The effect of humic acid and potassium applications on the yield and yield components in chickpea (Cicer arietinum L.)

The study was conducted to determine effects of different levels of humic acid and potassium on the yield and some yield components in chickpea in 2017 in Mardin City. The experiment was laid out in a factorial randomised block design with three replications. The doses were used potassium (0, 10 and 20kg/da) and humic acid (0, 30 ve 60 kg/da) in this study. In the study were investigated the plant height, first pod height,branch number per plant, pod, seed number and per plant, seed number per pod, biological yield, seed yield per unit, harvest index, 100-seed weight, protein ratio and potassium content in seed. The results of the study indicated that humic acid and potassium applications increased significantly the seed yield and yield components. The highest seed yield was obtained from 20 kg phosphorus /da+ 60 kghumic acid /da application as 286.9 kg/da.
