Aspir (Carthamus tinctorius L.) Bitkisinde Sıra Arası Mesafe ve Ekim Normunun Verim ve Verim Unsurları Üzerine Etkisi

Öz

Aspir üretiminde verim, sıra arası mesafe ve ekim normu uygulamalarından etkilenmekte olup çeşitlerin bu uygulamalara reaksiyonları farklıdır. Bu nedenle, her çeşit için uygun sıra arası mesafe ve ekim oranının belirlenmesi yüksek verim ve kalite açısından önem taşımaktadır. Bu çalışma, 2011 yılında tescil ettirilen Balcı aspir çeşidi için en uygun sıra arası mesafe ve ekim normunu belirlemek amacı ile yürütülmüştür. Deneme; 2012, 2013 ve 2014 yıllarında, Eskişehir Geçit Kuşağı Tarımsal Araştırma Enstitüsü deneme tarlalarında tesadüf blokları bölünmüş parseller deneme desenine uygun olarak 4 tekerrür halinde ekilmiştir. Çalışmada 3 farklı sıra arası mesafe (15, 30 ve 45 cm) ve 5 ekim normu (15, 30, 45, 60 ve 75 kg ha-1) kullanılmıştır. Çalışmada tane verimi, yağ oranı, yağ verimi, bitkide dal sayısı, tablada tane sayısı ve 1000 tane ağırlığı değerleri incelenmiş olup, sıra arası ve ekim normu uygulamaları tane ve yağ  verimi üzerine farklı etkilerde bulunmuştur. Buna göre; Balcı aspir çeşidi için 30 veya 45 cm    sıra arası mesafe ile 45 kg ha-1 ekim normu uygulamalarının en yüksek tohum ve yağ verimi  elde etmede uygun olduğu tespit edilmiştir.Özellikle, sıcaklığın ve nemin yüksek olduğu aspir üretim alanlarında hastalık gelişimini azaltmak ve mekanik ot kontrolünü sağlamak için 45 cm sıra arası mesafe ile 45 kg ha-1 ekim normunun kullanılmalıdır.

The Influence of Row Spacing and Seeding Rate on Yield and Yield Components of Safflower (Carthamus tinctorius L.)

Öz

In safflower production, yield is affected row spacing, seeding rate and varieties give different response to them. For this reason, determining the optimum row spacing and seeding rate for each variety is important to obtain high yields and quality. In this research was conducted          to determine the effect of row spacing and seeding rate on yield and quality traits of Balci safflower (Carthamus tinctorius L.) variety registrated in 2011. The experiment was conducted  at the Transitional Zone Agricultural Research Institute, Eskisehir, Türkiye using a randomized complete block split-plot design with four replicates in 2012, 2013 and 2014 growing seasons. Three different row spacing (15, 30 and 45 cm) and five different seeding rates (15, 30, 45,      60 and 75 kg ha-1) were used in experiments. Seed yield, oil content, oil yield, the number of branches per plant, the number of seed per head and 1000 seed weight were investigated in this research. As a result of this study significant effect on seed and oil yield was determined in terms of row spacing and seeding rate. It was recommended that Balci safflower variety should be sown with 30 or 45 cm row spacing with 45 kg ha-1 seeding rate to obtain the highest seed and oil yield. Especially, safflower production areas where temperature and humidity is too    high to reduce the development of diseases and provide mechanical weed control 45 cm row spacing with 45 kg ha-1 seeding rate should be used for production
