Answer 2

Ploughing, healthy seeds are heavier than unhealthy seeds, fertility of the soil and two types of crops

Explanation:

The process of loosening the soil by use of a plough is called Ploughing or Tilling.

Healthy seeds are heavier in weight and unhealthy seeds are lighter. So the health seeds would sink, while the unhealthy seeds floated on water.

Sowing of only one type of soil continuously lowers the nutrient content in the soil. So the fertility of the soil goes down.

On the basis of season crops are mainly of two types, Kharif and Rabi.

Kharif crops are monsoon crops and hence sown around June and harvested in September or October. Examples of Kharif crops are rice, bajra, ragi, soybean, maize, cotton, and groundnut.

Rabi crops are sown at the end of November and and harvested in April/May. Examples of Rabi crops are wheat, mustard, barley, peas and sesame.
