Bu çalışma, 2019 ve 2020 vejetasyon döneminde Bilecik ekolojik koşullarında yem şalgamı “YŞ” ile farklı tahıl “T” (arpa, “A”, buğday “B” ve yulaf “Y”) karışımlarının yeşil ot verimi ve rekabet oranlarının belirlenmesi amacıyla yürütülmüştür. Bitkiler yalın ve 3 farklı karışım (75YŞ+%25T 50FT+%50C ve 25FT+%75C) oranında ekilmiştir. Çalışma Tesadüf Blokları Deneme Desenine göre üç tekerrürlü olarak kurulmuştur. Çalışmada yeşil ot verimi, alan eşdeğerlik oranı (LER), rekabet indeksi (Rİ), agresivite (A) ve gerçek verim kaybı (GVK) değerleri belirlenmiştir. Yeşil ot verimi 23.91 ile 43.24 t ha-1 arasında değişmiştir. AEO en yüksek 50YŞ+%50Y (1.43), en düşük ise 75YŞ+%25B (0.94) karışımında olmuştur. Tahılların rekabet oranlarının yem şalgamına göre daha yüksek olduğu belirlenmiştir. Ayrıca karışımlarda tahıl oranı arttıkça GVK azalmıştır.
Sonuç olarak, yem şalgamına tahıl ilavesinin yeşil ot verimini arttırdığı ve karışımların yalın ekimlere göre daha iyi performans gösterdiği belirlenmiştir. Ayrıca tüm özelliklere göre Bilecik ekolojik koşullarında arpa ve yulafın yemlik şalgam ile %50+50 ve %25+75 tohum oranında ekiminin uygun olduğu sonucuna varılmıştır.

Competition Indices of Forage Turnip Cereal Intercrops in Different Seeding Ratio

Öz

The aim of current study was to determine of intercropping forage turnip “FT” with cereals “C” (barley, “B”, wheat “W” and oat “O”) for herbage yield and competitive ratios in Bilecik conditions in 2019-2002 and 2020-2021 growing periods. Plants were sown as sole and in 3 different mixtures (75FT+25C%, 50FT+50C% and 25FT+75C %). Experiments were arranged in a randomized complete block design with three replications. In the study, herbage yield, land equivalent ratio (LER), competitive ratio (CR), aggressivity (A), and actual yield loss (AYL) values were determined. The herbage yield was ranged from 23.91 to 43.24 t ha-1.The highest LER value 50FT+50O% (1.43), while the lowest was in 75FT+25W% (0.94) mixture. It has been determined that the competitive ratios of cereals are higher than forage turnip. Besides, the AYL decreased with the increase in cereals ratio in mixtures.
As a result, it was determined that the addition of cereal to the forage turnip increased the herbage yield and the mixtures performed better than the monocrops. Besides, according to the all traits, it was concluded that it would be appropriate to sown forage turnip with barley and oats at a seed rate of 50+50% and 25+75% in Bilecik ecological conditions.
