Micronutrients provide multiple benefits to crops, such as boosting crop performance under adverse environmental conditions. This paper demonstrates the effects of micronutrients in mitigating drought stress in soybean. Treatment of the plants with micronutrients mitigated the reduction of nutrient uptake under drought conditions. Nitrogen uptake was significantly increased. Similarly, zinc uptake and grain zinc content were significantly enhanced by the formulations. Therefore, agronomic fortification of zinc in food crops may be an effective strategy for increasing the nutritional quality of edible produce under water limiting conditions.
