Özet

 This study was conducted to determine the residual effects of chicken manure on the yield and yield performance of eight onion varieties as second crops after lettuce under greenhouse condition. 14-16, Burgaz, Karbeyazı, Naz, NWG, Perwana, Seyhan, Şampiyon varieties 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 nonfertilized 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 manure and onion varieties as second crop significantly affected the yield and bulb production in the greenhouse 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 (72.99 t ha-1) were obtained in the parcels where the chicken manure was applied at a rate of 20 t ha-1. The onion cultivar Burgaz was more responsive to the chicken manure compared to other onion cultivars. The best yield was shown of Burgaz cultivar and the 20 t ha-1 chicken manure treatments by the interaction. As a result, this method is the most suitable for onion production.
