Question 1: What is the effect of using water with high salinity in a drip irrigation system?

Which action should you take?

Choose only one option

It improves nutrient absorption in plants

It increases the efficiency of the irrigation system

It reduces water consumption in the system

It can cause emitter clogging and soil salinization

Question 2: How often should a filtration system in a drip irrigation system be checked for clogs?

Which action should you take?

Choose only one option

Only during initial installation

Once a year, at the start of the growing season

Every six months regardless of system usage

At least once every month during active irrigation periods

Question 3: How does emitter spacing in a drip irrigation system affect water distribution?

Which action should you take?

Choose only one option

Increased spacing reduces evaporation losses

Wider spacing conserves more water in the soil

Closer spacing is more effective in sandy soils

Wider spacing can result in uneven water application

Question 4: When designing a central pivot irrigation system for large-scale agriculture, which factor should be considered to prevent water wastage?

Which action should you take?

Choose only one option

The distance between sprinklers and the pivot point to ensure even coverage

The use of a single nozzle for all crops regardless of size

Uniform water pressure across the entire system

The material of the pipes used for water distribution

Question 5: When calculating irrigation efficiency, which of the following is not typically included in the formula?

Which action should you take?

Choose only one option

Evaporation and runoff losses

System maintenance and repair costs

Water delivered to the root zone

Cost of irrigation system installation

Question 6: Which of the following is a key factor in determining the irrigation scheduling for a crop field?

Which action should you take?

Choose only one option

Soil texture and the crop's root depth

Irrigation system pressure and flow rates

Crop water demand based on growth stage and weather conditions

All of the above
