An investigation entitled Standardization of Plant Spacing and Node Pruning in Basil under the DWC technique of Aquaponics was conducted at the Landcraft Aquaponic Unit, Hatkangle. The experiment was laid out in a Factorial Completely Randomized Design (FCRD) with four different plant spacing treatments: S₁ (10 cm × 10 cm), S₂ (15 cm × 10 cm), S₃ (20 cm × 10 cm), and S₄ (20 cm × 20 cm), and four different node pruning treatments (cutting after node 2, node 3, node 4, and node 5), comprising 16 treatments, each replicated twice. Basil seedlings were transplanted with different spacing treatments, and observations were made on various growth parameters. Among the four spacing treatments, the wider spacing (20 cm × 20 cm) significantly improved growth parameters, including the number of leaves, plant height, plant yield and root length. Regarding the node pruning treatments, cutting after the 5^th node (C₄) resulted in taller plants. These results suggest that for maximum yield occurs with combination of wider spacing (20 cm × 20 cm) and cutting after the 5^th node is most beneficial for basil cultivation.
