Changes in hay yield and quality of bulbous barley at different phenological stages

Öz:
Bu çalışmanın amacı, Samsun ekolojik şartlarında 2003-2007 yılları arasında doğal floradan toplanan yumrulu arpa popülasyonunun farklı fenolojik dönemlerindeki kuru ot verimi ve kalite öğelerinin değişimini belirlemektir. Yumrulu arpanın ilkbahar-yaz (otlatma olgunluğu, erken başaklanma, başaklanma ve süt-hamur olum dönemi) ve sonbahar periyodundaki (erken gelişme) fenolojik dönemleri araştırılmıştır. Gelişme dönemlerine bağlı olarak; kuru ot verimi, nispi yem değeri, ham protein, asit ve nötral çözeltide çözünen lif, Ca, Mg, K, P, Mn, Fe ve Zn içerikleri, K(Ca + Mg$)^ {-1}$ ve Ca $P^ 1$ oranları arasında önemli farklılıklar belirlenmiştir. Bitki gelişiminin ilerlemesiyle; kuru ot verimi, asidik ve bazik ortamda çözünen lif oranı ve Ca $P^ 1$ oranı artarken, nispi yem değeri, CP, Ca, Mg, K, P, Mn, Fe ve Zn içerikleri ve K(Ca + Mg$)^ {-1}$ oranı azalmıştır. Cu içeriği ise bütün fenolojik dönemlerde değişken bir tavır göstermiştir. Araştırma sonuçları, yumrulu arpa kuru otundan en yüksek faydayı temin etmek için hasat veya otlatmanın geciktirilmemesi gerektiğini göstermiştir. Ayrıca, bütün gelişme dönemlerinde yumrulu arpa kuru otunda bazı minerallerin sağlıklı bir beslenme açısından yetersiz miktarda olduğu, diğer bazılarının ise ihtiyacın üzerinde olduğu bulunmuştur. Bundan dolayı verimli bir hayvan besleme için yumrulu arpanın ağırlıkta olduğu rasyonlara bazı minerallerin takviye edilmesi ya da yumrulu arpa ile baklagil yem bitkilerinin karışımlar halinde yetiştirilmesi gerekmektedir.

The objective of this study was to determine the changes in hay yield and quality components at different phenological stages of a bulbous barley (Hordeum bulbosum L.) population handpicked from natural flora during 2003- 2007 in Samsun, Turkey. The phenological stages of bulbous barley during spring-summer (grazing maturity, early heading, heading, and milk-dough) and autumn (early growing) were investigated. Significant differences were observed in hay yield, relative feed value (RFV), crude protein (CP), acid and neutral detergent fiber (ADF and NDF), Ca, Mg, K, P, Mn, Fe, and Zn concentrations, and K(Ca + Mg$)^ {-1}$ and Ca $P^ 1$ ratios of DM, depending on development stages. Hay yield, ADF, NDF concentrations, and the Ca $P^ 1$ ratio increased, whereas RFV, CP, Ca, Mg, K, P, Mn, Fe, and Zn concentrations, and the K (Ca + Mg$)^ {-1}$ ratio in DM decreased as plant development progressed. The Cu concentration was inconsistent at all phenological stages. The results of this research indicate that harvesting or grazing should not be delayed in order to obtain the maximum benefit of bulbous barley hay. Additionally, while some minerals were inadequate, others were in excess, in terms of healthy feeding, at all development stages. Therefore, additional supplementation with some minerals is needed for bulbous barley-based ration or bulbous barley should be grown in mixtures with legumes for feeding productive livestock.
