Step 1: Recall basin irrigation.
In basin irrigation, water is applied to a circular/square basin around plant roots.
Step 2: Advantages.
1. Efficient water use: Deep percolation around roots ensures minimal wastage.
2. Best for fruit trees: Provides uniform supply of water to deep-rooted perennials.
Step 3: Conclusion.
Thus, the two advantages are efficient water use and suitability for fruit trees.
