Green gram (moong) is a short-duration pulse crop, but good nutrient management is still very important for getting more pods, better grain filling, and higher profit. Many farmers think pulses do not need fertilizers because they fix nitrogen from the air. It is true that green gram can fix nitrogen, but this happens properly only when the crop has healthy roots and effective nodules. If the soil is poor or the crop is stressed, nodules will be less and yield will suffer. So balanced nutrition, along with good soil health, is the best approach.
Start with soil preparation and organic matter. Green gram grows well in well-drained soil with good tilth. Adding well-decomposed farmyard manure or compost before sowing improves soil structure and moisture holding. Organic matter also supports beneficial microbes and helps the roots form nodules easily. Avoid using fresh, half-rotten manure, because it can increase pests and diseases.
Seed treatment is a very important best practice. Treat the seed with a suitable Rhizobium culture (and sometimes PSB culture) to improve nodulation and nitrogen fixation. This small step often gives a big benefit, especially in fields where green gram has not been grown recently. Seed treatment should be done in shade and seeds should be sown soon after treatment. If you also use fungicide treatment, follow the correct order and gap so the bio-culture is not harmed.
Even though green gram fixes nitrogen, a small starter dose of nitrogen is useful in the early stage. The crop needs nitrogen before nodules become active. This starter nitrogen supports early growth and helps the plant develop more branches. Along with nitrogen, phosphorus is very important in pulses. Phosphorus improves root growth, nodulation, and flowering. If phosphorus is low, plants remain weak and pod number reduces. Potassium also supports plant strength, drought tolerance, and grain filling, especially in lighter soils.
Apply fertilizers as basal at sowing so the young roots can access them early. Split application is usually not needed in green gram because the crop duration is short. However, in very light soils or under heavy rainfall, nutrient loss can happen, so farmers should keep an eye on crop growth and correct deficiencies quickly.
Sulphur is another key nutrient for pulses. Many Indian soils are becoming low in sulphur due to reduced organic manure use. Sulphur improves protein formation and helps better pod development. If sulphur is deficient, plants may look pale and yield reduces. Using a sulphur source along with fertilizers often improves moong yield and grain quality.
Micronutrients should not be ignored. Zinc deficiency is common in many areas and leads to stunted growth and poor flowering. Iron deficiency may appear in alkaline soils as yellowing of young leaves. Boron deficiency can affect flower and pod setting. If the crop shows clear symptoms, foliar spray is the fastest way to correct micronutrients. But for long-term improvement, soil application and organic matter addition are better.
Water and nutrient management go together. Green gram is sensitive to waterlogging, and waterlogged fields reduce nodulation and nutrient uptake. Ensure good drainage. In summer moong or in dry spells, one or two timely irrigations at flowering and pod filling can increase yield significantly. Avoid excessive irrigation, as it increases disease risk and reduces root health.
Another best practice is balanced use of fertilizers. Too much nitrogen is not good in pulses. It promotes leafy growth but reduces nodulation and can increase pests. Keep nitrogen low and focus on phosphorus, sulphur, and micronutrients. Also, maintain proper plant spacing and keep the field weed-free in the first 25–30 days, because weeds compete strongly and reduce nutrient availability to the crop.
In simple words, the best nutrient management in green gram includes adding organic manure, seed treatment with Rhizobium, giving a small starter nitrogen, ensuring enough phosphorus and sulphur, correcting micronutrients when needed, and maintaining proper moisture and drainage. With these practices, green gram plants become healthier, form more nodules, produce more pods, and give better yield and grain quality.
