Özet
Amaç: Bu çalışma, horozibiği (Amarantus mantegazzianus) bitkisinde farklı azot ve fosfor seviyelerinin ot verimi ve bazı silaj kalite özelliklerine etkisini saptamak amacıyla yürütülmüştür. Materyal ve Metot: Araştırma, 2016 yılı yaz yetişme döneminde, Ege Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü, İzmir, Türkiye’de dış ortam koşullarında saksı denemesi olarak gerçekleştirilmiştir. Denemede, horozibiği bitkisinin Don Juan genotipi kullanılmış ve üç farklı fosfor (0, 5, 10 kg P/da) ile beş değişik azot (0, 5, 10, 15, 20 kg N/da) dozu uygulanmıştır. Çalışmada, bitki boyu, yaprak sayısı, doğal kuru madde (KM) oranı, yaş ot ve kuru madde verimi, silaj pH’sı, silaj ham protein oranı, NDF ve ADF oranları incelenmiştir. Bulgular ve Sonuç: Sonuçlar; artan azot ve fosfor seviyelerinin kontrol uygulamasına göre verim ve silaj kalitesine olumlu yönde etki ettiği belirlenmiştir. Horozibiğinde en yüksek KM verimi ve kabul edilebilir silaj yemi kalitesi dekara 15 kg N ve 10 kg P uygulamasında sağlanmıştır.
Objective: This study was conducted to determine the effect of different nitrogen and phosphorus levels on the herbage yield and some silage quality parameters of amaranth (Amarantus mantegazzianus). Material and Methods: The experiment was carried out at Ege University, Faculty of Agriculture, Department of Field Crops, Izmir, Turkey, during the summer growth seasons of 2016 as a pot experiment grown under outdoor. In the experiment, Don Juan genotype of amaranth was used as crop material and three levels of phosphorus (0, 50, 100 kg P ha-1) and five levels nitrogen were tested. Some traits tested in the experiment were plant height, fresh and dry matter (DM) yield, silage pH, crude protein content of silage, NDF and ADF contents. Results and Conclusion: Results indicated that increasing N and P levels affected positively above mentioned traits compared to the control. The highest DM yield and acceptable silage quality for amaranth were obtained from 150 kg N and 100 kg P application per hectare.
