Castor

Land Preparation

  • For good growth, castor requires a well pulverised seed bed with loose subsoil upto 45 cm depth.
  • However, it does not require fine tilth, but for even germination it requires adequate moisture for longer period in seed bed, preferably to a depth of 15-20cm.
  • Deep ploughing is advantageous in many regions of India, especially for rainfed castor as this practice will help in absorption and conservation of more rain water.

  • It is also a common practice on light soil areas to plough the land once in summer months, followed by harrowing once or twice with the receipt of pre-monsoon rains.
  • Chalka soils which are 6-12 inches deep, a good ploughing to a depth of 12 inches gives a good growth of crop.
  • In clay loams only harrowing is done by blade harrows two to three times to bring the soil to proper tilth.
  • In laterite soils, deep ploughing is specially advantageous to break the compact layers in sub soil.
  • For irrigated castor in rabi and summer, the field is laid into ridges and furrows with desirable distance between the ridges.
