Agricultural Practices in India

In swidden (slash-and-burn) agriculture, after vegetation is cut and burned, crops are grown for 2-3 years. The land must then be left fallow for 12-18 years to allow soil fertility and forest cover to regenerate naturally. This long fallow period is essential for sustainable cultivation in tropical regions.

Coconut is a cash crop grown primarily for sale and export (copra, oil, coir). Pulses, wheat, and barley are food crops. However, coconut can also be considered a food crop, creating ambiguity.

These crops are grown in the rainy season.

Rabi crops: Grown in the winter season

The process of supplying water to crops is known as irrigation.

(1) Preparation of soil; (2) Sowing; (3) Adding manure and fertilisers; (4) Irrigation; (5) Protection from weeds; (6) Harvesting; (7) Storage

Sowing of mustard takes place from October to December. So, it is a rabi crop.

Zayad crops Example: Watermelon

This crop requires a light loamy soil with a porous sub-soil that allows the water to drain away.

 As more branching increases the bulk of the crop, it ensures good vegetative growth. Options 1 and 2 cannot be the answer as dwarfness is not preferred for fodder crops. Dwarf (small) varieties do not have long roots and therefore, receive fewer nutrients as compared to varieties with long roots which can fetch nutrients from long distances. Option 4 cannot be the answer as little branching will not increase the bulk of the crop.

 Mixed cropping - It simply means growing of two or more crops simultaneously on the same piece of land. For example, growing leguminous crop with non-leguminous crop. So, if non-leguminous crop cannot take nitrogen from the soil, the other leguminous crop supplies it as it can take nitrogen available in the soil. For example, wheat (non-leguminous crop) + gram (leguminous crop) or wheat (non-leguminous crop) + mustard (leguminous crop). Intercropping - Growing of two or more crops simultaneously in a fixed pattern is known as intercropping. A few rows of one crop and then few rows of other crop. Single cropping - It is a technique of growing a single crop over a wide area. Also known as monoculture. Crop rotation - It is a practice of growing a series of dissimilar types of crops in the same area in sequential seasons for various benefits such as to avoid build up of pathogen or pests that often occurs when one type of species is continuously cropped. Therefore, simultaneously growing of wheat (a cereal) + gram (leguminous crop) on the same piece of land in no fixed pattern is known as mixed cropping.

After harvesting, wheat or paddy stalks are dried in the sun and grains can be separated from the stalks by threshing. 

Paddy is a kharif crop. 

Tea cultivation requires high rainfall (150-250 cm annually), abundant sunshine, gently sloping hills (for drainage), and well-drained acidic soil. Rice requires standing water, jute needs high humidity in alluvial soil, and sugarcane grows in tropical plains with different requirements. These conditions specifically match tea estates in regions like Darjeeling and Assam.

Cash crops are grown primarily for sale rather than subsistence. Cotton, groundnut, and jute are important cash crops. Jowar is a food crop (cereal) primarily grown for human consumption, making it the correct answer.
