The present investigation entitled “Effect of foliar application of micronutrients on yield of turmeric” was carried out during kharif season 2023-24 at the Horticulture Research Cum Instructional Farm, Barrister Thakur Chhedilal College of Agriculture and Research Station, Bilaspur (C.G.). The experiment was laid out in Randomized Block Design with three replications. The treatments consisted of ten nutrient management practices viz., Control (T₁), RDF: 120:50:80 NPK (T₂), Foliar Spray MnSO₄ @ 0.5% 60 DAS (T₃), Foliar Spray FeSO₄ @ 0.5% 60 DAS (T₄), Foliar Spray Borax @ 0.5% 60 DAS (T₅), Foliar Spray ZnSO₄ @ 0.5% 60 DAS (T₆), Foliar Spray MnSO₄ @ 0.5% 60 & 90 DAS (T₇), Foliar Spray FeSO₄ @ 0.5% 60 & 90 DAS (T₈), Foliar Spray Borax @ 0.5% 60 & 90 DAS (T₉) and Foliar Spray ZnSO₄ @ 0.5% 60 & 90 DAS (T₁₀). The experiment's findings showed that the treatment (T₈) Foliar Spray FeSO₄ @ 0.5% 60 & 90 DAS have registered higher growth, yield attributes and yield of turmeric crop, which was similar with (T₇) Foliar Spray MnSO₄ @ 0.5% 60 & 90 DAS, (T₉) Foliar Spray Borax @ 0.5% 60 & 90 DAS and (T₁₀) Foliar Spray ZnSO₄ @ 0.5% 60 & 90 DAS. The next best treatment was (T₄) Foliar Spray FeSO₄ @ 0.5% 60 DAS, followed by (T₃) Foliar Spray MnSO₄ @ 0.5% 60 DAS, (T₅) Foliar Spray Borax @ 0.5% 60 DAS and (T₆) Foliar Spray ZnSO₄ @ 0.5% 60 DAS. Significantly highest N, P, K and S uptake by turmeric plant and available N, P₂O₅, K₂O and S in soil after harvest were tested under (T₈) Foliar Spray FeSO₄ @ 0.5% 60 & 90 DAS. In turmeric rhizome, significantly the highest available Mn was tested in soil under the treatment plot (T₇) Foliar Spray MnSO₄ @ 0.5% 60 & 90 DAS. The maximum amount of accessible Fe in the soil underneath the treatment plot (T₈) Foliar Spray FeSO₄ @ 0.5% 60 & 90 DAS. The treatment plot (T₁₀) Foliar Spray ZnSO₄ @ 0.5% 60 & 90 DAS exhibited the maximum accessible Zn in the soil. The maximum amount of accessible B in the soil underneath the treatment plot (T₉) Foliar Spray Borax @ 0.5% 60 & 90 DAS. Soil chemical properties viz., EC, pH and organic carbon of soil after harvest of turmeric crop, tested non-significant variation between the nutrient management practices.
