Abstract

  The increasing of use chemical fertilizer causing increase nitrate concentration in irrigation water, this study came to reduce nitrate level in irrigation water to get safe agricultural products. The growth performance of duckweeds (Spirodela polyrhiza) and its removal of nitrate in reclaimed water taken from king TALA dam in Jordan with deferent process were studied. The experiments were conducted in an environmentally controlled growth chamber in Jordan valley authority laboratories.

   Objectives of this study were to analyses nitrate in agricultural growth media contain nitrate concentration 5.0 ppm, 10.0 ppm and 20.0 ppm which covered by duckweeds (Spirodela polyrhiza) and other media contain only nitrate standard 5.0 ppm, 10.0 ppm and 20.0 ppm without duckweed.

   All Growth media were analyzed by using spectrophotometer technique at wave length 220 nm by taking different samples of growth media contain nitrate only, and other growth media contain nitrate with duckweeds (Spirodela polyrhiza). Compared with the treatments without duckweed the concentration of nitrate concentration were reduce 46% in growth media (1) nitrate concentration were reduce 44% in growth media (2), and nitrate concentration were reduce 41% in growth media (3).
