5. Cultivation Practices

Season:

  • Kharif Season: Jowar is primarily grown during the Kharif season, from June-July to October-November, using the monsoon rains. It can also be grown in some parts during the rabi season, especially with irrigation.

Land Preparation:

  • Land should be prepared by plowing, followed by harrowing and levelling to create a fine seedbed.
  • Fertilization: Based on soil testing, fertilizers should be applied in balanced amounts. Jowar requires nitrogen, phosphorus, and potassium to boost growth and yield. Organic fertilizers and green manuring practices are encouraged to enhance soil fertility.

Sowing:

  • Seed Rate: The recommended seed rate is 7–8 kg per hectare for rainfed areas and 6–7 kg per hectare for irrigated areas.
  • Spacing: The rows should be spaced around 45–60 cm apart, and seeds should be sown at a depth of 3–5 cm.
  • Sowing Method: Jowar can be sown using a seed drill or by broadcasting. In rainfed areas, broadcasting is common, while in irrigated fields, seed drills are used for better germination.

Irrigation:

  • Jowar is typically a rainfed crop and does not require frequent irrigation. However, in drought-prone areas or during dry spells, 2-3 irrigations can improve yields.
  • In the rabi season, irrigation is essential for optimum growth.

Weed Control:

  • Weeds can compete with Jowar, especially during the early growth stages. Weed control is essential through:
    • Pre-emergence herbicides like Pendimethalin or Atrazine.
