By getting crop nutrition right, the grower brings forward harvest and consistently improves head, curd and leaf quality. This can have a significant, positive effect on marketable yield, produce grade, price and ultimately profitability.
Through crop nutrition practices the farmer is able to influence the external appearance of the brassica, including compactness, vegetable brassica size, weight, and colour.
Deficiencies should always be checked by using leaf tissue analyses. While the brassica grower can adapt nutritional programmes to modify dry matter, sugars and glucosinolates within the harvested produce, these are more strongly influenced by other management choices – particularly cultivar selection. After harvesting, controlled temperature storage is essential to maintain good quality brassica produce.
