In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. [ 1 ] [ 2 ] [ 3 ] Some plants are naturally adapted to dry conditions , surviving with protection mechanisms such as desiccation tolerance , detoxification , or repair of xylem embolism. [ 3 ]
Besides biotic stresses, cowpea also faces various challenges in different parts of the world such as drought, heat, and cold. [60] Drought lowers the growth rate and development, ultimately reducing yield, although cowpea is considered more drought tolerant than most other crops. [61]
Heat tolerance may be displayed alongside cold-hardiness, such as in the American Horticultural Society's "Heat Zones". See Thermoregulation § In plants and Breeding for heat stress tolerance . For drought tolerance , see Drought § Impact on crops and Breeding for drought stress tolerance .
Centro is highly drought tolerant because of its deep root system, making it capable of using groundwater if no other water is available. [8] In the case of drought, the plant adapts by dropping its leaves. [10] Centro is also very capable of enduring waterlogging, flooding and shade while still yielding up to 80% of its optimal amount. [10]
The difference in production costs for mung bean and soybean is due to post-harvest cleaning and/or transportation. Overall, mung bean is considered to have market potential for its drought tolerance, and it is a food crop and not a feed crop, which can help buffer the economic risk from variability in commodity crop prices for farmers.

Agricultural economics is an applied field of economics concerned with the application of economic theory in optimizing the production and distribution of food and fiber products. Agricultural economics began as a branch of economics that specifically dealt with land usage. It focused on maximizing the crop yield while maintaining a good soil ...
Extended drought can cause the failure of small and marginal farms. This results in increased economic, political and social disruption. Water availability strongly influences all kinds of agriculture. Changes in total seasonal precipitation or its pattern of variability are both important.
Xeriscaping is a technique that selects drought-tolerant plants and accounts for endemic features such as slope, soil type, and native plant range. It can reduce landscape water use by 50 – 70%, while providing habitat space for wildlife. Plants on slopes help reduce runoff by slowing and absorbing accumulated rainfall. Grouping plants by ...
