Modern agriculture is principally focused on varieties bred for high performance under high input systems (fertilizers, water, oil, pesticides), which generally do not perform well under low-input systems. They are high yielders but, they have negative consequences as they are likely to threat sustainability. A new paradigm is required which assures food supply as per demand and being accepted in all aspects such as nutrition, economy and bolster sustainable agriculture. This can be achieved through the breeding of maize for organic conditions or low-input production systems. Organic agriculture has been imperative since the 1990s and currently, there is a surge in demand for varieties specifically adapted to organic or low input conditions. However, breeding programs specific for organic farming would entail major time, resources, and labor investment and to breed organic varieties would require specific testing conditions and different breeding tactics. Different breeding programs have been efficient in maize in organic condition centered on nutrition, economy and local environmental adaptability. This technique helps in resource optimization without compromising food sufficiency for a growing population and thus, fortifying sustainability.
