What is the recommended application rate of fertilizers in maize production?


  • The recommended application rate of fertilizers in maize production can vary depending on the soil fertility, previous crop history, and the nutrient needs of the specific maize variety being grown. However, a general guideline for fertilizer application in maize production is to apply nitrogen (N), phosphorus (P), and potassium (K) at a ratio of 2:1:1 or 3:1:1.

    For example, if you plan to apply 100 kg/ha of N, you should apply 50-33 kg/ha of P and 50-33 kg/ha of K. The actual amounts of fertilizers needed may vary depending on soil analysis, but a common recommendation is to apply 60-90 kg/ha of N, 30-45 kg/ha of P, and 30-45 kg/ha of K.

    It's important to note that excessive use of fertilizers can harm the environment and also increase production costs. Therefore, it's advisable to conduct soil tests to determine the actual nutrient requirements and consult with agricultural experts or extension officers for specific recommendations on fertilizer application.
