"The crop is subtropical in nature. A hard frost is injurious to it. It requires at least 210 frost-free days and 50 to 100 centimeters of rainfall for its growth. A light well-drained soil capable of retaining moisture is ideally suited for the cultivation of the crop." Which one of the following is that crop?1. Cotton2. Jute3. Sugarcane4. Tea

Answer» Correct Answer - Option 1 : Cotton

The correct answer is Cotton.

  • Cotton is grown on a variety of soils across the world. 
  • Deep fertile soil with adequate humus and high water holding capacity and good internal drainage is best suited for growing cotton.
  • Cotton can be grown in places wherever at least 180-200 frost-free days are available.
  • The optimum temperature for germination 20-30 degrees Celsius.
  • Germination will be delayed if the temperature is less than 180 C degrees Celsius.
  • Hence the correct answer is Cotton.

  • The climatic condition required for cotton 
    • Cotton is a tropical crop and it is raised in India as a Kharif crop.
    • Cotton requires uniformly high temperatures between 21 degrees Celsius and 30 degrees Celsius.
    • During October, the day temperature should be above 26 degrees Celsius which helps the ripening and bursting of cotton balls under the sunny skies.
    • Along the growing period of at least 200 frost-free days is also necessary for the plant to mature.
    • Rainfall should be moderate, ranging between 50-75 cm.
    • The cotton plant needs sufficient rainfall in the early stages of growth, but sunny and dry weather is required after flowering.
  • The climatic condition required for Jute
    • The suitable climate for growing jute is a warm and wet climate, which is offered by the monsoon climate during the fall season, immediately followed by summer.
    • Temperatures ranging to more than 25 °C and relative humidity of 70%–90% are favourable for successful cultivation.
    • Jute requires 160–200 cm of rainfall weekly with extra needed during the sowing period.
    • River basins or alluvial or loamy soils are best for jute cultivation.
    • Plain land or gentle slope or low land is ideal for jute cultivation.
    • Since the jute seeds are small in size, land should be prepared for fine tilling.
  • The climatic condition required for Sugarcane
    • Sugarcane needs a hot and humid climate.
    • Temperature ranging between 21°C to 27°C.
    • Very high temperature is harmful to its growth.
    • Cool temperature is needed at the time of ripening.
    • It grows best in areas receiving 75 cm to 100 cm of rainfall.
    • Too heavy rainfall results in low sugar content.
    • Sugarcane grows on well-drained fertile soil.
    • It can grow on a variety of soils including black, alluvial, loamy, and reddish loam.
  • The climatic condition required for Tea
    • Tea needs a wet and humid climate with good rainfall.
    • Tea requires a temperature ranging from 21°C to 29°C.
    • Tea grows well in the regions which receive rainfall between 150-200 cm.
    • The soil should be well-drained for better productivity of tea.
    • Many high-quality tea plants are cultivated at elevations of up to 1,500 m.
