The results of three-year trials (1999 to 2001) conducted with six winter wheat varieties in which was investigated the effect of sites, years and varieties on the final grain yield and technological quality showed statistically significant differences (LSD, 95%) among sites in grain yield and these parameters of quality: test volume mass, wet gluten content, sedimentation test, protein content, falling number and flour water absorption capacity. As to the quality, the ®atec site showed itself as generally most suitable, and the Jaroměřice site as the least suitable one. Climate conditions showed a statistically significant effect (LSD,...

Modeling preferential flow has been a concern of many academic fields in the past 30 years all over the world and helps to prevent groundwater contamination. A dual-porosity model, MACRO, was evaluated for short-term (less than 2 days) simulation of water flow and non-reactive solute (chloride) transport through the profile of six plots in well-structured Maury silt loam soil. Water flow in micropores is calculated by the Richards' equation while simple gravity flow is assumed in the macropores. Solute transport in the micropores is calculated by the convection-dispersion equation (CDE) while the dispersion and diffusion in the CDE is neglected for...

During 1993-1995 the effect of conventional tillage, reduced till, mulch till and no-till technology on soil moisture dynamics has been studied in field experiment on Haplic chernozems near Pieą»any. The tillage treatments were evaluated under a single cropping of maize and spring barley - common peas - winter wheat crop rotation. Soil samples for gravimetric determination of moisture content were collected from six layers up to 0.8 m, three times per year (April-July). The soil moisture was highly significantly influenced in order of importance by date of sampling, year, growing crops, tillage treatments, soil layer and by interactions year × crops,...
Forage characteristics of Vicia sativa L. and Trifolium resupinatum L. in catch crop systems under Central European conditions

Plant Soil Environ., 2005, 51(3):131-136 | DOI: 10.17221/3565-PSE
In a field experiment the development of dry matter yield and forage quality of the catch crop Vicia sativa L. compared with Trifolium resupinatum L. was investigated and the suitability for cultivation in a mixture with Lolium multiflorum ssp. gaudinii (Parl.) Schinz et Keller was tested. The legumes and mixtures sowed in early July or August, respectively, were harvested at different dates from early September until late October/early November. The sowing date had the greatest impact on dry matter yield, crude protein content and net energy for lactation (= NEL). Vicia sativa yielded more dry matter than...
Conservation effects on the botanical composition of grass swards in the hilly soils of West Lithuania

Plant Soil Environ., 2005, 51(3):137-143 | DOI: 10.17221/3566-PSE
Four conservation methods were compared on grassland unused for 30 years: 1. control (unused grassland); 2. one cut, herbage mass was spread for mulch; 3. one cut, herbage mass was removed; 4. two cuts, herbage mass were removed. Experiments were carried out during 1996-2000 at the Kaltinenai Research Station of the Lithuanian Institute of Agriculture in a hilly region of the Zemaiciai Uplands of West Lithuania, on a hilltop and hill slope. During the experimental period an increase in the number of shoots of each botanical group (grasses, legumes and forbs) were identified in all treatments. The highest increase in the total number of grass shoots...
The influence of the year, fore-crops and fertilisation on yield and content of crude protein in spring barley

Plant Soil Environ., 2005, 51(3):144-150 | DOI: 10.17221/3567-PSE
In the years 2001-2003 in field trials we studied the effects of the conditions of year, fore-crops (winter wheat, sugarbeet, grain maize) and optimalization of the nutritional status on the yield and crude protein content in the grain of spring barley. From the analysis of the plants we can see that dry matter production and nutrient concentration in the plants were influenced by the conditions of the year and the fore-crop. After sugar beet, the growth of the dry matter was intensive and the concentrations of nutrients per one plant were higher as early as in the initial stages of vegetation. The yields in the years 2001 and 2002 corresponded with...
