In this study, the effects of different humic acid doses and different sowing dates on yield and morphological characteristics of fenugreek plants were investigated and evaluated by two factorial variance analysis and by PCA (principal component analysis). Experiments were conducted over the experimental fields of Erciyes University in Turkey during the summer growing season of the years 2014 and 2015 in randomized blocks – split plots experimental design with 4 replications to determine the effects of different humic acid doses and different sowing dates on yield and morphological characteristics of fenugreek plants. Four different sowing dates (1 March, 15 March, 1 April and 15 April) were placed in main plots and 3 different humic acid doses (control, 20, 40 and 60 l ha−1) were placed in sub-plots. Seed yield (kg ha−1), plant height (cm), thousand-seed weight (g), the first pod height (cm), number of branches per plant, pod length (cm), number of pods per plant, number of seeds per pod, biological yield (kg ha−1) and harvest index (%) were investigated. Our data revealed that humic acid treatments did not have significant effects on investigated parameters. However, sowing dates were found to be significant in terms of seed yield. Considering the seed yields of both year together, it can be recommended that fenugreek should be sown between 1 March and 1 April. According to PCA analysis, all humic acid doses during the 4th sowing period did not have a significant effect on yield in 2014 and 2015.

播期和腐殖酸对胡芦巴的影响(Trigonella foenum-graecum L.)

在这项研究中,通过两个因子方差分析和PCA(主要成分分析)研究和评估了不同腐殖酸剂量和播种日期对胡芦巴植物产量和形态特征的影响。在2014年和2015年夏季生长季节期间,在土耳其Erciyes大学的实验田间进行了随机区组试验-分割地块实验设计,重复4次,以确定不同腐殖酸剂量和播种日期对产量和产量的影响。胡芦巴植物的形态特征。将四个不同的播种日期(3月1日,3月15日,4月1日和4月15日)放置在主要地块中,并添加3种不同的腐殖酸剂量(对照,20、40和60 l ha -1)放置在子图中。种子产量(kg ha -1),植物高度(cm),千粒重(g),第一个荚果高度(cm),每株植物的枝条数,荚果长度(cm),每株植物的荚果数每荚的种子数量,生物产量(kg ha -1)和收获指数(%)进行了研究。我们的数据表明,腐殖酸处理对所研究的参数没有显着影响。然而,发现播种日期在种子产量方面很重要。综合考虑两年的种子产量,建议在3月1日至4月1日之间播种葫芦巴。根据PCA分析,在2014年和2015年,4播种期的所有腐殖酸剂量均未对产量产生重大影响。
