HDC project cost: £30,840
The evaluation of yield and quality of commercially available cultivars and new selections/cultivars of Autumn/Winter Cauliflower, Spring Cabbage and Pointed Cabbage cultivars grown in the major Brassica production areas of the UK.
Aims and objectives:
To compare and evaluate the seasonal performance of autumn/winter cauliflower and spring cabbage cultivars for yield, harvesting period and quality in order to provide up to date data for the industry. Comments on disease tolerance, shape, colour and suitability for various market outlets is also recorded. This will be presented via a regularly updated website and grower Open Day/Information Evening providing technical and crop management information.
Heading late September through to early November. Spacing at 25,315/hectare (10,249/acre).
Heading mid November through to end March
Comparing two transplanting dates: 1st and 3rd weeks of July
Comparing spacings of 19,760/hectare (8,000/acre) for the heading period November to end of January. 22,230/hectare (9000/acre) for the heading period of February onwards.
Cultivars maturing over the whole heading period (late October to late March) as requested by the seed companies. Spacing at 21,193/hectare (8580/acre) using replicated plots. Evaluation over several seasons to ensure suitability prior to commercial availability, and then progressing into the main demonstration plots and appropriate Trials.
Transplanting date: Mid September
Harvest dates: mid-January and mid-March
Harvesting cultivars when 2-5 pieces make 250 g in weight (dependent on the season and rate of growth).
Link local meteorological data to results
Make available meteorological records recorded on data loggers alongside, the
cultural, and Trials results on the website.
