Abstract

This research was assigned to study the top crop yield potential and nutritive value of Jerusalem artichoke (Helianthus tuberosus), using a completely randomized designed with three treatments and four replications. The forage was cut at three growing stages where plant high, fresh and dry forage yield and leave/steam ratio were recorded. First and second cut were made when the plant heights were 100-150 and 150-200 cm, respectively. Forage from the third cut was at the early bloom stage (200-250cm). Then the cuts were chopped and sampled and nutrient contents and in vitro DIGESTIBILITY of the samples were determined. The amount of fresh and dry forage yield were 45.20 and 15.95 (ton/h) in first cut, and 64 and 29.85 (ton/h) in the last cut (flowering stage), respectively. Yield of second cut was significantly higher (P<0.05) than the first cut. The crude protein content was the highest (13.42 percent) in the first but the lowest (9.21) in the last cut (P<0.05). The non-fiber carbohydrates contents increased by enhancement of the growing stage (P<0.05). The amount of ash was the highest in the first but the lowest in the last cut (P<0.05). In vitro DMD and OMD were not affected by the growing stage. Results obtained from gas test showed that the cumulative gas yield was the highest at the third cut but the lowest at the first cut (P<0.05). In conclusion, Jerusalem artichoke could be considered as a good potential forage source.
