Özet


This study was conducted to determine the residue effects of chicken manure on the yield and yield components of eight onion varieties as second crop after lettuce in field condition. Varieties (14-16, Burgaz, Karbeyazı, Naz, NWG, Perwana, Seyhan, Şampiyon) and also four different doses of chicken manure at the rates of 0, 20, 40, 60 t ha-1 with the recommended dose of NPK were used. A non-fertilized parcel was used as control. The experiment was laid out in split plot design and replicated three times. Yield and yield components were investigated. According to the results residual effect of chicken manures and onion varieties as second crop significantly affected the yield and bulb production in the field condition. The application of chicken manure significantly improved yield, bulb weight, bulb height, number of shoot tip, number of dried leaf compared to control. Highest yields (46.31 t ha-1 ) were obtained in the parcels where the chicken manure was applied at a rate of 60 t ha-1 . The onion cultivar Burgaz was more responsive to the chicken manure compared to other onion cultivars. The best yield was shown by the Burgaz cultiva
