The Department of Biology is Holding a Seminar for a Doctoral Student on the Effect of Spraying Kinetin and Potassium on the Tolerance of Maize to Different Irrigation Water Salinity Levels
As part of a series of scientific activities organized by the Department of Biology, a seminar was held for doctoral student Farah Nasr Shiaa, titled “The Effect of Spraying kinetin and potassium on the Tolerance of maize (Zea mays L.) to Different Irrigation Water Salinity Levels,” under the supervision of Asst. Prof. Dr. Ban Musa Hassan. This seminar aimed to study the effect of spraying with the growth regulator “kinetin” and potassium fertilizers (conventional and nano) on improving maize plant tolerance to irrigation water salinity. A factorial experiment was conducted with three salinity levels (S1, S2, S3), different concentrations of kapentin (KN0, KN1, KN2), and two types of potassium (K0, K1, K2), measuring 17 growth, yield, and physiological response indicators. The research results also identified the optimal concentration of capentene and the best type of potassium to enhance corn yields under salt stress, especially in arid regions such as Iraq, where salinity threatens 20% of agricultural land. The results indicated that combined treatments (especially nanopotassium and capentene) can improve nutrient uptake and mitigate the harmful effects of salinity, contributing to secure food production using moderately saline irrigation water.
