Sommaire partiel
The present investigation describes the ecological and phytochemical investigation of some Mimosaceous tree species of Bikaner district. Four tree species Acacia nilotica (Linn.) Del, Acacia Senegal (Linn.) Willd., Leucaena leucocephala (Lamk.) de Wit, and Prosopis juliflora (Swartz.) DC Prod have been taken for phytochemical studies. Evaluation of primary metabolites like nutritive contents, amino acid contents, mineral contents, ascorbic acid contents and secondary metabolites like flavonoids (antimicrobial principles) and anitimicrobial screening has been carried out. Plant parts such as leaves, stems and fruits of selected plant species were analysed for phytochemical studies. These plants were collected from three different sites of Bikaner district. (1) Kolayat (2) Lunkaransar (3) Nokha

Climatological Studies
The general climate of Bikaner district is arid with large variation in temperature and has scanty and erratic rainfall. The monsoon months witness small amount of rains. Except during the short rainy season, relative humidity remains very low throughout the year. During the period from January, 2005 to December, 2006 the maximum (86.0 mm) rainfall was recorded in August, 2006 and minimum (0.00 mm) in the month of October to December, 2005 and January, February, May, November and December, 2006. During the period from January, 2005 to December, 2006 average maximum temperature (43.6°C) was recorded in June, 2006 and minimum (5.5°C) in the month of December, 2005. During the period from January, 2005 to December, 2006 the average maximum relative humidity (77.2%) was recorded in August, 2006 while average minimum (21.2%) was recorded in the month of April, 2005.

Soil Analysis
Mechanical, physical and chemical analysis of soil samples collected from three different sites i.e. Kolayat, Lunkaransar and Nokha of Bikaner district were carried out by using the methods of Piper (1957) ; Richards (1954) ; Jackson (1973) ; Subbiah and Asija (1956) ; Olsen’s et al. (1954) ; Kilmer and Alexander (1949) ; Walkly and Blacta (1934) ; Lindsay and Norvell (1978) method
