(d) wheat, gram, pea
(iii) Chemical fertilizers
(b) Urea and superphosphate

Explanation:

Kharif crops are grown during the monsoon or rainy season (June to October). They are heavily dependent on rainfall. The main Kharif crops grown in India include paddy, maize, jawar, bajra, cotton, sugarcane, groundnut, pulses, etc.


Rabi crops are agricultural crops that are cultivated in the winter and harvested in the spring. They are sown around mid-November with the onset of the winter season and harvested during the summer from April to May. They require a moderate amount of water for their growth. Examples are wheat, barley, sesame, mustard, gram, and peas.


Manure is partially decomposed organic matter made by recycling animal and plant wastes. Manure is basically animal poop. Examples of manure include rabbit, horse, and chicken poop, bat guano, or cow dung. Urea is also used as manure.


Organic farming enhances the fertility of the soil, prevents soil erosion, and conserves groundwater. It also protects the human and animal kingdoms from the side effects of chemicals and synthetics. Many farm products like vegetables, fruits, herbs, meat, milk, eggs, etc. are produced organically.
