Bitkiler için en önemli besin elementlerinden biri azot olup atmosferik azotun organik forma dönüştürülmesinde bazı bitkiler görev almaktadır. Köklerinde bulunan bakteriler vasıtasıyla azot bağlama yeteneğinde olan bu bitkiler azot eksikliğinin hafifletilmesi ve toprağın iyileştirilmesi bakımından önem arz etmektedir. Araştırmada azot bağlayıcı bazı türlerle birlikte yetiştirilen sarıçam (Pinus sylvestris L.) fidanlarındaki gelişim farklılıklarının ortaya koyulması amaçlanmıştır. Bu çalışma Karadeniz Teknik Üniversitesi Orman Fakültesi Araştırma ve Uygulama serasında yürütülmüştür. Alnus glutinosa, Robinia pseudoacacia ve Vicia sativa türleri azot bağlayıcı tür olarak seçilmiştir. Tohumlar Kasım ayında özel ekim kasalarına farklı ekim kombinasyonlarıyla ekilmiştir. İlk vejetasyon dönemi sonrasında bir yaşındaki sarıçam fidanlarında, fidan boyu, kök boğaz çapı ve gürbüzlük indisi değerleri belirlenmiştir. Pinus sylvestris işlemine ait fidanların ortalama boyu 3.36 cm iken, Pinus sylvestris+Vicia sativa ekim kombinasyonuna ait fidanların ortalama boyunun 6.84 cm’ye ulaştığı tespit edilmiştir. Aynı şekilde kök boğaz çapı bakımından da Pinus sylvestris+Vicia sativa ekim kombinasyonunda 0.47 mm’lik bir artış meydana geldiği görülmektedir. Özellikle diri örtü probleminin olduğu ya da rakım, iklim ve toprak özellikleri bakımından ekstrem koşullar nedeniyle kaliteli fidanların kullanılması gereken alanlarda Pinus sylvestris+Vicia sativa ekim kombinasyonu ile elde edilecek daha kaliteli fidanları kullanmak önemli bir avantaj olabilecektir.

Nitrogen is one of the most important nutrients for plants, and some plants are involved in the conversion of atmospheric nitrogen to organic form. These plants are capable of nitrogen fixing by bacteria in their roots and are important in alleviating nitrogen deficiency and improving soil. The objective of this research is to determine the growth differences in Scotch pine (Pinus sylvestris L.) seedlings grown together with some nitrogen-fixing species. The study was conducted in The Research and Application Greenhouse at Faculty of Forestry, Karadeniz Technical University. Alnus glutinosa, Robinia pseudoacacia and Vicia sativa were selected as nitrogen-fixing species. Seeds were sown, by different sowing combinations, in special sowing crates in November. For 1-year-old scotch pine seedlings after the first growing period, seedling length, root collar diameter and sturdiness quotient were determined. The results indicated that while the average length of Pinus sylvestris seedlings sown alone was 3.36 cm, the average length of the seedlings belonging to Pinus sylvestris+Vicia sativa combination reached 6.84 cm. Similarly, mean root collar diameter was 0.47 mm greater in the Pinus sylvestris+Vicia sativa sowing combination. The use of higher quality seedlings obtained through sowing combination of Pinus sylvestris+Vicia sativa can be advantageous in areas where there is a ground cover problem or the use of quality seedlings is required because of extreme conditions in terms of altitude, climate and soil.
