The Complete Guide to Green Gram (Moong)

Master the cultivation of this short-duration, nutrient-dense pulse crop.

Green Gram Field

Introduction to Green Gram

Green Gram, or Moong, is a fast-growing pulse crop (65-75 days) that is highly valued for its protein content and easy digestibility. It is an excellent choice for crop rotation and can be grown as a sole crop or intercrop.

Quick Harvest

Because of its short duration, Green Gram can be grown in between two main crops, helping farmers maximize field utility and income throughout the year.

Step 1: Soil Preparation & Sowing

Moong thrives in well-drained loamy to sandy loamy soils. Prepare the land by plowing twice and harrowing to get a fine seedbed.

Detailed Process:

  1. Land Tillage: Conduct 2 rounds of ploughing followed by harrowing to achieve a fine tilth.
  2. Variety Pick: Choose short-duration, high-yielding varieties like IPM 2-14 or WGG-42.
  3. Seed Rate Logic: Use 15-20 kg/ha for sole cropping and 8-10 kg/ha for intercropping.
  4. Precision Sowing: Maintain 30 cm between rows and 10 cm between plants.
  5. Pre-Sowing Treatment: treat seeds with fungicides and Rhizobium culture for better health and nitrogen fixation.

Step 2: Mosaic Virus Control

Yellow Mosaic Virus (YMV) is a major threat. Early detection and prevention are your best defense.

Detailed Process:

  1. Choose Resistance: Always select YMV-resistant or tolerant varieties as the primary defense.
  2. Vector Management: Control whiteflies, the primary carriers, using yellow sticky traps (10-12 per acre).
  3. Field Sanitation: Remove "volunteer" pulse plants from previous seasons that may harbor the virus.
  4. Infected Plant Removal: Roguing of early infected plants helps prevent the spread within the field.
  5. Botanical Sprays: Use neem-based sprays if whitefly populations begin to rise.

Step 3: Water Requirements

Green Gram is drought-tolerant but moisture is critical during reproductive phases.

Detailed Process:

  1. Critical Flowering Stage: Ensure the soil has enough moisture when the plants begin to bloom.
  2. Pod Formation Phase: Maintain moisture during pod development to ensure high-quality seeds.
  3. Supplemental Irrigation: provide 3-4 light irrigations for summer crops at 10-15 day intervals.
  4. Waterlogging Prevention: Ensure your field has good drainage; Moong is sensitive to standing water.

Step 4: Harvesting

Timely picking of pods is essential as green gram often matures non-uniformly.

Detailed Process:

  1. Maturity Identification: Harvest when 80% of pods turn black or dark brown.
  2. Staggered Picking: provide 2-3 rounds of manual picking if the crop matures unevenly for maximum quality.
  3. Sun Drying: Spread harvested pods or plants in the sun for 2-3 days on a clean surface.
  4. Threshing Technique: Use a mechanical thresher or hand-beating once the pods are fully brittle.
  5. Winnowing & Cleaning: remove chaff, dust, and any damaged seeds.
  6. Storage Conditioning: Dry seeds to 9-10% moisture content before bagging.
  7. Safe Storage: Use triple-layer bags or store in cool, dry bins to prevent bruchid infestation.

Pro Tip: Mosaic Virus Management

Yellow Mosaic Virus is a major threat. Select resistant varieties like IPM 02-3 or CO-8 and control whiteflies, which are the primary carriers of this disease, using organic or recommended methods.
