Common vetch ( Vicia sativa L) was harvested and allowed to dry in the open air. The composition of fresh forage in non‐structural carbohydrates varied markedly between years, the contents of sugars and starch in both leaves and stems being much higher in 1990‐91 than 1991‐92. Field drying produced a significant decrease in the amounts of these carbohydrates. The total losses of sugars and starch in hay, expressed as losses of dry matter, ranged from 28 to 15 g kg ‐1 , depending on the year.
