Trend analysis of harvested area, total production and yield of alfalfa in Vojvodina

Vojvodina Province is a major alfalfa producer in Serbia with approximately 35.7% of total area and total production share of approximately 43.1%. In this paper, the data on area, production and yield of alfalfa observations from 1947 to 2018 and their variation and trends are analysed. The data indicate wide differences in the harvested area, total production and yield of alfalfa. The analysis of data indicates that harvested area and total production of alfalfa have declined over the past decades. Yield trend shows strong yield increase during 1950-1980 followed by periods of declined growth rates to 1990. After 1990s, dry matter yield has been stagnant. However, the increase, decrease and stagnation in yield are not strictly linear.
