The influence of the fertilizers of various action on the growth and development of the plants of Barenburg Sport grass mixture

The research objective was to define the influence of prolonged fertilizers of different structure on the stand quality. The research problems were to estimate the quality of herbage and to define the influence of various fertilizers on the growth aboveground and underground parts of turf grass. The experiment consisted of 10 treatments (control - without fertilizers and 9 different fertilize treatments) in 3-fold frequency. One plot size made 1 square meter. The research object was Barenbrug Sport turf grass mixture. The method of turf grass ornamental characteristics evaluating by the A. A. Laptev (1983), which included analyzing turf grasses for tillering productivity and grass density; and the Method of evaluating turf grass ornamental characteristics by NTEP method were used. The greatest number of roots was observed on the allotments, with the fertilizers introduced on them: azofoska (7.4 pieces), Maintenance (10.2 pieces); the small quantity of roots was observed on a control allotment without application of fertilizers (3.2 pieces) and with the brought potassium (7 pieces). The assessment of general decorative effect of turf grass carried out on the basis of the addition of herbage and projective covering on a 5-mark scale. The majority of herbs had either single and separate (1 point), or separate and group (2 points) herbage addition, except the allotment with the Flora fertilizer - mosaically group (3 points). The results of the assessment of theefficiency of shooting: on average the majority of herbs had the point 2.3 (on a 6-mark scale), the herbs on the allotment where azofoska was brought (N-P-K - 16:16:16) - 2.7, and the highest point had the allotment with the Flora fertilizer introduced on it have high point. On average the majority of herbs had point 7 according to the characteristic "color" (on a 8-marks scale), two allotments had point 7.3 (New grass, Full season) are the highest rates on color. According to the characteristic "density" the highest point has herbage on the allotment with the Stress control (8) fertilizer, the smallest - on the control allotment (4.4). The application of ammonium nitrate phosphate fertilizer and Maintenance slow-release fertilizer can be recommended for using because they are complex and include all the necessary nutrients for gramineaus plants. The Landscaper pro Flora fertilizer had also positive impact on many indicators of herbage quality.
