Drought-tolerant crop cultivars resist crop yield losses in drought-prone areas. ... Another example is WUE, which is the amount of biomass (economic yield) produced per unit of water used (Sekhon et al., 2010) and is explained in relation to tolerance to drought and crop yield (Blum, 2005).

1 : a period of dryness especially when prolonged specifically : one that causes extensive damage to crops or prevents their successful growth resistant to drought. 2 : a prolonged or chronic shortage or lack of something expected or desired a drought of creativity.

Some examples of conventional breeding programs for drought tolerance are the development of rice, wheat and Indian mustard varieties tolerant to salt and to alkali soils by the Central Soil Salinity Research Institute in Karnal, India3; the development of maize hybrids with increased drought tolerance4; efforts to ...

Staple food crops like sorghum, cassava, sweet potato, pearl millet, cowpea and groundnut are naturally more drought-tolerant than maize. For centuries, farmers in parts of West Africa have grown maize alongside cassava and sweet potatoes.

Dry farmed crops may include grapes, tomatoes, pumpkins, beans, and other summer crops. These crops grow using the winter water stored in the soil, rather than depending on rainfall during the growing season. Dryland farmed crops may include winter wheat, maize, beans, sunflowers or even watermelon.

Drought tolerance refers to the degree to which a plant is adapted to arid or drought conditions. The plants in dry environments are subjected to random droughts, and it is generally impossible for them to escape from such adverse conditions.

Drought Resistant. ... Plants that have relatively low water requirements or plants that are well adapted to an arid climate are often described as drought resistant or drought tolerant.

Like her, over 80 percent of Kenyans depend on maize as their main staple food to supply their dietary requirements, especially in rural areas. In a neighboring farm, the situation is different. The owner, Gitau Gichuru, planted the SAWA hybrid, an improved maize seed variety designed to withstand drought conditions.
