Influence of deproteinised foliage fluid liquid biofertilizer on nitrate reductase activity of Eleusine coracana plants

Abstract

Deproteinised leaf extracts previously found favourably enhancing plant and fungi growth. Present attempt has been made to observe its influence in enhancing the enzyme nitrate reductase. Crop of Eleusine coracana was cultivated  and  treated  by  deproteined  whey  from  the  leguminous  weed Cassia tora  and  its  influence examined on the  activity of  the  enzyme  nitrate  reductase  by  spectrophotometric method. Cassia tora  crop  was fractionated  for  the  purpose  to  isolate  crude  leaf  protein by  heating the juice  to  90°C  which gave  deproteinised  leaf  juice (DPJ). The crop growth was also compared with other monocotyledonous wheat,  Sorghum and  bajra   crops.  There  was  enhancement of nitrate  reductase  in  wheat  crop  by the application of  non  leguminous  Basella forage DPJ. There  was  lesser  activity  of  nitrate  reductase in  Eleusine  crop  by the influence  of Cassia  tora  DPJ probably because  of  the  deficiency  of  element  molybdenum in  the utilised  red  soil  for  the   growth  of  crops or allelopathy. Length  and  number  of  leaves of  Eleusine crop was  measured.
