What is the effect of uneven water distribution in an irrigation system?

Uneven water distribution in an irrigation system leads to decreased crop yield, which is why this answer is the correct choice. When water is not distributed evenly, some areas of the field may receive too much water while others may receive too little. This can result in plants suffering from water stress. Overwatered plants can experience root rot and other issues, while underwatered plants may not have enough moisture to grow properly, leading to stunted growth or even crop failure.

Proper irrigation practices aim for uniform water application, ensuring that all plants receive adequate moisture for optimal growth. Uneven water distribution disrupts this balance, ultimately impacting the overall health and productivity of the crops, leading to a decline in yield. Consistent and efficient irrigation management is crucial to maintaining soil moisture levels and achieving a high-quality crop output.
