Özet:

In this study, the blue separation (Agropyron intermedium (Host.) is grown in the conditions of erzurum break. Differential range (40, 80 and 120 cm) applied to Beauv.j and different doses of nitrogen (0, 5 and 10 kg Nida) and phosphorus (0, 25 and 5 kg P2Oj/da) have been studied the effects on the proportion of raw protein of the herb with dry herb and raw protein production. The results of this study, conducted in the period 1978-1984, are summarized as follows. The impact of the 1st edition has been significant. The highest dry herb productivity is 40 cm (302.8 kg/day), the highest raw protein ratio (13.34) and the raw protein productivity (375 kg/day) is taken from the processes applied in a range of 80 cm. The highest dry herb productivity (358.3 kg/day), raw protein productivity (52.8 kg/day) and raw protein ratio (% 1450) were obtained from the application of 10 kg Nida. The effect of phosphorus on dry herbs is important, but the effect on raw protein and its yield is not important. The highest dry herb production (2665 kg!da) is taken from the processes applied at 2.5 kg P205/da. The Effects of ROW SPACING, NITROGEN AND PHOSPHORUS ON HAY AND CRUDE PROTEIN YIELDS AND PERCENTAGE OF CRUDE PROTEIN IN INTERMEDIATE WHEATGRASS (Agropyron intermedium (Host.) by Beauv.) GROWN UNDER DRY CONDITIONS OF ERZURUM SUMMARY T his trial was established on the dry experimental areas of Agricultural Faculty of Atatürk University, Under dry condition, three row spacings of 40,80 and 120 cm and nine combinations of three nitrogen(0,5 and 10 kg N/day) with three phosphorus (0,25 and 5 kg P2O5/day) concantrations were used. The effects of the treatments on the hay, protein content of hay, and protein yield were studied throughout the 1978-1984. The results obtained in this study can be summarized as below. The ejfect of row spacing was significant on protein and hay yieîds, and portein content. The highest or yield (302.8 kg/day) was obtained with 40 cm row spacing. The highest raw protein yield (375 kglda), and protein content (% 13.34) was obtained at 80 cm spacing. 2- The highest hay (358.3 kglda), and raw protein yields (52.8 kglda), and protein content (1450%) were detertrdned at 10 kg Nida treatment. The effect of phosphorus was significant on hay yield. The highest or yield (2665 kglda) was obtained at 2 5 kg P20olda treatment. No effect of phosphorus on raw protein yields and protein content of hay occured.
