The master’s thesis in the Department of Horticulture and Garden Engineering at the College of Agriculture, University of Kerbala, discussed the effect of adding Bisc Max fertilizer and spraying with the growth regulator Brassinolide on some qualitative and productive traits of date palm, Barhi variety. The thesis, entitled “The Effect of Adding Bisc Max Fertilizer and Spraying with the Growth Regulator Brassinolide on Some Qualitative and Productive Traits of Date Palm, Barhi Variety,” by student Qahtan Mohammed Abdul Hussein, was divided into three chapters: an introduction and literature review, as well as chapters on materials and methods, and results and discussion.
The thesis aimed to determine the optimal amount of Bisc Max fertilizer to improve the physical and chemical traits of Barhi date palm fruits, in addition to the best concentration of the growth regulator Brassinolide to increase the percentage of fruit set, reduce the rate of fruit drop, and improve the productive traits of Barhi fruits. The study also examined the interaction effect between Bisc Max fertilizer and the growth regulator Brassinolide in improving the vegetative, qualitative, and productive traits of Barhi date palms.
