Abstract:
The present investigation entitled “Influence of nano nitrogen and zinc sulphate on growth characteristics of lemon” was conducted at S. K. N. College of Agriculture, Jobner (Rajasthan) during 2021 on four years old uniform plants of lemon var. Pant Lemon-1. The experiment comprising of 16 treatment combinations with four levels of nano nitrogen (N₀-control, N₁ – nano nitrogen @ 1.50 ml/plant, N₂ – nano nitrogen @ 3.0 ml/plant and N₃ – nano nitrogen @ 4.50 ml/plant) and four levels of zinc sulphate (Z₀-control, Z₁- ZnSO₄ @ 0.40%, Z₂- ZnSO₄ @ 0.80% and Z₃- ZnSO₄ @ 1.20%) in Factorial Randomized Block Design with three replications. The application of treatment N₃ (Nano nitrogen @ 4.50 ml/plant) significantly increased growth characters viz., increment in plant height (27.64 cm), plant girth (4.96 cm), plant spread N-S (28.35 cm), plant spread E-W (30.02 cm), shoot growth (15.43 cm) and chlorophyll content (1.85 mg/g). Further, the foliar application of treatment Z₂ (ZnSO₄ @ 0.80%) significantly increased in growth parameters viz., increment in plant height (27.48 cm), plant girth (4.91 cm), plant spread N-S (28.31 cm), plant spread E-W (30.12 cm), shoot growth (15.33 cm) and chlorophyll content (1.83 mg/g).
