Şanlıurfa Koşullarında Farklı Aspir Çeşitlerinin (Carthamus tinctorius L.) Uygun Ekim Zamanlarının Belirlenmesi

Abstract

This research was carried out to determine at suitable sowing time of different safflower (Carthamus tinctorius L.) cultivars on Sanliurfa conditions. The research was conducted at Koruklu Research Station of GAP Agricultural Research Institute at the three growing seasons (2007- 2008, 2008-2009, 2009-2010). The trial was established Dincer and Remzibey-05 as the kind for sub treatment and sowing time (October 30, November 15, November 30, December 15, February 20, March 7, March 22 and April 5) for the main treatment in the experiment designed as split plots in randomized blocks as 4 replications. As a result, plant height, branch number, number of heads, head 2 diameter, thousand seed weight and seed yield differences is significant (p <0.01) in terms of planting dates. The highest yield (426 kg/da) is taken I. sowing on October 30 while the lowest yield (98 kg/da) was obtained XIII. sowing on April 5 among planting dates according to the three-year averages. According to sowing time x cultivar interaction, the highest yield (447 kg/da) is taken from Remzibey – 05 variety on October 30 while the lowest yield (95 kg/da) was obtained Dincer sowing on April 5 among planting dates according to the three-year averages.
