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 as optimum better growth and development.
Brinjal is a warm season crop and requires a long warm growing season. it is very susceptible to O frost. A daily mean temperature of 13-21 C is most favourable for its successful production. Brinjal is highly susceptible to frost injury. The growth of the crop is severely affected when temperature O falls below 17 C. It can be successfully grown as a rainy season and summer season crop and can be grown at an elevation of 1200m above the sea level.
Nursery Bed Preparation :
Brinjal seeds are sown on nursery beds to raise seedlings for transplanting in the field. Raised beds are necessary to avoid problem of water logging in heavy soils. In sandy soils, however, sowing can be taken up in flat beds. Raised beds of size 7.2 x 1.2 m and 10-15 cm in height are prepared. Thus, ten such beds are sufficient to raise seedlings for planting one hectare area. About 70cm distance is kept between two beds to carry out operations of watering, weeding, etc. The surface of beds should be smooth and well levelled. Well-decomposed FYM or leaf mould may be mixed with the soil at the time of bed preparation. To avoid mortality of seedlings due to damping off, drenching of the beds with Bavistin (15-20 g/10 litres of water) is effective.
Raising of Seedlings :
About 250-300 g of seed are sufficient for raising seedlings for one hectare of land. Prior to sowing seeds are treated with fungal culture of Trichoderma viride (4 g/ kg of seed) or Thiram (2g/ kg of seed) to avoid damage from damping-off disease. Sowing should be done thinly in lines spaced at 5-7 cm distance. Seeds are sown at a depth of 2-3 cm and covered with a fine layer of soil followed by light watering by water can. The beds should then be covered with dry straw or grass or sugarcane leaves to maintain required temperature and moisture. The watering should be done by water can as per the need till germination is completed. The cover of dry straw or grass is removed immediately after germination is complete. During the last week in nursery, the seedlings may be hardened by slightly withholding water.
The seedlings are ready for transplanting within 4-6 weeks of planting when they attain a height of 15 cm with 2-3 true leaves. The sowing and transplanting time in different seasons are as follows
