The total fertilizer dose required for P.R paddy crop largely depends on various factors such as soil fertility, weather conditions, type of paddy, and farming practices. To determine the fertilizer requirement for P.R paddy crop, soil analysis is the primary step that should be conducted. Soil testing helps in understanding the soil fertility status and its nutrient profile. Based on the soil test report, a balanced supply of fertilizers can be calculated and tailored for the P.R paddy crop.
In general, P.R paddy crop requires NPK fertilizers in the ratio of 4:2:1. The required fertilizer doses vary with respect to the paddy variety, growth stages, and yield targets. For example, for high-yielding P.R paddy variety, the recommended NPK fertilizers dosage per hectare are 120:60:40 kg, respectively.
Apart from NPK fertilizers, micronutrients such as Zinc, Iron, and Manganese are needed for better crop growth and yield. The essential dose for micronutrient fertilizers for P.R paddy crop is about 10 kg per hectare.
It is essential to note that excessive application of fertilizers leads to environmental degradation, soil acidity, and nutrient imbalance. Hence, adequate supply of fertilizers at the right time is essential for better crop yield and sustainable agriculture.
In conclusion, the total fertilizer dose required for P.R paddy crop depends on various factors and varies with respect to the crop variety, soil fertility status, and farming practices. Soil analysis and crop management practices such as appropriate fertilization techniques must be implemented to achieve the desired yield and enhance soil fertility.
