India In India, the main source of energy is obtained from fossil fuels and the demand for energy is keeps on increasing. The depleting petroleum fuel resources, price hike, non-renewable nature and the emission of pollutant urges the need for the development of an alternative source of fuel which could be easily available, economic and eco-friendly. One among the alternative renewable fuel is “Biodiesel” which is obtained from vegetable oils. Biodiesel is biodegradable, easily available and also offers lubricity which extends engine life. There are about 400 oil yielding crops in India. In India, Rubber tree is primarily cultivated for it latex. But it’s by product namely the Rubber seed oil is not utilized much. In the present study, the physico-chemical properties of rubber seed oil for the potentiality for the production of biodiesel and it was found to be efficient biodiesel resources which meets the ASTM standard for biodiesel . The rubber oil cake was analyzed and it was found to control the weeds, diseases and it is an efficient biofertilizer.

INTRODUCTION
In recent years, the use of biodiesel as alternative source of fuel has been extensively investigated with the objective of ensuring energy security and reducing the environmental impacts of fossil fuel emissions. The biodiesel from vegetable oils increases the cost of food around the world and forests are being cleared to grow the biodiesel crops which compete with the agriculture for land and water. The non-edible oils obtained from the crops grown in non-agricultural and nonforest lands offer a worthy solution to these issues. Biodiesel finds its usage as a standalone fuel (pure form - 100%) in diesel engines or it can be blended with the conventional diesel fuel up to 30% for its use in the compression ignition engines. Rubber seed oil has great potential to become a prominent resource because of its non-edible property. The rubber tree (Hevea brasiliensis) is a perennial plantation crop and is cultivated as an industrial crop since its introduction to Southeast Asia in 1876 [1]. The rubber trees grow at an altitude below 200 m and an average temperature of about 27 or 28°C. Natural rubber producer in the world are Thailand (35%), Indonesia (23%), Malaysia (12%), India (9%), and China (7%) [2]. The annual rubber seed production in India is about 1500 kg per hectare [3]. Hevea brasiliensis is cultivated primarily for its latex and its seed is obtained in high yield as a by-product [4,5] Kerala and Tamil Nadu were the traditional rubber growing states in India. Rubber seeds contain 43% oil [6]. Per 100 g seeds contain 8.5 g water, 17.6 g protein, 48.5 g fat, 22.9 g total carbohydrate, 2.5 g ash, 120 mg calcium and 430 mg phosphorous [7]. The oil cake obtained from the rubber seed after oil extraction is rich in proteins, carbohydrates, minerals, and is a suitable material for the formulation of nitrogenous fertilizer [8]. In India, Rubber trees is grown primarily for its latex and its by product namely the rubber seed oil is not utilized much. In the present study, the physico-chemical properties of rubber seed oil and its blended biodiesel at B10 and B20 proportions were analysed for its potentiality as a biodiesel resources and it was compared with the ASTM standard. Also the rubber oil...
