EFFECT OF DIFFERENT LEVELS OF NITROGEN AND PHOSPHORUS ON THE YIELD AND YIELD COMPONENT OF FALSE FLAX (Camelina sativa L.) CRANTZ)

Abstract

vejetasyon dönemlerinde Ankara ekolojik koşullarında yürütülmüştür. Deneme Tesadüf Bloklarında Bölünen Parseller Deneme Deseni'ne göre üç tekerrürlü olarak kurulmuştur. Denemede ana parsellere fosfor dozları (0, 3, 6, 9 kg/da), alt parsellere de azot dozları (0, 5, 10, 15, 20 kg/da) uygulanmıştır. Bu çalışmanın amacı; ketencik (Camelina sativa (L.) Crantz) bitkisinde farklı fosfor ve azot dozlarının bitki boyu (cm), yan dal sayısı (adet/bitki), 1000 tohum ağırlığı (g), dekara tohum verimi (kg/da), yağ oranı (%) ve yağ asidi kompozisyonu üzerine etkisini belirlemektir. Fosfor ve azot dozlarına bağlı olarak 2011-2012 vejetasyon döneminde ortalama bitki boyunun 52.7-66.0 cm, yan dal sayısının 3.7-8 adet/bitki, 1000 tohum ağırlığının 1.18-1.31 g, tohum veriminin 87.53-181.13 kg/da ve yağ oranının %23.67-31.73 arasında olduğu; 2012-2013 vejetasyon döneminde ise ortalama bitki boyunun 116.4-129.7 cm, yan dal sayısının 5 ile 9.7 adet/bitki, 1000 tohum ağırlığının 1.19-1.48 g, tohum veriminin 106.61-419.82 kg/da ve yağ oranının %24.23-32.30 arasında değiştiği belirlenmiştir. Çalışmada elde edilen verilere göre uygun yağış şartlarında en yüksek tohum verimi için toprakta 9-11 kg/da fosfor ve 20 kg/da azot bulunması yeterli olmaktadır. , number of branches per plant, 1000 seed weight (g), the seed yield (kg) and oil content (%) among different phosphorous doses and nitrogen doses ranged from 116.4 to 129.7 cm, 5 to 9.7 number, 1.19 to 1.48 g, 106.61 to 419.82 g and 24.23 to 32.3% respectively. According to in this study, the highest seed yield were obtained from the application of 6 kg/da of phosphorus and 15 kg/da of nitrogen in the appropriate precipitation conditions.

Effects of Different Sowing Times and Phosphorus Application on Yield and Quality of Camelina (Camelina sativa L. Crantz)

“…Results showed that the most thousand seeds weight (1.04 g) was recorded at 7-10 April using 80 kg ha -1 phosphorus. It was observed before that effects of phosphorus doses on thousand seeds weight (1.28-1.31 g) in camelina were significant which are in contrast with our results (Arslan et al, 2014). Also, in another study, it was showed that different sowing times had significant effects on thousand seeds weight (0.22-0.62 g) (Katar et al, 2012a).…”

“…40 and 80 kg ha -1 P 2 O 5 applications were at the same groups. Arslan et al (2014) showed that the highest number of branches (8.9) obtained by using 60 kg ha -1 P fertilizer while the least number (6.4) recorded in control plots. It was reported that number of branches were 8.28-12.43 at different sowing times (Katar et al, 2012b) which is compatible with the results of present study.…”

“…Katar et al (2012b) observed that oil content was affected by different sowing times and it was ranged between 29.32 to 33.99 %. Also, Arslan et al (2014) showed that oil content varied between 25.31 to 29.65% based on phosphorus treatments. Yıldırım, (2015) also reported that the highest oil ratio (29.33%) was obtained by using 100.0 kg ha -1 phosphorus application and the highest oil yield (579.3 kg ha -1 ) was recorded using 75 kg ha -1 phosphorus treatment.…”

“…The maximum first capsule height (28.56 cm) was determined by using 40 kg ha -1 of phosphorus while the lowest first capsule height (24.22 cm) was determined by using 80 kg ha -1 of phosphorus as the same statistical group with control. Arslan et al, (2014) has indicated that highest plant height (124.5 cm) obtained by using 90 kg ha -1 phosphorus. Yıldırım, (2015) also showed that the most plant height (92.24 cm) and the most first capsule height (77.65 cm) were obtained by using 125.0 kg ha -1 phosphorus while the lowest values (89.99 and 75.33 cm, respectively) were observed by using 100.0 kg ha -1 .…”

“…Phosphorus has also significant effects on plant growth increasing as well as root, seeds, flowers and fruit growing (Reigosa et al, 2004). Several parameters of camelina such as seed yield, number of branches, plant height and number of branches per plant were increased using phosphorus treatment (Arslan et al, 2014). This study was carried out in the aim of effects of different sowing time and phosphorus treatments on yield and yield parameters as well as oil content of camelina in Van region in Turkey.…”
