Emerging Nutrient Deficiencies in Cereal Production System and their Possible Management Strategies to Achieve Nutritional Securities

Rye, oats, barley, corn, triticale, millet, and sorghum are among the cereals cultivated in various countries. With more than half of theworld’s grain production going to wheat and rice, these two crops are the most significant on the planet. Human have traditionallyconsumed cereals, which are staple foods and significant nutrient sources in both developed and developing nations. Cereal goodscontain a variety of micronutrients, including vitamin E, several B vitamins, magnesium, and zinc, and are a significant source of energy,carbohydrate, and protein. All living species, including crop plants, require a number of fundamental elements in order to maintaindevelopment and cell processes as well as to complete the life cycle. For the development and production of plants, vital minerals arenecessary. Essential minerals are indispensable for plant growth and production. There are a variety of recognized essential mineralelements that are mostly accumulated from the soil. However, the soils of the Indian subcontinent have been deficient in some nutrientsas a result of years of extensive agriculture and unbalanced fertilizer use. Under nitrogen (N), phosphorus (P), and potassium (K) nutrientstress, leaf characteristics show different deficiency symptoms, according to the plant nutrition process. For crop nutrient management,it is critical to develop a reliable, fast, and modified method for diagnosing crop nutrition. Improving fertilizer efficiency is a majorconcern for managing crop production and maintaining soil economic productivity.
