The Effect of Cuting Frequency and Height on The Hay Yield and Some Chemical Characteristics of Hay in Diploid and Tetraploid Perennial Rye (Secale montanum Guss.)
This study was carried out under greenhouse conditions from March 1995 to August 1996. The effects of cutting frequency and height on hay yield and quality were investigated. In this research, 2 ploidy levels (diploid and tetraploid), 3 cutting frequencies (4, 6 and 8 week intervals) and 3 cutting heights (0, 5 and 10 cm) were investigated and analyzed in three factorial completely randomized design. In diploids, tiller numbers per plant were higher than that of tetraploids, whereas green and hay yields, the percentage and yield of crude protein were lower than that of tetraploids. There were no significant differences between diploid and tetraploid ryes for the percentages of Ca, Mg, K and P. Cuttings from ground level (0 cm) and lower intervals (4 week) significantly decreased tiller numbers per plant, plant growth speed, green and dry hay yields and crude protein yield. As cutting height increased, the percentages of Ca, Mg, K and P also increased. The longer cutting intervals increased the percentages of Ca and Mg, and but decreased the percentages of K and P.
