Abstract

Silaj karışımındaki çim yapısı ve N gübrelemesinin silaj kalitesine etkisi 2 yıllık bir çalışma ile araştırılmıştır. Çalışmada monokültür olarak adi yonca Medicago sativa ve karıım olarak da kamışsı yumak Festuca arundinacea domuz ayrığı Dactylis glomerata ve korunga Onobrychis sativa bulundurulmuştur. Azotlu gübre 0, 70, 140 ve 210 kg ha-1dozlarında uygulanmıştır. Yüksek düzeyde amonyak azotu NH-N , asetik asit AA , butirik asit BA ve daha düşük laktik asit LA içeriği nedeniyle adi yonca silajının kalitesi, adi yonca ile çim karışımı silajlarından düşük olmuştur. Artan miktarda N uygulamaları NH3-N, AA ve BA miktarında önemli düzeyde artışa LA miktarında ise önemli düzeyde azalışa neden olmuştur

The Effect of Sward Structure and N Fertilization on the Grass-legume Silage Quality

Abstract

The effect of sward structure of the mixtures and nitrogen fertilization on grass-legume silage quality was investigated over two years. The study included Lucerne Medicago sativa in monoculture and in mixtures with cocksfoot Dactylis glomerata , tall fescue Festuca arundinacea and sainfoin Onobrychis sativa . Nitrogen fertilizer was applied to the field plots at four different rates: 0, 70, 140 and 210 kg ha-1. The quality of lucerne silage was inferior to lucerne silage mixed with grasses due to the greater content of ammonia nitrogen NH3-N , acetic AA and butyric acids BA , and reduced content of the lactic acid LA . Gradual increase of N fertilization significantly has increased the content of NH3-N, AA and BA and decreased the content of LA
