As an AI language model, I can provide an article on fertilizer dose in wheat, especially at sowing time.
Wheat is a major staple crop globally that is used as a source of food, beverage, and industrial raw material. To achieve a good yield and quality, wheat requires essential macronutrients such as nitrogen, phosphorus, and potassium. After determining the soil nutrient status, the next step would be to apply the appropriate amount of fertilizers at the sowing time. Here is an article on fertilizer dose in wheat, especially at sowing time:
Fertilizer dose in Wheat at sowing time
Wheat requires a specific combination of nutrient amounts that should be applied during the time of sowing. The essential macronutrients needed by wheat are nitrogen, phosphorus, and potassium. Here are some tips on how to make the right decisions regarding the application and dosage of fertilizers:
– Soil testing
Before applying any fertilizer, it is essential to determine the soil nutrient status. This is done through soil testing, which is important to make a precise fertilizer application. Inadequate nutrients or excesses can lead to yield reduction or nutrient leaching.
– Nitrogen (N) Fertilizers
Nitrogen is the most important nutrient to wheat yield as it is responsible for plant growth, development, and yield. Nitrogen should be applied at the time of wheat sowing. N fertilizers can be applied as a basal dose at the beginning of sowing or as a split application divided into two or three portions. Nitrogen fertilizers such as urea or ammonium sulfate can be applied at a rate of 100-120kg/ha.
– Phosphorus (P) Fertilizers
Phosphorus fertilizers are key to wheat development in its early stages. It plays a vital role in root formation, greater yield, and robust plant growth. Phosphorus should be applied at the time of sowing as a basal dose. Rock phosphate, SSP, or DAP are the common phosphorus fertilizers used for wheat. The recommended application rates range between 50-60kg/ha.
– Potassium (K) Fertilizers
Potassium is important for regulating plant growth, improving drought tolerance, and increasing yield. It also plays a pivotal role in enhancing wheat quality. Potassium fertilizers like muriate of potash should be applied at the time of sowing as a basal dose. The application rate for potassium fertilizers is around 30-40kg/ha.
In summary, fertilizer dose in wheat at sowing time should be based on soil testing to determine the nutrient status. Nitrogen should be applied as a basal dose or split into two or three portions to ensure better growth, development, and yield. Phosphorus is essential for early crop development, while potassium is necessary for growth regulation and improving drought tolerance. A balanced application of the essential nutrients will ensure a high yield and quality wheat crop.
