    Determination of High Yield and Quality Sainfoin Genotypes (Onobrychis viciifolia Scop.) for the Bingöl Province of Turkey
    (2023) Çaçan, Erdal; Kökten, Kağan; Koç, Ali
    This research was carried out for two years between 2017-2018 to determine the high yield and quality sainfoin genotypes for Bingöl Province. A total of 13 genotypes were used as plant materials, two of which were registered cultivars (Lutfibey, Peschanyj 1251), six candidate cultivars (Emre, Hilal, Fatih, Mehmetalibey, Koc 1461, Yunus) and five were populations (Genc, Adakli, Yedisu, Ankara, Tarim). In the study forage yields, dry matter yields, crude protein ratios, crude protein yields, ADF (acid detergent fiber) ratios, NDF (neutral detergent fiber) ratios, digestible dry matter ratios and relative feed values of genotypes were investigated. As the average of two years of the genotypes; the forage yield was 1832±60 kg da-1, the dry matter yield was 576±20 kg da-1, the crude protein rate was 16.4±0.3%, the crude protein yield was 95.3±3.9 kg da-1, the ADF rate was 31.2±0.5%, the NDF rate was 43.8±0.6%, the digestible dry matter rate was 64.6±0.4% and the relative feed value was obtained as 139±2.3. According to two years data in the study, the differences between genotypes were found statistically significant (p<0.01) in terms of forage yield, dry matter yield and crude protein yield, but the differences between genotypes were found to be statistically insignificant in terms of crude protein, ADF, NDF and digestible dry matter ratios and relative feed value. As a result, it was determined that Tarim, Hilal, Peschanyj and Lutfibey genotypes came to the fore in the conditions of Bingöl Province in terms of the examined characteristics.

    Growing Forage Pea (Pisum arvense L.) for Hay: Different Sowing Dates and Plant Densities in Central Anatolia
    (2023) Sarıkaya, Meliha Feryal; İleri, Onur; Erkovan, Şule; Erkovan, Halil İbrahim; Koç, Ali
    The study was carried out to determine the effects of different sowing times (October and November) and plant densities (80, 100, and 120 seeds m ?2) on hay yield and quality of some forage pea cultivars (Özkaynak and Taşkent) in 2018 and 2019 years of Eskisehir ecological condi- tions. The experiment was established in Randomized Complete Block Design with three replica- tions. Hay yield, crude protein, neutral detergent fiber, acid detergent fiber, and acid detergent lignin contents were investigated. Hay yield, acid detergent fiber, and acid detergent lignin con- tents were higher in 2018 (5139.2 kg ha ?1, 31.76%, and 8.02%, respectively) but crude protein (13.89–14.44%) and neutral detergent fiber (37.52–37.77%) contents did not change significantly between the years. Cultivars and plant densities did not cause any significant variation on the examined characteristics but late autumn sowing caused a 1.51% increase in crude protein con- tent, which was significant. Neither late autumn sowing nor different plant densities caused any negative effects on hay yield and quality of forage peas. Therefore, forage peas could be sown in both October and November using any of the Özkaynak or Taşkent cultivars at 80 seeds m?2 plant density in Central Anatolia conditions.
