Abstract

Leaf NPK fertilizer experiments on pitcher plant (Nepenthes neglecta and ventrata) conducted in May 2008 to March 2009 in a greenhouse, Botany Division, Research Center for Biology-LIPI, Cibinong Science Center, Cibinong. The objective is to study the effect of leaves NPK fertilizer on the growth of the two Nepenthes species tested. Experiments using Random Complete Factorial Design with two factors, namely the two Nepenthes species and threedoses of fertilizer each treatment repeated six times. Growth parameters measured include; long shoot leaves, plant height, number of leaves, number of mature pitchers and growth pitchers. Results showed that the dose of NPK fertilizer provided (2 and 4 ml / lt) have no effect on plant height and number of leaves, but little effect on the number of mature pitchers thanthe control plants. The statistical tests also showed no interaction between the two Nepenthes species with a given dose of fertilizer on the growth of plants. Minimum-maximum temperature recorded in the greenhouse during the experiment was 22.20C and 38.50C. Meanwhile, air humidity between 43,6-64,7%.Key words: Leaf NPK fertilizer, plant growth, pitcher plant

Abstract

The research were carried out to study the potency of Salvinia molesta D.S. Mitchell (Kiambang), Limnocharis flava (L.) Buchenau (Genjer) and Monochoria vaginalis (Burm.f.) Presl (Eceng) for Hg phytoextraction on paddy field contaminated with Hg from illegal mining. The plants were grown on contaminated media from paddy field in Pongkor (68.269 ppm Hg) added by NPK fertilizer (0, 3 and 6 g/pot) and ammonium thiosulphate chelating agent (0, 20 ppm). The result showed that the growth of kiambang,eceng, genjer and padi are significantly different. Chelating agent did not significantly affect the plant growth, meanwhile fertilizer significantly affected the plant growth. Thetreatments resulted in different Hg concentration in the plants. Fertilizer increased plant biomass and so plant Hg content since Hg contents is a function of total biomass and Hg concentration. It can be concluded that based on the criteria of accumulator plant,kiambang is the most potentially Hg accumulator followed by genjer and eceng.Key words: Phytoextraction, Hg, Salvinia molesta, Limnocharis flava, Monochoriavaginalis
