Annual N2O flux was higher in grassland than in cornfield, and it was higher in MF plot (14.9 kg N/ha/period) than in F plot (11.1 kg N/ha/period) in grassland. However, in cornfield, the annual N2O flux was equal between both plots (5.6 kg N/ha/period). These results clarified that high nitrogen application was not always responsible for the high soil N2O flux. N2O flux was significantly correlated with air, soil temperature and water-filled pore space. More than 80% of the annual N2O flux occurred before freezing and less than 4% during melting period. Denitrification was the main process of N2O flux during study, it was evidenced by the distribution of N2O and NO ratio which is from 1 to 1000. The denitrification activity (DEA) potentially increased in grassland soil in the beginning and the end of winter season when NO3-N was abundant; on the other hand the abundance of carbon potentially increased DEA in cornfield soil.

Prokeš Author-Workplace-Name: Research Institute of Brewing and Malting, Brno, Czech Republic Title: The effect of weather and the term of malting on malt quality Abstract: The effect of the weather on the physiological and malting parameters of spring barley was studied. The dependence of malt quality on the course of weather during the caryopsis growth and development in the ear was statistically confirmed. Germinating caryopses responded statistically significantly to a higher sum of precipitation over the entire growing period (r = -0.48), and higher temperatures (r = -0.43) and radiation (r = -0.43) in the 14-day period before harvest by a lowered ethylene production, malting yield increased with the reduced ethylene production (r = -0.35). Reduced content of carbon dioxide released by germinating caryopses depended highly statistically significantly on higher temperatures (r = -0.86) and radiation during 14 days before harvest (r = -0.88). β-glucan content in wort (r = 0.50) and malt modification (r = -0.21) depended statistically significantly on the precipitation sum over the entire vegetation period (the more precipitations, the lower β-glucan content). Malt modification was in positive statistically significant correlation with the sum of temperatures (r = 0.46) and radiation in the 14-day period before harvest (r = 0.39).

Bojos. The following parameters were studied, the effect of fertilization on grain yield, specific weight, percentage of the grain retained on a 2.8 mm and 2.5 mm sieve, the content of starch and proteins, and the percentage of protein fractions. Also the influence of weather conditions on the studied parameters was evaluated. Starch content and specific weight of grain were not influenced by the fertilizer applied. Grain yield was rising until the overall dosage reached 50 kg N/ha and 21 kg S/ha while any higher rate of fertilizer reduced the yield. The percentage of A- and B-hordeins increased and the content of C- and D-hordeins reduced as the fertilizer rate increased. A significant effect of weather on the monitored parameters as well as on the percentage of protein fractions was demonstrated. The results enabled a conclusion that there is no improvement in technological quality of barley grain once the optimal rate of fertilizer has been reached. The optimal rate is influenced by weather conditions during the growing season.

The microbial biomass in the lagg fen was not greater than that of the mineral soil or the mire expanse, but the respiration rate of the decomposer organisms in the lagg fen exceeded that of either the mire expanse or surrounding mineral soils. The respiration rate of microorganisms in litter recovered from litter bags in the lagg fen was greater than that in the mire expanse, and the microbial biomass of the litter was greater for the lagg fen than for either the mineral soil or the mire expanse. Further, the litter from minerotrophic plants decomposed faster than the ombrotrophic species.

This paper describes how Landsat satellite data can be used to derive a growth model calculated from normalised difference vegetation index that can predict winter wheat (Triticum aestivum) and winter oilseed rape (Brassica napus) phenological state using the Biologische Bundesanstalt, Bundessortenamt und Chemische Industrie scale. Time series of Landsat images were chosen from the years 2004, 2008 and 2012, when winter oilseed rape was grown, and 2005, 2009, 2011 and 2013, when winter wheat was grown in the same experimental field. The images were selected from the whole growing season of both crops. An advantage of this method is the easy availability of the remote sensing and its easy application for deriving a prediction model from vegetation indices. Our results showed that Landsat images, after correct pre-processing, can be used for winter wheat and winter oilseed rape growth model prediction.

Yield potential was evaluated at harvest time in physiological maturity of crop stand. The results confirm that total yield and yield of tubers > 40 mm of coloured potatoes cvs. Red Emmalie/r (68.98 t/ha), Blaue Elise/p (59.96 t/ha), Valfi/p (53.72 t/ha) were comparable with control cvs. Agria/y, Lady Balfour/w and Russet Burbank/w. Some cultivars with lower yield had share of tubers above 40 mm comparable with control cultivars (94.45% and 93.48% in case of cvs. Valfi/p and Blue Congo/p), respectively. Antioxidant activity was determined as ascorbic acid equivalent by ABTS (2,2´-azinobis (3-ethylbenzothiazoline-6-sulfonate) method. The lowest antioxidant activity was observed in the control cvs. Lady Balfour/w (ascorbic acid equivalent (AAE) 74.1 mg/kg fresh mattter (FM)), Agria/y (AAE 84.4 mg/kg FM) and Russet Burbank (AAE 93.9 mg/kg FM). In the group of cultivars with red flesh AOA was 3.2 to 5.1 times higher and in a group of purple-fleshed cultivars it was from 3.7 to 7.0 times higher.

The study included three sowing densities: 60, 75 and 90 germinated seeds/m2. The cultivars of white lupin achieved significantly higher seed yield, higher 1000 seed weight, higher weight of seeds per plant and higher protein content in the seed, compared to the cultivar of narrow-leafed lupin. The sowing density had no effect on seed yield, but the increase in sowing density above 60 germinated seeds/m2 significantly reduced the number of pods, the number of seeds and seed weight per plant.

The effect of intensification of cultivation technologies on the yield of morphologically diversified cultivars of white (Lupinus albus), yellow (L. luteus) and narrow-leafed lupin (L. angustifolius) was examined. Traditional cultivars of white and yellow lupin gave significantly higher yields than the self-completing ones, as opposed to narrow-leafed lupin in which the self-completing cultivar had higher yields. Increasing expenses on industrial production means caused an increase in the yield of all the studied species. Seed yield of white and narrow-leafed lupin was significantly the highest in high-input technology, while that of yellow lupin in high- and medium-input technology. In all lupin species, insignificant diversification was observed in the number of pods per plant in medium- and high-input technologies as well as in low- and medium-input technologies. A significant increase in the seed yield along with an increasing intensity of the cultivation of traditional and self-completing cultivars of white and yellow lupin, as well as self-completing cultivars of narrow-leafed lupin, resulted mainly from developing a higher number of pods.
