Amelioration of SO2 stress under fertilizer regime in a vegetable crop

Abstract

Urea, superphosphate and potash fertilizers have been used as a nitrogen (N), phosphorus (P) and potassium (K) source of mineral nutrients to recover the SO2 stress in three varieties: Parbhani Kranti, Anamika and Pusa Sawani of a common vegetable crop, A. esculentus (L.). Thirty‐day SO2 exposed crop has been treated with recommended dose of fertilizers individually and in combination. Leaves of 60 days old plants were assessed by the few physiological parameters and compared with untreated plants. Results point out that fertilizer like urea, potash bears high potential of recovery than super phosphate in comparison to untreated ones.
