The present\\r\\ninvestigation entitled “Effect of micronutrients on growth and yield of bottle\\r\\ngourd (Lagenaria siceraria L.)” was carried out during the year\\r\\nof 2023-24 Kharfi season 2023-24, at Department of Horticulture, Chandra Bhanu\\r\\nGupta Agriculture PG College, Lucknow (UP). The different levels of\\r\\nmicro-nutrients (T₀: control-water spray, T₁: ZnSO₄ 0.25%, T₂: ZnSO₄ 0.5%, T₃: ZnSO₄ 0.75%, T₄: boric acid 0.2%, T₅: Boric acid 0.3%\\r\\nand T₆: boric acid 0.4%) were used. The experimental\\r\\nresults revealed that the maximum length of vine (410.10cm) and maximum length\\r\\nof internode (15.20cm) was recorded with application of boric acid 0.2%. While\\r\\nnumber of branches per plant was highest with boric acid 0.4%. In respect of\\r\\nflowering, minimum days to first male flower (48.8) and female flower (60.0)\\r\\nwere noticed with treatment T₂ (ZnSO₄ 0.5%). However, number of fruit per vine (5.9), average fruit weight\\r\\n(703.20g), fruit yield per plot (24.80kg) and per hectare (298.3q) were found\\r\\nto be maximum with the application of ZnSO₄ 0.75% (T₃).
