The correct answer is: d) All of the above.
Small and marginal landholdings are a challenge for agriculture in Tamil Nadu, affecting productivity, mechanization, and profitability.
Productivity: Small and marginal landholdings are less productive than larger landholdings. This is because they are often fragmented, making it difficult to use modern agricultural practices. They also tend to be less fertile, and farmers on small landholdings often have less access to irrigation and other inputs.
Mechanization: Small and marginal landholdings are also less mechanized than larger landholdings. This is because the cost of mechanization is often prohibitive for small farmers. As a result, they often rely on manual labor, which is less efficient and more time-consuming.
Profitability: Small and marginal landholdings are also less profitable than larger landholdings. This is because they are often less productive, and they also have higher costs per unit of output. As a result, small farmers often have difficulty making a profit from their farming operations.
The challenges posed by small and marginal landholdings are a major obstacle to agricultural development in Tamil Nadu. There are a number of policy interventions that could be implemented to address these challenges, such as land consolidation, provision of credit and subsidies, and support for agricultural extension services.
