In this study, the effects of fall nitrogen fertilization on nitrogen concentration and early height growth

after planting with quality of two year old Anatolian black pine (Pinus nigra ssp. nigra Arn. var. caramanica

(Loudon) Rehder) seedlings were investigated. Bareroot Anatolian black pine seedlings in Eğirdir Forest

Nursery were fertilized with ammonium sulfate [(NH4)2SO4] at 0, 5, 10 and 20 N g/m² between September 28

and October 18. Seedling morphological characteristics and needle nitrogen concentration were determined one

week after fertilization (October 2009) and before planting (March 2010). Seedlings were planted in the field in

early march and evaluated early height growth and needle nitrogen concentration two months after planting.

According to results, in the nursery stage, fall nitrogen fertilization had significant effect on needle nitrogen

concentration, but had no significant effects on seedling morphological characteristics. Needle nitrogen

concentration was increased by the fall fertilization compared to control (0 g N/m²). When measured at two

months after planting, height increments of seedlings fertilized with high nitrogen rate (10 g N/m² and 20 g

N/m²) were higher than the others. The effects of 10 and 20 g N/m² treatments are similar. Therefore, fall

fertilizer applications with 10 g nitrogen per square meter may be useful to height growth, can be safely said at

this stage. However, the study period was quite insufficient to make recommendations on planting performance.

Anadolu Karaçamı (Pinus nigra ssp. nigra Arn. var. caramanica (Loudon) Rehder) Fidanlarında Sonbahar Gübrelemesi

Öz

Bu çalışmada sonbaharda uygulanan azot gübrelemesinin 2+0 yaşlı Anadolu karaçamı (Pinus nigra ssp.

nigra Arn. var. caramanica (Loudon) Rehder) fidanlarının kalitesi ile dikimden sonraki erken boy gelişimi ve

azot konsantrasyonu üzerine etkileri araştırılmıştır. Bu amaçla Eğirdir Orman Fidanlığında Anadolu karaçamı

fidanlarına 28 Eylül – 18 Ekim tarihleri arasında granül formunda 0, 5, 10 ve 20 g N/m² oranlarında amonyum

sülfat [(NH4)2SO4] gübresi uygulanmıştır. Gübreleme işlemleri tamamlandıktan bir hafta sonra (Ekim 2009) ve

dikim öncesinde (Mart 2010) fidan morfolojik özellikleri ile ibre azot konsantrasyonu belirlenmiştir. Fidanlar

mart başında araziye aktarılmış ve dikimden iki ay sonraki erken boy gelişimi ve ibre azot konsantrasyonu

değerlendirilmiştir. Elde edilen sonuçlara göre, fidanlık aşamasında sonbaharda uygulanan azot gübrelemesi

fidan morfolojik özellikleri üzerinde etkili olmamasına karşın, ibre azot konsantrasyonu üzerinde etkilidir.

Sonbahar gübrelemesi ibre azot konsantrasyonunu kontrol (0 g N/m²) işlemine kıyasla önemli ölçüde arttırmıştır.

Dikimden iki ay sonra yapılan tespitlerde yüksek azot içeriğine (10 g N/m² ve 20 g N/m²) sahip gübre verilen

fidanlar daha fazla boy artımı yapmıştır. 10 g N/m² ve 20 g N/m² dozlarının etkisi ise benzerdir. Bu nedenle,

metrekareye 10 g azot olacak şekilde sonbahar azot gübrelemesi uygulanmasının boy gelişimi için faydalı

olabileceği, şu aşamada rahatlıkla söylenebilir. Bununla birlikte dikim performansına ilişkin önerilerde

bulunabilmek için çalışma süresi oldukça yetersiz kalmıştır.
