The College of Agriculture at the University of Kirkuk discussed a Master’s thesis titled “Response of Three Beet Varieties to Putrescine Foliar Application and Its Effect on Growth, Yield, and Consumer Quality Traits” submitted by the student Hadeel Hamed Sarheed.
The study aimed to evaluate the suitability of three beet varieties for cultivation in Kirkuk Governorate, examine the effect of putrescine foliar application on improving beet growth and yield, determine the most effective concentration, and assess the sensory characteristics of beet roots—including size, shape, color, and firmness—in order to identify the best-performing variety.
The study concluded that there were clear differences among the three beet varieties in their responses to the experimental treatments, highlighting the role of genetic factors in determining growth efficiency, productivity, and adaptability to local environmental conditions. The results showed that the variety Fredi V3 had a significant effect on most of the studied traits and recorded the highest values.
The findings also demonstrated that foliar application of the plant growth regulator putrescine significantly improved most vegetative growth, root growth, and sensory quality characteristics of beet plants compared with the untreated control treatment.
