Agricultural Practices in India

Harappans were the earliest people to produce cotton.

The term Rainfed agriculture is used to describe farming practises that rely on rainfall for water.

The line 'It was the driest summer on record and all the crops were destroyed' suggests the answer. 

Food (material obtained usually from plant origin containing vital nutrients). Food grain is the correct option.

Tea plantations flourish on hilly slopes with high rainfall (200-250 cm) and well-drained soil. The slopes prevent waterlogging, which tea plants are sensitive to. Cotton requires moderate rainfall, while jute needs swampy conditions and tobacco grows best in drier climates.

Kharif crops are sown at the beginning of the monsoon (June-July) and harvested in autumn (September-October). Barley and mustard are Rabi crops, grown in winter (October-March). Bajra, rice, maize, and jowar are all Kharif crops.

Masahat is an Arabic term used in medieval Indian land revenue systems that refers to the measurement or area of land. It was the fundamental unit for assessing and calculating land revenue during the Delhi Sultanate period. The other options describe different concepts: infertile land would be called 'banjar' or similar terms, documents of land revenue were called 'qaul' or 'parwana', and excess revenue demands had different terminology.

Paddy (rice) occupies the maximum irrigated area among crops in India. Rice cultivation requires substantial water resources and is primarily grown in irrigated conditions to ensure consistent yields. It covers more irrigated land than wheat, sugarcane, or potatoes due to its staple food status and high water requirements.

Under irrigated conditions, jute is typically rotated with crops like paddy, wheat, potato, pulses, and mustard. The option A (jute-paddy-mustard, jute-paddy-pulses, jute-paddy) represents rotation sequences that are commonly practiced under rainfed conditions rather than irrigated conditions. Irrigated jute cultivation allows more intensive cropping patterns with high-value crops like potato and wheat.

In soil science and agriculture, land that becomes unfit for cultivation due to erosion, waterlogging, or other degradation is termed as 'bad land'. This is standard terminology in land classification.

Rice is a water-intensive Kharif crop requiring substantial rainfall. 100 cm is the standard minimum threshold cited in agricultural geography textbooks. Options A, B, and D (120, 150, 130 cm) represent higher thresholds that are not the standard answer.

Tea, coffee, banana, rubber, and sugarcane are perennial crops grown on large estates called plantations. They are not seasonal crops like kharif (monsoon), rabi (winter), or zaid (summer). Plantation crops require years to mature and produce.

Zaid crops are grown in the short summer season between Rabi (winter) and Kharif (monsoon) seasons. Watermelon, muskmelon, cucumber, vegetables, and fodder crops are classic examples of Zaid crops grown from March to June.

The food production in 1985-86 increased due to all of the above factors.

As one travels from Kolkata to Delhi through the Gangetic plain, the climate becomes drier and more continental. West Bengal (near Kolkata) has high rainfall suitable for rice, while areas toward Delhi have lower rainfall more suitable for wheat. Thus wheat cultivation increases.
