Identify, which of the following factors is an essential requirement for the implementation of Green Revolution.
(Choose the correct alternative)
Show Hint
The Green Revolution needed HYV seeds, tractors and threshers, financial help and regular use of chemical fertilizers. The missing circle is chemical fertilizers.
Step 1: Read the diagram:
The diagram has Green Revolution at the centre. Around it are three filled circles: Tractors and Threshers, HYV Seeds and Financial Assistance.
The fourth circle at the bottom is blank. We must pick the factor that fits here.
Step 2: Recall the requirements of the Green Revolution:
The Green Revolution used high yielding variety (HYV) seeds with chemical fertilizers, pesticides and assured water.
Farmers also needed machines and credit, which the diagram already shows.
Step 3: Check option (A):
Regular use of chemical fertilizers is essential. HYV seeds give high yield only when they get fertilizers on time. So (A) is correct.
Step 4: Check the other options:
(B) Use of natural manures is wrong. Natural manures could not give the quick nutrient supply that HYV seeds needed.
(C) A lesser requirement for irrigation facilities is wrong. HYV seeds need more water and assured irrigation.
(D) Traditional seeds is wrong. The Green Revolution was based on HYV seeds, which replaced traditional seeds.
Final Answer:
The factor missing from the diagram is regular use of chemical fertilizers. The correct option is (A).
