A master’s thesis at the College of Agriculture at Karbala University examined the effect of water management on maize cultivation. The thesis entitled (The effect of water quality and spraying with ascorbic and ascorbic lion on the growth and yield of yellow maize) by the student (Qasim Laftah Hamada) included four chapters, namely the introduction, review of sources, materials and working methods, results and discussion.
The study aimed to find out the tolerance of maize plant to salinity in irrigation water and study the response of the plant to spraying with asmosterase and ascorbic acid in terms of growth and yield.
The study concluded that the best results for the growth and yield of maize plants were when irrigated with river water, while irrigation with well water was the worst. It follows from this the effect of salinity on the growth and yield of maize plants in general. The study also found the importance of foliar feeding (spraying with ascorbic acid and osmosterase) in increasing the growth and yield of maize plants because of the role of these nutrients in increasing the adaptation of maize plants to salt stress.
