GRASSLAND MANAGEMENT FOR HIGH FORAGE YIELD AND MINERAL COMPOSITION IN KOSOVO

Wild grass communities may play an important role for natural and seminaturalgrassland quality, but other plant species present in botanical compositionmay affect both yield and quality negatively. The field experiment were carriedout on a field study was conducted in the central part of Kosovo, respectivelyLipjani location 15 km near the capitol city of Prishtina. The area is characterizedby flat topography; black soil (smonica, vertisol) is the dominant soil type. Thefield survey was carried out during year 2012 with aim of determining the fresh,draw yield per unit area (m^2) and mineral composition in grassland includeimportant elements; Iron, Calcium, Cupper, Magnesium, Zinc etc. Theexperiment was designed as a randomized complete with four replication. Theplot sizes were 81.5x 8m per plot or 12 m2. The fertilization also was used inquantity 80 kg N ha -1. In experiment was including four treatments: C- Control(normal cutting without harrowing); Cutting regime include; A-One week earlywithout harrowing, B- One week later without harrowing and H-With harrowing.The results for quality traits include Fresh weight (FW) and Dry weight (DW)from our results reported with wide genetic variation and showed a significanteffects for level of probability LSDp=0.05. The results were obtained in ourstudy demonstrated that substantial differences in mineral composition exist ingrasslands. The four treatments had considerable variation in mineralcomposition. The Aluminum (Al) and Calcium (Ca) content ranged from 0.36 to0.19 and 5.07 to 7.31 g kg-1 respectively. The analysis of traits according toPearson correlations, are ascertained variable values of the phenotypic correlationcoefficient.
