In 2016 MFSA conducted research to investigate if alfalfa plant stand thinning could result in increased seed yields in declining fields (3+ years old).  Three different  implements were tested:  Joker RT300, Salford RTS and Bourgeault 9200 Cultivator. These were 3 rep Random Complete Block field scale trials which had three treatments:  untreated, 1 pass and 2 passes.
