Step-by-step How to Grow Broccoli from seeds

How to Grow Broccoli from seeds: Broccoli (Brassica oleracea var. Italica) or green cauliflower is a new genus of vegetables. It is becoming popular day by day as it is profitable and is appreciated by everyone. Broccoli is relatively more nutritious and anti-cancer than other vegetables of the genus brassica.
Food quality per 100 grams
Protein – 3.3 grams
Starch – 3500 I.U.
Vitamin A – 200 mg
Vitamin ‘C’ is abundant and contains calcium and iron.

Broccoli originated in Italy. It is derived from the Italian word brocco. It is most popular in Italy and the United States. Broccoli has anti-cancer properties. According to Santa, a scientist at the University of California, Los Angeles, broccoli contains a special compound called isothiocyanates, which helps prevent cancer. We all know the role that broccoli plays in breast cancer prevention.

Due to the lack of vitamin A, children suffer from night blindness. Broccoli can protect children from night blindness by eliminating the deficiency of this vitamin. It also enhances immunity and eliminates the symptoms of osteoporosis. Broccoli is a very tasty and nutritious vegetable. Its anterior and orbital buds turn into green inflorescences when mature.

Inflorescence can be eaten as fry, soup, and curry. As it is lighter than cabbage, broccoli can only be boiled or eaten fresh. It is softer, more nutritious, and tastier than cauliflower. Cauliflower is to be collected only once. But broccoli is economically profitable as it can be harvested several times at intervals. Its price is also higher than the cauliflower.

Broccoli can be produced in a smaller area than cauliflower. Commercially cultivating broccoli has the potentiality to be economically very profitable. This vegetable is exportable.


Broccoli is a temperate vegetable. The temperate and humid climate is ideal for the suitable growth of broccoli. It is high temperature and drought tolerant. The average monthly temperature of 15-C to 20 C is most favorable for broccoli cultivation. The winter climate is very conducive to broccoli cultivation. Adequate sunlight is also needed.


The successful cultivation of broccoli requires an adequate amount of organic matter in the soil. It is better if the soil is fertile and the soil acidity (pH) is 6.0-7.0. Broccoli grows best in sandy loam, loam, and clay soils. However, land with irrigation and drainage facilities should be selected for broccoli cultivation.


Notable varieties are Disicco, El-Centro, Premium Crop, Green Comet, Green Duke, Crusader, Topper 43, Dundee, Italian Green, Spreading Texam 106, Walm 29.

How to Grow Broccoli from seeds

Seed sowing time

Seed should be sown before spring (1 March to 31 May). Because, broccoli is a cool-season crop, so it generally is planted in the spring or late summer for the best result.

Seed rate

150 grams of seed is required for cultivation per hectare.

Seed selection

The source and variety of seed selection should be checked for accuracy.

Seedbed preparation, seedling production

Seedling production is very important for broccoli cultivation. Open space with a drainage facility is a suitable place for making seedbed. In addition, there should be a source of water near the area to irrigate seedbed. The soil has to be deeply loosened with cultivation spade and the seedbed soil has to be made very fine. If it is clay soil, it is better to mix some sand. 3 m into 1 m seedbed need for sowing the seeds. Seeds should be sown densely in the first seedbed, then 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. 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. 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 seedbed. If the growth rate of seedlings is low, 60-100 g urea should be applied in each seedbed during the moist condition of the soil.


Seedling to seedling – 50 cm.
Row to row – 602 cm.

Land preparation

The soil of the land which gets sunlight all day long is best for broccoli cultivation. At first, land should be prepared well. It should be cultivated with 4-5 times plowing and the soil should be prepared evenly with a ladder. For planting seedlings in two rows, make a bed 15-20 cm high. A ditch 30 cm wide and 10-15 cm deep should be placed in the middle of the two sidewalks for transportation and drainage. The seedbed should be kept high. Broccoli is a cool-season crop, so it generally is planted in the spring or late summer for the best result.

Fertilizer quantity and method of application

If there is a shortage of fertilizer in the land, the growth of the plant will not be as expected and the yield will be reduced later. Therefore, the application of fertilizer in broccoli is essential. If the soil acidity (pH) is below 5.5, good results are obtained by applying 100 kg of lime per hectare. 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.


1. Light irrigation should be given one-day intervals after the first week after planting;

2. Irrigation should be done after 8-10 days;

3. After irrigating the land, then it needs to break up the soil for the normal growth of broccoli. The plants should be kept weed-free to get adequate light and air. This helps the plants to grow quickly and the yield also increases;

4. Irrigation should be done immediately after the top dressing of fertilizer to make a timely application;

5. Drains for irrigation and drainage should always be kept clean, excess irrigation water or rainwater should be removed from the land.


The best time to collect inflorescences is 60-70 days after planting broccoli. The flower buds are 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 within a month.


With proper care, the yield is 12-13 tons per hectare.
