- Grain yield efficiency intensity
- Gross yield efficiency intensity
- Gross yield efficiency index
- Grain yield efficiency index
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Agronomists and plant physiologists use mathematical indices to evaluate the efficiency of nutrient use, water use, or biomass conversion into economic yield across different genotypes.
Step 3: Detailed Explanation:
In crop physiological evaluation, GYEI stands for Grain Yield Efficiency Index.
This index is used to determine how efficiently a crop genotype converts absorbed nutrients (especially nitrogen or phosphorus) or water into grain yield under stress versus non-stress environments.
It is calculated to identify nutrient-use-efficient and drought-tolerant crop lines.
Step 4: Final Answer:
The correct option is 4, which corresponds to Grain yield efficiency index.
