Direct Seeding

Learning Objectives
The learner will:

  • Gain a solid understanding of direct sowing, and in doing so create the best environment for seeds to thrive

 

What Crops Should Be Direct Sown and Why?

  • Root nature of direct sown crops: often tap rooted
  • Intended density of crop: Direct-sown crops require sowing at high density and eventual thinning
  • Scale of production: Many crops are direct sown on a large scale to avoid additional production costs
  • Exceptions: Many, if not all crops, including tap-rooted crops, may be transplanted if sown and transplanted in clusters

 

Review Optimal Environmental Considerations for Seed Germination

  • Soil Moisture
  • Degree of Secondary Cultivation
  • Soil temperature

 

Preparation of Bed

  • Incorporation of green manure crop (discuss)
  • Subsoiling (discuss)
  • Forming bed, addition and incorporation of amendments - activity/demonstration. Use tractor and rototiller. Discuss that seed size dictates fineness of soil needed to direct seed. Base amendments on needs of crop

 

Seeding

  • Methods
    • Seeder - choose correct plate for seed, troubleshooting, gauging success
    • Hand - slower but more accurate, inappropriate for larger scale
  • Determining depth of seed - rule of thumb
  • Covering seed - with soil or sand - discuss pros and cons

 

Subsequent

  • Irrigation - frequent and sufficient enough to ensure good germination - critical at seedling stage in hot weather
  • Thinning - when plants reach appropriate size, thin to desired spacing - based on desired size at harvest. Demonstrate/practice thinning
