i - e The crops which are sown in the rainy season are called kharif crops. The rainy season in India is generally from June to September. Paddy and maize are kharif crops. Rice which is a kharif crop which requires high temperature, (above 25 ° C ) and high humidity with annual rainfall above 100 cm. i i - d The crops grown in the winter season (October to March) are called rabi crops.

Availability of precipitation during winter months due to the western temperate cyclones helps in the success of these crops. i i i - b Fertilisers are chemicals which are rich in a particular nutrient. Fertilisers are produced in factories. Some examples of fertilisers are— urea, ammonium sulphate, super phosphate, potash, NPK (Nitrogen, Phosphorus, Potassium). i v - c Manure is the organic matter, mostly derived from the animal excreta or plant waste, except in the case of green manure. The use of manure improves soil texture as well as its water retaining capacity. It replenishes the soil with nutrients. Column A Column B i . Kharif crops e . Paddy and maize i i . Rabi crops d .
