The variance in yield from year to year was reduced, equivalent to a yield increase of 0.8–4.2 bushels per acre. Bushel per acre yield changes were +6.4 for European corn borer resistance, +5.76 for glufosinate tolerance, −5.98 for glyphosate tolerance and −12.22 for corn rootworm resistance.
The use of drought tolerant crops can increase yield in water-scarce locations, making farming possible in new areas. The adoption of drought tolerant maize in Ghana was shown to increase yield by more than 150% and boost commercialization intensity, although it did not significantly affect farm income.
The genetically modified organisms, including potato, tomato, and spinach are applied in the production of substances that stimulate the immune system to respond to specific pathogens. [15] With the help of recombinant DNA techniques, the genes encoded for viral or bacterial antigens could be genetically transcribed and translated into plant cells.
Often, GMOs are labeled “GE,” referring to “genetically engineered.” Crops can be genetically modified to be larger, more resistant to bacteria and disease, more nutritionally dense and ...
Bill Gates has been among the proponents of a second green revolution, saying: [5]. Three quarters of the world's poorest people get their food and income by farming small plots of land...if we can make smallholder farming more productive and more profitable, we can have a massive impact on hunger and nutrition and poverty...the charge is clear—we have to develop crops that can grow in a ...
Borlaug believed that genetically modified organisms (GMO) were the only way to increase food production as the world runs out of unused arable land. GMOs were not inherently dangerous "because we've been genetically modifying plants and animals for a long time. Long before we called it science, people were selecting the best breeds."
To increase yield of cereal crops, the balance of cytokinin is changed. Cytokinin oxidase/dehydrogenase (CKX) is an enzyme that inhibits outgrowth buds in rice, [210] so the gene that codes for this enzyme was knocked out to increase yield. Grains have a high amount of amylose polysaccharide.
Many genetically engineered crops have similar yield alterations due to one or both of the common causes for this. Roundup Ready crops have both: Yield drag due to the modification itself interfering with yield production; and yield lag due to the delay in breeding the best new yield genetics into the RR lines.
