Evaluation of Silage Corn Hybrids as Second Cropping

In this study, ten varieties and varieties-to-be of hybrid maize (BT-M-12 x BT. M-B, BT-M-30 x BT. M-B, BT-M-46 x BT. M-B, BT-M-71 x BT. M-B, BT-M-124 x BT. M-B, BT-M-149 x BT. M-B, BT-M-159 x BT. M-B, OSSK-644, Ari-fiye and MAT-97) were grown as second crop in the 2005 growing season in the ecological conditions of Antalya. The experiment was designed with “Random-ized Complete Blocks Designed” with four replications. In the research, plant height, leaves per plant, stem diameter, leaf / stem ratio, leaf ratio, flowering pe-riod, vegetation period, forage yield, dry matter ratio, dry matter yield, protein ratio and crude protein yield were determined. According to the results, green forage yields of hybrid maize varieties were 77.7 t/ha (BT-M-71 x BT.M-B) – 133.0 t/ha (BT-M-159 x BT.M-B), dry matter ratio were 18.99 % (BT-M-12 x BT.M-B) - 20.93 % (OSSK 644), dry matter yield were 15.0 t/ha (BT-M-71 x BT.MB) – 26.9 t/ha (BT-M-159 x BT.M-B), crude protein rates were 2.36 % (MAT-97) - 2.76 % (BT-M-71 x BT.M-B), and crude protein yields were 2.1 t/ha (BT-M-71 x BT.M-B) – 3.2 t/ha (BT-M-159 x BT.M-B) respectively. This re-search suggests that “BT-M-159 x BT.M-B” can be grown as second crop under the ecological conditions in Antalya.
