Crop variety improvement in Punjab​

Answer 1

Explanation:

Crop variety improvement can be achieved by the process of selection. The criteria for selection are high yield, disease resistance, response to fertilisers, tolerance to climate, etc. ... Nutrient management, irrigation and cropping patterns can help improve crop production.

They offer higher and more stable yields and higher tolerance/resistance to diseases, insect pests, drought, heat, cold, parasitic weeds, and other stress factors. Some varieties also offer large improvements in bread-making quality, nutritional value, and other traits.
