Description of Cauliflower – Growth Guide

Growing Cauliflower outdoors, if done in a rational, scaleable basis – could be a great way to earn money. In short, the majority of cauliflower farming start with planting from the seeds (hybrids) within an enclosed environment that is protected. While they wait for the young seedlings to mature and be ready for transplantation (usually around 30 to 60 days) then they begin to make the fields. They till the field and remove any previous cultivation residues, weeds, and incorporate in the soil the base fertilization along with the well-digested manure. Then, they design and construct the drip irrigation systems.

Cauliflower farming involves various steps, once the farmers are prepared for transplanting, they make tiny hole in their soil where they place seeds. Fertilization, Drip Irrigation as well as Weed Management are used in the majority of instances. The majority of commercial varieties of cauliflower can be harvested within 60 to 150 days following transplantation. The time from planting to harvesting is dependent depending on variety, the climate along with the age and condition of seeds planted. Harvesting is done with hand-chopping or cutting tools and is usually done in several sessions. This is due to the fact that farmers frequently plant continuously in order to meet the continuous demand.

After harvesting, the cauliflower farmers chop and then destroy the remnants in the field. They rotate the cauliflower (with other plants that don’t belong to the Brassicaceae genus) to combat the spread of diseases and stop soil being depleted.

The most limiting factor in cauliflower farming is the weather. The plant needs moderate temperatures to flourish and develop flower-heads which is our primary objective. They are susceptible to frost once it becomes a problem with low temperatures. In addition, high temperatures can create problems, particularly for the heads, which start to change colour or (even more threatening) bloom. For optimal temperatures are those that fall between 14 to 20degC (57-68) but some varieties are able to tolerate temperatures as high as thirty degrees (86 degrees Fahrenheit) for a brief period.

It is essential to choose the method of growing and also the cauliflower varieties that are thriving in your region. There are two ways to cultivate cauliflower: planting directly in the field, or planting in a nursery, before transplanting.

How to grow Cauliflower from Seeds – How to grow cauliflower seedlings

In general professionals do not prefer sowing cauliflower seeds directly in the field due to a variety of reasons. First, the cauliflower seeds are small, and so sown outdoors can result in uneven sowing. In addition, when tiny cauliflower plants are seen out of the earth, they will become typically a food source for snails as well as other pests of the soil. If you are insisting on growing your cauliflower seeds outside, the best time to plant them is most likely to be during the sprigtime or in the fall. If you start in the spring, your cauliflowers are ready to harvest during the summer. If you begin in the fall and fall, they’ll be harvested by the winter. The only thing you need to do, once you have prepared the field is to make rows of 70-80cm (27.5-31.5inches) in distance from one each other, and make holes that are between 20-40cm (7.9-15.7 inches) within the row. After that, you can plant 3-4 seeds per hole of 0.5-1.5 cm (0.2-0.6 inches) depth, and then lightly cover the soil. You can water them immediately following sowing.

Cauliflower germinates best at 26 degC (80 degF) temperature on average. The seed must have optimal levels of moisture in order to germinate. The over-watering can cause harm. Some farmers water on a regular basis day during this time. When conditions are optimal the seeds of cauliflower germinate in 8-10 days. Following germination, you’ll likely need to reduce the size of your plants. If there is more than one plant that sprouted then you must take out the least healthy one from each sowing spot. In the average, you’ll require 1.25kg (2.2pounds) of seedlings per hectare. Be aware that each grammar (0.034 oz.) of cauliflower seeds has approximately 270 to 320 cauliflower seeds.

The majority of cultivators of cauliflower start their crops from the seeds (hybrids) inside a environment that is protected. The growers plant plants of cauliflower in seedbeds that are kept at a control of temperature between 20 and 30 degrees Celsius (68-86degF) and after that, they transplant them into their final places. They plant 3-4 seeds per container at 1cm (0.4inch) in depth. They lightly cover them with soil. The majority of them employ turf as a substrate for optimal air circulation. It is vital to keep the soil moist, but not so wet that the seed begins to sprout. Seeds should germinate between 8-10 days. The seedlings are ready to be transplanted after 30 days (3-5 months). At that point, they’ll be able to develop 3-5 real leaves. They will be taller than the average of 12cm (4.7 inches).

