- Abstract
This study was conducted at PG and Research Centre in Biotechnology, M.G.R. College, Hosur, Krishnagiri District, Tamilnadu, India during the year 2014 to evaluate the effect of physicochemical properties of soil and water on nutritive value of Azolla pinnata R.Br. Ground water and soil samples were collected from same site of two districts i.e. Krishnagiri and Villupuram, India in winter season. The physico-chemical analysis results reported that Krishnagiri samples possessed more suitable physico-chemical properties with pH 7.25, Mg 4417.8, Ca 1978.3 and K 76.5 mg kg-1 for soil and 7.9, 187.3, 564.6 and 61.6 mg/L-1, respectively for water in case of azolla cultivation than Villupuram district samples. These difference were directly reflected on nutritive value of A. pinnata R.Br. as the culture grown on Krishnagiri samples contained higher amount of nutritive value (crude protein 23.21%, crude vitamins 21.7%, crude fibre 15.9%, crude amino acid 7.9%, phosphorus 0.23%, magnesium 0.49%) than on Villupuram samples (crude protein 22.17%, crude vitamins 19.6%, crude fibre 13.3%, crude amino acid 7.4%, phosphorus 0.18%, magnesium 0.41%) except nitrogen free extract (36.12%) and potassium (3.6%). It is concluded that physico-chemical properties of Krishanagiri soil samples effecively supported the growth and nutritive value of azolla.
