In the context of intensive subsistence agriculture dominated by wet paddy cultivation, consider the following statements:
The correct statements are (A), (B), and (C).
Intensive subsistence agriculture, particularly wet paddy cultivation, has the following characteristics:
(A) Land holdings are very small due to the high density of population: This is correct. In regions where intensive subsistence agriculture is practiced, such as in Southeast Asia and parts of India, the population density is high, and the land holdings are typically small to accommodate the large number of people.
(B) Farmers work with the help of family labour leading to intensive use of land: This is correct. In intensive subsistence farming, family labor is often the main source of workforce, and the land is used intensively to grow crops, particularly paddy.
(C) Farm yard manure is used to maintain the fertility of the soil: This is correct. Farmers in intensive subsistence agriculture often rely on organic fertilizers like farmyard manure to maintain the fertility of the soil, especially in regions where chemical fertilizers are not as widely used or accessible.
(D) The yield per unit area is low, but productivity per labour is high: This statement is incorrect. In intensive subsistence farming, the yield per unit area is generally high due to the intensive use of land and labor. However, productivity per labor is not necessarily high in all cases because labor is often intensive but may not alwa
