Rubber is a critical industrial raw material. While an equatorial crop, it is successfully grown in India's humid zones. Learn about the commercial processing of natural latex.
Which of the following pair is not correctly matched.
List I List II
(Crop/Plantation) (Largest producer state)
Correct Answer:
(D)
Rubber Himachal Pradesh
India is the world's 4th largest producer of natural rubber. Kerala accounts for around 75.69% of the total rubber production in the country.
Ques: 2
The largest producer of rubber in India is
Correct Answer:
(C) Kerala
The largest producer of rubber in India is Kerala. 90% of total rubber production in India is produced by Kerala as per 2024 data. Ernakulam, Kottayam , Kozhikode and Kollam are the major rubber producing districts of Kerala. According to data for the year 2024, India Rubber Board is the 3rd largest producer and second in consumption of rubber globally.
Ques: 3
Which tree gives out the latex to obtain natural rubber?
Correct Answer:
(B) Hevea brasiliensis
Hevea tree produces a milk-white latex that contains the natural rubber hydrocarbon present in the form of fine emulsion in an aqueous serum which is then later processed to give natural rubber.
Ques: 4
Consider the following statements:
The natural rubber plantation requires a temperature above 25°C with a moist and humid climate.
The Genetically Modified (GM) rubber plant with MnSOD gene can withstand environmental stresses such as cold and drought.
In India, Tamil Nadu is a top rubber producing state.
Which of the statements given above are correct?
Correct Answer:
(A) 1 and 2 only
Recently, the world's first Genetically Modified (GM) rubber plant developed by Rubber Research Institute was planted in Assam.
The rubber plant is the first of its kind developed exclusively for this region, and is expected to grow well under the climatic conditions of the mountainous northeastern region.
Genetic modification (GM) technology allows the transfer of genes for specific traits between species using laboratory techniques.
The GM rubber has additional copies of the gene MnSOD, or manganese-containing superoxide dismutase, inserted in the plant, which is expected to tide over the severe cold conditions during winter in the northeast.
The MnSOD gene has the ability to protect plants from the adverse effects of severe environmental stresses such as cold and drought.
Natural Rubber is an equatorial crop, but under special conditions, it is also grown in tropical and sub-tropical areas. Conditions required are:
Temperature: Above 25°C with moist and humid climate.
Rainfall: More than 200 cm.
Soil Type: Rich well drained alluvial soil.
Cheap and adequate supply of skilled labour is needed for this plantation crop.
The British established the first rubber plantation in India in 1902 on the banks of the river Periyar in Kerala.
India is currently the sixth largest producer of NR in the world with one of the highest productivity (694,000 tonnes in 2017-18).
Top Rubber Producing States: Kerala > Tamil Nadu > Karnataka.
Ques: 5
Main crop cultivated in India under plantation agriculture is:
Correct Answer:
(A) Tea, Rubber, Coconut, Coffee
The main plantation crops cultivated in India are tea, rubber, coconut, and coffee. These crops are grown on a large scale, often owned and managed by individuals or companies, and are a significant part of India's agricultural sector.
