A field experiment was conducted on Typic Haplusterts soils of Vegetable Research Farm, Junagadh Agricultural University, Junagadh, Gujarat, during 2012–2015 (three years) to study the efficacy of multi-micronutrients formulation mixture fertilizers in improving crop production of okra. The results revealed that the mean green pod (12363 kg ha⁻¹), stalk (5056 kg ha⁻¹) and dry pod (1114 kg ha⁻¹) yields increased significantly due to soil application of FeSO₄ @ 15 kg ha⁻¹ and ZnSO₄ @ 8 kg ha⁻¹ as per soil test value (STV), followed by foliar multi-micronutrients supplementation through 1.0% spray of multi-micronutrients mixture having Fe-4.0%, Mn-0.1%, Zn-5.0%, Cu-0.5% and B-0.5% grade-IV (T₅-for Zn and Fe deficiency) at 45, 60 and 75 days after sowing (DAS). Significantly higher value of internode length (8.2 cm), fruit length (13.6 cm), number of fruits per plant (19.9), plant height (129 cm), fruit girth (6.1 cm) and fruit weight (15.9 g) were also recorded with soil application of FeSO₄ @ 15 kg ha⁻¹ and ZnSO₄ @ 8 kg ha⁻¹ as per soil test values (STV). Both the treatments were statistically at par with each other but significantly superior over control. The soil application of multi-micronutrients mixture as per STV or foliar spray 1.0% grade -IV were found beneficial and economical in increasing okra yield.
