Abstract:
... The influences of arbuscular mycorrhizal (AM) fungus on growth, gas exchange, chlorophyll concentration, chlorophyll fluorescence and water status of maize (Zea mays L.) plants were studied in pot culture under well-watered and drought stress conditions. The maize plants were grown in a sand and black soil mixture for 4 weeks, and then exposed to drought stress for 4 weeks. Drought stress signific ...

Abstract:
... To develop rainfed agriculture in northern China, we conducted field experiments with three straw mulching rates (0, 6, and 12 t/ha) on two plant types (a compact type, Chaoshi1, and a flat type, Danyu86) during the summer maize-growing season in 2009 and 2010 to study soil moisture content, evapotranspiration, grain yield, and water-use efficiency (WUE). The results indicated that straw mulching ...
... In the present study the impact of beauvericin (BEA) on the cell membrane properties and respiration of young initial leaves of maize were studied using two maize cultivars differing in their susceptibility to Fusarium sp. BEA significantly depolarized EM of leaf parenchymal cells and this depolarization showed time and dose dependency regardless on the sensitivity of maize cultivars to ...

Abstract:
... A field experiment was conducted on a chernozem soil to estimate fertiliser N efficiency of silage maize (Zea mays L.) by the difference method as influenced by the type of N fertiliser (mineral-MF vs. sewage sludge-SS), and N rate. Eight N treatments were included (0, 60, 120, 180, and 240 kg N/ha prior to maize sowing, 60 kg N/ha at planting in MF; 120, and 240 kg N/ha in SS. The average dry mat ...
... A field experiment was conducted in order to estimate the influence of different arrangement patterns of maize plants (Zea mays L.) in combination with low rates of herbicides on weed infestation and on production parameters of the crop. The maize was sown at 70-, 50-, and 35-cm row space with the same crop density. The weed biomass declined with smaller row spaces and was, on average, the lowest ...
... A two-factorial experiment was carried out on 6 groups (10 animals each) of Polish Black and White Holstein-Friesian cows in the transition period to determine the effect of glucogenic additive (GA) to the diets containing grains of varied ruminal starch degradation on cow performance. The animals from 3 control groups (C-groups) were fed the diets without any additive, whereas 3 other, expe ...
... The application of Thamnidium elegans fungal strain CCF 1456 (TE) for effective utilization of various agroindustrial materials creates new perspectives for animal cereal diets enriched with microbial γ-linolenic acid (GLA). Diets consisting of lucerne hay (LH) plus prefermented cereals (wheat bran/spent malt grains, WB+TE or WB+TE enriched with sunflower oil, WB+SO+TE in the first experimen ...
... The baking quality in the sets of both commercial and variety wheat samples (80 and 18 items) and wheat composite flour (standard and 25 blends) was evaluated in terms of the Solvent retention capacity method (AACC 56-11). Composites were prepared from a commercial fine wheat flour and commercial bio-wholemeal flour prepared by milling of common wheat, rye, oat, barleys and corn at substitution le ...

Abstract:
... Corn (Zea mays L.) growth and development is often limited by the availability of phosphate. We thus hypothesized that phosphate fertilization may increase the contents of (poly)phenols, carotenoids, and tocochromanols (vitamin E) in corn grains. Corn plants cultivated on a soil fertilized with 44 kg phosphorus/ha were compared to plants grown on soil with low plant-available phosphate (1.6 mg CAL ...
... In response to insect feeding, corn plants (Zea mays cv. Delprim) release elevated levels of volatile organic compounds (VOCs), including the C6-volatile (Z)-3-hexenol. The level of mRNA accumulation for a series of defense genes was monitored in response to application of (Z)-3-hexenol (50 nmol) to undamaged plants. The induction of transcripts for hpl (hydroperoxide lyase), fps (farnesyl pyropho ...
... Rice (Oryza sativa) is the staple food for over half the world’s population. Drought stress imposes major constraints on rice yields. Intriguingly, labdane‐related diterpenoid (LRD) phytoalexins in maize (Zea mays) affect drought tolerance, as indicated by the increased susceptibility of an insertion mutant of the class II diterpene cyclase ZmCPS2/An2 that initiates such biosynthesis. Rice also pr ...
... In this study, Streptococcus thermophilus and Lactobacillus bulgaricus were used to produce L(+)-lactic acid by simultaneous saccharification and fermentation (SSF). The use of hydrolyzed yeast as cheap nutrients and mixtures of cellulosic materials and starchy materials as carbon source for L(+)-LA production was evaluated. Heat treatment (121 °C) was proven to be an effective method to improve t ...

Abstract:
... Soil structure is a key characteristic of soil functioning. More, silt and clay-sized organo-mineral fractions are usually considered as the most reactive soil fractions. As transmission electronic microscopy (TEM) appeared to be well-suited to study soil microstructures, it was used to test the sensitivity of micro-aggregates to land use and cultivation practices. The aims of this study were ther ...
... Previous research in our laboratory demonstrated marked increases in phytate P utilization when P-deficient corn-soybean meal diets were supplemented with 1a-hydroxycholecalciferol [1alpha-(OH) D3] and fed to chicks. Our objective was to determine if 1alpha-(OH) D3 would improve phytate P utilization when supplemented to vitamin D-adequate laying hen diets. The five experimental treatments were 1) ...
... Soil salinity is a wide-reaching environmental problem that lowers the yield of commercial crops such as maize, rice, and sugarcane. In this study, we examined the effect of 1-aminocyclopropane-1-carboxylate (ACC) deaminase-producing endophytic diazotrophic Enterobacter sp. EN-21 on growth promotion, salt tolerance, and root colonization of sugarcane. Enterobacter sp. EN-21 inoculated and uninocul ...
... A very small scale laboratory procedure (approximately equal to 10 g) is needed to test wet-milling characteristics of corn when amounts of corn available for testing are quite limited. The objective of this study was to downscale 100-g laboratory wet-milling methods already widely used to measure wet-milling properties of 10 g of corn. A Standard 100-g procedure, a Modified 100-g procedure, and a ...
... Dry matter intake (DMI) by horses and cattle is known to be affected by seasonal weather changes. Also, voluntary DMI differs among herbivore species. The study objective was to compare changes in voluntary DMI of cattle and horses fed a similar forage diet to changes in temperature (TEMP) and precipitation (PRECP) during summer-fall season in Central Kentucky, USA. Twelve Holstein steers particip ...
... Long-term management systems cause changes to soil physical properties that may affect soil erosion and erodibility. A study was conducted to evaluate the effects of 125 years of continuous crop management on Sanborn Field for selected soil physical properties. Intact soil cores were collected from continuous corn (Zea mays L.), continuous wheat (Triticum aestivum L.), continuous timothy (Phleum p ...
