Sure, here is an article on Paddy fertilizer management at heading stage:
Paddy fertilizer management is crucial in ensuring a good yield of rice crops. During the heading stage, which is the time when the panicles begin to emerge from the rice plant, proper application of fertilizer is important in providing the necessary nutrients for the plant to grow healthy and strong. In this stage, the plant requires sufficient nitrogen, phosphorus, and potassium.
Nitrogen is the most important nutrient needed by the rice plant during the heading stage. It helps in the development of strong stems and healthy leaves and is essential for the production of rice grains. During this stage, farmers should apply 60-70% of the total nitrogen requirement of the plant. Applying nitrogen at the wrong time, especially too late or too early, can cause negative effects on the growth and development of the plant.
Phosphorus is also vital during the heading stage as it helps in root development, flowering, and seed development. Farmers should apply phosphorus before planting the rice crop or at the early stage before the heading stage. At the heading stage, farmers can apply a small amount of phosphorus fertilizer, which is used for the growth of the panicle and the establishment of the panicle’s branches.
Potassium is essential for the formation of rice grain, improving the quality, and increasing the yield. Farmers should apply potassium fertilizer before the planting of the rice crop or at the early stage. At heading stage, the plant requires more potassium because the panicle is growing and needs to form the grains.
In conclusion, proper fertilizer management during the heading stage is necessary for rice crops to have a good yield. Farmers should apply nitrogen, phosphorus, and potassium fertilizers in the correct proportions and at the right time for the crops to have healthy growth, strong stems, develop rice grains, and increase quality yield. They should also consult agronomists and experts for advice on the application of fertilizers to achieve maximum output.
