\u201cLarge beds allow for more regular production because they reduce temperature contrasts. The first spring harvests have been slightly delayed, but volumes are rapidly becoming more stable,\u201d said Philippe Lebourg. In addition, the beds are covered with a double mulch: thermal mulch and tarpaulin. The planting was done in double rows at 30,000 crowns\/ha, or 11 crowns per linear metre, mostly with Darzilla (70%), then Vitalim, Terralim, Cygnus and Prius. The biggest adaptation was to the hardware. \u201cWith beds 70 cm high, we had to modify and raise all of the equipment, from tractors to harvest assistance machines,” said Lebourg. The move to a large gap has reduced the costs of setting up the crop as well as harvesting costs. In fact, going from 2.50 m to 3.63 m reduces the length of beds per hectare by 45%, from 4,000 to 2,875 linear metres (ml). There is a direct saving on the purchase of hoops and plastics. This also applies to the cost of harvesting, where there is a 30% gain: less distance covered and more spears to harvest per metre improve the hourly yield of the pickers.<\/p>\n More Info<\/p>\n Also in Morocco<\/p>\n Ridge\u00a0cropping has also been tested in Morocco, in the region of K\u00e9nitra. The area has shallow sandy soils with a concentration horizon of 30cm.\u00a0 In addition, the rise of the water table in winter creates unfavourable conditions for the roots, with the risk of fusarium.\u00a0 This is why ridge cropping is practised on many crops, including fruit trees, mainly stone fruit, on raspberry and, of <\/span>course, on asparagus.\u00a0 Beds are made before planting to position the crowns 25-30 cm above point zero.\u00a0 \u00a0The technique has elicited great interest in the asparagus sector.\u00a0 However, one limitation of the technique is the difficulty of making high beds for white asparagus production.\u00a0 On the other hand, the technique i svery well suited to the production of green asparagus.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":" The Lebourg family’s asparagus is “out of the ordinary”.
