Climate and soil

Climate
Brinjal is susceptible to severe frost. A long and warm growing season with temperature range of 21-270C is most favourable for its successful production. Climatic conditions especially low temperature during the cool season cause abnormal development of the ovary (Splitting) in flower buds which then differentiate and develop into deformed fruits during that season. Late cultivars, however, withstand mild frost and continue to bear some fruits. The brinjal grown in warm season shows luxurious growth and starts bearing from the initial flowers, while in cool season its growth is poor and slow and fruit size, quality and production are adversely affected.

Soil
The brinjal can be grown practically on all soils from light sandy to heavy clay loam soils are good for an early crop, while clay loam and silt loam are well suited for higher yield. Generally silt loam and clay loam soils are preferred for brinjal cultivation. The soil should be deep, fertile and well drained. The soil pH should not be more than 5.5 to 6.0 for its better growth and development.
