Determination of possibilities to grow some corn (Zea mays L.) cultivars for silage production under Middle Kizilirmak Basin ecological conditions

This study was conducted, during the 2012 and 2013 corn growing seasons, for a period 2 years, according to the randomized complete block design, as 3 replicates, at the research and implementation area of the kizilirmak vocational high school of cankiri karatekin university (40°20ꞌ n, 33°58ꞌ e, elevation 550 m), which is located on the middle kizilirmak basin of turkey. in this study, 20 different corn varieties used silage were used as a plant material. according to mean of 2 years, significant differences have been determined among the all properties as statistically. the highest corncob number (1.9 item plant-1) in the nk arma and corncob ratewere arranged in the nk famoso (50.1%) and the sakarya (49.5%) varieties. while the superior herbage yields were obtained in the carella (131.900 kg ha-1), kompozit arifiye (128.300 kg ha-1), cadiz (126.600 kg ha-1), andlarigal (123.600 kg ha-1) varieties, dry matter yields were determined in the donana (416.300 kg ha-1), larigal (414.500 kg ha-1), and cadiz (409.800 kg ha-1) varieties. the best results were stated from the nk arma (2575 kg ha-1), larigal (2523 kg ha-1), and cadiz (2495 kg ha-1) varieties as crude protein yield. in conclusion, the carella, larigal, cadiz, kompozit arifiye, and nk arma varieties can be suggested compared with the other varieties under middle kizilirmak basin ecological conditions.
