The effects of spring and autumn sowing on yield and some morphological characteristics in fenugreek (Trigonella foenum- Graecum L.)

This study was conducted to determine the optimal sowing period of fenugreek (Trigonella foenum-graceum L.) in Yozgat ecological conditions, to investigate the effect of spring and autumn sowing on yield and yield components of fenugreek at Research and Application Area of Gedikhasanlı, Faculty of Agriculture, Bozok University during 2014-2015 vegetation period. Gürarslan fenugreek variety was sown on 22 October 2014 and 17 April 2015. According to results of this research; plant height 46.58 cm, 32.42 cm; the number of pods per plant 16.73 number, 6.65 number; the number of seeds per pod 9.75 number, 5.27 number; thousand seed weight 30.17 g, 24.72 g; seed yield 310.93 kg/da, 154.23 kg/da; biological yield 819.92 kg/da, 791.31 kg/da; harvest index 37.56%, 20.13%; oil ratio 4.61%, 4.28%; oil yield 14.45 kg/da, 6.61 kg/da and protein ratio 30.04%, 29.74% were recorded in autumn and spring sowing, respectively. The effect of autumn sowing on all properties investigated was positive and except for biological yield and protein ratio, significant statistically. The increasing ratio of these characters in autumn sowing according to spring sowing was 43.56%, 151.62%, 85.15%, 22.04%, 101.60%, 3.62%, 86.54%, 7.86%, 118.71% and 1.02%, respectively.
