Vetiver (Vetiveria zizanioides L.) plants are able to protect the soil from erosion and tolerant of salinity stress. However, at high levels, vetiver show a decreasing growth. The application gibberelin is expected increase growth in stress conditions. purpose this study was evaluate responsiveness production under This research conducted green house Faculty Agiculture, Universitas Sumatera Uta...

The grasses in Thailand were analyzed for the potentiality as the alternative energy crops for cellulosic ethanol production by biological process. The average percentage composition of cellulose, hemicellulose, and lignin in the samples of 18 types of grasses from various provinces was determined as 31.85-38.51, 31.13-42.61, and 3.10-5.64, respectively. The samples were initially pretreated wi...

An experiment was conducted to evaluate the phytoremediation efficiency, growth and biochemical responses of vetiver grass (Vetiveria Zizanioides) in response irrigation with magnetized water [in 3 levels including water, semi-magnetized non-magnetized water] Pb from source Pb-Nitrate salt 4 0, 5, 10 20 mg/L). This study carried out as a factorial arrangement based on completely randomized desi...

The soil–water characteristic curve is an important tool to evaluate the water-holding capacity of unsaturated soil. Plant roots can affect matric suction soil and permeability Therefore, morphological characteristics plant will lead difference in between slope plant-covered slope. This study aims investigate effect Vetiver root morphology on curves hydrological distribution root–soil system wa...

Vetiveria zizanioides, an aromatic plant commonly known as vetiver has been used for various ailments. The essential oil of vetiver root has been shown to possess antioxidant activity. However, antioxidant potential of spent root extract has not been reported. Hence, in the present study, ferric reducing, free radical scavenging and antioxidant activity of two genotypes namely KS1 and gulabi of...

The objective of the present study was to investigate the reduction of mobility, availability and toxicity found in soil contaminated with lead (Pb) and cadmium (Cd) from Santo Amaro Municipality, Bahia, Brazil using two combined methods, commonly tested separately according to the literature: metal mobilization with phosphates and phytoextraction. The strategy applied was the treatment with tw...

Different numerical and analytical models are presently available that provide the tools to predict pollutant and water transfer processes between the soil surface and the groundwater level. Among the existing models, the Hydrus-1D model has been used for years in the prediction of water and pollutants transfer in the unsaturated zone. The main purpose of this paper was to model the movement of...
