EFFECT OF MOLYBDENUM APPLICATIONS ON LEGUMINOUS HAY CROPS IN PRINCE EDWARD ISLAND

Abstract
Seed treatments of molybdenum were found to increase yields of early red clover on three soil types in Prince Edward Island. Plots receiving 8 or more ounces of molybdenum per acre were significantly better than the control plots. Applications of 1000 lb. and 2000 lb. of ground limestone per acre had no effect on the yields of molybdenum-treated clover but the uptake of molybdenum by plants was highest where the 2000 lb.-per-acre rate was applied. The influence of added molybdenum on clover root nodule formation was determined on one soil type. Eight ounces of molybdenum per acre gave a significant increase in the weight of root nodules on the treated plants.
