Kirkuk University discusses the effect of mulching and spraying with salicylic acid on two varieties of young grape vines

A master’s thesis at the College of Agriculture discussed the effect of covering and spraying with a salicylic growth regulator on the vegetative growth and mineral content of two varieties of young grape vines, by student Hana Aziz Bayiz, and under the supervision of Assistant Professor Dr. Suzan Ali Hussein, and Assistant Professor Dr. Osamah Ibrahim Ahmed.

The study aimed to determine the effect of covering the soil with sawdust and charcoal in improving the characteristics of vegetative growth and the mineral content of grape vines, and to study the effect of the growth regulator salicylic acid on the growth of grape vines and to determine the extent of the response of the Al-Halwani and Al-Kamali varieties to the factors mentioned above.

The study concluded that the triple interaction between covering the soil with charcoal and spraying with the growth regulator salicylic acid at a concentration of 150 mg.l-1 and the Kamali variety led to achieving the best results in the studied traits.
