Sowing in Sweet Sorghum
- Deep black soil (Vertisol) or deep red loamy soil ( Alfisol ) with a soil depth of ³ 1.0m is preferred.
- Seed rate 8-10 kg ha-1.
- Treat the seed with Carbendazim or Thiram @ 2g per kg of seeds and with Azospirillum @ 600 g per 10 kg of seeds
- Spacing: 45-60 cm ×12-15 cm; (Row to row distance: 45-60 cm; & plant to plant distance: 12-15 cm)
- Two to three seeds are dibbled in each hill/planting hole and the seedlings are to be eventually thinned to one per hill.
- If a planter is used, then the existing seed rate will be reduced to 8 kg
- Pre monsoon sowing or dry sowing of sweet sorghum is effective for improving rainfall use efficiency as the crop takes advantage of early monsoon without considerable effect on germination
- Sowing in June for rainy season; sowing starts in October for postrainy season. However, sowing should be avoided during cold months, under summer irrigated, sowing during February is feasible
- Delayed sowing of sweet sorghum beyond 5th July, attracts shoot fly
- Crop rotation with legumes is necessary for sustainability of yields on long term basis.
- Sweet sorghum/pigeon pea (2:1) intercropping is also viable in vertisol.
- Dry sowing cum fertilizer application with tropicultor.
- Planting on light shallow soils should be avoided.
- The ideal pH range is 5.0-8.5
