Sure, here is an article on the dose of fertilizer in rice crops:
Fertilizers are essential for the growth and development of crops. The same goes for rice crops, which are a staple food for millions of people around the world. However, the application of fertilizers in rice crops should be done carefully, as the wrong dose or type of fertilizer can lead to negative consequences. In this article, we will discuss the dose of fertilizer in rice crops and its impact on crop yield.
Firstly, it is important to note that the dose of fertilizer required for rice crops depends on several factors like soil type, climate, growth stage of the crop, and the variety of rice being grown. Therefore, it is necessary to conduct a soil test before applying the fertilizer to determine the soil pH, nutrient availability, and other factors that affect crop growth. Based on the results of the soil test, calculate the amount of fertilizer required and choose the appropriate type of fertilizer.
In general, rice crops require three primary nutrients, namely, nitrogen (N), phosphorus (P), and potassium (K). The dose of fertilizer for rice crops varies depending on the stage of growth of the crop and the nutrient requirement of the variety being grown. For example, during the vegetative stage, rice crops require a higher dose of nitrogen fertilizer compared to the other stages.
In the case of paddy rice, the recommended dose of fertilizer for NPK per hectare is 120-150 kg of Nitrogen, 30-60 kg of Phosphorus pentoxide, and 30-60 kgs of Potassium oxide. However, the dose of fertilizer may vary depending on the soil type and the variety of rice being grown.
It is also important to apply fertilizers at the right time. Applying fertilizers at the wrong time may lead to wastage of nutrients or even damage the crop. For instance, if nitrogen fertilizer is applied at the wrong time, it may lead to lodging of the crop, which can reduce the yield.
In conclusion, the dose of fertilizer in rice crops is critical for achieving optimal crop yields. It is advisable to conduct a soil test before applying the fertilizer, choose the appropriate type of fertilizer, apply it at the right time and dosage, and take other necessary precautions to prevent damage to the crop. Proper management of fertilizers can help improve crop yield and ensure food security for millions of people worldwide.
