Abstract


Ultisols is soil
which predominate area in Lampung Province. This soil is rather acid until acid reaction, low
in cation exchange capacity (CEC) and organic materials content so that cause inefficient of
fertilization. Zeolite is a available and potential mining products and it is abundant available in
Lampung Province. It can also to improve CEC of soil so that the absorption of soil to fertilizer
can be increased. Besides, it has a high negative charges, so that it can also absorbed of
nutrients and discharged it slowly. A liquid waste of MSG is an agroindustrial waste which
enough potential. The waste contains the high enough organic materials and compound,
especially nitrogen. Low of organic materials at Ultisols, caused needed an input to this
management, for example combination usage of zeolite and liquid waste MSG. Nilam is
plantation crop which have a good enough prospect, and have potency as state resource of
stock-exchange and also can open the new employment. This research arranged in garden
of Lampung State Polytechnic, Hajimena district, with Ultisols, it’s started from July until
January 2006. The research was conducted on factorial method with randomized block design, consist of 2 factors, zeolite application Z0 (0;1,5; 3,0; 4,5 ton/ha), and liqud waste of
MSG (0; 2000; 4000, 6000 l/ha). The data were analysed and then, if the F-test is
significantly different we continued with mean of BNT test. Using zeolite at 1,5 ton/ha level
increased the plant fresh weight and at 3,0 ton/ha level improved the plant dry weight. Using
liquid waste of MSG at of 6000 l/ha level, the highest result of fresh weight and dry weight of
plant. Interaction of zeolite and liquid waste of MSG at combination of 4,5 ton/ha and 2000
l/ha showed the highest result on fresh weight and dry weight of root. The combination of 3,0
ton/ha and 6000 l/ha of zeolite and liquid waste of MSG showed the highest result on the
ratio of root weight.
