Effect of some organic fertilizers on yield and yield components of barley

Sufficient soil fertilization is one of the main requirements for production of barley improvment. To study the effect of different organic fertilizers on yield and yield components of barley cv. Reyhan, an experiment was conducted based on randomized complete block design with three replications with 16 fertilizer compounds. Barley morphological traits, yield and yield components were measured. Treatments were included wood vinegar, 5, 10, and 150/00 as soil application, azocompost, zeolite, wood vinegar, 5, 10, and 150/00 as foliar spraying, wood vinegar, 5 and 100/00 + azocompost, wood vinegar, 5 and 100/00 + zeolite, humic acid, wood vinegar, 5 and 100/00 + humic acid. Application of wood vinegar at 50/00 rate + zeolite significantly increased leaf area and plant dry weight. Also, using vinegar at 100/00 rate + zeolite significantly increased spike length and grain yield. Application of vinegar at the rate of 100/00 with zeolite is recommended in barley cultivation.
