Impact of micronutrient seed priming on germination, growth, development, nutritional status and yield aspects of plants

The present review article is dealing with the potentiality of micronutrients in terms of seed priming treatment and its effect within the plant system is considered. Since last 3 to 4 decades various scientists are working with different planting methods and introduced several seed invigoration techniques, one of them is seed priming. Seed priming is basically a restricted hydration treatment with appropriate timing, in which seeds are treated with various types of organic and inorganic compounds. Whereas in this review, we have discussed the potential of different micronutrients in seed priming treatments for escalating crop growth, development and grain yield. Micronutrient priming has several beneficial effects in the morpho-physiological, biochemical and molecular aspects of the plants. In most cases, micronutrient application through seed treatment has astonishingly performed better than other application methods. Being an easy and cost effective method of micronutrient application, seed priming offer an attractive option for resource-poor farmers.
