The Field experiment was conducted at College Orchard, HC&RI, Tamil Nadu Agricultural University and Coimbatore. The variety Pusa Dwarf was subjected to various levels of 100%, 80%, 60%, 40% evaporation replenishment at different growth stages of the crop. Higher content of relative water content (87.70%) and soluble protein (28.60 mg/g) and chlorophyll stability index (85.74%) thus expressed the higher response in nitrate Reductase activity (152.17 µmol CO2 m-2 s-1)at all stage of the crop.
