Abstract

This study was conducted in 2023 and 2024 to reveal the differences in yield, quality, and nutrient content of meadows in Bingöl province (Türkiye) semi-arid ecological conditions according to different cutting times. In the study, meadows were harvested at 15-day intervals starting in May and four cuttings were performed. Yield characteristics included green forage yield and dry matter yield; quality characteristics included crude protein content, crude protein yield, acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM), and relative feed value (RFV); and nutrient elements included phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg) were examined. The second and third cutting times were superior in terms of dry matter yield and crude protein yield, and the first cutting time had the highest values for crude protein, ADF, NDF, DDM, RFV, P and K contents. No statistically significant differences were detected between cutting times in terms of Ca and Mg contents. It was observed that the ground water was high in the first and second cutting times and the possibility of machine harvesting was very low in the meadow areas examined. Therefore, although the first and second cutting times gave high values in terms of quality characteristics, it is not recommended to harvest at these times. In addition, since meadow areas are generally used for dry matter production, it was concluded that the third cutting time, when dry matter yield and crude protein yield are high, should be preferred instead of the first cutting time when quality characteristics are high. Accordingly, it has been concluded that harvesting meadow areas in early June is more advantageous in semi-arid transition zones and regions with similar ecological conditions.

Özet

Bu çalışma, Bingöl ili (Türkiye) yarı-kurak ekolojik koşullarında, farklı biçim zamanlarına göre çayırların verim, kalite ve besin elementleri içerikleri açısından gösterdiği farklılıkları ortaya koymak amacıyla 2023 ve 2024 yıllarında yürütülmüştür. Araştırmada mayıs ayından başlamak üzere 15 günlük aralıklar ile 4 biçim zamanı olacak şekilde çayır alanlarında hasat yapılmıştır. Verim özelliklerinden yeşil ot verimi ve kuru ot verimi, kalite özelliklerinden ham protein oranı, ham protein verimi, asit deterjanda çözünmeyen lif (ADF), nötr deterjanda çözünmeyen lif (NDF), sindirilebilir kuru madde (SKM) ve nispi yem değeri (NYD), besin elementlerinden de fosfor (P), potasyum (K), kalsiyum (Ca) ve magnezyum (Mg) içerikleri incelenmiştir. Kuru ot verimi ve ham protein verimi açısından ikinci ve üçüncü biçim zamanları, ham protein, ADF, NDF, SKM, NYD, P ve K içerikleri açısından ise birinci biçim zamanları ön plana çıkmıştır. Ca ve Mg oranları açısından biçim zamanları arasında istatistiksel olarak herhangi bir farklılık tespit edilmemiştir. İncelenen çayır alanlarında birinci ve ikinci biçim zamanlarında taban suyunun yüksek olduğu ve makineli hasat yapma imkanının oldukça düşük olduğu görülmüştür. Bu nedenle her ne kadar birinci ve ikinci biçim zamanları, kalite özellikleri açısından yüksek değerler vermiş olsa da bu zamanlarında hasat yapılması tavsiye edilmemektedir. Ayrıca genel olarak çayır alanları kuru ot elde etmek için değerlendirilen alanlar olduğundan, kalite özelliklerinin yüksek olduğu birinci biçim zamanı yerine, kuru ot verimi ile ham protein veriminin yüksek olduğu üçüncü biçim zamanının tercih edilmesi gerektiği kanaatine varılmıştır. Dolayısıyla yarı kurak geçiş bölgelerinde ve benzeri ekolojik koşullara sahip bölgelerde, çayır alanlarında hasat işleminin haziran ayının başında yapılmasının daha avantajlı olduğu sonucuna varılmıştır.
