Answer:
Kharif crops are the crops which are sown at the beginning of the rainy season, e.g. between April and May. Rabi crops are the crops that are sown at the end of monsoon or at the beginning of winter season, e.g. between September and October. ... Major Rabi crops are wheat, gram, peas, barley etc.
Manure is an organic substance that is obtained from decomposition of vegetables and animal waste. Fertilizers are inorganic substances manufactured in factories. Manures are relatively less rich in plant nutrients, they only remove general deficiency of soil.
Threshing is the beating of the crop against a stone to separate the grains from the stalk. Winnowing is process of separation of the husk from the seeds by blowing air. The lighter husk flies away and the heavier seeds fall down.
