2. BRASSICAS 2. <strong>Brassica</strong>s 2.6 Other brassica cultivars Australian Purple Top is the latest brassica to come from the PGG Seeds Ceres breeding programme. It is a Victorian selection from the reliable English-bred Mammoth Purple Top turnip. As its name suggests, Australian Purple Top is a purple top/white base, bulb-type turnip used traditionally in hard, drier regions. The key advances in selecting Australian Purple Top turnip was for improved drought and Diamondback Moth tolerance. Table 5. Sowing dates and grazing times for Australian Purple Top turnip 13 Suggested Sowing Time January to March September to November Rival TURNIP Suggested Sowing Rate Alone (kg/ha) Time to First Grazing Number of Potential Grazings Potential Yield 12-14 weeks 1 6-8 t/ha New York is a white-fleshed, purple-skinned, oval-bulb turnip. New York is distinguished by having a full leaf and a greater leaf-to-bulb ratio than York Globe. The extra leaf-holding has come about from improved tolerance to Turnip Mosaic Virus. Table 6. Sowing dates and grazing times for New York turnip Suggested Sowing Time Suggested Sowing Rate Alone (kg/ha) Time to First Grazing Number of Potential Grazings Potential Yield January to March 1-2 16-20 weeks 1 6-8 t/ha Suggested Sowing Time 1-2 Rival is an early-maturing summer turnip with a tankard-shaped bulb, bred for high leaf production. Rival is ideally used as part of a pasture renovation programme within dairy farms that have a period of dry or a loss of pasture quality through January and February. Rival turnips provide increased volumes of high ME and high protein. Table 7. Sowing dates and grazing times for Rival turnip Suggested Sowing Rate Alone (kg/ha) Time to First Grazing Number of Potential Grazings Potential Yield September to January 1-2 12-14 weeks 1 Up to 10 t/ha
2. <strong>Brassica</strong>s Ace was commercially released in Spring 2005, and feedback has been positive. It is the certified alternative for those farmers who have a place for Rangi rape-types in their summer feed systems. Table 8. Sowing dates and grazing times for Ace forage rape Suggested Sowing Time Mid-October to early November February to March Suggested Sowing Rate Alone (kg/ha) 3-4 3-4 Time to First Grazing 10-12 weeks 10-12 weeks Number of Potential Grazings Potential Yield (depending on number of grazings) 5-8 t/ha 5-8 t/ha Sovereign kale is a medium-tall, late-flowering kale which does not produce large thick stems like giant kales, even at lower plant densities. Sovereign is a better option for mid winter/early spring feed. Sovereign has a high yield potential, although average yields would be more in the 12-14 t/ha range depending on the correct growing environment and crop management. Table 9. Sowing dates and grazing times for Sovereign kale Suggested Sowing Time Late November to late December Suggested Sowing Rate Alone (kg/ha) Time to First Grazing Dominion swede is a traditional high-yielding, yellow-fleshed main crop swede. Dominion has a good record of performance and provides a good example of a traditional first crop, yellow-flesh swede with favourable culinary comments. Table 10. Sowing dates and grazing times for Dominion swede Suggested Sowing Time Late November to early December 1-3 1-2 Number of Potential Grazings Potential Yield 4 18-24 weeks 12-14 + 1 t/ha Suggested Sowing Rate Alone (kg/ha) 1 kg drilled or 1.5 kg broadcast Time to First Grazing Number of Potential Grazings Potential Yield 24-30 weeks 1 ( Possibly the tops 10-14 t/ha in Feb/Mar ) 14 2.
