Kirkuk University discusses the evaluation of growth, productivity and weed control of yellow corn.

A master's thesis at the College of Agriculture discussed the evaluation of the growth, productivity and weed control of yellow corn (Zea mays L.) using some chemical pesticides at different planting distances, by the student Sardar Abdul Jabbar Abdul Qader, under the supervision of Dr. Abbas Abdullah Taha, and Professor Dr. Suhad Madkour Abdul Sahib.

The study aimed to evaluate the performance of yellow corn under different planting distances, using several weed killers to determine the best plant distance and the best weed killer, by giving the best control rate and the best inhibition rate and its reflection on growth and grain yield.

The study concluded that the plant density of 66600 plants/h-1 is the best density in terms of weed competition and reducing its density, as it gave the lowest weed density for all periods and the best percentage of control, and that the pesticide Nicosulfuron excelled in giving the best averages compared to the rest of the pesticides used, as it reduced the weed density and gave the best percentage of control.
