Abstract

Peanut (Arachis hypogaea L.) is a legume crop grown globally and renowned for its nutritional value and diverse applications. Nevertheless, its production is highly vulnerable to water scarcity and the adverse effects of drought stress. The aime of this study was to assess the impact of intermittent water supply on peanut under drought stress (60% field capacity). The results showed that intermittent water supply treatments had a positive effect on peanut growth and yield compared to drought stress. The treatment applied from day 80 until harvest showed significant improvements in pod number plant-1, seed number pod-1, and seed weight, approaching values observed in the control group. Moreover, the oil percentage of seed intermittent water supply treatment increased an approximate 20% compared to the control. Intermittent water supply (stress 60-80 treatment and from day 80 until harvest) improves chlorophyll a content, respiration rate at similar levels to the control. Moreover, applying intermittent water supply treatments from day 80 until harvest helped increase the starch content, particularly the levels of soluble sugars, proteins, and proline, which were comparable to those of the control treatment. These findings highlight the potential of intermittent water supply as an effective irrigation strategy for sustainable peanut production under drought stress.
