Abstract: An experiment was conducted to study the effect of soil and foliar application of zinc on growth and yield parameters of sweet orange (Citrus sinensis L. Osbeck) Cv. Nucellar.” was carried out at Sweet Orange Research station, Badnapur, Dist. Jalna during 2017-18.The experiment was laid out in Randomized Block Design (RBD) with 12 treatments and three replication. Observations were recorded on growth and yield characteristics of sweet orange. The results were revealed that, there were significant variations in growth, and yield of sweet orange due to application soil and foliar application of zinc.The values of vegetative growth parameters stem girth, plant spread and number of branches per tree showed the non- significant effect by treatments and plant height and canopy volume no.of flowers per branch and fruit drop showed significant effect by the treatments. The height of tree, canopy volume showed most effective in T₁₀ (Soil application ofZnSO₄@150gm+ Foliar spray ofZnSO₄@0.50%) and all treatment superior over the control except (T₁and T₄) and minimum effective in T₁ i.e. control. The physical parameter of fruit like average diameter of fruit most effective in T₁₀ (Soil application ofZnSO₄@150gm+ Foliar spray of ZnSO₄@0.50%) followed by treatment T₁₁(Soil application of ZnSO₄@100gm+ Foliar spray of ZnSO₄@0.75%) and T₁₂(Soil application ofZnSO₄ @150gm+ Foliar spray of ZnSO₄@0.75%) and minimum effective in T₁ (control).the yield parameters number of fruit per tree and weight of fruit per tree, weight of one fruit and weight of five fruit were noticed maximum in T₁₀ (Soil application ofZnSO₄@150gm+ Foliar spray of ZnSO₄@0.50%) followed by treatment T₁₁(Soil application of ZnSO₄@100gm+ Foliar spray of ZnSO₄@0.75%) and T₁₂(Soil application ofZnSO₄ @150gm+ Foliar spray of ZnSO₄@0.75%) and minimum effective in T₁ (control).application of T₁₀ (Soil application ofZnSO₄@150gm+ Foliar spray of ZnSO₄@0.50%) improved economics in sweet orange.
