The present study was undertaken to ascertain the morphological responses of a groundnut cultivar K-134, under different water stress regimes characterized as control, mild, moderate and severe stress represented by 100, 75, 50 and 25% soil moisture levels respectively for eight days. Root length increased over control at mild, moderate stress treatments and inhibited at severe stress conditions on all days of sampling. Severe stress treatments had caused significant inhibition in shoot growth on day-4 and 8. The fresh and dry weights of roots and leaves and leaf area decreased over control in all stress treatments except under mild stress on day-4. The changes in theses parameters were dependent on stress severity and duration.

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