Question

Heavy retentive soil is favorable for which type of crop?

(a) Sugarcane and Rice

(b) Maize

(c) Gram and fodder crops

(d) Cotton

This question was addressed to me during an internship interview.

This key question is from Water Requirements topic in chapter Water Requirements of Crops of Irrigation Engineering

Answer 1

The correct choice is (a) Sugarcane and Rice

Easy explanation: Heavy retentive soils contain 40% clay and tend to be more fertile is suitable for raising crops like sugarcane and rice requiring more water. Gram and fodder crops require less water, suitable in light sandy soil (2-8% clay). Cotton and maize require a normal amount of water.
