Q1.    Explain any one method of crop production which ensures high yield.

Answers (1)

One method used for crop production which ensures high yield is: 

Hybridization: Crops from different areas are picked up with desired traits and then cross-bred. The crop with the desired characteristic is obtained. Also, a gene might be introduced that would provide the desired characteristic. This results in genetically modified crops

Or

Crop rotation: It is the method of growing two or more varieties of crops on the same land in sequential seasons. This method ensures the stability in the soil profile across the field and helps in replenishment of soil nutrient levels. 

Or

Inter-cropping: It is the method of growing two or more varieties of crops having different nutrient requirements on the same land in a fixed pattern.

The factors for which variety improvement is done are: Higher yield, early maturation, less water for irrigation, better quality seeds are produced, fewer fertilizers required, adapts itself to the environmental conditions.
