What are the potential benefits of using genetically modified crops in crop fields?

All of the above

The correct answer is Option (4) - All of the above

Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms (GMO). GM plants have been useful in many ways. Genetic modification has:

(i) made crops more tolerant to abiotic stresses (cold, drought, salt, heat).

(ii) reduced reliance on chemical pesticides (pest-resistant crops).

(iii) helped to reduce post harvest losses.

(iv) increased efficiency of mineral usage by plants (this prevents early exhaustion of fertility of soil).

(v) enhanced nutritional value of food, e.g., golden rice, i.e., Vitamin ‘A’ enriched rice

The use of genetically modified crops in crop fields may:

(1) reduce the harmful effects of fertilisers: Genetically modified crops can be engineered to have better nutrient uptake efficiency, reducing the need for excessive fertilisers and minimizing their negative environmental impact.

(2) maximize yield: Genetic modifications can enhance the resistance of crops to pests, diseases, and adverse environmental conditions, leading to increased crop productivity and higher yields.

(3) be environment-friendly: Some genetically modified crops are designed to be more resilient to pests and diseases, reducing the need for chemical pesticides. Additionally, their increased efficiency in nutrient uptake can reduce the runoff of fertilisers, which can be harmful to the environment.

(4) All of the above: is the correct option.Genetically modified crops offer the potential to address various agricultural challenges, leading to sustainable and environmentally friendly practices while maximizing crop yield and reducing environmental impact.
