Different methods of planting an orchard:
1. Square system - The field is devided
into squares as per spacing. In this case a
sapling is planted on each vertex of a square
whatever may be the planting distance.
This plan is commonly followed. It is easy
to layout. Convenient for inter cropping and
cultivation is possible in two directions e.g.
mango (10 × 10 m), banana (1.25 × 1.25 m).
Each plant gets equal area for growth and
