Doğu Akdeniz koşullarında ikinci ürün olarak yetiştirilen bazı hibrit mısır genotiplerinde tane ve yem verimi ile yem kalite özelliklerinin değerlendirilmesi

Abstract

This research was conducted in order to guide farmers and researchers by determining grain, forage yield and yield-related traits and forage quality of different parts of the whole plant in some maize cultivars in Eastern Mediterranean ecological conditions. In this study, it was assessed grain and forage yield and fodder quality of four maize cultivars (PR91G98, SY Castaneda, SY Gladius, and SY Tuscani) cultivated under the Estern Mediterranean conditions. To determine forage quality, ear, stem and leaves of the whole plant maize were analyzed separately. To evaluate grain and forage yield, parameters like plant height, stem diameter, hay yield, dry matter yield, green leaf yield, green stem yield, ear weight, green ear yield were investigated while features such as crude protein, crude ash, organic matter, NDF, ADF, digestibility of dry matter, dry matter intake and relative feed value were examined to determine forage quality. The new maize cultivars have been updated continually; it is important to clarify the responses of new varieties to agronomic practices and forage yield, quality, grain yield, and related traits. The results of this study revealed that ear is very important for forage yield and quality. The greatest hay and grain yield were produced by PR31G98 maize cultivar. It was observed SY Tuscani had higher NDF and ADF values than other maize varieties. With this study, the importance of nutrient content according to silage yield and plant parts in second crop corn cultivation was determined. In addition, research results showed important source data for farmers and researchers regarding forage and grain yield of maize farming and production area is continually increasing.
