Nutrition Facts, Health Benefits and Production Technology of Broccoli.
Broccoli (Brassica oleracea var. Italica) or green cauliflower is a new genus of vegetables for Bangladesh. Even a few days ago, broccoli was an unfamiliar and uncommon vegetable among the people of Bangladesh. But now it is becoming popular day by day as profitable and is appreciated by everyone in our country. Broccoli originated in Italy. Broccoli is called Italian Bokli. It is derived from the Italian word brocco. It is most popular in Italy and the United States.
Nutrition Facts of Broccoli :
Broccoli is relatively more nutritious and anti-cancer than other vegetables.

Health benefits of Broccoli :
- Santa Barbara, a scientist at the University of California in the United States says, Broccoli contains a special type of compound called isothiocyanates which plays a role in preventing cancer. We all know the role that broccoli plays in breast cancer prevention.
- Due to lack of vitamin A, children in our country suffer from night blindness and blindness. Broccoli can protect children from night blindness and blindness by eliminating the deficiency of this vitamin.
- Increases immunity and eliminates the symptoms of bone deformities.
Production technology of Broccoli :
A cauliflower is to be collected only once. But broccoli is economically profitable as it can be collected several times in a row. Its price is also higher than cauliflower. Broccoli can also be produced at home in proportion to cauliflower. Commercially grown broccoli has the potential to be economically viable. These vegetables are exportable.
Broccoli is a temperate vegetable. Temperate and humid climate is ideal for the growth of broccoli. It is high temperature and drought tolerant. The average monthly temperature of 150 C to 200 C is most favorable for broccoli cultivation. The winter climate of Bangladesh is very conducive for broccoli cultivation. Adequate sunlight is also needed.
Successful cultivation of broccoli requires an adequate amount of organic manure in the soil. It is better if the soil is fertile and soil acidity (pH) is 6.0-6.0. Broccoli is best grown in sandy loam, loam and clay soils. However, land with irrigation and drainage facilities should be selected for broccoli cultivation.
Seed sowing time:
Up to Bhadra-Ashwin (mid-August-mid-October) months. Seeds can be sown in the seedbed till the month of Kartik (mid-November). However, the last week of September is the best time to sow seeds.
Seed rate for Broccoli:
150 grams of seed is required for cultivation per hectare.
The source and variety of seed selection should be checked for accuracy.
Varieties of Broccoli:
Broccoli is a cold weather crop and is cultivated only in Bangladesh during Rabi season. Scientists at Raikhali Agricultural Research Center in Bangladesh released 1 variety of Bari Broccoli with relentless efforts. Notable foreign varieties are Disicco, El-Centro, Premium Crop, Green Comet, Green Duke, Crusader, Topper 43, Dundee, Italian Green, Spreading Texam 106, Walm 29.
Seedbed preparation, seedling seedling production:
Seedling production is very important for broccoli cultivation. Open space with a drainage facility is a suitable place for making seedbeds. Moreover, there should be a source of water near the edge to irrigate the seedbed. The soil has to be deeply loosened with cultivation or spade and the seedbed soil has to be made very fine. If it is clay soil, it needs to mix some sand. For sowing the seeds need to be 3 m 1 m seedbed. Seeds should be sown densely in the first seedbed, seedlings should be transferred to the second seedbed 10-12 days after seed germination. Seedlings should be planted 2.5 cm apart in rows at a distance of 5-0 cm in the second seedbed. Irrigation and shade should be given immediately after planting. It will take 5-6 days for the seedlings to be established.
Seedling to seedling – 50 cm.
Row to row – 602 cm
At this time one day after another irrigation should be given. Irrigation needs to be done for 5-6 consecutive days. This strengthens the seedlings. With extra irrigation, the seedlings become leaky, tall and weak and the yield from the next plant is not as expected.
Land preparation of Broccoli:
Soil that receives sunlight throughout the day should first be well prepared by tillage. The land should be tilled and leveled with 4-5 landscaping and ladders. To plant the seedlings in two rows, make a bed wide and 15-20 cm high. There should be a 30 cm wide and 10-15 cm deep ditch in the middle of the two sidewalks for transportation and drainage.
Fertilizer quantity and method of Fertilizer application:
If there is a shortage of organic fertilizer in the land, the growth of the plant will not be as expected and the yield will be reduced later. Therefore, application of organic fertilizer in broccoli is essential.
If the soil acidity (pH) is below 5.5, good results can be obtained by applying 100 kg of lime per hectare. 7-8 days before transplanting seedlings in the second seedbed, 150 g TSP, 100 g urea and 100 g MOP should be applied in each seed bed. If the seedling growth rate is low, 60-100 g of urea should be applied in each seedbed in moist soil.
Filling the gaps:
Some more seeds should be sown while sowing in the seedbed. Some seedlings may die after planting in the main field or land. When the seedlings of the main field die, the gaps can be filled with these seedlings of the same age.
After care :
- Light irrigation should be given one day after the first week after planting;
- Irrigation should be given after 8-10 days;
- After irrigating the land, ‘Joe’ actually needs to break the soil for normal growth of broccoli. The trees will be weed free as well as get adequate light and air. Trees will grow faster and yields will also increase;
- Irrigation should be done immediately after application of fertilizer to make timely application of fertilizer;
- Drains for irrigation and drainage should always be kept clean, excess irrigation or rain water should be removed from the land.
70-80 days after planting of broccoli is the best time to collect inflorescences. The flower buds need to be cut and collected with a sharp knife or blade with a three inch cut. In this way broccoli can be collected from the same land several times in a month. Flower buds should be collected in a fairly compacted state.
With proper care, yield is 12-13 tons per hectare.
