Green gram, also known as moong, is an important pulse crop grown widely across India. Proper nutrient management in green gram is essential for good plant growth, higher yield, and better grain quality. Many farmers believe pulses do not need much fertilizer, but balanced nutrition is still necessary, especially during early growth and flowering stages. Managing nutrients correctly also improves soil fertility and benefits the next crop.
The first step in nutrient management is soil preparation and soil health. Green gram grows best in well-drained, fertile soil. Before sowing, fields should be well prepared and free from weeds. Adding well-decomposed farmyard manure or compost during land preparation improves soil structure and provides slow-release nutrients. Organic matter also supports beneficial soil microbes.
Green gram, like other pulse crops, has the ability to fix nitrogen from the air through root nodules. However, this process starts only after the plant is well established. Therefore, a small starter dose of nitrogen is useful during early growth. This helps seedlings grow faster until nitrogen fixation begins. Excess nitrogen should be avoided because it reduces nodulation and increases vegetative growth instead of pods.
Phosphorus is one of the most important nutrients for green gram. It supports root development, early plant growth, flowering, and pod formation. Phosphorus deficiency results in poor root growth and fewer pods. Applying phosphorus at sowing helps plants establish well and improves yield.
Potassium helps improve plant strength, disease resistance, and tolerance to stress conditions like drought. It also supports better grain filling. Although green gram does not require large amounts of potassium, deficiency can reduce yield and seed quality. Potassium should be applied based on soil condition.
Sulphur is an important nutrient for pulse crops. It plays a key role in protein formation and nodulation. Sulphur deficiency is common in many Indian soils and results in yellowing of young leaves and poor growth. Applying sulphur improves plant health and yield.
Micronutrients, especially zinc, boron, and molybdenum, are very important for green gram. Zinc deficiency causes stunted growth and yellowing, while boron deficiency affects flowering and pod development. Molybdenum helps in nitrogen fixation. If deficiency symptoms appear, corrective measures should be taken.
Seed treatment with beneficial bacteria improves nutrient uptake. Treating seeds with Rhizobium culture helps increase nitrogen fixation. Phosphate-solubilizing bacteria help make soil phosphorus available to plants. Seed treatment should be done carefully and seeds should be sown on the same day.
Timing of fertilizer application is very important. Most nutrients should be applied as a basal dose at sowing so that plants can access them during early growth. Top dressing should be minimal and only if deficiency symptoms appear.
Irrigation management supports nutrient uptake. Green gram does not tolerate waterlogging, which reduces nutrient absorption and root health. Light and timely irrigation at critical stages such as flowering and pod formation improves nutrient efficiency.
Regular field monitoring helps identify nutrient-related problems early. Yellowing, slow growth, or poor pod formation should be corrected promptly.
In conclusion, nutrient management in green gram should focus on balanced and need-based application. Use of organic manure, small starter nitrogen dose, adequate phosphorus, potassium, sulphur, and micronutrients, along with seed treatment and proper irrigation, helps achieve healthy crop growth. Proper nutrient management not only increases green gram yield but also improves soil fertility and supports sustainable farming practices.
