The objective of the current study was to examine the effects of micronutrient mixes and their applications as a biofertilizer solution on the growth and metabolism of different plants. There has been a notable progress in our understanding of the critical function "trace metals" play in plant viability and production during the last three decades. The application of nanomaterials has demonstrated potential in enhancing seed germination, nutrient utilization, plant tolerance to environmental challenges, and overall plant growth while minimizing environmental effect when compared to the use of conventional fertilizers and pesticides. It has been discovered that zinc oxide nanoparticles, or ZnO-NPs, are essential for plants to be able to detect and react to abiotic stressors. An attempt has been made to increase the yield per unit of land and increase the farmed area in order to improve the overall productivity and quality of legumes. This has been made possible by the use of high-yielding cultivars and enhanced agronomic techniques, such as fertilization. The application technique (soil, foliar, or the new "seed coat" method at planting) and the source of the micronutrient fertilizer (salts, acids, or chelates) have a major impact on how effective micronutrient fertilization is. Nonetheless, a number of studies have shown that the administration of micronutrients in combination is essential for controlling a number of plant biochemical processes that result in improved yield, growth, and seed quality. The effects of foliar application of liquid metalostates of Fe, Mn, and Zn (amino acids - chelated) on pea and cowpea plants in a pot experiment using loamy soil [21]. Each element's concentration, either alone or in combination, was set at 100 parts per milliliter. When Fe was applied topically alone or in combination with Mn and Zn, the researchers saw a considerable increase in plant development, including plant height, internode length, number of branches, and dry weight. They also found that combining Fe and Mn boosted the number of pods and seed output. The same authors also observed that applying Fe and Mn alone or in combination (with Zn) was the only way to raise the 100-seed weight in pea plants. Although the relationship between ZnO and salt in higher plants has been extensively studied, little is known about the possible benefits of applying ZnO-NP to mitigate the harm that comes with salinity stress. Furthermore, methods such using PGPBs and plant genetic engineering can be used to lessen the stress that salinity causes to plants. The number of branches/plant, pods/plant, and seeds/pod increased in field experiments[23] when Zn was applied as seed coating with Zn0 (at 0.1 and 0.2%) followed by two foliar sprays with ZnSO4 (at 15 and 30 or 15 and 45 days after emergence). Specific seed weight, seed yield/plant, harvest index, and seed yield all increased as well. According to the current study's findings, spraying Zn or Mo, or both together, during the early and late stages of inflorescence after sowing for 96 days (stage II) and 133 days (stage III) significantly improved the fresh and dry weight of bean plant leaves. Comparing treated plants (at stage II) to untreated ones, it was shown that the administration of Zn & Mo at a low level of 50 mg increased the fresh and dry weight of leaves more than the high level of the two mineral ions. Moreover, the fresh and dry weight of the leaves increased significantly when the mixture of both ions was applied.
