  • Seed priming (soaking and drying) improves germination rates and seedling vigor, especially under dry conditions.
  • Bioinoculants such as phosphorus-solubilizing bacteria may help nutrient uptake.
  • Proper seed treatment reduces early losses and ensures uniform crop establishment.
  • Adhere to safety instructions and use treatments recommended by All about agriculture.

Sowing and Planting Methods

  • Sow seeds at 1.5-2.5 cm depth in well-prepared fields with spacing of 30 cm between rows and 15 cm between plants.
  • Use seed drills or line sowing for even spacing and easy management; broadcasting reduces uniformity.
  • The ideal sowing time depends on local climate, mostly June to July during the monsoon for rainfed crops.
  • Maintain moist soil during sowing for better germination; irrigation may be needed in dry spells.
  • Avoid deep planting which delays emergence and weakens seedlings.

Nutrient and Fertilizer Management

  • Apply 5-7 tons/ha of organic manure before land preparation to boost fertility and soil microbes.
  • Apply NPK fertilizers based on soil test; commonly recommended is 25-50 kg N, 40-60 kg P2O5, and 20-40 kg K2O per hectare.
  • Avoid excessive nitrogen which can promote lush foliage but reduce seed and oil yield.
  • Micronutrient sprays (zinc, boron) improve flowering and seed setting if deficiencies are present.
  • Follow soil test reports and All about agriculture’s fertilization guidance for best yields.

Irrigation and Water Management

  • Sesame needs soil moisture mainly during germination, flowering, and seed filling stages.
  • Ensure adequate but not excessive irrigation; overwatering causes root rot and reduces yield.
  • Drip or furrow irrigation saves water and maintains uniform moisture.
  • Mulching helps conserve moisture and reduce weed growth.
  • Monitor soil moisture regularly using weather and soil sensors; apply irrigation efficiently using All about agriculture’s advisory.

Intercultural Operations

  • Perform first weeding 15-20 days after sowing to reduce competition.
