    Yield and quality characteristics of sunflower silages in highlands

    Guney, Erdal; Tan, Mustafa; Yolcu, Halil

    This research was carried out to compare the yield and quality characteristics of four sunflower (Helianthus annuus L.) genotypes (i.e., confectionery Tekirdag landrace, confectionery Erzurum landrace, oilseed Sirena and oilseed C70165 hybrids) and one corn (Zea mays L.) genotype (i.e., SZE TC-S13 hybrid) in the Agriculture Faculty of Ataturk University in the east of Turkey during the period between 2005 and 2006. The study was designed in a randomized complete block design with five treatments replicated three times. The genotypes were evaluated in terms of forage properties as well as chemical and physical properties of silages in both years. According to the results, the corn genotype had better yield and silage qualities than sunflower genotypes. But crude protein contents of silages of sunflower genotypes were superior in comparison to the corn genotype. Also amongst sunflower genotypes, confectionery Tekirdag and Erzurum landraces had slightly higher silage qualities than oilseed sunflower hybrids.

    Evaluation of annual legumes and barley as sole crops and intercrop in spring frost conditions for animal feeding I. Yield and quality

    Yolcu, Halil; Dasci, Mahmut; Tan, Mustafa

    This study evaluated sole grass pea (Lathyrussativush.), sole common vetch (Vicia sativa L.), sole barley (Hordeum vulgare L.), common vetch + barley intercrop, common vetch (I) and barley (I) in terms of yields and quality properties in 2006-2007 at Kelkit Aydin Dogan Vocational Training School Research Station of Gumushane University, Turkey. Intercrop plants were separated as common vetch (called as common vetch I) and barley (called as barley I). Plants were seeded in April of both years in a randomized complete block design with 3 replications. The study plots were 3.0 m long by 1.68 m wide, with 24 cm row spacing. Each plot was fertilized with 20 ton ha-1 organic farmyard manure. The year effects were significant in dry matter yield, crude protein, crude protein yield, acid detergent fiber and neutral detergent fiber. The legumes especially were injured by frost in 2007. Significant differences were found in terms of Dry Matter Yield (DMY), Crude Protein (CP), Crude Protein Yield (CPY), Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF), Dry Matter Intake (DMI), Dry Digestible Matter (DDM) and Relative Feed Value (RFV) amongst all the plants. Sole common vetch and sole barley had good properties in DMY, CP and CPY. Sole grass pea, common vetch (I), sole common vetch and intercrops showed good quality properties in ADF and NDF. Sole grass pea especially, sole common vetch and common vetch (I) had good quality properties in DMI, DDM and RFV. Farmers should prefer sole common vetch and sole grass pea cultivation in yield and quality and regulate their seeding times according to days with frost in similiar conditions.

    This study was carried out to determine of nutrient contents of twelve lucerne cultivars in the highlands of Turkey. There were significant differences (p < 0.01) among the cultivars for crude protein (CP), neutral-detergent fiber (NDF), acid-detergent fiber (ADF). digestible dry matter (DDM), dry matter intake (DMI), relative feed value (RFV), total digestible nutrients (TDN), net energy-lactation (NEl), net energy-maintenance (NEm) and net energy-gain (NEg). Although Planet cultivar had the highest protein content (32.00 %). Kayseri cultivar is one of the lowest protein content (24.17 %) among the all cultivars. Neutral detergent fiber in cultivars ranged from 33.41 % (Seker cultivars) to 50.39 % (Kayseri cultivars). Average acid detergent fiber content for all cultivars was 34.31 %. Relative feed value in cultivars ranged from 104.78 % (Bilensoy-80 cultivars) to 185.03 % (Seker cultivars). The average TDN content was 56.89 %. Evaluating for this respect contents were the most quality Seker, Bilensoy and Savas cultivars among lucerne cultivars. In conclusion, Seker, Bilensoy and Savas cultivars among lucerne cultivars had better nutrient content than other cultivars.
