Essential micronutrient required

This element can be toxic under high concentrations (Nan et al., 2002). Zn being an essential micronutrient taken active part in metabolic activities of plants and is directly or indirectly required by several enzymatic systems auxin, protein synthesis, seed production, and rate of maturity.

Sexual reproduction in plant is more sensitive to low B, than vegetative growth. Boron needed for growth of the pollen tube during flower pollination and therefore important for good seed set and fruit development. Boron is thought to increase nectar production by flowers, and this attracts pollinating insects. B in crop production is one of the essential micronutrient required for normal growth of most of the crops.

Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants. The requirement of micronutrients (boron, iron, copper, zinc, manganese, magnesium and molybdenum) is only in traces, which is partly met from the soil or through chemical fertilizer or through other sources.

Plant nutrition plays a major role in quantitative and qualitative crop production in bringing sustainability and plants require seventeen essential elements for their normal growth and development. Among these, those elements required smaller in quantity is called micronutrients (Fe, Cu, Zn, Mn, B, Cl, Mo and Ni). Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants.

Inadequate and inappropriate complementary feeding are major factors contributing to excess morbidity and mortality in young children in low resource settings. Animal source foods in particular are cited as essential to achieve micronutrient requirements.

Phosphorus and micronutrients (zinc, copper, iron and manganese) are the essential nutrients which are required for normal plant growth. Phosphorus and all micronutrient cations are mutually antagonistic in certain circumstances which can cause yield reductions in many crops due to their deficiencies. Deficiencies typically happen when a nutrient is available in small amounts.

Zinc (Zn) is one of the most essential micronutrients required for normal plant growth and development. Even though considerable quantity of inorganic Zn is applied in soil but significant quantity of it gets converted into unavailable forms. Zn solubilising microorganisms are the potential substitute for Zn supplement to plant from soil. Among the four isolates that were screened for Zn solubilization, fungal ones performed better than bacterial ones and Aspergillus sp. in particular, outperformed every other isolate in the test. It produced a clear halo zone of 22.

Essential micronutrients are important for maintenance of life. Deficiency of micronutrients is more likely to be encountered in children, and women studies are required to investigate the status of micronutrients in children and women.

Micronutrients (or ‘trace elements’) are required in animal diets for health and welfare, and therefore they are essential for the agricultural production of milk, meat, fibre, and eggs.

There is broad agreement on what must be included in a package of key, low-cost interventions – from vaccines and medicines to family planning and micronutrients – that can mean the difference between life and death for many vulnerable women and children. In order to deliver this essential package of interventions and ensure that countries are able to sustain their efforts over the longer term, scaled-up investment in health systems is also critical. Strong health systems require sustained investment over time.

A plant nutrient is a chemical element that is essential for plant growth and reproduction. Essential element is a term often used to identify a plant nutrient. The term nutrient implies essentiality, so it is redundant to call these elements essential nutrients. Commonly, for an element to be a nutrient, it must fit certain criteria. The principal criterion is that the element must be required for a plant to complete its life cycle. The second criterion is that no other element substitutes fully for the element being considered as a nutrient.

8 Boron Boron (B) is one of the eight essential micronutrients, also called trace elements, required for the normal growth of most plants. It is the only nonmetal among the plant micronutrients. Boron was first recognized as an essential element for plants early in the twentieth century