Cauliflower’s Climate and Soil Requirements – Where can you grow cauliflower

Cauliflower is a vegetable that is cool-seasonal. It is able to endure temperatures as low as 4degC (39degF) without any issues. For ideal temperatures for cultivation of cauliflower are those that fall between 14 to 20 degC (57-28degF). If the plant of cauliflower experiences higher temperatures in its first growth stage the plant will begin to undergo an intense growth of the stem and hinder the development of flower heads. If temperatures are higher than 20 degrees Celsius (68degF) the plant begins to produce curds that are leafy. This is something that we must to stay clear of. Temperatures above 26 degrees Celsius (78.8degF) are likely to alter the head’s colour and bloom, which will reduce the quality of their product and its value to consumers. But, today we have hybrid varieties of cauliflower which are genetically programmed to withstand temperatures of up to 37 degrees Celsius (99degF).

Cauliflower is able to grow in a myriad of soil types. It is most productive in slightly acidic soils (pH approximately 6.5). The plant has a middle tolerance to high soil and salinity levels. While cauliflower plants are fond of the sun, know that the majority of people prefer white heads over mildly yellow ones. This is why farmers often tie some of the outside leaves to the curds to keep the curds from turning yellow.

The Soil Preparation

The soil preparation process begins about two weeks prior to transplanting the seedlings of cauliflower. Farmers are able to plow the soil well at this time. Plowing helps improve soil aeration and drainage. In addition plowing eliminates stones and other unwanted material out of the soil.

A week prior to planting farmers often apply a fertilizer for pre-planting, like well-rotted manure or synthetic slow-release fertilizer. Always following a consultation with a licensed local Agronomist. A lot of farmers incorporate manure with tractor. The following day is the ideal time to put in drip irrigation. After installation, farmers could apply soil-cleaning substances. They inject them into the irrigation system in the event that soil analysis has found soil infections (ask an agronomist who is licensed in your region).

Cauliflower Flowering as well as Plant Spacing Cauliflower Plants for a hectare

When it comes to the planting of seeds of cauliflower in the field, there are two primary times to pick from. The first begins by planting in the spring to ensure that the cauliflowers are in good shape for harvesting by the end of the summer. The second time frame includes the planting of autumn, and harvesting in winter.

In many instances the most appropriate time to plant your cauliflower outside is in the fall. However, bear in mind that during this time the cauliflower plants need be able to undergo vernalization before they will develop the heads. Farmers typically prefer plants that have been in cultivation between 3 and five weeks. At this stage, they have grown 3-5 leaves and an average height of 12cm (4.7 inches).

After completing all the preparatory steps (plowing and fertilization of the basal layer Tillage, installing the irrigation systems) it is now time to begin transplanting. Growers mark the precise locations on which they will plant the seeds. They then dig holes , and plant seeds. It is vital to plant seeds at the same level as they were at the nursery. Many growers prefer planting the cauliflower every two weeks. They do this to be capable of harvesting cauliflowers regularly.

They plant their cauliflowers in twin rows or single rows. Single rows maintain between 20-40cm (7.9-15.7 inches) distance between the plants in the row, and the 40 to 90cm (15.7-35.4 inches) distance between rows. In two rows, you maintain the 1m (39 inches) distance between a couple of rows and 30cm (11.8 inches) between people in the same plant. Plants are again placed at intervals of 20-40cm (7.8-15.7 inches) between rows.

In most cases, farmers plant 25000-45000 plants per hectare. (1 hectare = 2,47 acres = 10.000 square meters). There are instances where the number of cauliflowers within a hectare may range from 20.000 as well as 50.000 (overcrowded). The distances and numbers of plants are based on varieties of cauliflower and the conditions in which they grow.

