Farming green gram (mung bean) involves several steps to ensure a healthy and productive crop. Here’s a detailed guide:
### 1. **Climate and Soil Requirements**
   - **Climate**: Green gram thrives in warm, dry climates. Ideal temperature ranges from 25-35°C. It is a short-duration crop and can be grown in both Kharif (monsoon) and Rabi (winter) seasons.
   - **Soil**: Well-drained loamy or sandy loam soils with a pH between 6.5 to 7.5 are ideal. Avoid waterlogged areas.
### 2. **Land Preparation**
   - Plow the field 2-3 times to achieve a fine tilth.
   - Remove weeds and incorporate organic matter, such as compost or farmyard manure (5-10 tons/ha), to improve soil fertility.
### 3. **Seed Selection and Treatment**
   - Use certified seeds of high-yielding varieties resistant to pests and diseases.
   - Before sowing, treat seeds with a fungicide like Carbendazim or Thiram at 2g/kg of seed to prevent fungal infections.
   - Optionally, treat seeds with Rhizobium culture to enhance nitrogen fixation.
### 4. **Sowing**
   - **Time**: In Kharif season, sowing is done in June-July; for Rabi, it’s done in October-November.
   - **Method**: Sow seeds at a depth of 4-6 cm using line sowing, broadcasting, or seed drill methods.
   - **Spacing**: Maintain row-to-row spacing of 30-45 cm and plant-to-plant spacing of 10-15 cm. This allows enough space for plants to grow and facilitates easy intercultural operations.
### 5. **Irrigation**
   - Green gram requires minimal irrigation. Typically, 1-2 irrigations are sufficient in the case of inadequate rainfall.
   - **Critical stages**: Ensure the crop has adequate moisture during flowering and pod formation stages.
### 6. **Weed Management**
   - First weeding should be done 20-25 days after sowing, followed by a second weeding 40-45 days after sowing.
   - Mulching can also help in suppressing weed growth.
### 7. **Fertilization**
   - Apply a basal dose of 20-25 kg/ha Nitrogen (N), 40-50 kg/ha Phosphorus (P2O5), and 20 kg/ha Potassium (K2O).
   - Mung beans have the ability to fix atmospheric nitrogen through root nodules, so additional nitrogen fertilization may not be necessary if Rhizobium inoculation is done.
### 8. **Pest and Disease Management**
   - **Common Pests**: Aphids, thrips, pod borers, and whiteflies.
     - Control: Use neem-based pesticides or chemical insecticides like Imidacloprid if necessary.
   - **Common Diseases**: Powdery mildew, yellow mosaic virus, and root rot.
     - Control: Regular monitoring and use of resistant varieties can reduce disease incidence. Apply fungicides like Mancozeb for fungal diseases.
