Abstract:
Pea (Pisum sativum L.) is an important legume crop and consumed all over the world, especially in the developing country because it is a good source of protein. Salicylic acid (SA) is a naturally existing phenolic compound that regulates a large variety of physiological and biochemical processes in plants. This experiment was, therefore, conducted to determine the effects of exogenous application of SA on the yield and its attributes of pea under two different water stress condition, during 2019-20 at Vegetable Research Centre, Department of Horticulture, JNKVV, Jabalpur (M.P.).
The experiment was performed in a split plot design and replicated thrice. Water stress condition i.e. irrigated and water deficit stress conditions were assigned to main plots and five doses of SA (0, 0.25, 0.50, 0.75 and 1 mM) were allocated to sub plots. Water stress reduced number of pods plant-¹, seed weight (g), pod length (cm), pod width (cm), pod yield plant-¹ (g), and pod yield hectare-¹ (q ha-¹) of pea. Results signifies that the exogenous application of SA (especially 0.5 mM) improved all measured traits under both irrigated and water deficit stress conditions except in number of seeds per pod. SA plays a vital role in mitigating drought stress. Recent studies have demonstrated the major role of SA in modulating plant responses to abiotic stresses such as water stress on yield and its component. Hence, SA could be used as a potential growth regulator, for improving pea yield and drought tolerance under water deficit stress conditions.
