Investigations on the green matter and grain yield of some corn cultivars grown as second crop under Mardin ecological condinations

This study was conducted to determine delivery and some agricultural attributions about delivery of six different corn variety as a propose of silage and piece delivery at the farmer's field of Artuklu in Mardin conditions in 2013. The experiment was designed as triplicate and viable to randomized complete block method and corn variety those raises widespread in our locality were used. Statistical differences were found among delivery and delivery attribution of corn variety. in varieties development delivery; rate of dry matter differ between 24,3% - 28,8% , while delivery of dry matter differ between 929-1699 kg/da and development delivery differ between 3484-6143 kg/da on the other hand varieties piece delivery between 831-1120 kg/da and piece gravity differ between 348,0-489,0 g for a thousand pieces. Among varieties used in experiment, the best varieties for development delivery were Pioneer M15 and the best varieties for piece delivery were Dekalp 6120, Helen and NK Famoso.
