Drought’s Impact on Growth and Strategies to Mitigate its Effects on Potato Cultivation: A review

Abstract

Abstract The potato is the third most widely produced cereal in the world, behind rice and wheat. The contemporary potato is vulnerable to yield loss in prolonged droughts. Droughts are becoming more severe and common as a result of global warming. Because of its shallow root system, potatoes are easily parched. The occurrence of drought and water shortage has substantial ramifications for the production of potatoes, exerting influence on both the volume and quality of potato harvests. Potatoes are a crop that needs a substantial amount of water, since they rely on a regular and sufficient water supply during their whole growth cycle. The presence of drought conditions or limited water supplies might result in many adverse consequences for the cultivation of potatoes. Potato plants are susceptible to experiencing stunted growth and development as a direct result of the water stress that is brought on by drought conditions. The restricted supply of water adversely affects the absorption of vital nutrients by plants, resulting in imbalances and deficits in nutritional levels. These conditions may lead to inhibited development, diminished leaf surface, and a lower quantity of tubers. Water stress circumstances have a considerable negative impact on the total production potential of potato crops. Moreover, the phenomenon of water shortage has a significant impact on the physiological mechanisms of potato plants, specifically in relation to essential functions like photosynthesis and transpiration. A scarcity of water during the tuber bulking phases might lead to a reduction in potato size, hence impacting its commercial worth. The use of effective irrigation systems, such as drip irrigation or precision sprinklers, has the potential to optimize water usage and minimize losses resulting from evaporation. The use of water conservation methods and the adoption of drought-resistant potato cultivars are crucial solutions for mitigating the effects of water shortage on potato farming. Through the use of these procedures, farmers have the ability to augment the resilience of their potato crops and guarantee the attainment of sustainable production, even when faced with conditions of low water availability.
