Why is rainfall important for kharif crops during the monsoon season?

Correct answer: It provides moisture for sowing and growth

Direct answer: Option B, it provides moisture for sowing and growth. Kharif crops are generally sown with the arrival of the southwest monsoon. Seeds need water to germinate, and growing plants need continued soil moisture. Step by step: monsoon winds bring rain; rain moistens the soil; farmers can sow seeds; water supports germination and plant growth. Option A is wrong because useful rain does not dry crops; lack of rain causes drying. Option B is correct because it states the actual agricultural benefit. Option C is wrong because snow does not normally cover Indian fields during the monsoon. Option D is wrong because ordinary rain does not turn fertile soil into stone. Rice is a useful example of a kharif crop that needs substantial monsoon water, although crop needs can vary. Memory cue: kharif begins with rain; rabi is mainly associated with winter cultivation.
