“…Zinc and iron deficiencies are well-documented public health issue and an important soil constraint to crop production. Generally, there is a close geographical overlap between soil deficiencies and human deficiencies of Zn and Fe, indicating a high requirement for increasing concentrations of these nutrients in food crops [10]. Zinc and iron plays significant role in various enzymatic and physiological activities of the plant.…”

The experiment was conducted at Agricultural Research Station (ARS), Hagari of Northern dry zone of Karnataka for the two consecutive years 2021-2022 to study the effect of graded levels of nitrogen with iron and zinc nutrition on growth, yield and quality of Pearl Millet. The experiment consists of nine treatments replicated thrice in randomized complete block design (RCBD).The results showed that application of 100 % Recommended dose of nitrogen (RDN) + Foliar spray of ZnSO4.7H2O + FeSO4.7H2Oat0.5 % each at 30 and 45 days after sowing has recorded higher growth parameters viz., plant height (199.4.cm), number of leaves (18.6), leaf area (3160.7 cm2), leaf area index (4.73) and total dry matter production (259.96 g plant-1) at harvest stage. The yield parameters such as weight of ear head (53.13 g plant-1), grain weight (46.11 g plant-1), test weight (21.84 g), grain yield (1739 kg ha-1), stover yield (2900 kg ha-1) and harvest index (37.48 %) recorded significantly higher in treatment T9 consists of 100 % RDN + Foliar spray of ZnSO4.7H2O + FeSO4.7H2Oat0.5 % each at 30 and 45 days after sowing. The quality parameters like, protein content (19.62 %) and protein yield (341.0 kg ha-1) recorded significantly higher in the same treatment. Thus, application of recommended dose of fertilizer along with foliar spray of zinc and iron enhances the growth, yield and quality of pearlmillet.

Context Maintaining food and nutritional security for the ever increasing population of the world is a great chllenge. Zinc and iron are important micronutrients for both human health and plant growth. Insufficient intake of these micronutrients leads to their deficiency in human body which causes morbidity and mortality in different age groups of poor populations in developing countries. Aims Therefore, agronomic biofortification is considered the most promising approach to alleviate zinc and iron malnutrition in developing countries. Methods The studies reviewed in this article clearly show that the combined application of zinc and nitrogen, iron and nitrogen, and zinc, iron and nitrogen to the soil or to the foliage during the reproductive phase leads to enhanced nutrient (zinc and iron) content in edible parts of crop plants. This happens as the remobilisation and translocation of zinc, iron and urea are governed by the same genetic pathways inside the plant. Key results The soil/foliar application of micronutrients (zinc and iron) along with nitrogen (mainly through urea) improves not only the micronutrient (zinc and iron) content in edible parts of the crop plants but also the crop productivity, and thus, is a win–win situation for growers as well as consumers. Conclusions Foliar application of urea at 1–2% along with zinc or iron or both during the reproductive phase has been found more effective for biofortification point of view. Implications This article reviews the effects of zinc and iron application in combination with nitrogen on agronomic biofortification in important field crops.
