Abstract

In support of healthy agriculture development to improve farmer’s prosperity status, soil remediation and land conservation efforts maybe relied on the use of biomass of local vegetation. Results of field exploration conducted at Brantas Watershed of East Java indicated that there were at least 154 species of undergrowth scrubs, 47 species of agriculture-plantation crops, and 59 species of road shelter trees. The native undergrowth vegetations had undergone enormous seasonal variations. Biomass of predominance vegetations, e.g. Psophocarpus tetragonolobus, Phaseolus lunatus, Flemingia, Mimosa somian, Acacia villosa, Cassia mimosoides, Mucuna could potentially be used as organic matter sources to improve availability of nitrogen and phosphorus in soils. The amount of nitrogen and phosphorus contributed of the plant biomass significantly correlated with quality of the biomass.

Abstract

The potential role of a macrohydrophyte plant (Vetivera zizanioides) and four semihydrophyte plants (Ipomoea aquatica, Cyperus iria, Commelina nudiflora, Oryza sativa) as remediators of liquid waste of tapioca industry was tested in a glasshouse for 35 days under conditions that resemble to wet and polyculture systems. Results showed that all type of plants grew normally on media containing tapioca liquid waste. Total biomass of I. aquatica and polyculture grown in wet conditions were 32.35 g and 38.44 g, respectively. These were higher than those of control (30.53 g and 36.39 g). Those of V. zizanioides, C. iria, C. nudiflora and O. sativa were inversely observed. However, V. zizanioides showed the highest tolerance index value (120.99%) compared to that of I. aquatica (91.21 %), C. iria (56.62 %), C.nudiflora (89.63 %), O. sativa (83.13 %), and polyculture (62.25 %).
