Abstract


THE PRODUCTIVITY OF Indigofera zollingeriana ON INTERVAL CUTTING.This research aims to know the effect of interval cutting on productivity of Indigofera zollingeriana underneath coconut plantation. The study was done based on completely randomized design (CRD) with 4 treatments and 5 replications. The treatments in this study were : 1) I1 (cutting interval 30 days), 2) I2 (cutting interval 40 days), 3) I3 (cutting interval 50 days) and 4) I4 (cutting interval 60 days). The results showed that the effect of cutting interval significantly (P < 0.01) affect fresh and dry weight leaf and stem, and leaf/stem ratio Indigofera zollingeriana. Cutting interval 60 days have significantly (P<0,01) fresh and dry weight stem of Indigofera zollingeriana than cutting interval 30, 40 days but, there was no significant difference (P>0,05) from the 50 days cutting interval.  Cutting interval 60 days have significantly (P<0,01) fresh and dry weight leaf of Indigofera zollingeriana than cutting interval 30 and 40 days but, there was no significant difference (P>0,05) from the 50 days cutting interval.Cutting interval 50 days have significantly (P<0,01) leaf-stem ratio of Indigofera zollingeriana than cutting interval 30 and 40 days  but, there was no significant difference (P>0,05) from the 60 days cutting interval. It can be concluded that cutting interval 50 days have highly productivity.
