Abstract
E. antisyphilitica is a plant of bioenergy interest. It is a woody shrub tolerant enough to dry conditions of deserts. Earlier work on this plant revealed it suitable for soils of Rajasthan. This led us to study to enhance its growth and productivity so that its suitability for biofuel production can be ascertained. One of the aspects to increase plant growth is to supplement it with proper nutrients. Hence experiments were conducted with different concentrations of micronutrients manganese, iron and molybdenum in the form of manganous sulphate, ferrous sulphate and ammonium molybdate respectively. Plants were allowed to grow for four months and then harvested and analysed for parameters biomass, hexane extractables, sugars and chlorophylls. Biomass of this plant is useful as raw wood while its latex is a promising hydrocarbon yielding source which was extracted with hexane. Results found were very positive for all the nutrients and best suitable dose were find out for each micronutrient.
