Question

Micro sprinkler method of irrigation has the advantages of both

• A. Sprinkler and drip irrigation methods
• B. Sprinkler and surface irrigation methods
• C. Drip and surface irrigation methods
• D. Surface and subsurface irrigation methods

Hint:

Micro-sprinkler = The "Middle Ground."
It saves water like Drip but cools the leaves like a Sprinkler.
It's the "hybrid" solution for modern horticulture.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
The question asks to identify which two traditional irrigation systems contribute their specific benefits to the "Micro-sprinkler" system.
Detailed Explanation:

• Features of Micro-sprinklers:
Micro-sprinklers (also called mini-sprinklers or sprayers) are low-pressure, low-volume irrigation devices.
They throw water over a small area ($3-6$ meter diameter) using a rotating or fixed head.

• Advantages from Drip Irrigation:
Like drip, they operate at low pressures ($1.5-2.5$ kg/$cm^2$).
They apply water locally near the root zone rather than wetting the entire field.
They allow for fertigation (applying fertilizers through water).

• Advantages from Sprinkler Irrigation:
Like sprinklers, they spray water into the air, which increases humidity and decreases the air temperature around the plant.
This "micro-climate" modification is excellent for frost protection and cooling high-value crops like leafy vegetables or orchards in hot weather.
Unlike drip emitters, micro-sprinklers have larger orifices and are less prone to clogging by sand or biological growth.

• Suitability:
They are ideal for wide-spaced orchards (like Citrus or Mango) and greenhouse crops where both root-zone moisture and humidity control are required.

Step 2: Final Answer:
Micro-sprinklers combine the localized, water-saving efficiency of drip with the micro-climate cooling benefits of sprinklers.
