Effect of Sowing Methods on Silage Yield and Quality of Some Corn Cultivars Grown in Second Crop Season under Irrigated Condition of Central Anatolia,

摘要

Silage corn has an important potential as second crop under irrigated lands of semi-arid regions. This researchwas conducted to determine silage yield and quality of some corn cultivars (Ada, Cadiz, Donana, Sagunto andSakarya) grown after barley harvest using different sowing methods (direct and conventional) in 2014 and2015 years in Eskisehir Plain. Investigated parameters were significantly different between years except forleaf ratio and neutral detergent fiber (NDF) content. In the first year, plant height, fresh forage yield, andFleig point were higher than the second year but dry matter, crude protein, acid detergent fiber (ADF)content, cob ratio and pH were contrarily higher in the second year. Sowing method significantly affected allparameters except leaf ratio. Using direct sowing method increased cob ratio (40.3 %), dry matter (22.93 %),crude protein content (7.56 %), pH (3,76) and Fleig score (85.82) compared to conventional sowing method.Cultivars significantly varied in terms of plant height, cob ratio, dry matter, crude protein, neutral detergentfiber, acid detergent fiber, pH, and Fleig point. Considering the total silage yield and quality the domesticcultivar Ada, which seeds are common in the market, could be suggested after barley harvest for second cropproduction as long as sown conventionally in irrigated lands of Central Anatolia.
