Determination of Yield and Yield Components Of Some Silage Corn (Zea mays L.) Varieties Under Diyarbakır Ecological Conditions

This investigation was conducted to determine yield and yield components of some silage corn varieties that are suitable for Diyarbakir ecological conditions experienced at GAP international Agricultural Research Training Center experiment area in the main growing season 2015. The experimental design was randomised in a complete block design with three replications. Varieties Burak, Samada 07, TK 6063, OSSK 644, Bolson and Hido were used as plant material in present study. The range height of the plants used in the research was 263.33 – 314.66 cm, the range of ratio of stem plant was 41.93-58.50 %, leaf plant was 18.20 – 22.17 %, cob / plant was 20.37 – 38.50 %. The range of green herbage yield was 5694.85 – 10820.85 kg, hay yield 1431.00 – 3006.33 kg, cop weight 220.00 – 317.33 gr /plant. The range of crude protein was 4.09 – 6.27 %, crude protein yield was 79.70 – 125.93 kg, silage pH 3.67 – 3.90, ADF (Acid detergent fiber) 30.40 – 35.97 %, NDF (Neutral detergent fiber) 52.90 – 60.20 %. As a result of the investigation it has been found that Burak, TK6063, Samada 07 and Bolson were the best suitable plants compaire to quality of the silage and green herbage.
