Sure, I can give you an article on groundnut fertilizer information at 45 DAS.
Groundnut is an important legume crop grown mainly for oil and protein-rich seeds. In order to boost the yield and quality of your groundnut crop, proper use of fertilizers during the growing period is important. At the 45th day after sowing (DAS), the plants are at their vegetative stage and require specific nutrients that are essential for their growth and development. Let’s take a look at the required fertilizers and their importance at this stage.
Nitrogen (N)
Nitrogen is an important nutrient needed by any plant to survive and grow. At 45 DAS, groundnut plants need adequate nitrogen for their vegetative growth and development. Nitrogen helps in the production of chlorophyll, the green pigment found in leaves that help in photosynthesis. At this stage, it is recommended to apply nitrogen fertilizers such as urea at a rate of 25-30 kilograms per hectare.
Phosphorus (P)
Phosphorus is another essential nutrient required by groundnut plants at the vegetative stage, especially during root development. It helps in the rapid growth of roots, which increases water uptake by the plant. Phosphorus is also important in the transfer and storage of energy in the plant. At 45 DAS, groundnuts require phosphorus fertilizers such as triple superphosphate at a rate of 50-60 kilograms per hectare.
Potassium (K)
Potassium is essential for groundnut growth, development, and yield. It helps in regulating water movement in the plant, which is important for maintaining turgor pressure in cells for proper growth. It also helps in the formation of high-quality kernels in the groundnut, which results in higher yields. At 45 DAS, potassium is required at a rate of 25-30 kilograms per hectare.
Sulphur (S)
Sulphur is an important nutrient needed by legume crops such as groundnuts. It plays a major role in protein synthesis, which is important for producing high-quality seeds in groundnut plants. It also enhances the utilization of nitrogen in the plant. At 45 DAS, it is recommended to apply sulphur fertilizers such as gypsum at a rate of 25-30 kilograms per hectare.
In conclusion, proper use of fertilizers during the growing period is important for the high yield and quality of groundnut crops. At 45 DAS, groundnut plants require nitrogen, phosphorus, potassium, and sulphur nutrients to support their vegetative growth and development. Farmers should apply the recommended fertilizers at the appropriate rates to ensure that the crop is well-nourished and healthy.
