To determine the effective sprayer coverage, we need to calculate the total area covered by the sprayer in one pass.

Given:
- Number of nozzles: 6
- Boom width: 75 cm
- Tank capacity: 700 liters
- Field calibration: 5/50 ha

First, convert the field calibration from hectares to square meters:
1 hectare = 10,000 square meters
5/50 ha = (5/50) * 10,000 = 500 square meters

Next, calculate the effective spray width of the sprayer:
Effective spray width = Number of nozzles * Boom width
Effective spray width = 6 * 75 cm = 450 cm = 4.5 meters

Now, calculate the effective spray area covered in one pass:
Effective spray area = Effective spray width * Field calibration area
Effective spray area = 4.5 meters * 500 square meters = 2,250 square meters

Therefore, the effective sprayer coverage is 2,250 square meters in one pass.
