Özet

This study was carried out between 2004-2005 in a natural meadow at Arusu village within the boundaries of Van province to investigate the effects of different doses of azote and phosphate on botanic quality of the meadow and quality of the grass. In this study, which was conducted as three repeating according to factorial trial design in random blocks, azote is applied in 0, 4, 8 and 16 kg day(-1) doses while, phosphor is in 0, 6 and 12 kg day(-1) doses. In the 1st year of trial, the effects of azote fertilizer on legume plants are found insignificant while, it was found to be significant on other criterions. In the 2nd year, its effect on all criterions studied was found to be significant. In the 1st year, the highest grain amount was found 4 kg day(-1) (88.3%); plant amounts belong to other families to be 16 kg day(-1) (17.3%) and raw protein amount to be 16 kg day(-1) (11.7%), which was obtained by azote applications. In the 2nd year, the highest legume amount was found to be 27.6%, plant amounts belong to other families to be 16.5% and raw protein amount to be 12.0% in parcels without azote application and in the places with azote application, grain amounts are determined from 16 kg day(-1) azote application (88.6%). In the 1st year of phosphor fertilizer trial, significant effects are found on plants belong to other families and insignificant effect found on other criterions studied. In the 2nd year of trial, insignificant effects are found on plants belong to other families and significant effects found on other criterions studied. In the year 2004, the highest plant ratio (15.9%) belongs to other families was obtained from parcels without phosphor application. In the 2nd year, the highest legume ratio (24.3%) was get from parcels with 6 kg day(-1) phosphor application, grain ratio (84.3%) in parcels without phosphor application and raw protein ratio (12.1%) was obtained from parcels with 12 kg day(-1) phosphor application.
