A master’s thesis at the College of Agriculture examined the effect of mushroom farm residues and water stress on some soil physical properties, as well as on the growth and yield of maize, using both surface and subsurface drip irrigation.
The study, presented by the student Kawther Ismail Rahim, aimed to determine the effect of mushroom residues on certain soil physical properties using surface and subsurface drip irrigation, to identify the impact of water stress on the growth and yield of maize, and to measure water consumption and water-use efficiency of the crop.
The study concluded that using subsurface drip irrigation combined with adding mushroom residues at 2% of the experimental unit’s weight, along with 100% irrigation water, improved the soil’s physical properties and increased growth indicators and maize yield.
