Abstract:To investigate the effect of seed origin on the nutritive value of narrowleaf birdsfoot trefoil (NBT, Lotus tenuis Waldst.&Kit.), seeds of 86 NBT populations were collected from plants spontaneously occurring in natural pastures and rangelands located at different geographical gradients of the Black Sea Region, Turkey. Some nutrient contents of these populations regrown under the same conditions were determined. Minimum and maximum values with regard to the crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), Ca, P, Mg, K and condensed tannin contents, relative feed value, Ca P -1 and K (Ca+Mg) , latitudes (digestible dry matter and ADF) and longitudes (CP and Mg) on some nutrient contents and feed values were found significant (P<0.05). The correlations between altitude and NDF, P and Mg or between latitude and P and Mg contents of populations were significant. There were no specific trends in chemical composition and the nutritive value of tested NBT populations due to geographical variation. Thus, the results suggested that all studied geographical populations can be selected to obtain the nutritionally superior forage.-
Bu çalışmada, Akdeniz ikliminin sulanan koşullarında, kışlık ara ürün olarak yetiştirilebilecek dört biryıllık çim (Lolium multiflorum L.) çeşidinin yem üretim potansiyelleri araştırılmıştır. Deneme tesadüf blokları deneme desenine göre 3 tekerrürlü olarak 2019-2020 ve 2020-2021 yetiştirme sezonlarında yürütülmüştür. Bitki boyu, yeşil ot verimi, kuru ot verimi, ADF, NDF, ham protein oranı, ham protein verimi, sindirilebilir kuru madde oranı, sindirilebilir kuru madde verimi ve nispi yem değeri bakımından çeşitler arasında önemli farklılıklar saptanmıştır. Elde edilen sonuçlar doğrultusunda, Akdeniz iklimi koşullarında Teanna ve Alberto çeşitlerinin yüksek verim ve orta düzeyde ot kaliteleri ile başarılı bir şekilde yetiştirilebileceği sonucuna varılmıştır.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
