Respons pertumbuhan bibit kelapa sawit (Elaeis guineensis Jacq.) terhadap pemberian fungi mikoriza arbuskular dan cekaman air

Abstract

The objective of this study was to determine ther response of oil palm seedling to the application of arbuscular mycorrhiza fungi (AMF) subjected to water stress.  The treatment design used was a factorial design 2 x 5 arranged in completely rando-mized design.  The first factor was application of AMF i.e. without AMF (control) and inoculation with AMF (mixture of Glomus sp., Entropospora sp., and Gigaspora sp.).  The second factor was water stress i.e. no watering for 0, 7, 14, 21, and 28 days at the end of experiment.  Data obtained were subjected to Bartlett test to examine the treatment variance, and Tukey tests to examine additiveness of the data, and continued by analysis of variance. The results showed that application of AMF increased oil palm seedling growth through the increase in plant height, number of leave,  number of primary root, shoot fresh and dry weight, and percent of root infection.  Duration of water stress significantly affected oil palm seedling growth by decreasing plant height, number of leave, number of primary root, shot and root fresh weight, shoot and root dry weight. However, at any level of water stress, the AMF inoculated seedling had better growth when compared to the control palm.
