YIELD FROM HOP PLANTS
Increase By New Process (N.Z. Press Association) NELSON, March 3. A 20 per cent increase in the yield from hop plants is promised by a simple process in the early cultivation of hop bines proposed by Dr. R. H. J. Roborg, of the Riwaka Hop Research Station, after three years’ research. Dr. Roborg has found a way of identifying high-yielding shoots from among the 10 to 30 shoots which develop from a healthy hop crown in the spring. The choice of shoots is important because only a few shoots are trained to the strings in the middle of spring, the surplus being cut or pulled away. His study showed that highproducing bines could be recognised at training time by the relative lengths of their first four fully-elongated internodes, the section between two nodes or joints on the hop stem. With medium and low-yield-ing shoots a steady increase in length of the first four internodes was found. However, high-producing bines showed internodes numbered 2, 3 or 4 to be shorter or only slightly longer than its predecessor.
