Influence of salicylic acid and potassium nitrate on plant height and flowering time of groundnut (Arachis hypogaea L.) under varying salinity and drought-induced stresses

This study was conducted to examine the effects of Salicylic acid (SA) and Potassium nitrate (KNO3) on plant height flowering time groundnut (Arachis hypogaea L.) under induced stresses salinity, drought combined salinity drought. Three watering regimes namely; normal, moderate severe were used. For stress, 50 mM NaCl, 100 150 NaCl combination water ?m KNO3 SA separately applied plants water, stresses. The mean at salt concentration 42.29 cm for KNO3, 42.27 SA, compared with 40.98 control (F = 2.73; P ? 0.008). In treatment, 57 DAP (days after planting) 34 in plants. When stress plants, 51 53 treated respectively. conclusion, exogenous application growth regulators such as reduce impact effectively improve yield.
