Plant Taxonomy

Step 1: Understanding the Concept:
This question tests the knowledge of plant taxonomy, specifically the botanical families to which certain fruit plants belong.

Step 2: Detailed Explanation:
Let's examine each pair:
Thus, the correct combinations are (B), (C), and (D).

Step 3: Final Answer:
The combinations that are botanically correct are Loquat-Rosaceae, Phalsa-Tiliaceae, and Jamun-Myrtaceae. Therefore, the correct option is (B), (C) and (D) only.

Concept: Efficient water management is crucial in arid and semi-arid regions where water is scarce. Irrigation methods must minimize water loss and maximize efficiency.
Step 1: Understanding water scarcity.
In dry regions, evaporation and water wastage must be minimized.
Step 2: Drip irrigation advantage.
Drip irrigation delivers water directly to the root zone in small quantities, reducing evaporation and runoff losses.
Step 3: Evaluating the options.

• Flood irrigation High water loss (incorrect)
• Sprinkler irrigation Moderate efficiency, some evaporation loss (incorrect)
• Drip irrigation Most efficient, minimal wastage (correct)
• Basin irrigation Not suitable for water-scarce areas (incorrect)

Step 4: Additional insight.
Drip irrigation also improves fertilizer use efficiency (fertigation) and reduces weed growth.
Step 5: Conclusion.
Thus, drip irrigation is most suitable for arid and semi-arid horticultural regions.