Cauliflower Water requirements along with Irrigation Systems

Cauliflower farming does not typically endure drought, and the cauliflower’s quality can decrease significantly under water-stressed conditions. This is why most farmers water their plants frequently, even during winter. However excessive water can cause root rot that can cause the entire plant to collapse and huge loss of yield. Cauliflower is susceptible to collapse within a couple of days when it is soaked with water.

The most important times in the irrigation of cauliflower is during the initial stage, until seeds start sprouting and the second time when the head is flowering. The majority of producers water their plants by providing regular amounts of water on a daily basis. They supply little amounts of water during the initial stages and gradually increase the amount as the plant develops. In the summer, watering sessions might need to be increased to a daily one.

Naturally, the requirements for water will differ based on soil and weather conditions. For instance, clay-rich soils typically require less irrigation as compared to sandy soil. Different varieties of cauliflower may require different amounts of water.

The most widely employed irrigation method for cultivation of cauliflower is drip irrigation.

Cauliflower Fertilization Requirements

The first step is to consider the condition of your soil field by conducting the semiannual or annually conducted soil test prior to applying any fertilization technique. Every field is not identical. Therefore, nobody can provide advice on fertilization methods. It is important to consider your soil’s test results as well as the analysis of tissue and the history of your crop. But, we will provide the most commonly used fertilization methods that are used by a lot of farmers.

Cauliflower plant needs a high amount of fertilizer for growth and to form a healthy head. This is why it is regarded as an incredibly hungry crop.

For producing 20 tonnes per hectare, certain farmers could require 120kg of nitrogen 50kg 5P2.O5, as well as 200kg of K2O.

In many instances, producers begin with a basic fertilization. They add to the soil one-third of total Nitrogen as well as the complete quantity of P and K. They can also apply between 25 and 40 tons of manure that is well-digested per hectare. After that, they continue adding the remaining Nitrogen in two separate applications. The first is within a week of transplanting, while the second one is 1 month following the first.

Certain experienced farmers recommend a balanced slow release fertilizer comprised of essential nutrients, like Nitrogen(N), Phosphorus(P), and Potassium(K) (e.g. 20-20-20) which are in form of Granules. It is possible to add the fertilizers granular directly on the soil’s surface, and then water. Granules shouldn’t be directly in contact with the plants as there is danger of burning.

But, the majority of farmers prefer the method of the process of fertigation (injection into the soil of fertilizers that are water-soluble within drip irrigation systems). In this scenario they can use different levels of fertilizers per day. The growth of cauliflower is divided into three phases. The first begins from the day of transplanting (day 1) up to day 45. In this time they apply an average of 1kg of N, one kg 2O 5 and 1 kg of 2.O5, and 1kg of potassium2.O per hectare every day. The second phase begins from day 46 and runs until day 70. The second period is when they increase their rates and apply on average 3 kg of N, 1 kilograms of P2O5 and 3kg of K2O per hectare each day. The third phase begins from day 71 until the harvest. In this time the farmers apply on average 0,75kg of nitrogen and 1kg in K2,2O per hectare each day.

But, these are general patterns that should not be followed without conducting your own investigation. Each area is unique and requires different requirements. Examining the soil’s conditions and pH is essential prior to applying any fertilization technique. It is recommended to consult with your local certified agriculturalist.

Cauliflower Oured Management

A key aspect of the cultivation of cauliflower is controlling weeds. Cauliflower is often a victim of growing weeds in the beginning of growth. The weeds are a threat to young plants for availability of space, access to sunlight and water, as well as nutrients. All growers of cauliflower must employ an effective weed control plan. This can vary significantly in different countries, the laws, methods of production, and also the sector that the product is marketed. A weekly manual weed control is often required in certain situations (organic manufacturing). If the cauliflower has grown enough, weeds shouldn’t be an issue.

