The present investigation was carried out to study the uptake of micronutrients in soybean growing soils of Dharwad taluk during 2015-16 kharif season. For this purpose 51 representative soybean growing soils of Dharwad taluk were selected. Based on the average grain yields in 51 fields, the entire group was divided into below average and above average yield categories. Mean yield of 51 fields was 14.67 q ha-1. Crop cutting experiment from the selected farmers’ fields were carried out for recording yield data. The study revealed that micronutrient uptake in below average yield category ranged from 45.01 to 68.44 g ha-1 with a mean value of 55.90 g ha-1, 84.28 to 108.05 g ha-1 with a mean value of 99.49 g ha-1, 490.72 to 690.61 g ha-1 with a mean value of 643.28 g ha-1 and 91.26 to 140.74 g ha-1 with a mean value of 118.67 g ha-1 of Cu, Zn, Fe and Mn respectively. The micronutrient uptake in above average yield category ranged from 56.24 to 78.85 g ha-1 with a mean value of 68.72 g ha-1, 113.45 to 141.14 g ha-1 with a mean value of 128.68 g ha-1, 718.33 to 874.25 g ha-1 with a mean value of 795.61 g ha-1 and 104.14 to 162.16 g ha-1 with a mean value of 134.25 g ha-1 of Cu, Zn, Fe and Mn respectively. Among micro nutrients, available zinc and iron were found to be positively and significantly correlated with dry matter production in both below average and above average yield categories.
