Cross-Canada comparison of the productivity of fodder galega (Galega orientalis Lam.) with traditional herbage legumes

A study was conducted across Canada to compare the herbage productivity of fodder galega (Galega orientalis Lam.) to that of traditional forage legume s, in order to assess its agricultural potential. Trials were established a t latitudes ranging from 45 to 56 degreesN with longitudes from 52 degreesW (St. John's, Newfoundland) to 120 degreesW (Dawson Creek, British Columbia ). Herbage productivity was monitored for a maximum of 3 production years. The establishment characteristics of Gale fodder galega were comparable to those of Apica and Beaver alfalfa (Medicago sativa L.) and Altaswede red cl over (Trifolium pratense L.), and somewhat superior to those of Dawn Alsike clover (T. hybridum L.) and Leo trefoil (Lotus corniculatus L.). Anik alfa lfa (M. falcata L.) was far less uniform and vigorous in its establishment than any of the other species. The average annual dry matter yield of fodde r galega ranked third among the seven legumes when averaged over the nine s ites; it produced 5545 (SE 95) kg ha(-1) compared to 3931 (SE 72) kg ha(-1) for Dawn alsike clover, the lowest-yielding crop, and 6673 (SE 114) kg ha( -1) for Apica alfalfa, the highest-yielding. The cumulative dry matter yiel ds indicated that Gale galega is at least as well adapted across Canada as the other legumes, except possibly at Saskatoon where the M. sativa alfalfa s were far superior to all the other legumes in their ability to establish and thrive. The performance characteristics of Gale fodder galega indicate that it has considerable agricultural potential as an additional, perennial , herbage legume for many regions of Canada, except in the semi-arid contin ental climate of the central Prairies where its growth may be Limited by hi gh air temperature and/or insufficient soil moisture.
