ਕਣਕ ਦੇ ਦਾਣਿਆਂ ਵਿੱਚ ਜਿੰਕ ਵਧਾਉਣ ਦਾ ਚੰਗਾ ਮੌਕਾ wheat grain fortified with zinc

#wheat #crop #pau #seed #zinc zinc in the grain is best achieved through agronomic biofortification, primarily using foliar application of zinc sulfate (  ZnSO4⋅7H2OZnSO sub 4 center dot 7 H sub 2 O ZnSO4⋅7H2O ) during the booting to milk stages. This method is more effective than soil application alone, often combined with soil, urea, or fungicide applications for maximum, bioavailable Zncap Z n 𝑍𝑛 concentration in the grain.  Key Methods for Zinc Fortification in Wheat Grain  Foliar Application (Most Effective): Spraying at the late boot, heading, or milk stages directly onto the foliage is the most efficient method. This approach directly increases 𝑍𝑛 concentration in the grain, with higher effectiveness than soil applications alone. Combined Application: For maximum, long-term impact, a combination of soil application ( 50 kg ZnSO4⋅7H2O ha-150 kg ZnSO sub 4 center dot 7 H sub 2 O ha to the negative 1 power 50 kg ZnSO4⋅7H2O ha−1 before sowing) and foliar application (at heading/milk stage) is recommended. Timing and Formulation: The best time for foliar application is the late afternoon, ensuring leaves are thoroughly wetted. ZnSO4⋅7H2OZnSO sub 4 center dot 7 H sub 2 O ZnSO4⋅7H2O is often considered cost-effective compared to other sources. Soil Application: Genetic Biofortification: Developing or using high-zinc wheat varieties in conjunction with agronomic practices ensures higher. Zinc is an essential micronutrient for plants, animals, and humans, acting as a crucial cofactor for hundreds of enzymes, facilitating DNA synthesis, gene expression, and immune function. In plants, it drives photosynthesis, chlorophyll formation, and growth regulation. In humans and animals, it is vital for metabolism, immune system support, and cell division. Role of Zinc in Plants Enzyme Activation & Metabolism: Zinc is crucial for the function of over 300 enzymes, playing a key role in energy transfer, nitrogen metabolism, and photosynthesis. Growth and Development: It is essential for producing auxin, a hormone regulating stem elongation and overall growth. Chlorophyll Formation: Zinc is necessary for chlorophyll production and maintaining photosynthesis efficiency. Reproduction & Defense: It helps in pollen tube formation, seed production, and strengthens cell membranes to fight disease and pathogen attacks. Role of Zinc in Humans and Animals Immune System Strength: Zinc is fundamental for immune cell development and function. Protein and DNA Synthesis: It is required for DNA/RNA replication and protein synthesis, influencing cell division and tissue repair. Metabolic Function: It regulates enzyme activity, including those involved in Vitamin A and E metabolism. Growth and Reproduction: It is essential for sexual maturity, reproduction, and overall growth. Deficiency Effects: A lack of zinc causes skin disorders, hair loss, slowed wound healing, and impaired immune function. Impact on Health and Agriculture Dietary Deficiency: Approximately 30% of the global population does not get enough zinc, often due to consumption of cereal-based foods grown in zinc-deficient soil. Soil Management: Over 50% of Indian soils are deficient in zinc, directly impacting crop productivity and human nutrition. Crop Yields: Adequate zinc increases plant resistance to pathogens and improves crop yield. Zinc is not redox-active, allowing it to act in biological systems without causing oxidative damage, distinguishing it from other trace elements like iron or copper.
