Vegetable Brassicas

Elaborated by our specialists, Yara's fertilizer program for vegetable brassica can help you to achieve excellent crop performance.

Agronomically, the key to top performing crops is balanced plant nutrition. High brassica yields are obtained on fertile soils where water is not limiting. Good soil structure is essential for strong root development.

It is important to produce a complete crop canopy as soon as possible after planting and then to maintain productive leaf areas for a long period, in order to maximize growth.

Good nutrition is an essential pre-requisite for a high quality brassica crop.

Brassica compactness, size, weight and color vary depending on the market needs and also on the different brassica types.

Controlled atmosphere storage is increasingly practiced to maintain quality in store over longer periods and extend the marketing period.

Good nutrition is an essential pre-requisite for improved brassica sugar content, resulting in sweeter and tastier crops.

Vitamin C, calcium and glucosinolates in brassica vegetables are significant health promoting compounds.

Tipburn is a major concern in head forming brassicas, because it develops approaching maturity, or during storage, after the majority of investment has been made in the crop.

Hollow stem is a physiological disorder in cabbage, cauliflower and broccoli - frequently linked to calcium and boron deficiency or over-supply of nitrogen.

Black petiole or black midrib is an internal disorder of cabbage, which occurs as the head approaches maturity.

Clubroot is caused by a soil-borne fungus and affects all brassica species.

Deficiencies should always be checked by using leaf tissue analyses, as many of the symptoms resemble each other.

Black speck (also called pepper spot, spot necrosis, petiole spot, and gomasho) is a disorder that consists of very small to moderate size discolored lesions on the midrib and veins of the leaves.

Cabbages are cool season crops that best suit a maritime climate with mild temperatures.

There is a range of quality standards for cabbages.

Soil and leaf tissue analyses should be used to assess nutrient imbalances.

Vegetable brassicas have many and varied growth habits.

Soils need to be well structured and fertile to maximize growth and produce high yields.

Head forming cabbages, brussel sprouts, cauliflower, broccoli, kale and kohlrabi.

Around 70 million tonnes of cabbages are produced annually, with the crop being grown across 3.8 million hectares in nearly 150 different countries.

Crop rotation is important to avoid soilborn diseases such as clubroot, xanthomonas, and verticillium.

Handling at harvest and during transport is critical.
