Determining the Production Function and Yield Response of Total Dry Matter and Grain to Deficit Irrigation in Maize

This is a research article reporting on a field experiment conducted at the research farm of Islamic Azad University in Dezful, Khuzestan province, during the 2014 to 2015 growing season. The study examines how different irrigation levels affect maize production, focusing on the relationship between water application and yield components including total dry matter, grain yield, and harvest index. The experiment used a randomized complete block design with four irrigation treatments at 60, 80, 100, and 120 percent of full irrigation, each repeated four times.
