Growth And Yield Response of Flax (linum Usitatissimum L.) to Different Rates of Charcoal And Potassium Fertilizer in Erbil, Kurdistan Region-iraq

Abstract

This study investigate the influence of different levels of charcoal and inorganic fertilizer on the some growth and yield parameters of flax crop. The study conducted in GrdarashaField which is belong to the College of Agricultural Engineering Sciences, Salahaddin University – Erbil in the 2017 – 2018growing season. Charcoal has not been yet applied as a fertilizer in flax field and any crops in Kurdistan, therefore its potential effect has been investigated for the first time in this study. Interaction among charcoal and potassium at the rate of (800g/m2 and 60kg/ha), respectively were caused to significantly improve some growth and yield parameterssuch as plant height, technical stem length, total fresh yield and dry stem yield by the about (63.4cm, 46.3cm, 11.5 t/ha and 3.5 t/ha), respectively. Additionally, potassium alone especially at the rate of 60kg/ha showed an impact role to provide high value of both growth and yieldstudied characteristics. On the bright of the results, anopportunity could be seento do more researchesin the future about the effects of charcoal and inorganic fertilizers not only on flax but also on other crops.
