Question 7

Kerala's agricultural sector is characterized by fragmented landholdings, vulnerability to climate change, and challenges in post-harvest management, especially for small and marginal farmers. To enhance the resilience and profitability of these farmers by integrating them into the agricultural value chain and mitigating risks, which intervention would be *most effective*?

Accepted Answer

B. Strengthening Farmer Producer Organizations (FPOs) for collective bargaining, input procurement, processing, and direct market linkages. — Farmer Producer Organizations (FPOs) enable small and marginal farmers to aggregate their produce, inputs, and bargaining power, effectively overcoming the disadvantages of fragmented landholdings. This collective approach facilitates better access to quality inputs, post-harvest processing facilities, and direct market linkages, thereby integrating them into the agricultural value chain and enhancing their resilience and profitability. While other options offer some benefits, FPOs provide a more comprehensive solution for value chain integration and holistic risk mitigation for small farmers.

Answer

A. Subsidizing chemical fertilizers and pesticides to reduce input costs for all farmers.

Answer

C. Mandating minimum landholding sizes to promote economies of scale in farming operations.

Answer

D. Implementing a universal crop insurance scheme covering all natural calamities without premium contribution.

Accepted Answer

B. The sequence of amino acids in its polypeptide chain. — The primary structure of a protein is defined by the linear sequence of amino acids linked by peptide bonds. Secondary structure refers to local folding patterns like alpha-helices and beta-sheets, tertiary structure is the overall 3D shape of a single polypeptide, and quaternary structure involves multiple polypeptide chains in a protein complex.

Answer

A. The specific three-dimensional arrangement of its alpha-helices and beta-sheets.

Answer

C. The overall spatial arrangement of multiple polypeptide chains in a protein complex.

Answer
