Abstract
The present study was conducted to determine the herbage yield, nutrient contents and optimum harvesting date of pastures in Kars district. Herbage samples were harvested from pastures on June 22, July 2, 12 and 21. Fresh herbage yields were found to be 723, 829, 824 and 599 kg/da, while dry matter yields were 193, 218, 231 and 185 kg/da, respectively, according to the harvesting date. It was found that, depending on the progression ofharvesting date, organic matter (90.71, 91.41, 91.02 and 91.61%), crude ash (9.29, 8.59, 8.98 and 8.39%), ether extract (2.63, 2.69, 3.01 and 3.03%) and nitrogen-free extract (43.98, 46.16, 45.57 and 46.79%) were not changed significantly, while crude protein (13.94, 11.67, 10.48 and 9.14%) decreased significantly (P
Özet
Bu çalışma, Kars yöresindeki çayırların verim özelliklerinin, besin madde içeriklerinin ve en uygun biçim tarihinin belirlenmesi amacıyla yapılmıştır. Çayırlardan 22 Haziran, 2, 12 ve 21 Temmuz’da ot örnekleri alınmıştır. Biçim tarihlerine göre yaş ot verimi; 723, 829, 824 ve 599 kg/da, kuru madde verimi; 196, 235, 250 ve 205 kg/da olarak bulunmuştur. Biçim tarihlerinin ilerlemesine bağlı olarak, otların organik madde (%90.71, 91.41, 91.02 ve 91.61), ham kül (%9.29, 8.59, 8.98 ve 8.39), ham yağ (%2.63, 2.69, 3.01 ve 3.03) ve azotsuz öz madde (%43.98, 46.16, 45.57 ve 46.79) içeriklerinin değişmediği, ham proteinin (%13.94, 11.67, 10.48 ve 9.14) azaldığı (P
