Cutting treatments as an aid in the appraisal of varieties of alfalfa
1941
Smith, D. | Graber, L.F.
Data are presented to show that significant differences in field responses of varieties and strains of alfalfa with varying degrees of winterhardiness and tolerance to bacterial wilt disease may not appear for periods of from 5 to 6 years when given a standard cutting treatment. Cutting schedules which included spring clipping were not only detrimental to survival and the production of forage, but they hastened and amplified the differences in these major agronomic characteristics of wilt-tolerant and wilt-susceptible varieties of alfalfa. Aside from cutting treatments, which may be standard for a given locality or region, other cutting schedules designed specifically to augment responses to bacterial wilt disease and to winter losses may prove very useful in appraising new varieties and strains of alfalfa.
