Three non-food cultivars of winter wheat (Biscay, Clarus, Rapsodia) were grown at four locations in the Czech Republic with different agro-ecological conditions in the years 2005-2008 and two levels of nitrogen fertilization - 90 and 120 kg N/ha were used. The influence of growing conditions (year, location, cultivation technology) on grain yield, starch content, protein, gluten, share of amylose in starch, falling number and amylographic characteristics. All qualitative indicators were significantly affected by the weather. Wheat grown in the areas 500 m a.s.l. had lower grain yield of 2.8 t/ha (8.4 t/ha), higher starch content of 2.1% (69.0%) and...

A field experiment was conducted on rendzina soil in the years 2010-2012. The seeds of two linseed cultivars (Szafir and Oliwin) were sown at row spacing of 15 cm and 25 cm. Three agrotechnical levels in different nitrogen doses and with or without application of herbicides were used. The objective of the study was to evaluate the effect of row spacing on yield, seed protein and oil content of two linseed cultivars grown under different conditions of mineral fertilization and chemical weed control. Results showed that cv. Szafir was characterized by significantly higher seed yield (on average by 20.2%) and protein content (by 2.6%) while cv. Oliwin...

The effects of different modes of straw mulch on soil water storage, grain yield and water use efficiency (WUE) of spring maize (Zea mays L.) were evaluated from 2007-2010 at the Dry Farming Base of Northwest A&F University, in the Loess Plateau of China. Seven treatments were conducted, including conventional tillage without straw mulch (CK), maize straw mulch for the whole year (WSM) at the rates of 4 500, 9 000 (S2) and 13 500 kg/ha (S3), and maize straw mulch only during growth period (GSM) at the rates of 4 500, 9 000 and 13 500 kg/ha. The results showed that the 3-year average soil water storage within the 200 cm soil depth for the...

Winter Orychophragmus violaceus (OV)/spring maize is a novel eco-agricultural system in North China Plain, but little is known about OV's nitrogen (N) effects on succeeding maize growth and its contribution to maize N uptake and utilization during the growth. A pot experiment using 15N was conducted, including five treatments: (1) Control - without OV incorporation and N fertilizer; (2) G - high 15N labelled-OV incorporation; (3) 50%G - lower 15N labelled-OV incorporation; (4) F - 15N labelled urea fertilizer merely; (5) G + F - high OV incorporation combined with urea fertilizer. Increasing OV incorporation...

The aim of this study was to determine the effect of sulphur (S) fertilization on macronutrient concentrations in the roots, straw and oil cake of white mustard and Indian mustard. The experiment was conducted in northeastern Poland (2006-2008). The highest content of N, P, K, Mg and S was noted in the oil cake of both mustard species. Sulphur fertilization increased S concentrations and had no effect on Mg concentrations in the roots of white mustard and Indian mustard. Sulphur fertilizers applied to soil significantly increased the content of N, K and Ca in the roots of Indian mustard, whereas they had no significant effect on the content of N, P...

This study was aimed to determine the impact of risk element content on the prevalence of the selected microbial groups in industrial soils of one of the steelworks in Poland. The concentration of heavy metals: Cd, Cr, Cu, Hg, Fe, Ni, Pb and Zn along with soil pH and the number of mesophilic bacteria, fungi, actinomycetes and Azotobacter was assessed in 20 soil samples. The limit concentrations of Cd, Pb and Zn were exceeded in five sites. However, even in these strongly contaminates sites, the studied microorganisms were abundant. The correlation between the concentration of heavy metals and microbial numbers was very weak and statistically...

In three-years experiments soya seeds were treated with biologically active compounds: Lignohumate B (mixture of humic and fulvic acids), Lexin (mixture of humic and fulvic acids enriched by auxins), brassinosteroid (syntetic analogue of natural 24 epibrassinolide) and so-called complete seed treatment (mixture of saturated solution of sucrose, Lexin, fungicide Maxim XL 035FS and adjuvant on the base of pinolene Agrovital). During vegetation following characteristics were observed: field germination, density of vegetation after germination and before harvest, height of plants, height of apical part of the lowest pod from the ground and yield. The results...

Changes of amino acid (AAs) contents (glutamic acid - Glu, aspartic acid - Asp) and fatty acids profile (FAs) in spinach under cadmium (Cd) soil contamination (Cd1 = 30, Cd2 = 60, Cd3 = 90 mg/kg soil) are reported here. Spinach plants were sampled 25, 40, 55 and 75 days after sowing. Growing Cd soil contamination was associated with the strong inhibition of above-ground biomass (23.5-6.3 g dry matter per pot) and with the enhancement of Cd content (0.60-72.38 mg/kg dry matter) in leaves. During 55 days of plant growing the increase of Glu and Asp content was associated with the enhancement of Cd content. The highest accumulation of AAs was determined...
