To bring a new genetically modified crop into the commercial market, it has been estimated to cost USD 136 million over 13 years. [9] This poses a problem for development, as only a small number of companies can afford to develop drought-tolerant crops, and it is difficult for research institutions to sustain funding for this period of time. [9]
Resistance to drought is a quantitative trait, with a complex phenotype, often confounded by plant phenology. Breeding for drought resistance is further complicated since several types of abiotic stress, such as high temperatures, high irradiance, and nutrient toxicities or deficiencies can challenge crop plants simultaneously.
Drought lowers the growth rate and development, ultimately reducing yield, although cowpea is considered more drought tolerant than most other crops. [61] Drought at the preflowering stage in cowpea can reduce the yield potential by 360 kg/ha. [62] Crop wild relatives are the prominent source of genetic material, which can be tapped to improve ...
Such methods include: researching on drought resistant crops, monitoring plant transpiration and reducing soil evaporation. [117] Drought resistant crops have been researched extensively as a means to overcome the issue of water shortage. They are modified genetically so they can adapt in an environment with little water. This is beneficial as ...
Climate resilience is generally considered to be the ability to recover from, or to mitigate vulnerability to, climate-related shocks such as floods and droughts. [7] It is a political process that strengthens the ability of all to mitigate vulnerability to risks from, and adapt to changing patterns in, climate hazards and variability.
Agriculturists in semi-arid regions of Rajasthan follow crop-rotation and use guar to replenish the soil with essential fertilizers and nitrogen fixation, before the next crop. Guar has many functions for human and animal nutrition, but the gelling agent in its seeds (guar gum) is the most important use. [ 2 ]
Vigna aconitifolia is a drought-resistant legume, commonly grown in arid and semi-arid regions of India. It is commonly called mat bean, moth bean, matki or dew bean. The pods, sprouts and protein-rich seeds of this crop are commonly consumed in India. Moth bean can be grown on many soil types, and can also act as a pasture legume.
Teff is a C 4 plant, [5] which allows it to more efficiently fix carbon in drought and high temperatures, and is an intermediate between a tropical and temperate grass. [7] The name teff is thought to originate from the Amharic word ጠፍፋ teffa , which means "lost".
