5. Cultivation Practices

Season:

  • Bajra is mainly a Kharif crop, sown during the monsoon season from June-July and harvested in September-November. It can also be grown in some regions during the rabi season with irrigation.

Land Preparation:

  • The field is usually plowed two to three times to ensure proper soil aeration and removal of weeds.
  • Leveling is done to ensure uniform water distribution during irrigation.

Sowing:

  • Seed Rate: The typical seed rate for Bajra is 6-8 kg per hectare for hybrid varieties. It is 8-12 kg per hectare for open-pollinated varieties.
  • Spacing:
    • Row-to-row spacing: 60–75 cm
    • Plant-to-plant spacing: 20–25 cm
  • Depth: Seeds are sown at a depth of 3–5 cm in the soil.
  • Sowing Method: Bajra can be sown using a seed drill for proper seed placement. In some regions, it can be broadcasted manually.

Irrigation:

  • Bajra is primarily a rainfed crop, but 2-3 irrigations during dry spells can significantly improve yields.
  • Irrigation should be applied at critical stages such as:
    • Pre-flowering: To ensure good vegetative growth.
    • Flowering and grain-filling: To avoid moisture stress.

Weed and Pest Management:

  • Weed Control: Weeds can be controlled using pre-emergence herbicides such as Atrazine and Alachlor. Manual weeding is also common.
  • Pest Control:
    • Shoot Fly: A major pest that affects young plants. Cultural practices like timely sowing and field sanitation can help control it.
    • Stem Borer: A serious pest, which damages the plant’s stems and reduces yield. Farmers can use pesticides like quinalphos to manage it.
    • Grasshoppers and Aphids: Insects that feed on Bajra leaves and stems. Regular monitoring and pesticide application are important.
  • Diseases:
    • Downy Mildew: A fungal disease that affects the plant’s leaves and reduces yield. Use of resistant varieties and fungicides like Carbendazim can help control it.
    • Rust: A fungal disease that causes yellow-orange spots on the leaves, leading to a reduction in photosynthesis.

6. Harvesting and Yield

Harvesting:

  • Bajra is usually harvested when the grains are mature, and the leaves turn yellow or brown.
  • The panicles (flower clusters) should be fully mature, and the grains should be hard.
  • Manual harvesting is typically done using sickles, although mechanized harvesters are also becoming common in larger farms.

Yield:

  • The average yield of Bajra in India ranges from 800 to 1,500 kg per hectare in rainfed conditions.
