Abstract:
Cultivation of cereals done in large scale which leads to depletion of the nutrients from soil. Application of nutrients to the soil would not be always an efficient way solely as this method does not deliver the nutrients efficiently from soil to the plants due to impact of many physicochemical attributes of soil like organic matter levels, pH of the soil, soil compaction, soil temperature, texture, poor aeration and nutrient deficiencies etc. Lower nutrient use efficiency, higher input costs, poor quality produce and decline in the yields triggers global food shortages. The solution to surmount these issues would be the supplementary foliar nutrition. Though soil fertilization methods are very common, foliar nutrition methods are more effective as well as economical under certain circumstances. Foliar fertilization is more crucial as it enables quick and easy penetration and absorption of nutrients into the plants. Foliar nutrition mainly used for supplementing the nutrient doses. Supplementary foliar nutrition during the crop growth triggers mineral levels in plants and enhances the crop yields. Keeping all these facts in view, significance of foliar nutrition, impacts of foliar nutrition of macronutrients and micronutrients on cereal crops, appropriate source and timings as well as advantages and disadvantages of foliar nutrition were discussed in this paper.
