Özet
Bu çalışma farklı miktarlarda azotlu gübrelerin bölünerek uygulanmasının Dinçer aspir çeşidinde tohum verimi, verim unsurları, yağ oranı ve yağ verimi üzerine etkisini belirlemek amacıyla 2011 ve 2012 yıllarında Ankara koşullarında yürütülmüştür. Tesadüf blokları deneme desenine göre 3 tekrarlamalı olarak yürütülen bu çalışmada 13 farklı konu (U1: 0 kg N/da, U2: 5 kg N/da tamamı ekimle, U3: 5 kg N/da tamamı rozet döneminde, U4: 5 kg N/da yarısı ekimle + yarısı sapa kalkma başlangıcı döneminde, U5: 5 kg IM/da yarısı ekimle + yarısı rozet döneminde, U6: 10 kg N/da tamamı ekimle, U7: 10 kg N/da tamamı rozet döneminde, U8: 10 kg N/da yarısı ekimle + yarısı sapa kalkma başlangıcı döneminde, U9: 10 kg N/da yarısı ekimle + yarısı rozet döneminde, U10: 15 kg N/da tamamı ekimle, U11: 15 kg N/da tamamı rozet döneminde, U12: 15 kg N/da yarısı ekimle + yarısı sapa kalkma başlangıcı döneminde ve U13: 15 kg N/da yarısı ekimle + yarısı rozet döneminde) uygulanmıştır, iki yıl süreyle yürütülen bu çalışmanın sonuçları, dekara en yüksek tohum ve yağ verimlerinin 15 kg azotun ikiye bölünerek yarısının ekimle ve diğer yarısının sapa kalkma başlangıcında uygulanmasıyla elde edilmiştir.
The aim of this study was to determine the effects of different nitrogen rates applied by dividing on the seed yield, yield components, oil content and oil yield of Dincer safflower cultivar. The study was conducted at randomized complete block design with three replication under Ankara conditions in 2011 and 2012. In the study, 13 different applications (T1 :0 kg/da N, T2: 5 kg N/da at sowing, T3: 5 kg N/da in term of rosette, T4: half of 5 kg N/da with sowing other half part at initiation of stem elongation stage, T5: half of 5 kg N/da with sowing other half part in terms of rosette, T6: 10 kg N/da at sowing, T7: 10 kg N/da in term of rosette, T8: half of 10 kg N/da with sowing other half part at initiation of stem elongation stage, T1: half of 5 kg N/da with sowing other half part in terms of rosettajio: 15 kg N/da at sowing, T10: 15 kg N/da in term of rosette, T12: half of 15 kg N/da with sowing other half part at initiation of stem elongation stage, T13: half of 15 kg N/da with sowing other half part in terms of rosette) were treated. Results from a two-year study on nitrogen application for safflower under Ankara conditions indicated that the highest seed and oil yield were obtained by applying the rate of 15 kg N/da as 1/2 at sowing + 1/2 at initiation of stem elongation stage.
