Statement Based +4 −1

Given below are two statements

Statement (I) : Implementing deficit irrigation strategies in agriculture can diminish crop water productivity under water- limited conditions.

Statement (II) : Deficit irrigation involves deliberately applying less water than the crop's full water requirement during certain growth stages, which can lead to less efficient water use and improved crop yields

In light of the above statements, choose the most appropriate answer from the options given below.

Both Statement (I) and Statement (II) are correct Both Statement (I) and Statement (II) are incorrect Statement (I) is correct but Statement (II) is incorrect. Statement (I) is incorrect but Statement (II) is correct.
