Sure, here’s an article on “Query on Fertilizer Management in Groundnut” –
Groundnut (Arachis hypogaea L.) also known as peanut, is one of the most important oilseed crops and has a high nutritional value. It is grown around the world in different agroclimatic regions, particularly in India, China, and the United States.
Fertilizer management plays a significant role in the successful cultivation of groundnut. Proper application of fertilizers can enhance the yield and quality of groundnut, while incorrect or inadequate application can adversely affect the crop growth and yield. Here are some frequently asked queries on fertilizer management in groundnut:
1. What are the essential nutrients required for groundnut cultivation?
Groundnut plants require thirteen essential nutrients for growth and development. Among them, nitrogen (N), phosphorus (P), and potassium (K) are the most important macronutrients. Groundnut plants also require secondary macronutrients like calcium (Ca), magnesium (Mg), and sulfur (S) in lesser quantities, and micronutrients like iron (Fe), zinc (Zn), boron (B), manganese (Mn), copper (Cu), molybdenum (Mo), and chlorine (Cl) in trace amounts.
2. What is the fertilization schedule for groundnut?
The fertilization schedule for groundnut depends on the soil type, stage of growth, and nutrient requirements of the crop. Generally, the first application of fertilizers should be done at the time of sowing or planting, and subsequent applications should be done during the vegetative and reproductive stages of the crop. The recommended dose of NPK fertilizer for groundnut is 40-60-20 kg/ha.
3. What is the role of nitrogen in groundnut cultivation?
Nitrogen is an essential macronutrient required by groundnut plants for the synthesis of proteins, amino acids, and chlorophyll. Nitrogen also improves the quality and size of the groundnut kernels. However, excessive application of nitrogen can lead to vegetative growth at the cost of flower and pod formation, resulting in poor yield and quality.
4. Which is the best source of phosphorus for groundnut?
The best source of phosphorus for groundnut is diammonium phosphate (DAP) or single superphosphate (SSP). Phosphorus plays a crucial role in the root and shoot development of groundnut plants, and also enhances the uptake of other nutrients like nitrogen and potassium.
5. What is the importance of potassium in groundnut cultivation?
Potassium is an essential macronutrient required by groundnut plants for water regulation, disease resistance, and carbohydrate metabolism. It also enhances the quality and size of groundnut pods and kernels, and improves the shelf life of the harvested crop.
In conclusion, proper fertilizer management is crucial for the successful cultivation of groundnut. Farmers should follow the recommended fertilization schedule and choose the right source of nutrients to ensure optimal crop growth and yield. They should also monitor the soil fertility levels and adjust the fertilizer application accordingly.
