Step 1: Understanding the Concept:
Tracking the state-wise contribution to the national food basket is a core component of agricultural statistics.
Total food grain production includes cereals (rice, wheat, coarse cereals) and pulses across the Kharif and Rabi seasons.
Step 2: Detailed Explanation:
According to the agricultural production data published by the Ministry of Agriculture and Farmers Welfare for the year 2020-21, the ranking of states from highest to lowest total food grain production is:
1. Uttar Pradesh (B): Always occupies the first position in India, contributing around \( 18\% \) of total national food grains (approx. \( 58 \, \text{million tonnes} \)). This is due to its massive production of wheat and rice in the fertile Indo-Gangetic plains.
2. Madhya Pradesh (D): Occupies the second position (approx. \( 34 \, \text{million tonnes} \)). MP has seen a rapid increase in food grain production, driven by massive expansion in wheat cultivation, along with its dominant position in pulses.
3. Punjab (A): Occupies the third position (approx. \( 30 \, \text{million tonnes} \)). Despite its exceptionally high productivity (yield per hectare), its smaller geographical area compared to UP and MP keeps its total production volume in third place.
4. Rajasthan (C): Occupies the fourth position among these states (approx. \( 26 \, \text{million tonnes} \)), with high production of bajra, mustard, and pulses.
Therefore, the descending order is (B), (D), (A), (C).
Step 3: Final Answer:
The correct descending sequence is (B), (D), (A), (C).
