Question

What is the ideal temperature required for groundnut cultivation?
A. 10℃-20℃
B. 20℃-25℃
C. 25℃-30℃
D. 30℃-35℃

Answer 1

Hint: Groundnut generally grows on a large-scale in the tropical and subtropical countries of the world. It requires a long and warm climate for growing.

Complete answer: Groundnut cultivation can be most favourably grown in a relatively warm temperature. It requires an average temperature of 30°C-35°C during the growing period. Abundance of sunlight is also very favourable for its growth. A well distributed rainfall of 40-125 cm throughout the year is very much for its growth. Groundnut cultivation is seen to be done in the warm latitudes between 40° north and south latitudes. It can be grown at an altitude of 1,050 metres.
Optimum mean temperature to grow groundnut is 30℃ and the growth of the plant ceases at or below 15℃. Well drained sandy loam or somewhat clayey soil is most suitable for groundnut cultivation. The use of insecticides and pesticides are common in groundnut cultivation.

Therefore, from the above analysis, it can be said that option D is the correct answer.

Note: India ranks first position in groundnut production in the world. It is grown covering a total area of 75.48 lakh hectares with total production of 63.87 lakh tons per year. The cultivation of this groundnut is mostly confined to the southern states of the country. Some other countries that grow groundnut in abundance are China, Nigeria, USA, Myanmar and others.
