Improvement in Yields or Increase in food production
Following three scientific approaches are adopted in India to obtain high yields from our
agriculture farms:
1. Crop variety improvement
2. Crop production management
3. Nutrient Management
Crop variety improvement
It can be done either by hybridisation or by introducing a gene.
(i) Crop improvement by hybridisation: Hybridisation refers to crossing
between genetically dissimilar plants. This crossing may be intervarietal
(between different varieties), interspecific (between two different species of
the same genus) or intergeneric (between different genera).
(ii) Crop improvement by introducing a gene: This provides the desired
characteristics and results in genetically modified crops.
