Effects of Zeolite and Liquid Waste of MSG (Monosodium Glutamate) on Product of Nilam Plant (Pagostemon Cablin Benth) in Ultisols

摘要

Ultisols is soilwhich predominate area in Lampung Province. This soil is rather acid until acid reaction, lowin cation exchange capacity (CEC) and organic materials content so that cause inefficient offertilization. Zeolite is a available and potential mining products and it is abundant available inLampung Province. It can also to improve CEC of soil so that the absorption of soil to fertilizercan be increased. Besides, it has a high negative charges, so that it can also absorbed ofnutrients and discharged it slowly. A liquid waste of MSG is an agroindustrial waste whichenough potential. The waste contains the high enough organic materials and compound,especially nitrogen. Low of organic materials at Ultisols, caused needed an input to thismanagement, for example combination USAge of zeolite and liquid waste MSG. Nilam isplantation crop which have a good enough prospect, and have potency as state resource ofstock-exchange and also can open the new employment. This research arranged in gardenof Lampung State Polytechnic, Hajimena district, with Ultisols, it\u27s started from July untilJanuary 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 ofMSG (0; 2000; 4000, 6000 l/ha). The data were analysed and then, if the F-test issignificantly different we continued with mean of BNT test. Using zeolite at 1,5 ton/ha levelincreased the plant fresh weight and at 3,0 ton/ha level improved the plant dry weight. Usingliquid waste of MSG at of 6000 l/ha level, the highest result of fresh weight and dry weight ofplant. Interaction of zeolite and liquid waste of MSG at combination of 4,5 ton/ha and 2000l/ha showed the highest result on fresh weight and dry weight of root. The combination of 3,0ton/ha and 6000 l/ha of zeolite and liquid waste of MSG showed the highest result on theratio of root weight.
