Some Agronomical and Quality Traits in Nine Vetch (Vicia ssp.) Species Cultivated in Southeastern Anatolia, Turkey

Abstract The study was performed to examine forage yield, seed yield and related parameters in nine vetch (Vicia) species. A randomized block design experiments with four replicates were carried out during the winter growing seasons of 2007–2008 and 2008–2009 at the experimental farm of the Faculty of Agriculture, Dicle University, Diyarbakir, Turkey. Over two growing seasons, we observed the following ranges of values across nine Vicia species: main stem number, 2.18–3.67; main stem thickness, 1.42–4.07 mm; plant height, 40.30– 82.16 cm; fresh forage yield, 8.46–22.73 t ha–1 ; dry matter yield, 2.39–5.23 t ha–1 ; dry matter crude protein content 13.64–19.50%, dry matter crude protein yield 0.326–0.961 t ha–1 ; number of pods per plant, 7.59– 16.03; number of seeds per pod, 2.83–6.02; 1000-seed weight, 41.91–219.9 g; seed yield, 0.74–2.84 t ha–1 ; seed crude protein content 23.29–45-73%; seed crude protein yield 0.74–2.84 t ha–1 ; biological yield, 4.26– 12.75 t ha–1 ; harvest index, 16.57–28.34%; and seed germination rate, 7.63–97.00%. Results of the study showed that Vicia narbonensis, Vicia sativa, Vicia. sericocarpa var. serico species were more productive for fresh forage yield, dry matter yield, dry matter crude protein content and dry matter crude protein yield traits. On the other hand, for seed yield and seed crude protein yield traits Vicia narbonensis was found by far as the most productive species. With very high seed crude protein content, Vicia michauxii var. stenophy was found remarkable. Key Words: Vetches (Vicia ssp.), forage yield, crude protein content, seed yield, yield components Ozet Bu arastirma, dokuz fig turunde (Vicia) ot verimi, tohum verimi ve bu verimlerle iliskili ozellikleri incelemek amaciyla ele alinmistir. Arastirmada denemeler, Dicle Universitesi Ziraat Fakultesi deneme alanlarinda, 2007-08 ve 2008-09 ekim sezonlarinda, kislik olarak, tesaduf bloklari deneme desenine gore, dort tekerrurlu olarak yurutulmustur. Iki yillik gozlem verilerine gore dokuz fig turunde incelenen ozellikler asagidaki sekilde degisim gostermistir. Ana sap sayisi, 2.18–3.67 adet; ana sap kalinligi, 1.42–4.07 mm; bitki boyu 40.30– 82.16 cm; yesil ot verimi 8.46–22.73 t ha–1 ; kuru ot verimi 2.39–5.23 t ha–1 ; kuru ottaki ham protein orani %13.64–19.50, kuru ot ham protein verimi 0.326–0.961 t ha–1 ; bitkide bakla sayisi 7.59–16.03 adet, baklada tane sayisi 2.83–6.02 adet; bin dane agirligi 41.91–219.9 g; tohum verimi 0.74–2.84 t ha–1 ; tohumdaki ham protein orani %23.29–45-73; tohum ham protein verimi 0.227-0.858 t ha–1 ; biyolojik verim 4.26–12.75 t ha–1 ; hasat indeksi %16.57–28.34 ve tohum cimlenme orani %7.63–97.00. Arastirma sonucuna gore; Vicia narbonensis, Vicia sativa, Vicia. sericocarpa var. serico. turleri yesil ot verimi, kuru ot verimi, kuru ottaki ham protein orani ve kuru ot ham protein verimi ozellikleri bakimindan daha verimli bulunurken, Vicia narbonensis turu tohum verimi ve tohum ham protein verimi ozellikleri bakimindan en verimli tur olmustur. En yuksek tohumdaki ham protein oraniyla Vicia michauxii var. stenophy turu dikkat cekici bulunmustur.
