Abstract

In order to study the effects of iron and humic acid foliar spraying on yield and yield components of Sardari wheat ecotypes an experiment was conducted in Research Farm of Kurdistan University during growing season 2012-2013. This experiment carried out as split-split plot based on complete randomized block design with three factors and three replications. The studied factors included: ecotypes of Sardari (Ryzhav, Khoshab, Todare, Baghche Maryam, Tazeh Abad, Taluoar, GhatrehZamin, Sofian, Avihang, Siosemardeh, Baharsabz, Gavdarreh and Kalateh) and Azar2 at 14 levels were assigned to the main plots, spraying time in two levels (before and after flowering) were allocated to sub plots, and foliar application at four levels (control, humic acid, iron and humicacid+iron) were placed in sub-sub plots. Results showed among ecotypes, Toodar sprayed with humic acid had the highest yield of 503 gr.m-2. The lowest grain yield belonged to Gavdarreh ecotype with foliar spraying before flowering at the rate of 132 gr.m-2 that had no significant difference with Ryzhav ecotype in spraying before and after flowering and Gavdarreh in foliar spraying after flowering.
