ÖZET
Bu araştırmada, Erzurum kıraç şartlarıda yetiştirilen mavi ayrık
(Agropyron intermedium (Host.) Beauv.j'a uygulanan değişik sıra aralığı (40, 80 ve 120
cm) ile farklı azot (0, 5 ve 10 kg Nida) ve fosfor (0, 25 ve 5 kg P2Oj/da) dozlarının
kuru ot ve ham protein verimi ile otun ham protein oranına etkileri incelenmiştir.
1978-1984 döneminde yürütülen bu araştırmadan elde edilen sonuçlar, aşağıdaki şekilde
Özetlenmiştir.
1- Sıra aralıklarının etkisi önemli olmuştur. En yüksek kuru ot verimi 40 cm
(302.8 kg/da), en yüksek ham protein oranı (% 13.34) ve ham protein verimi (375
kg/da) ise 80 cm sıra aralığı uygulanan işlemlerden alınmıştır.
2- En yüksek kuru ot verimi (358.3 kg/da), ham protein verimi (52.8 kg/da) ve
ham protein oranı (% 1450) 10 kg Nida uygulanmasından elde edilmiştir.
3- Fosforun kuru ot verimine etkisi Önemli, ham protein oran ve verimine etkisi
ise önemsiz olmuştur. En yüksek kuru ot verimi (2665 kg!da) 2.5 kg P205/da
uygulanan işlemlerden alınmıştır.
THE EFFECTS OF ROW SPACING, NITROGEN AND PHOSPHORUS
ON HAY AND CRUDE PROTEİN YIELDS AND PERCENTAGE OF
CRUDE PROTEİN IN INTERMEDIATE WHEATGRASS (Agropyron
intermedium (Host.) 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/da) with three phosphorus (0,25 and 5 kg P2O5/da) 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.
1- The ejfect of row spacing was significant on protein and hay yieîds, and portein content. The highest hay yield (302.8 kg/da) was obtained with 40 cm row
spacing. The highest crude protein yield (375 kglda), and protein content (% 13.34) was obtained at 80 cm spacing.
2- The highest hay (358.3 kglda), and crude protein yields (52.8 kglda), and protein content (1450%) were detertrdned at 10 kg Nida treatment.
3- The effect of phosphorus was significant on hay yield. The highest hay yield (2665 kglda) was obtained at 2 5 kg P20ºlda treatment. No effect of phosphorus on crude protein yields and protein content of hay occured.
