Abstract:
The present investigation entitled studies on “effect on root and yield parameters by optimizing the nitrogen level and adjustment of spacing in lettuce” was carried out 2018 – 2019 in rabi season at Horticulture Research Farm-I of the Department of Horticulture, Babasaheb Bhimrao Ambedkar University Vidya-Vihar Raebareli Road, Lucknow (U.P.), India. 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) with three replications. In case of nitrogen the highest yield (109.36 g/plant) was recorded from N₃ and lowest (90.91 g/plant) from N₀. In case of spacing the highest yield (112.18 g/plant) was achieved from S₃ and lowest (85.72 g/plant) from S₀. For interaction effect, the highest yield (128.55 g/plant) was obtained from N₃S₃ and lowest (78.80 g/plant) from N₀S₁. This study showed that for optimal yield parameter of lettuce ought to be grown using nitrogen level 180 kg N ha⁻¹ and spacing 45 cm x 30 cm.
