The next promising kind of asparagus that thick spears and high yield and profitability is 'super welcome'. The cultivation techniques for productivity improvement of 'super welcome' are as follows. 1) The feature of 'super welcome' is a thick spears. And yield of 'super welcome' is stable by making the mother stems thick (15-20mm). 2) When the number of the mother stems is large, the abnormal stems in summer increase, and yield decrease. So the mother stems number is 10 per furrow 1m. 3) By pinching position is superior at 160cm, the stalk and phyllome grows thickly, photosynthesis assimilation ability rises, and the yield increases. 4) By additional mother stems in summer, the yield in summer decreases, but the harvest and management working time in summer can be reduced, and the annual yield is equivalent with the high unit price in spring, and profitability is improved.
