About Brinjal: Brinjal is a resilient crop that may be grown on a variety of soils. The crop prefers a well-drained and healthy soil because it is a long-term crop with a large yield. Crops cultivated in sandy soils mature sooner, while those planted in clayey soils mature later. The ideal pH for crop cultivation is 5.5-6.6.
It thrives best in temperatures ranging from 13 to 21 degrees Celsius on a regular basis. When the temperature drops below 17 degrees Celsius, the crop’s growth is greatly hampered. It can be grown all year on the plains, but the rabi season (October-November) is the finest. The crop prefers soil that is well-drained and fertile.
Varieties: Varieties are Pusa Shymala, Pusa Purple Long, Pusa Purple Cluster, Pusa Kranti, Pusa Bhairav, Pusa Anmol (H), Pusa Hybrid 5 (long), Pusa Hybrid 6 & 9 (round), Arka Sheel, Arka Shirish, Arka Kusumkar, Arka Navneet (Hybrid), Arka Nidhi, Arka Keshav and Arka Neelkanth.
Procedure and chemicals required: Seed treatment with Trichoderma viridae/T. harzianum @ 2g/100 g of seeds or Carboxyn 37.5 percent + Thiram 37.5 percent is necessary for one hectare. Raised beds with a size of 7.2 x 1.2 m and a height of 10- 15 cm have been prepared. As a result, ten beds are required for a one-hectare space. Drenching the beds with Bavistin (15-20 g/10 litres of water) to prevent seedling mortality due to damping off.
Seeds are planted at a depth of two to three centimetres, covered with a fine layer of soil, and lightly watered with a water can. When the seedlings reach a height of 15 cm and have 2-3 true leaves, they are ready to transplant within 4-6 weeks of planting.
Long-fruited kinds are planted 60 x 45 cm apart, round variants 75 x 60 cm apart, and high-yielding varieties 90 x 90 cm apart. 15-20 tonnes of FYM are added to the soil. For maximum yield, 150 kg N, 100 kg P2O5, and 50 kg K2O are advised. On the first and third days after transplanting, a modest irrigation is applied. After then, irrigation is delivered every 8-10 days in the winter and every 5-6 days in the summer.
Pest control: Weed control is effective with a pre-emergence spray of Fluchloralin (1.5 kg a.i./ha) along with one hand weeding 30 days after transplanting.
For hoppers, aphids, white flies, and other pests, delta and yellow sticky traps should be put at a rate of 2-3 per acre. Against sucking pests, spray 2 to 3 times with a 5 percent NSKE solution. After that, use imidacloprid 17.8 SL @ 150 ml/ha and apply neem oil (2%) to help reduce borer infestation, though only significantly. For monitoring and mass capturing of the shoot and fruit borer Leucinodes orbonalis, pheromone traps at a rate of 5 per acre should be set. After every 15-20 days, replace the lures with new lures. Crop rotation should be used with non-solanaceous crops. The use of green manure, polythene mulching, and soil application of bleaching powder will help to reduce bacterial wilt disease infection.
Productivity: After 120-130 days of seed sowing, the fruits are ready to pick for the first time. Fruits are collected every 8-10 days on average. Brinjal yields range from 20 to 30 tonnes per hectare.
