1. Micronutrients & Its benefits Syed Saeed Ur Rehman Shah Rgional Business Manager Farmers Equity Pakistan Pvt. Ltd.

2. Essential Plant Nutrients Macronutrients Required in relatively large amounts. Micronutrients Required in small amounts. Minor or trace elements.

3. Macronutrients Fall into one of three categories: Non-Mineral Elements Primary Nutrients Secondary Nutrients

4. Non-Mineral Elements (C) Carbon (H) Hydrogen (O) Oxygen

5. Primary Nutrients (N) Nitrogen (P) Phosphorus (K) Potassium

6. Secondary Nutrients (Ca) Calcium (Mg) Magnesium (S) Sulfur

7. Macronutrients Macronutrients are needed in relatively large amounts by plants.

8. Micronutrients (Fe) Iron (Cu) Copper (Zn) Zinc (B) Boron (Mo) Molybdenum (Mn) Manganese (Cl) Chlorine

9. Micronutrients Macronutrients are needed in relatively small amounts by plants. They are usually supplied by fertilizers.

10. Why foliar nutrition Now !

11. Function & Deficiency Symptoms of Nutrients

14. What are the Primary Nutrientsneeded by all crops

15. Secondary Nutrients Neededby all Crops

16. What are the Primary Nutrientsneeded by all crops

17. Micronutrients Needed by all Crops

18. Cotton

19. Make a Preliminary Diagnosis • Discoloration • Nutrient deficiencies • Diseases • Herbicide or salt injury

22. Approximately 20% of seasonal needs should be supplied pre-bloom

23. Supply remainder of N should be supplied during boll development period

26. Functions of Phosphorus in Cotton Production Promotes early boll development and hastens maturity Essential for vigorous root and shoot growth Helps overcome the effects of compaction Increases water use efficiency A 2 bale crop can take up more than 50 lb P2O5/A

27. P deficient cotton Symptoms are not distinct in cotton, Stunting Dark leaves Flowering delayed Poor boll retention Premature leaf senescence

28. Potassium in Cotton Production Bolls are major sinks for K, uptake may peak at as much as 1-2 Kg K2O/A/day during boll development. About 70% of total uptake occurs after first bloom. Affects quality (micronaire, length, and strength) Increases water use efficiency Reduces the incidence and severity of wilt diseases A 2 bale crop will take-up about 80Kg K2O

30. Affects both yield and qualityLate season affects younger leaves

33. Micronutrient Deficiency Symptoms • Interveinal chlorosis in younger leaves • Zn deficiency can result in leathery, upturned leaves and bronzing

34. Zinc Deficiency in Cotton

35. Boron Deficiency Symptoms Short, thick stems tips. Young leaves of terminal buds are light green at base. Leaves become twisted & die.
