Zinc Use in Rice Crop | When, Why, How and Dose required | Cyber Agri Extension |

Use of Zinc in Rice Crop Zinc (Zn) is a critical micronutrient in rice production, especially under flooded paddy conditions where its availability often declines. Its timely application ensures healthy early growth, improved tillering, strong root development, and better grain yield. ✅ Why Zinc is Important in Rice Enhances enzyme activity and chlorophyll formation Promotes tiller initiation and growth Prevents Khaira disease (Zn deficiency) Improves root development and water uptake Boosts grain size and yield ⚠️ Zinc Deficiency Symptoms in Rice Stunted growth in early stages Pale brown/bronze discoloration (Khaira disease) Reduced tiller number Poor root development 📋 Zinc Application Methods in Rice Method Material Dose per Acre Time of Application Soil Application Zinc Sulfate (ZnSO₄·7H₂O) 8–12 kg Basal (before or at transplanting) Foliar Spray Zinc Sulfate + Slaked Lime 0.5% ZnSO₄ + 0.25% Lime in 100 L water 2–3 sprays at 15-day intervals, starting 20 DAT Seedling Root Dipping Zn solution 2% ZnSO₄ solution dip for 15–20 minutes Before transplanting 📌 Best Practices Use chelated zinc (EDTA-Zn) in alkaline or saline soils. Do not mix zinc sulfate directly with phosphate fertilizers. Apply lime with foliar Zn to prevent leaf burn. 🌱 Recommended Timing Basal application before or during transplanting. Foliar spray during early tillering (20–35 DAT) and again at 45 DAT if needed. 📉 Zinc Deficiency Causes High pH (alkaline) soils Poor drainage or prolonged waterlogging Continuous use of Zn-free fertilizers 📌 Summary Hashtags #zincinrice #ricemicronutrients #khairadisease #zincsulfate #tilleringinrice #ricecropmanagement #balancedfertilization Forms of Zinc, Importance & Usage in Field Crops Forms of Zinc Used in Agriculture Zinc is available in different forms for agricultural use, including: Inorganic Zinc Fertilizers Zinc Sulfate (ZnSO₄) – Most commonly used form; available in monohydrate (ZnSO₄·H₂O, 33% Zn) and heptahydrate (ZnSO₄·7H₂O, 22% Zn). Zinc Oxide (ZnO) – Less soluble but effective in alkaline soils. Zinc Chloride (ZnCl₂) – Water-soluble but less commonly used. Chelated Zinc Fertilizers Zn-EDTA (Ethylenediaminetetraacetic acid) – Highly effective for foliar application and soil application. Zn-DTPA & Zn-HEDTA – Suitable for high-pH soils. Organic & Natural Zinc Sources Zinc-enriched manures and composts release zinc slowly into the soil. Zinc-coated fertilizers (e.g., zinc-coated urea) provide controlled zinc supply. Importance of Zinc in Field Crops ✅ Enzyme Activation – Essential for enzyme function in plants. ✅ Photosynthesis & Chlorophyll Production – Enhances plant growth and productivity. ✅ Protein & Hormone Synthesis – Helps in grain formation and plant maturity. ✅ Root Development & Stress Resistance – Strengthens root growth and improves drought tolerance. ✅ Increases Crop Yield & Quality – Prevents zinc deficiency, which leads to stunted growth and reduced productivity. Usage & Application Methods 🔹 Soil Application: Zinc sulfate (5-10 kg per acre) before sowing or at early growth stages. 🔹 Foliar Spray: 0.5% ZnSO₄ solution at vegetative and reproductive stages. 🔹 Seed Treatment: 0.2-0.5% ZnSO₄ solution for improved germination and early growth. 🔹 Fertigation: Chelated zinc (Zn-EDTA) for controlled release through drip irrigation. By using the right zinc form and application method, farmers can improve crop health, prevent zinc deficiency, and maximize yield in field crops like wheat, maize, rice, sugarcane, and legumes. #zincfertilizer #zincdeficiency #zincsulfate #chelatedzinc #cropnutrition #plantgrowth #soilhealth #micronutrients #fieldcrops #smartagriculture #highyieldfarming #sustainablefarming #foliarspray #seedtreatment #fertilizerapplication #rootdevelopment #photosynthesisboost #cropquality #nutrientmanagement #droughtresistance #cyberagriextension #cyber #agri #extension #ciber #sibr #agr Essential Forms of Zinc for Field Crops Zinc Fertilizers: Types & Benefits for Crops Importance of Zinc in Crop Growth & Yield How Zinc Deficiency Affects Field Crops Best Zinc Fertilizers for Maximum Crop Production Zinc Sulfate vs. Chelated Zinc: Which is Better?
