Brinjal is a warm season crop and requires a long warm growing season. But, it can be successfully grown as a rainy season and summer season crop and can be cultivated even at an elevation of 1200 m above MSL. However, the crop is very susceptible to frost and crop growth is severely affected when temperature falls below 17°C. Brinjal can be grown on all types of soils. However, it grows best in loose, friable, well-drained silt loam or clay loam soils rich in organic matter. An early crop gives good yield in light soils. The crop is moderately tolerant to acidic soils and a pH range of 6.0-6.8 is considered optimum for its growth and development.
