  • Fertilizers and manures application can be easily mechanized.
  • It is possible to develop new crop varieties due to cross pollination.

Disadvantages of using seeds as planting materials.

  • Some seeds have long dormancy and they may need special treatment in order to germinate.
  • Plants raised from seeds have variations from the mother plant due to cross pollination,
  • This may introduce undesirable characteristics.
  • Soil borne pests may damage seeds if left for sometime in the soil before rain falls.
  • Some seeds may lose viability if stored for a long time. This leads to gaps in the farm.
