Nutrition Facts, Health Benefits and Production Technology of Brinjal

Vegetables are very important in our daily diet, no matter what kind of food we eat, expensive or cheap. Every day we eat different types of vegetables in one way or another. Because vegetables contain all kinds of food ingredients. Among them are vitamins and minerals which are very important for our body.

Almost all of our body’s need for vitamins and minerals is met by vegetables.Nowadays, doctors are advising patients to eat more vegetables as a diet instead of medicine, such as heart disease, skin disease and diabetes. Again green or colored vegetables are extremely beneficial for eye problems. So not only as food, but also for medicine, diet, nutrition and a balanced diet, if we want to eat a variety of vegetables every day, it is necessary to produce vegetables. 

So if we can produce as many different kinds of vegetables as we can, we will be able to meet the needs of our family as well as earn some money. 

Nutrition of Brinjal and Its Health Benefits and Production Technology

Brinjal belongs to the Solanaceae family. It is scientifically known as Solanum melongena.

  • Brinjal helps control our blood sugar levels.
  • Manganese is found in brinjal. Various studies have shown that manganese helps strengthen bone structure by building bonds with calcium and vitamin D.

Cultivation technology of brinjal : 

Suitable land and soil:

Who can cultivate brinjal in all types of soils and in all areas of Bangladesh. However, in the rainy season, such high lands have to be selected as the water does not accumulate. Moreover, eggplant is cultivated in light sand to heavy metal soils i.e. almost all types of soils. Light sandy soil is suitable for early variety eggplant cultivation.

To cultivate eggplant in this type of soil, it is important to apply a lot of organic manure and other fertilizers frequently. Ethanol loam and poly loam soils are suitable for eggplant cultivation and eggplant yield is higher in these soils.

Seed:

Proper Seed Selection: The characteristics of good seeds are as follows-

Must be disease free, clean, nutritious and chit-free.

The size and shape of all the seeds will be the same.

Seed rate:

Generally 110-115 gm seedlings are required per acre. In case of high yielding varieties, the instructions which are written on the seed packet should be followed.

Seed treatment:

For every kg of seed, 2.5 gm of Vitavax-200 fungicide and seed should be poured in the container and shaken in such a way that the fungicide sticks well on the seed. Purified seeds should be taken out of the pot and dried in the shade. It is better to purify the seeds six hours before sowing.

Land preparation:

Land Cultivation:

Generally, to make field land, the soil has to be plowed 4-5 times with a ladder.

Seedbed preparation :

The soil in the seedbed should be fertile. Organic fertilizers and small amounts of phosphate fertilizers can be used if fertility is low. For every square meter of seedbed, 1-2 bags of rotten dung manure and 30 gms of TSP manure can be used. After cultivation, the entire land should be divided into a few small seedbeds. Each seedbed should be 3-5 m in length, 1 m in width and 6-7 inches from the side. Besides, 1-1.5 hand space should be kept between the two seedbeds. The seedbed should be raised with soil from this empty space.

Seedbed care:

Light irrigation should be given at 2-3 days interval after seedling emergence.

Method of sowing and planting:

Time of sowing and planting: Asardha-agrahayan, but in case of high yielding varieties, sowing and planting should be done as directed on the packet.

Spraying or line sowing:

Seedling distance depends on variety, soil fertility and production season. Generally, in case of large size eggplants, seedlings can be planted in rows at a distance of 2-2.5 feet in rows and in case of small varieties, seedlings can be planted in rows at a distance of 1.5-1.75 feet in rows of 2 feet. The seedlings should be planted in the afternoon if possible so that the seedlings do not dry out immediately after planting.

Planting:

35-45 days old seedlings are suitable for planting. At this time the seedlings grow 5-6 leaves and the seedlings are about 6 inches long. Brinjal seedlings can be planted even if they are a little older. The soil should be moistened with water in the seedbed 1-2 hours before transplanting so that the roots are not damaged during transplanting.

Fertilizer management :

For 1 acre of land,  fertilizer dose should be as followed : 

Compost :  4-6 tons ; 

Urea :       180 Kg urea should be applied equally in three installments.

TSP :        120 Kg TSP should be applied in the first installment and 60 kg in the second installment. 

MOP :      120 kg MOP should be applied in 2 installments. 

Gypsum :   60 kg Gypsum can be applied. 

Weed control

Time:

If weeds appear in the land, the soil should be cleaned and loosened. Lightly loosen the soil and weeding can be done after certain days to improve the roots of the tree.

Methods of control:

Weeds can be controlled with the help of hoe / spade

Irrigation system:
Irrigation time:

Irrigation is essential for brinjal cultivation. Brinjal roots do not go very deep in the soil so frequent irrigation is required to get good yield.

Irrigation amount:

Frequent moderate dose.

Drainage:

Brinjal cannot tolerate standing water, so drainage should be facilitated.

Disease and insect control : 

Wilting :

1. As soon as you see the fallen seedlings, you have to pick them up and destroy them.

2. Don’t keep the land moist or wet at all times and keep the drainage system. Ridomil Gold 6 WG – Mix Ridomil Gold at the rate of 5 gm per liter of water and spray well on 5% of the land.

Downy mildew :

Thiovit 60 WG – Mix 50 g of thiovit per 10 liters of water and spray on 5% of the land after 15 days.

Leaf blight :

Sow refined seeds and soil of seedbed can be treated using Ridomil Gold 6WG (5 g per liter of water for 5% of the land). 2. Infected trees should be uprooted and destroyed

Leaf Mosaic :

Infected plants should be removed and destroyed.2. The field should be kept free from weeds. It is needed to control white flies (Ektara 25 WG-2.5 g Ektara should be mixed in 10 liters of water and sprayed well).

Insects : 

Shoot and fruit borer :

Nimbecidine should be applied in 60 ml / acre of land.

Nimbicidi

Fighter 2.5 EC-410 ml / l. Water

Fighter 2.5 EC

Ripcort 10 EC should be applied in 200 ml / acre of land (1 ml / l water) Ripcort 10 EC

Sabikran 425 EC, 400 ml / acre should be applied to the land.

Cutworm :

After planting 2.5 EC- brinjal seedlings per carat, mix 3 ml carat per acre with required water and spray by soaking rows.

Gola 48 EC – 1.40 l / acre (69 ml / 10 l – 5 per cent land)

Mili bug :

Tear off the affected leaves and tips at the initial stage.2. If possible, destroy the pile of eggs or insects by hand. Nimbicidin should be applied in 60 ml / acre of land.

Harvesting

Time:

Fruits should be collected before they are fully ripe. It is suitable for fruit collection when the fruit is full size but the seeds are not hard. Fruit Skin will be bright and shiny during collection.

Method:

Harvesting is done by hand / sharp bamboo twigs
