The effects of frequent cutting on the production, root reserves, and behavior of alfalfa
1925
Nelson, N.T.
Experiments indicate that frequent cutting of alfalfa in premature stages results in depleted root-reserves. This causes slow recovery and rate of growth after cutting, low yields of hay, increased weed infestations, and retarded root growth. An increase in the number of crown buds, shoots and main stems occurs as an immediate effect with frequent and early cutting, but the average height and total yields of these top growths is much less than with less frequent cuttings at a more mature stage. Chemical analyses of alfalfa roots and physiological observations show that stored organic foods in the roots of certain plants such as alfalfa have an important influence on their productivity. Both the nitrogen and carbohydrate reserves of the root are decreased by cutting the crop too early.
