This study aimed to assess the effectiveness of different fertilizers doses with organic manures on micronutrients availability in turmeric (Curcuma longa L.). A field experiment in completely randomized block design was conducted with eight treatments which were replicated thrice. The eight treatments were comprised of four soil test crop response based treatments along with farmer’s practice, general fertilizer dose, soil test based and absolute control. Results of the study showed that STCR based treatment of targeted yield 40 t ha-1 documented highest concentrations of micronutrients viz. Fe (21.23 mg kg-1), Mn (18.58 mg kg-1), Zn (0.83 mg kg-1) and Cu (0.62 mg kg-1) in soil. Moreover, similar treatment also recorded highest concentrations of micronutrients in turmeric rhizome and straw. Regarding the micronutrient uptake, highest values of uptake were associated with the targeted yield treatment of 40 tha-1 i.e. Fe, Mn, Zn and Cu uptake in rhizome (1414, 696, 564 and 629 g ha-1, respectively) while in straw (84.5, 77, 65.6 and 78.5g ha-1, respectively). Higher concentrations and uptake of micronutrients at the harvest of crop advocated the superiority of STCR over the traditional fertilization approaches. The study concluded that the practice of STCR could be recommended to turmeric grown under Alfisol.
