Earthworm Biodiversity in an Arid Region of Rajasthan, India

Among the dirt fauna, worms have a significant job to improve soil surface. The dirt surface assumes a significant job in water holding limit. Night crawlers have a capacity to upgrade soil qualities. It adds to the breakdown of natural issue and discharge plant supplements (Edwards and Bohlen, 1996). Night crawlers are likewise considered as helpful pointer of the strength of soil biological system (Edwards and Bohlen, 1992) regarding their job in soil richness through discontinuity and stirred up the dirt with mineral molecule, improving microbial movement to breakdown plant natural matter.The commitment of worms in soil turnover, structure arrangement and fill in as a fruitfulness enhancer in various way. Night crawlers are valuable in land improvement and natural waste administration (Edwards and Baker, 1992; Lavelle and Martin, 1992; Johnson, 1997; Villenave et al. , 1999). The dissemination and populace thickness of different night crawler species have been related with soil ty pe and agribusiness land use (Haynes et al. , 2003; Sbrina et al. , 2009). The biodiversity of worms is impacted by physical, concoction and organic properties of soil and climatic states of habitats.Earthworm’s biodiversity is legitimately influenced by soil attributes (Edwards and Lofty, 1977). These people group impacting factors are soil pH, natural issue, nitrogen, C/N proportion, soil dampness and soil surface. Biodiversity is considered HR (Heywood, 1996). As of late, numerous scientists considered the biodiversity and appropriation of night crawlers in the various pieces of the world (Blakemore, 2000, 2002, 2003; Change and Chen, 2004,2005; Blakemore et al. ,2006; Sautter et al. , 2006; Ghafoor et al. , 2008).Present investigation was done in Bikaner area, which is situated in Thar desert of Rajasthan extending 28. 01â ° N 73. 19â ° E. . The normal downpour fall around there is 10† to 15† as it were. In this way, climatic conditions are unfriendly for li fe forms. A large portion of its zone is flooded with tube wells and Indira Gandhi channel. Because of unfriendly conditions from a significant stretch, there is as yet a couple of data about biodiversity and environments. The current investigation will uncovered new fundamental data for additional examination on worms and its environment and utilization of night crawlers in horticulture area.
