What are drought-resistant crops?
Drought-resistant crops are varieties of plants that are specially designed or naturally adapted to thrive with minimal water. Drought tolerance refers to a plant’s ability to survive during drought. Some plants are even “drought resistant”, meaning that they can survive long periods with no water at all (such as a cactus). drought tolerant plants still need some water and are simply considered to be “low water” plants.Drought is defined as an exceptionally dry period that deviates from a normal situation and that lasts a long time. The soil then requires more water than is available. Drought is often temporary, unlike dehydration, which is a structural problem.Wilhite and Glantz1 categorized the definitions in terms of four basic approaches to measuring drought: meteorological, hydrological, agricultural, and socioeconomic. The first three approaches deal with ways to measure drought as a physical phenomenon.
What is the best drought tolerant cover crop?
Sorghum species are drought- and heat-tolerant, and they are excellent nutrient scavengers. They have the potential to produce larger quantities of biomass than any other cover crop. Wheat is sensitive to drought and heat stress, which are major environmental drivers affecting crop yields in the Panhandle, a semi-arid region.Staple food crops like sorghum, cassava, sweet potato, pearl millet, cowpea and groundnut are naturally more drought-tolerant than maize.These crops can produce stable yields despite reduced rainfall, ensuring a more reliable food supply. Moreover, they reduce the reliance on irrigation, which is critical as freshwater resources dwindle due to overuse and environmental degradation.
What is the most drought tolerant fruit?
Almonds, figs and olives are the most drought tolerant. Apples, cherries, apricots, pears and plums are somewhat drought tolerant. Nectarines, peaches and citrus need adequate water to survive. Drought-tolerant lines of crops such as peanut, common bean, safflower, chickpea, wheat, tall fescue, soybean, wheatgrass, barley and maize have been developed using conventional breeding techniques.Top five drought-resistant plants: Ceanothus. Euphorbia characias subsp. AGM. Hylotelephium spectabile AGM.The ability of crop to grow satisfactorily under water stress is called drought adaptation. Adaptation is structural or functional modification in plants to survive and reproduce in a particular environment. Crops survive and grow under moisture stress conditions mainly by two ways: Escaping drought and.This has a direct impact on crop productivity. Maize also loses around 15% of its global yield due to drought stress. Therefore, to prevent these yield losses and to maintain maize yields in dry regions, the drought tolerance of maize must be improved [123].Some drought tolerant trees that appear across multiple zones include neem, peepal, jamun, shisham, and coconut. Shrubs such as bamboo, tulsi, and jasmine are also listed for their drought tolerance.
What are the three drought resistant crops grown in Region 4?
Natural Region IV Although NR IV is considered unsuitable for dryland cropping, smallholder farmers grow drought-tolerant varieties of maize, sorghum, pearl millet (mhunga) and finger millet (rapoko). Major dry farming crops are millets such as Jawar, Bajra, Ragi, Oilseeds like Mustard, Rapeseed, and Pulse crops like Pigeon Pea, Gram, and Lentil.Cash Crops Examples Tobacco, coffee, rice, tea, wheat, cotton, indigo, soybeans, and maize are cash crops. All these crops are cultivated in large quantities and exported to other countries that have less yield.
What crop needs the least water?
Here some of the most water-efficient crops include: Cactus and succulents: These plants are well-adapted to arid conditions and can store water in their fleshy tissues, making them highly water-efficient. Quinoa: Quinoa is a drought-tolerant crop that requires less water compared to many other grains. A staple root crop in sub-Saharan Africa, cassava is highly drought-tolerant due to its ability to store water in its roots. Even under prolonged drought, cassava plants can continue to produce starchy tubers, providing a critical food source for millions of people.As a crop, cassava is among the most drought-tolerant and can also tolerate nutrient-depleted and acidic soils.Most specialty crops (such as fruits, vegetables, tree nuts, and medicinal herbs) are more vulnerable to drought than field crops and have a higher value per unit of land/water. They may therefore represent a higher risk for experiencing economic loss in drought if the crop water demand exceeds water supply.
Is corn a drought-resistant crop?
Can Corn Tolerate Drought? Corn is sensitive to lack of water, but some varieties of corn can withstand drought better than others. Often referred to as drought tolerant (DT) corn, these varieties are designed to withstand prolonged dry periods. Droughts are caused by low precipitation over an extended period of time. Atmospheric conditions such as climate change, ocean temperatures, changes in the jet stream, and changes in the local landscape are all factors that contribute to drought.India has experienced drought conditions at some point in almost all its states. Droughts can be broadly classified into four main types based on their causes – meteorological, hydrological, agricultural and socioeconomic. Meteorological drought is caused by rainfall deficiency over an extended period of time.Agricultural Drought in India – Lack of Moisture in Soil The agricultural drought of 2009 serves as a notable example. During this period, West Uttar Pradesh, Madhya Pradesh, and Maharashtra faced rainfall deficiencies of over 20%, severely impacting Kharif crop production.Maize crops grown during summer-rainy season in Asian tropics are prone to face both drought and excess moisture stress due uneven distribution patterns of monsoon rains in the region.
