Green gram, also known as moong, is an important pulse crop grown across India. It is valued for its short duration, high protein content, and ability to improve soil fertility. To get a good yield, farmers must ensure proper nutrient management, because moong is sensitive to nutrient deficiencies, especially during early growth. Balanced nutrition helps the crop grow faster, flower well, and produce healthy pods.
The first step in nutrient management is preparing the soil properly. Moong grows best in well-drained loamy soils rich in organic matter. Before sowing, farmers should add 2–3 tons of well-decomposed farmyard manure (FYM) or compost per acre. Organic matter improves soil structure, increases microbial activity, and helps roots grow deeper.
Green gram is a legume, which means it can fix atmospheric nitrogen through rhizobium bacteria in its root nodules. However, for good nodulation to occur, the crop needs support from the soil. Farmers should use seed inoculation with rhizobium culture before sowing. This ensures better nitrogen fixation and improves yield naturally.
Although moong fixes its own nitrogen, it still requires a small amount of nitrogen at sowing time. Usually, 8–10 kg nitrogen per acre is enough as a starter dose. This helps seedlings establish quickly and grow stronger during the early days.
Phosphorus is a very important nutrient for green gram. It supports root development, nodulation, and pod formation. Farmers should apply 16–20 kg P₂O₅ per acre at sowing. Phosphorus should be placed near the seed to help early root growth. Using Single Super Phosphate (SSP) is helpful because it provides both phosphorus and sulphur.
Potassium is needed in smaller amounts, but it strengthens the plant and improves resistance to drought and diseases. Farmers can apply 8–10 kg K₂O per acre if the soil is low in potassium. A soil test can guide the exact requirement.
Sulphur is another nutrient that plays an important role in pulses. It helps in protein formation and improves pod filling. Farmers can apply 8–10 kg sulphur per acre, often through SSP or gypsum. Sulphur deficiency reduces plant growth and seed quality.
Micronutrients also influence moong production. Zinc, molybdenum, and boron are commonly required. Zinc deficiency appears as small, pale leaves, while molybdenum improves nitrogen fixation. A light application of zinc sulphate or a foliar spray of micronutrient mixture can correct deficiencies.
Water management affects nutrient availability. Moong does not tolerate excess water, so fields should be well-drained. Light irrigation at flowering and pod formation stages helps improve nutrient uptake and seed development. Avoid waterlogging, as it damages nodules and reduces nitrogen fixation.
Weed control is also a part of nutrient management. Weeds compete with moong for nutrients, especially in the first 30 days. Keeping the field clean ensures that the crop receives maximum nutrients.
By using organic manure, starter nitrogen, balanced phosphorus and potassium, sulphur, micronutrients, and proper rhizobium inoculation, farmers can manage nutrients effectively in green gram. Good nutrient management not only improves yield but also enhances soil fertility, making moong a profitable and sustainable crop for farmers.
