Nutrient Management :: Sesame

Sesame (Sesamum indicum)

Application of Fertilizers

  • Spread FYM or composted coir pith or compost @ 12.5 t/ha evenly on the unploughed field and plough it in.
  • If the manure is not applied before commencement of ploughing, spread 12.5 t/ha of FYM or compost evenly on the field before the last ploughing and incorporate in the soil.
  • Apply NPK fertilizers as per soil test recommendation. If soil tests are not available, follow the blanket recommendations.

Rainfed:

  • Apply 23:13:13 kg NPK/ha or
  • 17:13:13 kg NPK/ ha + 3 packets of Azospirillum (600 g/ha) and 3 packets    (600 g/ha) of Phosphobacteria or
  • 6 packets of Azophos(1200 g/ha).

Irrigated:

  • Apply 35:23:23 kg NPK/ha or
  • 21:23:23 kg NPK/ha + 3 packets of Azospirillum (600 g/ha) and 3 packets (600 g/ha)  of Phosphobacteria or 6 packets of Azophos(1200 g/ha)
  • Apply full dose of N, P and K basally. Add 5 kg of Manganese sulphate per hectare. Apply 50% of the recommended P2O5and K2O with full recommended dose of N to irrigated gingelly raised after groundnut fertilized with 100% of recommended NPK.
  • Open furrows to a depth of 5 cm and 30 cm apart and place the fertilizer mixture along the furrows and cover to a depth of 3 cm with soil before sowing.
  • If furrow application is not done, broadcast the fertilizer mixture evenly on the beds before sowing

Application of Biofertilizer

25% of the N can be substituted by 3 packets of Azospirillum (600 g/ha) and 3 packets (600 g/ha) of Phosphobacteria or 6 packets of Azophos (1200 g/ha) by seed treatment and 10 packets of Azospirillum (2000 g/ha) and 10 packets (2000 g/ha) of Phosphobacteria or 20 packets of Azophos(4000 g/ha)as soil application.

Nutritional Disorders

Manganese deficiency: Leaves develop interveinal chlorosis, chlorotic tissue, later develop light brown or husk coloured necrotic lesions.

Zinc deficiency: Middle leaves develop chlorosis in the interveinal areas and necrosis along the apical leaf margins.
Mix 5 kg/ha of Zinc sulphate with 45 kg of soil and broadcast evenly in the beds after sowing.

Note: Do not incorporate the micronutrient in the soil.

Seed Production

Fertilizer

  • NPK @ 50:25:25 kg ha-1 as basal      
  • Apply manganese sulphate @ 5 kg ha-1 as basal

Foliar application

  • Spray 1%  DAP at the time of first flowering and again 10 days after first spray.
