Four ways by which GMO’s have been useful for enhanced crop output are –
i. Genetically modified crops are more tolerant to extreme conditions like cold, heat, drought, etc.
ii. Reduction in post-harvest losses.
iii. Some crops are made pest resistant by genetic modification which cuts down the use of pesticides and hence becomes economically and ecologically beneficial.
iv. Helps in increasing the efficiency of mineral usage by plants which maintains the mineral content of the soil and keeps it fertile for longer duration.
