The experiment included testing of rheological properties of dough as well as the baking quality of bread flour and bran obtained by grinding coloured wheat grains with purple pericarp (cultivars Rosso, Konini and PS Karkulka) and blue aleurone (cv. Scorpion). Common wheat cv. Mulan was used for comparison. Formulas containing 10, 15 and 20% of bran were prepared. The addition of bran increased the water loss during baking by an average of 1.28%, specific volume of bread decreased by 2 to 10 mL, and the ratio number decreased from 0.57 to 0.51. The dynamic oscillatory rheometry simulated processes occurring during baking. A higher content of bran increased...

The aim of the study was to determine the influence of amino acid fertilizer on yielding ability, morphological characteristics and chlorophyll index of timothy cv. Owacja grown for seed. The experiment was conducted in 2015-2017 at the Experimental Station in Prusy near Krakow, which belongs to the Institute of Plant Production of the University of Agriculture in Krakow. The field trial was set up as a randomized block design with four replications. The soil in the experimental field was a degraded chernozem formed from loess. The plots were sprayed with three doses of Microfert amino acid fertilizer: 1.8, 3.0 and 4.5 L/ha. The highest application...

Temporal changes in the concentrations of plant-available phosphorus (P) in soil (Olsen-P), total soil-P and P activation coefficient (the ratio of Olsen-P to residual-P (i.e. an approximation to total-P)) were measured in plots that received consistent inorganic nitrogen, phosphorus and potassium plus organic fertilizers annually. Maize and winter wheat crops were grown in rotation for 24 years. Olsen-P and P activation coefficient declined significantly in the earlier years (< 12 years) for treatments that did not include any P fertilizer, and increased over the same period for the P-fertilized treatments. The rates of change in the Olsen-P and...

Rational soil phosphorus (P) management is significant to crop production and environment protection. Little information is available on soil Olsen-P balance and critical values in double-crop rice in China. The main aim of the study was to relate soil Olsen-P to apparent P balance and to determine Olsen-P critical value for early and late rice using data from a 29-year study (1984~2012) at the Jiangxi province. The results showed that Olsen-P decreased by 0.12~0.26 mg/kg/year without P addition and increased by 0.56~2.52 mg/kg/year with P fertilization. Olsen-P decreased by 0.30 mg/kg for CK and NK under an average deficit of 100 kg P/ha, and increased...

The effect of sugar beet seed (primed and non-primed) on field emergence and root yield of sugar beet was examined. The experiment was realized in the years 2012-2014 at an Experiment Field Station of Warsaw University of Life Sciences - SGGW Faculty of Agriculture and Biology in Skierniewice (51°97'N, 20°19'E) in Poland. The experimental factor was diversified seed material of the same cultivar of sugar beet - typical seeds, traditionally prepared for sowing (non-primed seeds) and seeds before sowing, subjected to the process of priming. On average for the three years of the study, no significant effect of seed priming on the field emergence was found....

A whole-plant chamber system equipped with a transpiration sap flow meter was developed for measuring the transpiration rate even if leaves are wetted. A preliminary experiment in which dynamics of transpiration rate and/or evaporation rate of wetted and non-wetted plants were measured and compared with each other demonstrated the validity of the measurement system. The system was then used to analyse leaf wetting effects on gas exchange of corn under slight water stress conditions of soil (a volumetric soil water content of 9.7%). Leaf wetting decreased vapour pressure in leaves by decreasing leaf temperature but it increased vapour pressure in the...

To investigate the response of root architecture and nitrogen metabolism of apple rootstock to glucose supply in low-carbon (C) soil, Malus baccata (L.) Borkh. in gravel soil was treated with glucose C equal to the soil microbial biomass carbon (MBC)-C value (G1), five times the soil MBC value (G2), or with no glucose (CK). The roots samples were harvested after treatments for 7, 15 and 30 days. The roots tended to become larger, more dichotomous and showed a larger link branching angle in G1...
