Abstract:
This study aims to evaluate the efficacy of nitrogen and spacing on lettuce performance. The experiment was laid out as a randomized block design (RBD) with four N levels N₀ (0 kg/ha), N₁ (60 kg/ha), N₂ (120 kg/ha) and N₃ (180kg/ha) and three different spacing S₁ (45 cm × 20 cm), S₂ (45 cm × 25 cm) and S₃ (45cm ×30 cm). In case of nitrogen the highest plant height (11.97, 23.14 and 29.12 cm), number of leaves/plant (12.98, 21.11 and 24.42), leaf length (13.04, 18.97 and 25.97 cm) and leaf width (12.78, 16.15 and 28.68 cm) at 30, 45 and 60 DAT was recorded from N₃ and likewise, the effect of spacing gave maximum plant height (11.33, 21.53 and 27.38 cm), number of leaves/plant (14.42, 23.78 and 27.17), leaf length (12.44, 17.60 and 25.75 cm) and leaf width (11.97, 15.05 and 25.10 cm) at 30, 45 and 60 DAT respectively was observed from S_3. For interaction effect, plant height (12.89, 23.58 and 29.37cm), number of leaves/Plant (16, 27.70 and 32.64), leaf length (14.08, 19.80 and 29 cm) and leaf width (13.80, 17.28 and 30.36 cm) at 30, 45 and 60 DAT respectively was found from N₃S₃. This study showed that for optimal growth of lettuce ought to be grown using nitrogen level 180 kg N ha⁻¹ and spacing 45 x 30 cm.
