did not depend on the tillage system or the study year, whereas the content of copper (Cu) was significantly higher in the reduced tillage compared to the conventional and herbicide systems. The content of phytate-P in pea seeds was affected only by the study year. The total protein content of pea seeds was similar in all the tillage systems and study years, whereas the starch content was higher in the conventional than in the reduced and herbicide tillage, and was also differentiated by the study year.
Uprawa roli kształtuje warunki wzrostu i rozwoju roślin, co niewątpliwie wpływa na jakość plonu. W badaniach oceniano skład mineralny, zawartość fosforu fitynowego oraz białka i skrobi w nasionach grochu siewnego w warunkach konwencjonalnej uprawy roli, uproszczonej i herbicydowej. Wykazano, że więcej popiołu ogółem, fosforu (P) i potasu (K) zawierały nasiona grochu z uprawy konwencjonalnej i uproszczonej niż herbicydowej, natomiast więcej wapnia (Ca) zawierały nasiona z uprawy uproszczonej niż herbicydowej. Konwencjonalna uprawa roli wpłynęła również na zwiększenie zawartości żelaza (Fe), w stosunku do uprawy uproszczonej i herbicydowej. Z kolei zawartość magnezu (Mg) oraz cynku (Zn) kształtowała się niezależnie od systemu uprawy roli i lat badań, zaś miedzi (Cu) była istotnie większa w uprawie uproszczonej niż konwencjonalnej i herbicydowej. Na zawartość P-fitynowego w nasionach wpływały tylko lata badań. Zawartość białka ogółem w nasionach grochu była podobna we wszystkich systemach uprawy roli i latach badań, zaś zawartość skrobi była większa w uprawie konwencjonalnej niż uproszczonej i herbicydowej. Cechę tę istotnie różnicowały również lata badań.

Opis:
The test material originated from a field experiment conducted in 2010-2013, at the Experimental Farm in Felin (51°22’ N, 22°64’ E), which belongs to the University if Life Sciences in Lublin. A two-factor experiment was conducted in randomised blocks with 4 replicates. The chemical composition of grain of 4 wheat species was analysed: common wheat (Triticum aestivum ssp. aestivum L.) cv. Tonacja, durum wheat (Triticum durum Desf.) cv. Komnata, spelt (Triticum aestivum ssp. spelta (L.) Thell.) cv. Schwabenkorn, and einkorn wheat (Triticum monococcum L.) line PL 5003 (material acquired from the National Centre of the Plant Gene Pool), grown at different production technology intensity (medium and high level of cultivation technology). The analyses on wheat grain included the content of total protein, crude ash, crude fat, crude fibre, carbohydrates, phosphorus, potassium, magnesium, calcium, copper, iron, manganese and zinc. The results were subjected to an analysis of variance, while the differences were estimated by the Tukey’s test at the significance level of p = 0.05. In order to identify the correlations and relationships between selected grain quality traits, an analysis of multiple correlation was employed and coefficients of variation were calculated (CV, %). Einkorn wheat proved to have the highest levels of protein, fat, ash, phosphorus, potassium, magnesium, calcium, copper, zinc, iron and manganese. Among the remaining genotypes, common wheat had the highest levels of carbohydrates and fibre. Irrespective of the genotype, more intensive chemical weed and pest control and nitrogen fertilisation had a favourable effect on the content of protein and fat, while reducing the levels of fibre and carbohydrates. Most of the macroelements, except phosphorus, and all the microelements reached higher concentrations under the more intensive production technology. In terms of grain quality, the response of the genotypes to the intensification of production technology was only slightly varied.

