The aim of the study was to evaluate the effect of diversified nitrogen fertilization doses and application of various doses of herbicide Starane 250 EC on the total protein efficiency and carbohydrate:protein ratio of meadow sward. Two-factor field experiment was established on permanent meadow in the spring of 2007 in Żelków near Siedlce in a randomized subblock design in three repetitions. First...
Research was carried out in years 2007-2009 on the basis of field experiment in split-plot design, in three repetitions. Monoculture lawn was set up for the experiment. In pure sowing, four species of lawn grass were studied: perennial ryegrass, red fescue, common meadow-grass, and common bent. In the experiment, the following factors were applied: bedding type: a – no hydrogel „0” – control plot;...
Using in substrates superabsorbents, also called hydrogels, contributes to considerable savings of water. Lawn turf quality depends largely on frequency of watering, having the effect on financial savings while incurring expenses connected with management of turf lawns. The aim of this study was to assess wintering of different turf lawns depending on the depth of placing hydrogel in the substrate...
The study was carried out on the basis of two lawn experiments, which were founded in the split-block split-plot with four replications. The experimental unit was a plot with an area of 1 m2. For investigate purposes was detailed the kind of the lawn and was called it as monoculture (pure sowing) and-mixed. The criterion for the division of mixtures was sharing of red fescue in sowing. In pure sowing...
The effect of pH of the growing medium on germination and initial development phases of seedlings of four plant species: Festuca pratensis Huds. and Dactylis glomerata L., Trifolium repens L. and Medicago sativa ssp. falcata × ssp. sativa L. in hydroponic cultures was investigated. Hoagland growing media with pH: 6.5; 6.0; 5.5; 5.0; 4.5; 4.0 were used. In this study we determined the germination energy...
The aim of this study was to determine the effect of superabsorbent and mineral fertilizers on coloring of lawns. The study was conducted in the years 2002-2004 and included two lawn experiments which were established in the split-block split-plot design with four replications. The experimental unit was a plot with an area of 1 m2. One experiment involved monoculture lawn turf (pure sowing). The other...
