Phosphorus and potassium were applied separately at five levels — 0, 60, 120, 180 and 240 pounds per acre — and in all combinations prior to seeding a ladino clover-timothy mixture. Plots were cut four times per season to a height of 3 inches. Forage yields were obtained during 1954, 1955 and 1956 from a seeding made in 1953 on Coaticook silt loam soil at the Experimental Farm, Lennoxville, Quebec.Phosphorus fertilization had no significant effect on clover yields but caused distinct increases in timothy yields in 1954 and 1955. Clover yields increased linearly with increasing levels of potassium up to 120 pounds per acre in 1954 and up to 180 pounds in 1955. In 1956, the increase in yields was a linear function of rates of potassium application. Potassium fertilization depressed timothy yields in 1954 but had no effect in 1955 and 1956. The percentage of clover in the harvested forage tended to increase with increasing rates of potassium and to decrease with increasing rates of phosphorus. The reverse was true for timothy. The chemical composition of each forage fraction is also presented.

Vegetative growth of lingonberries was observed on plants growing in four unsterilized, native-Alaskan substrates: coarsely-ground Lemeta peat, Fairbanks silt loam soil, a mixture of peat and silt loam soil and washed Chena very fine sandy loam soil. Following three growing seasons, plants in the peat treatment showed the greatest increase in vegetative growth as revealed by the number of new stems produced, stem length and dry weight per plant. Leaf size did not differ among substrate treatments. The leaves on plants grown in the peat substrate remained green throughout the entire experiment. The leaves of plants in all other treatments showed varying degrees of chlorosis followed by reddening and necrosis. Differences in concentration of N, P, K, Mn, Fe, Zn and Al in whole-plant tissue samples were recorded. The results indicate lingonberries should be grown in a peat substrate for maximum growth and dry matter accumulation.
