Carotene and protein contents of alfalfa as influenced by variety and certain environmental factors

Abstract: Physiological factors are important. As alfalfa matures, carotene content is maximum in the pre-bud stage, decreases rapidly from then until about the 1/10 bloom stage, and less rapidly thereafter. Total dry weight and total carotene per culm increase at a fairly uniform rate until after seed pods are formed and then decrease. The per cent oven dry weight increases and the protein content decreases with increasing maturity. The carotene content of alfalfa cut at the 1/10 bloom stage increased 23 per cent from June to October. Some variation occurs during the day and from day to day.
