Nutrient management.

Answer 2

Answer ➔ Three basic scientific approaches for increasing the yield of a crop are :

1) Crop production management ⇨It includes proper irrigation and nutrient management and fertilizers. Nutrient management can also be done by crop rotating , inter - cropping and mixed - cropping .

2) Crop protection management ⇨ Plants need protection from weeds , insects , pests and pathogens . It can be done through mechanical methods , biological methods, chemical methods or cultural methods.
