The crop suitability is the process of assessing the appropriateness or ability of a given type of land on the basis of growing conditions of a particular crop. The study focused on the crop suitabili...
Maximum aphid numbers on wheat are positively related to the length of the period elapsed from immigration to the population peak. We predicted that maximum abundances on late maturing cultivars would...
Information on the effects of different yeast species on ruminal fermentation is limited. This experiment was conducted in a 3×4 factorial arrangement to explore and compare the effects of addition of...
The aim of this study was to determine the effect of whole maize and oat grains contained in starter concentrates on the performance of calves (during the first 90 days of their life) and selected mor...
An in vitro method was used to determine ruminal degradability of starch (IVRDS) in a set of cereal grains. The set included 9 feed samples, including 2 samples of ground wheat, 2 samples of wheat tre...
Our research was realised on spring barley and winter wheat in Nitra-Dolná Malanta during 2004–2006. We found that the total occurrence of the pests had decreasing tendency. The flea beetle (Phyllot...
Cereal leaf beetles are serious animal pests of crops in many areas of western and eastern Slovakia. Research was carried out in these areas in order to receive knowledge on occurrence of natural en...
The abundance of cereal aphids on winter wheat tillers and ears was determined in two field managements (integrated and ecological) at Dolná Malanta, Slovakia, over the years 1999–2001. The overall av...
The level of parasitism of cereal aphids on winter wheat at growth stage 69 DC (end of bloom) differed between two field management used (integrated and ecological) and between individual years of the...
During 1997–1999, occurrence of hymenopteran parasitoids of cereal aphids was observed in different localities in Slovakia. Altogether, seven species of aphid parasitoids were recorded. The total numb...
Population growths of three aphid species colonising winter wheat stands, Metopolophium dirhodum, Rhopalosiphum padi and Sitobion avenae, were analysed by regression method. The calculations were base...
Intercropping of grain legumes and cereals is a promising theme in organic farming for its potential for increasing and stabilizing yields, reducing weed pressure and sustaining plant health. On anima...
AACC International is a global, nonprofit association of nearly 2,500 scientists and food industry professionals working to advance the understanding and knowledge of cereal grain science and its prod...
Field experiments carried out in the 2005–2007 time period were aimed at assessing the use of competitive potential against weeds of spring cereals cultivated in mixtures, for the purpose of reducin...
The long-term success of hydrogenase uptake negative legume-rhizobia associations, in spite of their apparent inefficiency, may be explained by the positive effects of H2 release to soil. A primary be...
