Kırşehir Ekolojik Koşullarında Bazı Silajlık Sorgum ile Sorgum-Sudanotu Melez Çeşitlerinin Verim ve Kalite Özelliklerinin Belirlenmesi

Bu araştırma Kırşehir ilinde 2016-2017 yaz yetiştirme sezonunda bazı sorgum ve sorgum-sudanotu melez çeşitlerinin verim ve kalite özelliklerini belirlemek amacıyla tek lokasyonda yürütülmüştür. Bölünmüş parseller deneme desenine göre üç tekerrürlü olarak yürütülen bu çalışmada, üç sorgum (Gözde 80, Early Sumac, Rox) ve altı sorgum-sudanotu (Aneto, Greengo, Teide, Sugar Graze, Gardavan, Jumbo) melez çeşidi kullanılmıştır. Denemeye alınan sorgum ve sorgum-sudanotu melez çeşitleri arasında özellikler bakımından önemli derecede farklılıkların olduğu belirlenmiştir. İki yıllık ortalama sonuçlara göre; çeşitlerin kuru madde verimleri 1185.3 (Gözde 80) – 28957.3 (Jumbo) kg ha-1, ham protein verimleri 8777.5 (Gözde 80) ve 2799.8 (Jumbo) kg ha-1 ve sindirilebilir kuru madde verimleri 7396.5 (Gözde 80) ve17908.3 (Jumbo) kg ha-1. Protein oranı % 7.3 (Gözde 80) - 10.4 (Aneto), ADF oranı % 30.1 (Rox) - 37.4 (Early Sumac), NDF % 44.6 (Rox)- 57.2 (Early Sumac), ADL % 4.2 (Early Sumac) - 5.6 (Teide ) SKMO % 59.7 (Early Sumac) - 65.5 (Rox) arasında değişmiştir. Kırşehir ekolojik koşullarında verim ve kalite bakımdan Jumbo çeşidi ile Greengo çeşidi alternatif bir yem bitkisi olarak yetiştirilebileceği belirlenmiştir.

Yield and Quality Feature of Some Silage Sorghum and Sorghum-Sudangrass Hybrid Cultivars in Ecological Conditions of Kırşehir Province

This current study was conducted to determine adaption and quality characters of sorghum and sorghum-sudangrass hybrid during 2016-2017 summer growing seasons in Kırşehir province. The experimental was a randomized complete block design with three replications, three sorghum cultivars (Gözde 80, Early Sumac, Rox) and six sorghum-sudangrass (Aneto, Greengo, Teide, Sugar Graze, Gardavan, Jumbo) hybrid cultivars. There were significant differences in tested characters among sorghum and sorghum-sudangrass hybrid cultivars. According to average two years; dry matter yield of the cultivars was between 11855.3 (Gözde 80) and 28957.3 (Jumbo) kg ha-1, crude protein yield was between 877.5 (Gözde 80) and 2799.8 (Jumbo) kg ha-1 and digestible dry matter yield was between 7396.5 (Gözde 80) and 17908.3 (Jumbo) kg ha-1. Crude protein ratio ranged from 7.3 (Gözde 80) to 10.4 (Aneto) %, ADF from 30.1 (Rox) to 37.4 (Early Sumac) %, NDF from 44.6 (Rox) to 57.2 (Early Sumac) %, ADL from 4.2 (Early Sumac) to 5.6 (Teide ) % and digestible dry matter from 59.7 (Early Sumac) to 65.5 (Rox) %. To conclude; Greengo and Jumbo that had better results among the studied cultivars, are suggested as alternative forage crops in Kırşehir ecological condition.
