“…Micronutrients can absorb and accumulate in plants by involving various mechanisms, which converse to more soluble ionic forms and are followed by specific/non-specific transporters (Pasala et al, 2022). The alteration of micronutrients is harmful to human health and the minerals deficiency causes yield reduction and improper plant growth.…”

In recent scenarios, the world’s food system is highly insecure and become a great challenge to the rapidly growing civilization. Agriculture is intricately tied to food security and life sustainability on earth. The arising climatic alteration forces plants to compete for nutrients from the soil. Crop yielding and their nutritional quality are highly influenced by environmental factors (biotic and abiotic stress), agronomic factors, pests and nutrient availability in the soil. These are the nanoparticle that monitors the elements in soil by sharing some signals. Micronutrients help to maximize plant growth and protect plants from diseases and pathogens. But the alteration of the environmental condition is highly responsible for nutrient limitation and growth inhibition. 35% of the world’s agricultural lands are decreasing their soil fertility, which leads to nutrient deficiency in plants. These insufficient nutrients of crops lower the yield and nutritional quality of food and affected human health. In the reproductive stage of plant growth, environmental stress is highly responsible for flower drop, pollen tube deformation, ovule abortion, pollen sterility and yield losses. A sufficient quantity of micronutrients can help to reduce the biotic and abiotic stress in agricultural crops. The current review gives a brief knowledge to understand the current features of micronutrients in the agricultural crop which focus on the mechanism, absorption activity, toxicity and deficiency of micronutrients in plants and how it secures our food system by increasing the yield and nutritional quality.

“…Manganese participates in the electron transport chain of photosynthesis and respiration, manganese inadequacy can cause reduced photosynthesis and poor nitrogen metabolism in rice. Magnesium is the central atom of the chlorophyll molecule and functions as a cofactor for multiple enzymes like phosphoenolpyruvate carboxylase, and ATPase [8], and Iron contributes to chlorophyll synthesis, despite not being part of its composition, iron forms part of proteins like cytochrome c, ferroxin [9], and Copper is a cofactor for several enzymes such as plastocyanin and superoxide dismutase, copper also contributes to lignin synthesis, pollen formation, and seed formation. Copper inadequacy can cause wilting and lower yields of rice [10,11].…”

The aim of this research was to identify the effects of NPS fertilizer with the spraying of Nano-NPK+TE and Cerium Oxide NPs on the active substances in rice grains, amber 33 cultivar. This field study was carried out in the Tali’a region, 41-Husainiya, Hilla city, Babylon province, Iraq, from 14/6/2022 to 25/11/2022, The study treatments were randomly distributed on the experimental units according to a simple and one-way experiment by a randomized complete block design (RCBD). The study treatments consisted of adding NPS fertilizer at four levels (0, 100, 200, and 300 kg ha-1) and spraying with nanomaterials of Nano-NPK+TE and Cerium Oxide NPs at concentrations of (2.5 ml L-1) and (50 mg L-1), respectively, with four sprays for each of them. A total of 16 experimental units were used. The Statistical analysis using the least significant difference test revealed that the process of fertilizing with NPS fertilizer and nanomaterials led to significant differences and an increase in the contents of volatile oils, saturated and unsaturated fatty acids among the dietary components of rice grains, so the findings from gas chromatography-mass spectrometry (GC-MS) analysis indicated that soil fertilization with NPS mineral fertilizer at level (300 kg ha-1) achieved the highest level of stearic acid content with a value of (9.460%), as well as the highest improvement in Palmitic acid content (24.240%) recorded by the treatment (NPS 100 kg ha-1). Moreover, the bi-combination of NPS (200 kg ha-1) + Spray CeO2 NPs gave the highest content of Oleic acid content in percentage (10.310%), and Linoleic, another type of unsaturated fatty acid, indicated a content of (10.020%) by the combination of (NPS (300 kg ha-1) + Spray nano-NPK+TE). Additionally, the highest percentage of Volatile oils showed at the foliar spraying combination (Spray nano-NPK+TE + CeO2 NPs), which gave a value of (46.50%).

“…Além disso, deve-se buscar alternativas capazes de potencializar o desenvolvimento da cultura, com o objetivo de obter folhas maiores, com maior vigor e _____________________________________________________________ Nesse contexto, o manejo da adubação pode contribuir para que esses objetivos possam ser alcançados(PASALA et al, 2022). A adubação foliar com micronutrientes melhorou o rendimento e a qualidade do alho(YADAV et al, 2018), enquanto o fornecimento de zinco aumentou a produtividade da cenoura e da alface (SONG; KIM, 2020), por exemplo.…”

A utilização de micronutrientes em hortaliças é uma prática que pode trazer resultados benéficos para a cultura. Muitas olerícolas da família Brassicaceae são exigentes em micronutrientes como o molibdênio e a utilização desse nutício é essencial para o desenvolvimento adequado da cultura. Todavia, há carência de recomendações adequadas desse micronutriente para o cultivo da rúcula (Eruca vesicaria ssp. sativa), em especial sobre a aplicação via foliar. Diante disso, esse trabalho teve como objetivo avaliar a influência do uso do molibdato de sódio, em aplicação via foliar, no crescimento de plantas de rúcula. A pesquisa foi realizada em ambiente aberto, onde plantas de rúcula foram cultivadas em recipientes plásticos. Foram avaliadas cinco doses de molibdado de sódio (0; 0,30; 0,45; 0,60 e 0,90 g L-1), aplicadas via foliar, em plantas de rúculas variedade Astro aos 19 dias após plantio. As doses de molibdato de sódio influenciaram o crescimento em altura, número de folhas, largura de folha, massa fresca e massa seca da rúcula. De maneira geral, para todas essas variáveis, houve máximo crescimento da planta com a aplicação da dose de 0,3 g L-1 de molibdato de sódio. Observou-se que a aplicação da dose de 0,90 g L-1 do adubo foliar reduziu fortemente o crescimento da rúcula e causou sintomas de intoxicação, caracterizados por alteração na coloração da haste para cor azul arroxeada, folhas flácidas e com aspecto opacos. Conclui-se que o fornecimento de molibdênio, via adubação foliar, melhora o crescimento de rúcula, apresentando-se como uma prática com potencial para ser adotada por produtores para aumentar o rendimento dessa cultura.
