A Master’s thesis at the College of Agriculture, University of Kirkuk, examined the effects of pinching, benzyladenine spraying, and the application of compound NPK fertilizer on the growth and flowering of myrtle plants.
The thesis, submitted by student Mohammed Ali Musa Abdullah, aimed to compare the mechanical and hormonal effects on the growing tips of the plant’s main and lateral branches by measuring growth increments and comparing them with untreated plants that had neither been pinched nor sprayed with the growth regulator benzyladenine. It also sought to stimulate vegetative growth using different levels of compound NPK fertilizer, assess its role in improving the vegetative and flowering characteristics of myrtle plants, and identify the best combination of the studied treatments for use under local environmental conditions.
The study concluded that the agricultural treatments used in the experiment had a significant effect on the studied characteristics of myrtle plants.
