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 %).

Abstract

The aims of this study were to determine seed germination rate of some local plant species in two hydroseeding mulches containing different tackifier concentration, as well as to determine the optimal hydroseeding mulch media composition for germinating seeds. This study used seeds of 13 local plant species: two species of Cyperaceae (Cyperus brevifolius, C. javanicus), five species of Leguminosae (Cajanus cajan, Crotalaria pallida, Sesbania grandiflora, S. sesban, Tephrosia purpurea), and six species of Poaceae (Eleusine indica, Paspalum conjugatum, Sorghum timorense, S. bicolor, Sporobolus indicus, Themeda arundinaceae). Two hydroseeding mulch media with different tackifier composition were mixed with seeds of each species and then sowed in pots. Each treatment was repeated three times. Moistened cotton wool was used as control and comparative media for observing seed viability. Seed germination in mulch media was observed during 13 days. The results showed that only 8 of 13 species could be germinated: S. indicus, S. timorense, T. arundinaceae, C. cajan, C. pallida, S. grandiflora, S. sesban, and T. purpurea. The highest germination rate was shown by S. sesban (67%) in M2 medium and the lowest one was shown by T. arundinaceae (2%) in both media. The fastest germination time was recorded for C. pallida and S. sesban seeds that germinated in 2 days after sowing (DAS) in both media, while S. timorense and T. arundinaceae seeds showed the lowest ones in 11 DAS. The fluid M1 medium was optimal for seeds germination of S. sesban (50%) and S. grandiflora (35%), while the thicker M2 medium was optimal for seeds germination of S. sesban (67%) and S. timorense (50%) in 13 DAS. The maximum germination rate was generally reached in 11 DAS.

Abstract

The research aimed to determine pioneer local plant seeds germination and growth on coal postmining soil, and to determine optimal mulch for producing great productivity. The research was conducted in two applications in a coal post mining area, Tanah Laut, South Kalimantan. The used seeds were 5 species of legumes, 3 species of grasses, and 3 species of sedges. Hydroseeding was applied by mixing seeds in mulch and spreading it on soil surface of 400 cm2 plots (1st application) and 10,000 cm2 plots (2nd application). There were five treatments in the 1st application and repeated four times, while in the 2nd, there were six treatments with three times repetitions. Germination rate, seedling density, plant coverage, height/length, and leaf length were observed every three days (1st application). On 60 days after sowing, root length and plant biomass (the 1st), and plant coverage, height and productivity (the 2nd) were measured. The results showed that hydroseeding mulches could be media for pioneer local plant seeds germination and seedling growth especially for Leguminosae. While the buffalo dung could be hydroseeding mulch for Poaceae growth. Although root/shoot ratio of Cyperaceae was higher than other families, Leguminosae root developed longer as shoot growth and well adapted on postmining soil. The hydroseeding mulch composed by 720 seeds per plot and applied 4 cm in depth was optimal based on seed germination percentage. Whereas mulch with 0.2 cm depth in 2nd application showed a higher effectivity for plant growth and productivity.