Cauliflower Harvesting What is the best time and method to collect Cauliflowers

Most cauliflowers are ready to be harvested 60 to 150 days following transplantation. But, the time to harvest is contingent on the variety and also on the environmental conditions. The cauliflowers can be harvested by the time that the heads have reached the ideal size for their species. The heads must be small and uniform in hue.

Harvesting is performed manually using cutting tools or scissors in the evening. In other circumstances, the sun’s rays could cause sunburns to the curds as well as foliage becoming wilted. Producers slice the curds with 3-4 leaves in the middle surrounding them. The delay in harvesting can drastically reduce the quality of the product, since there is a possibility for the heads becoming loose and become yellow.

Cauliflower produces per hectares and acres.

A good yield is between 20-40 tonnes per one hectare (17.851,2and 35.702,3 pounds per acres) which is 25.000 curds. Remember that a hectare is 2,47 acres, which is 10.000 acres. The weight of each head is contingent on the variety and the growing conditions. This can be accomplished through experienced farmers of cauliflower who have many years of expertise. The cultivation of cauliflower can yield substantial profits. Recent years have seen is a growing need for the cultivation of cauliflower within regions that are located in Southern Europe and the Mediterranean region.

Cauliflower Anomalies – Common cauliflower ailments

Sunburn

Cauliflower heads are susceptible to sunburns. The plant defends itself with a protective covering of the curds with foliage. Certain varieties, however, lack this protective foliage inside, and the producers respond by covering their heads with leaves from their outer leaves.

Cauliflower Pests and Diseases

Pests

Pieris brassicae

Pieris is the most deadly cauliflower enemy, it’s a caterpillar with white color which attacks cruciferous plants. The parasite’s larvae feed on the foliage and cause significant quality decline and significant yield loss. After the plant is attacked, managing becomes more difficult. Since pests acquire immunity to pesticides very easily, the best way to manage them is to use biological control. Pheromone traps are the most commonly employed technique. They draw male insects away, thereby and keep them away from females with fertile eggs. Therefore, traps decrease their number.

Beet armyworm

Spodoptera exiqua is among the most dangerous cauliflower pests. Larvae of this pest form holes in the foliage for feeding, causing leaves to die and wilt. After the crop is attacked, managing is more complex. Since pests acquire immunity to pesticides quickly, the most effective method of controlling their spread is to use biological control.

Diseases

Downy Mildew

Downy mildew is an illness which is brought on through an organism known as Hyaloperonospora parasitica. The pathogen is attracted by humid conditions that cause distinctive spot of chlorosis on the upper leaf surface, and an edgy, downy-looking mold on the lower side. Heads also suffer from the disease because they develop necrotic brown spots on the surface. The disease can be dangerous since it can cause substantial losses in yield. Controlling the disease begins with precautions. These include controlling weeds and the proper spacing between plants, proper drainage, and the avoidance of watering the foliage. The general health of the vegetation (nutrients and water levels as well as exposure to sunlight) can boost their resistance. Chemical treatment is only recommended in cases of severe disease and under the supervision of an accredited local agronomist. It is also essential to ensure the right sanitation practices, like instruments disinfection each time we work with plants.

Powdery Mildew

Powdery mildew is a fungus that is caused by the fungus Erysiphe cruciferarum and can turn dangerous, leading to loss of production. Its symptoms include spots of chlorotic. When the temperature is at its highest and the moisture is at its lowest conditions, a layer of powder similar to flour is formed on the top of the leaves. Management involves the same strategies employed for controlling downy mildew.

Alternaria

Alternaria is a very serious illness that is triggered by the increase in soil moisture. It is caused by the fungus Alternaria brassicae that is the cause of the illness. The pathogen is found in all parts of the plant, including the soil. The most prominent symptom of the disease are brown necrotic spots that appear on the top on the flowers’ heads. Insufficient irrigation can accelerate the progression of the disease.
