A series of trials have been conducted to evaluate the efficacy of Vetiver growing under hydroponic conditions to treat motel effluent, which has been primary treated in septic tanks. Water quality results and management issues are of interest. The aim is to surface irrigate the motel gardens with the treated effluent in a sustainable way. This can be accomplished if excessive nitrogen does not...

Vetiveria zizaniodes (vetiver) is commonly known for its effectiveness in soil and sediment erosion control. It can tolerate to extreme soil conditions and produce a high biomass even growing in contaminated areas. Zea mays (maize) can also produce a very high biomass with a fast growth rate and possesses some degree of metal tolerance. A greenhouse study was conducted to investigate the feasib...

Nitrogen limitation represents a major bottleneck during the revegetation of mine tailings. However, controls over key nitrogen-cycling genes in rhizospheric soils under differential vegetation management remain poorly understood. The abundance and transcriptional activity of nitrogen-cycling genes and the enzymatic activity of nitrogen transformation are mediated differentially during revegeta...

The purpose of the present study was to investigate the limits of irrigationwater salinity and soil water content for growth inhibition of vetiver. Moreover,different models were studied to describe the root water uptake and plant topgrowth under salinity and water stresses in a pot experiment. Irrigation treatmentsconsisted of three irrigation intervals (3, 6 and 9-day). The salinity levels of...

Vetiver, a native of India is known for its perfumery and medicinal value since ancient times, much before the world became familiar with rose scents. The annual world trade in vetiver oil is estimated to be around 250 tons, with Haiti, Indonesia (Java), China, India, Brazil, Japan being the main producers, and USA, Europe, India, and Japan being the main consumers. It is a gift of India t o mo...

Possibilities to combine augmentative biological control using Trichogramma spp. egg parasitoids and conservation through habitat manipulation, for the management of rice leaffolder stemborer pests have received only cursory mention in literature. We reviewed information on use releases manipulation manage leaffolders stemborers rice. Stemborers become a priority since 1990s with research focus...

Vetiver grass was harvested at 4, 6 and 8-week regrowth and were ensiled with cassava peels at ratio 60:40 and 100% without cassava peels. The quality and chemical composition of the silages were assessed. The silages along with fresh unensiled re-growths of vetiver grass were fed to WAD goats in a cafeteria method to determine the coefficient of preference of the diets. Results showed that ens...
