Title: Top Dressing Management for Paddy: Optimal Techniques at 25 & 45 Days
Introduction:
Top dressing is a crucial management practice in paddy cultivation aimed at supplementing the nutrient requirements of the crop during different growth stages. In this article, we will discuss the importance of top dressing and the optimal techniques for managing paddy crops at 25 and 45 days after sowing (das).
Importance of Top Dressing:
Top dressing plays a vital role in enhancing crop yield by replenishing essential nutrients required by paddy plants. These nutrients include nitrogen (N), phosphorus (P), and potassium (K), along with other secondary and micronutrients. Timely and proper top dressing ensures steady plant growth, improved crop health, and increased grain production.
Top Dressing at 25 Days:
At 25 das, paddy plants typically require an additional supply of nitrogen and phosphorus to sustain optimal growth. Farmers can utilize nitrogenous fertilizers, such as urea, to meet the nitrogen needs. Applying 40-50 kg of urea per hectare is recommended during this stage. Simultaneously, phosphatic fertilizers like diammonium phosphate (DAP) or triple superphosphate (TSP) can be applied at a rate of 20-30 kg per hectare.
Divide the required amount of fertilizer into two equal doses for uniform nutrient supply. Apply the first dose at 25 das and the second dose at 45 das. Ensure even distribution by broadcasting or placing the fertilizers in the soil near the root zone with appropriate precautions to avoid fertilizer burn on the leaves.
Top Dressing at 45 Days:
During this stage, paddy crops face an increased demand for nitrogen and potassium. Nitrogen is essential for plant growth and chlorophyll production, while potassium aids in grain filling and overall stress tolerance. Cultivators can incorporate ammonium sulfate (AS) or urea as a nitrogen source, applying 40-45 kg per hectare to meet crop requirements. Additionally, Muriate of Potash (MOP) or Sulphate of Potash (SOP) can be utilized as a potassium source, at a rate of 20-30 kg per hectare.
Follow similar techniques as mentioned earlier for even nutrient distribution during the application process. Uniformly spread the fertilizers and avoid excess concentrations in any specific area.
Conclusion:
Top dressing management is crucial for achieving optimal paddy crop growth and maximizing grain yield. Supplying the right nutrients at the correct stages of growth, such as at 25 and 45 das, ensures healthy plant development and higher productivity. Remember to divide the doses for uniform distribution and employ appropriate fertilizers based on nutrient requirements. By implementing efficient top dressing techniques, farmers can improve their paddy cultivation practices and reap the benefits of increased yields.