Opis:
In the study, the physiological response of wheat plants to the effect of metal salts was examined by measuring gaseous exchange transpiration parameters, such as transpiration intensity, stomatal conductivity and stomata count per 1 mm2 of the leaf under- and upperside. The study was carried out using the gley soil [black earth] of granulometric composition of loam collected from the plough-humus horizon of 0-10 cm depth. The soil was contaminated with different pollutant doses, i.e. 0 (control), 0.05, 0.5, 5 and 50 mmol·kg-1. Each combination was seeded with 10 wheat grains. Two-factor analysis of variance was used, with the type of applied salt (ZnSO4 and CuSO4) being the first factor and its dose the second one. The significance of factors was examined with Tukey's test (p<0.05). A delayed germination of seeds was observed in relation to the control in soil samples contaminated with 5 mmol·kg-1 (both salts). The seedlings examined showed large differentiation in their response to Zn and Cu; in the case of CuSO4, transpiration was much lower than under the effect of ZnSO4. The transpiration intensity was the lowest after application of copper salts in a concentration of 5 and 50 mmol-kg1, whereas the highest one was observed in zinc concentration of 5 mmol·kg-1. The soil contamination with a dose of 0.05 and 50 mmol·kg-1 resulted in a significant decrease of stomatal conductivity in relation to the control. The examined heavy metals significantly affected the stomatal count only on the leaf underside, where it increased at the highest concentration of heavy metals, i.e. 50 mmol·kg-1.
Reakcję fizjologiczną roślin pszenicy na działanie soli metali badano mierząc parametry wymiany gazowej, takie jak: intensywność transpiracji, przewodność szparkowa oraz liczba aparatów szparkowych na 1 mm2 dolnej i górnej epidermy blaszki liściowej. Badania przeprowadzono z użyciem czarnej gleby o składzie granulometrycznym gliny, pobranej z poziomu orno-próchniczego z głębokości 0-10 cm. Glebę zanieczyszczono różnymi dawkami polutantów: 0 - kontrola; 0,05; 0,5; 5; 50 mmol·kg-1. Do wszystkich wariantów wysiano po 10 nasion pszenicy. Zastosowano dwuczynnikową analizę wariancji: pierwszym czynnikiem był rodzaj zastosowanej soli (ZnSO4, CuSO4), a drugim dawka. Istotność czynników testowano testem Tukeya na poziomie 0,05. Zaobserwowano opóźnione kiełkowanie nasion w stosunku do kontroli w glebie zanieczyszczonej dwoma rodzajami soli w ilości 5 mmol·kg-1. Stwierdzono, że badane rośliny różnie reagowały na zastosowany metal. W przypadku soli miedzi transpiracja roślin była znacznie mniejsza niż w przypadku soli cynku. Intensywność transpiracji była najmniejsza po zastosowaniu soli miedzi w stężeniu 5 i 50 mmol·kg1, natomiast największe natężenie transpiracji wykazano po zastosowaniu soli cynku w stężeniu 5 mmol·kg-1. Zanieczyszczenie gleby dawką 0,05 i 50 mmol-kg-1 spowodowało znaczne zmniejszenie przewodności szparkowej w stosunku do kontroli. Badane metale ciężkie wpłynęły istotnie na liczbę aparatów szparkowych jedynie na dolnej epidermie blaszki liściowej, gdzie ich liczba zwiększyła się po zastosowaniu dawki 50 mmol·kg-1 metali ciężkich.

Opis:
The study evaluated the chemical composition of spring barley grain sown in 3 tillage systems (main plots): a) conventional tillage (CT) – shallow ploughing and harrowing after harvest of the previous crop, ploughing in the autumn; b) reduced tillage (RT) – only cultivator after harvest of the previous crop, and c) herbicide tillage (HT) – only glyphosate (360 g L -1 ) after harvest of the previous crop. In the springtime, a cultivation set composed of a cultivator, a string roller and a harrow was used on all the plots. The second experimental factor was barley cultivar (subplots): 1) husked Tocada, and 2) naked-grain Rastik. The depth of tillage varied according to the intended purpose: shallow ploughing to 10-12 cm, autumn ploughing to 25-30 cm, and cultivator tillage to 10-15 cm. The soil under the experiment was Chalk Rendzina with the texture of sandy loam, rich in available phosphorus and potassium and slightly alkaline. The study demonstrated that the content of total protein and crude fiber in the grain depended only on a barley cultivar. In turn, the content of macro- and microelements was affected by both factors: the cultivar and tillage system. Herbicide tillage (HT) was shown to reduce the content of phosphorus (P), potassium (K), calcium (Ca), iron (Fe) and copper (Cu) in barley grain, compared to conventional tillage (CT). Simultaneously, it raised the phytate-P content of grain compared to reduced tillage (RT). The content of phytate-P was significantly higher in cv. Tocada than in cv. Rustik.

Opis:
Fish are most often considered as a rich source of valuable fat, although sometimes the high quality of fish meat protein is also emphasized, but there is comparably little information on the mineral composition of fish meat. Chemical composition, caloric value and health safety of fish as food depend on many factors, of which the rearing conditions are most influential. Aside from environmental conditions, production technology is a major determinant of the quality and nutritional value of trout. In this study, the influence of a farming technology on the content of minerals in the muscle tissue of rainbow trout (Oncorhynchus mykiss Walbaum) netted in various Polish regions has been assessed. Fish were caught in autumn 2010 and 2011 and spring 2011, at 3 farms with a water flow-through system and 3 farms with water recirculation. The trout muscle tissue contained: 188.4 - 518.4 mg kg-1 of calcium, 306.9 - 338.1 mg kg-1 of magnesium, 464.0 - 718.2 mg kg-1 of sodium, 4.5 - 6.9 mg kg-1 of zinc, 2485.7 - 2823.6 mg kg-1 of phosphorous, 4261.2 - 4615.4 mg kg-1 of potassium, 3.0 - 9.4 mg kg-1 of iron and 0.09 – 11.74 mg kg-1 of copper. The farming technology influenced the content of calcium, sodium, zinc, iron and copper but had no effect on the content of magnesium, phosphorous and potassium in rainbow trout muscle tissue. Trout farmed in water recirculation systems contained higher amounts of most elements than the fish reared in water flow-through systems. The season of sample collection (date of netting) also affected the content of sodium, zinc, phosphorus, iron and copper. The fish farming site (localization of the farm) determined the content of most of the minerals except magnesium. Rainbow trout is a good source of phosphorous and potassium in a human diet, significantly covering the daily demand for the elements.
