Soils & Climate


  • A deep fertile, well-drained, silt loam or clay loam soil with a pH of 5.5 to 6.0 is the best for cultivation of brinjal.
  • The crop is better adapted for cultivation on heavy clay or light soils also.
  • Brinjal is rated as a moderately salt-tolerant crop and the reported salinity threshold is about 5 ds m-1.
  • In heavy clay soils and light soils, it is desirable to add well decomposed farm yard manure (FYM) @ 20-25 tonnes/ha and incorporated atleast two weeks before transplanting.
  • FYM improves proper aeration in heavy clay soils and water holding capacity in light soils which is beneficial for better growth and development of the brinjal.



  • Brinjal is a warm season crop and requires humid climate for its best growth
  • Of all the solanaceous vegetable, brinjal is the most sensitive to frost and low temperature.
  • It requires about five months of frost-free period for proper growth and development.
  • It flourishes best during warm growing season with a temperature range of 25-27oC.
  • A day temperature of below 35oC and night temperature of above 16oC considered optimum.
  • Very low temperature especially below 15oC will affect the growth of the plant as well as fruit quality.
  • Low humidity and high temperature can cause heavy flower drop and poor fruit set.
  • Brinjal also has a high-moisture requirement and responds well to irrigation during the periods of drought and high temperature.
  • It flourishes well in areas receiving a moderate rainfall ranging form 600-1000 mm.
  • It cannot withstand excessive rainfall especially during flowering and fruit set.
  • Excessive rainfall brings about defoliation, wilting and rotting of the plant.
  • Brinjal cannot tolerate water logging.
  • The crop should not to be grown after chillies, potato, tomato or tobacco because of carryover of soil-borne pathogens and nematodes.
