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]
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.

Safflower is drought tolerant. [10] The tap root makes moisture from deep soil layers available. [8] Additionally, this tolerance can also be explained by the higher water use efficiency compared to other oil crops such as linseed and mustard. [11] Shortly before and during maximum flowering water requirements are the highest. [8]
Chicory is classified as a drought tolerant ... It has been more widely used during economic ... [65] as the "chicoree", which the French cultivated as a pot herb.
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 ...
It is among the most heat- and drought-tolerant vegetable species in the world and will tolerate soils with heavy clay and intermittent moisture, but frost can damage the pods. In cultivation, the seeds are soaked overnight prior to planting to a depth of 1–2 cm (3 ⁄ 8 – 13 ⁄ 16 in).
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]
