Özet:

 Objective: The current study investigated the impact of different N doses on growth traits of some sunflower Helianthus annuus L. cultivars grown as second crop. Materials and Methods: The experiment was conducted according to randomized complete block design with split-plot arrangements and three replications. Three sunflower cultivars Bosfora, P64LE119, and LG5582 and four N doses 0, 50, 100, 150, 200 kg ha-1 pure N were included in the study and data relating to different growth traits were recorded. Results: The results revealed that individual effects of cultivars and N doses exerted significant impacts on the studied growth traits, whereas their interactive effects were significant for some of the studied parameters. The earliest emergence duration was recorded under 150 and 200 kg ha-1 N. Similarly, the earliest head formation, flowering initiation and seed filling duration were recorded for Bosfora cultivar with 200 kg ha-1 N. Conclusion: The earliest physiological maturity was recorded for P64LE119 cultivar, whereas the widest head diameter and the highest head weight was noted for LG5582 cultivar under 200 kg ha-1 N application. Overall, Bosfora cultivar under 200 kg ha-1 N application performed better for head formation, flowering initiation, and seed filling duration, whereas cultivar LG5582 under 200 kg ha-1 N application performed better for head diameter and head weight.It is recommended that cultivars Bosfora and LG5582 should be provided 200 kg ha-1 N for better growth in southeastern Anatolia.

 Amaç: Bu çalışmada ikinci ürün koşullarında farklı azot dozlarının bazı ayçiçeği Helianthus annuus L. çeşitlerinde büyüme parametrelerine etkisini araştırmak amacıyla yürütülmüştür. Materyal ve Yöntem: Çalışma tesadüf bloklarında bölünmüş parseller deneme desenine yürütülmüştür. Ayçiçeği çeşitleri Bosfora, P64LE119 ve LG5582 ana parselleri, azot dozları 0, 5, 10, 15, 20 kg da-1 ise alt parselleri oluşturmuştur. Araştırma Bulguları: Çalışmada; denemeye alınan ayçiçeği çeşitlerinin incelenen özelliklerinden, en erken çıkış gün sayısı 15 ve 20 kg da-1 N dozlarından, en erken tabla oluşum başlangıcı, çiçeklenme süresi ve tane dolumu gün sayısı Bosfora çeşidinden ve 20 kg da-1 N dozundan, en erken fizyolojik olum P64LE119 çeşidinden, en geniş tabla çapı ve en fazla tabla ağırlığı LG5582 çeşidinden ve 20 kg da-1 N dozundan elde edilmiştir. Sonuç: Bu çalışma sonucunda; tabla oluşum başlangıcı, çiçeklenme süresi ve tane dolumu gün sayısı bakımından Bosfora çeşidi ve 20 kg da-1 azot dozu, tabla çapı ve tabla ağırlığı bakımından LG5582 çeşidi ve 20 kg da-1 N dozu en iyi sonucu vermiştir. Güneydoğu Anadolu Bölgesi için Bosfora ve LG5582 çeşitleri ve 20 kg da-1 N verilmesi önerilmektedir.
