OBJECTIVE: The quality of emergence is a key point

  • The sowing depth: Between 2 and 4 cm is a key point for  a quick emergence and control the density and a better cover of soil to reduce weeds pressure
  • Insure the population, the main yield component
  • Planting date (depending on 3 main factors): Soil temperature (>= +12°C), desired flowering depends of climatic area and harvest date
  • Density of planting (depending on several factors):

o   Earliness of the planting: see table of recommendation

o   Water reserve of the soil: in dry condition, planting with a density may increase competition between plants = macrophomina and rapid exhaustion of soil’s water reserve

o   Losses during the emergence.
