Herkolim F1 is a 100% male hybrid and highly suitable for production of white asparagus in a temperate climate. This variety is middle-early and an ideal "yield crop", thanks to its high productivity combined with uniform thick stems. Herkolim is ideal for farms where improved results are required through reducing labour costs. Herkolim also performs well in heated conditions.
Herkolim grows well on all well-drained soils. Herkolim is resistant to stress. Combined with its spear thickness and vigour, this makes Herkolim ideal for replanting. Our own practical experience has shown that Herkolim performs best with a planting density of 4.5 - 6 plants per m1. High planting densities do not usually result in thin stems, but give even higher uniformity and better quality. The recommended planting depth is 18 - 20 cm. Herkolim is ideal for cultivation under black-white plastic sheeting. Good sheeting management and the right harvesting frequency ensure production of high quality asparagus.
The very uniform thickness of Herkolim means more than 60% of production is class 22 - 28 mm. Herkolim produces a premium quality product with straight, smooth, white stems with very few hollow stems or pink discolouration. The product rates high on flavour.
Herkolim has broad, robust and open foliage, which quickly dries in the autumn, so it is less susceptible to mould. These good traits also make Herkolim ideal for organic cultivation methods.
