Clove (Syzygium aromaticum)

Land Preparation

Selection of site
  • Select partially shaded sites having adequate protection from high winds.
  • Avoid exposed and shady locations. More than required shade delays bud formation.
  • It can be successfully grown as inter-crop in coconut and arecanut plantations.
  • In higher elevations, it can be mix-cropped with black pepper or coffee.
  • Clove prefers partial shade and comes up well at higher elevations, having well distributed rainfall.
  • Under Indian conditions, it is best suited for mixed cropping in older coconut or arecanut plantations or in coffee estates.
  • In order to give a cool humid microclimate, intercropping with banana is ideal.
  • In majority of cases, clove trees are planted in garden lands together with various other crop plants such as coconut, banana, jack, mango and others.

Propagation

Seeds and sowing
  • Clove is propagated through seeds obtained from fully developed fruits known as mother of clove.
  • Collect fully developed fruits from high yielding mother trees.
  • Dehusk the fruits immediately after collection by soaking in water and peeling.
  • Prepare raised nursery beds with fertile soil rich in humus under the shade of trees.
  • Sow the seeds flat at a depth 2-5 cm and a spacing of 12-15 cm.
  • Water the beds regularly.
  • Seedlings can either be retained in the nursery till they attain a height of 25-30 cm when they are ready for transplanting or potted when they are six months old and transplanted after another 12-18 months.

Planting

  • Select 18 months old seedlings for planting.
  • Prepare pits of size 60 cm x 60 cm x 60 cm at a spacing of 6 m x 6 m about a month in advance of planting.
  • Allow to weather.
  • Fill up the pits with mixture of burnt earth, compost and topsoil.
  • Plant the seedlings during the rainy season, May-June or August-September.
  • Provide shade and irrigation during breaks in the monsoon and summer.
  • Banana or glyricidia may be planted to provide shade.
  • Clove is generally grown as a mixed crop with coffee, coconut, arecanut etc.
