India is the one of the largest producer of rubber in the World. Kerala is the largest producer of rubber in India.

The soils are generally rich in montmorillonitic and beidellitic group of clay minerals. Black soils are most suitable for the cotton crop hence it is also known as black cotton soil. Besides cotton, the soil is suitable for the cultivation of crops like wheat, groundnut, chillies, tobacco and jowar.

Maintenance of proper physical, chemical and biological conditions of the soil is necessary for realizing higher growth, yield and quality of sugarcane. Sugarcane does not require any specific type of soil as it can be successfully raised on diverse soil types ranging from sandy soils to clay loams & heavy clays.

• India is one of the important cotton-manufacturing countries of the world.
  
•  Both short-staple and long-staple cotton is grown in the country.
  
• The cotton textile industry requires raw cotton as principal raw material and chemicals like caustic soda, dyes, arrowroot or starch, etc. for its production. 
  
• The cotton growing regions are Maharashtra, Gujarat, Karnataka, Tamil Nadu, etc.
  

 There are four commercially grown species of cotton, all domesticated in antiquity: Gossypium hirsutum – upland cotton, native to Central America, Mexico, the Caribbean and southern Florida (90% of world production)

India today is the world's 3rd largest producer and 4th largest consumer. Kerala accounts for more than 90 percent of the total rubber production in the country. The total area under rubber cultivation in the state is 5.45 lakh hectares. Rest of the natural rubber is produced in Tamil Nadu and North East states.

1. A total rainfall between 110 and 150 cm is adequately provided the distribution is right, abundant in the months of vegetative growth followed by a dry period for ripening.
2. During the active growth period, rainfall encourages rapid cane growth, cane elongation, and internode formation.
3. But during the ripening period, high rainfall is not desirable because it leads to poor juice quality, encourages vegetative growth, the formation of water shoots and increase in the tissue moisture. It also hampers harvesting and transport operations. 
4. This seems to be the case in regions of South America, South East Asia and some parts of Southern India.

The country has the largest area under sugar cane cultivation in the monsoon reason is India.

Sugarcane grows well in tropical regions with 100-150 cm of rainfall well-distributed throughout the year. However, irrigation is necessary in areas of lower rainfall or even in areas of higher rainfall during the long dry spells.

The major sugarcane-producing states are Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, Bihar, Punjab and Haryana.

Uttar pradesh is the highest producer of sugarcane and then comes Maharastra. Uttar Pradesh accounts for 39% of the total sugarcane production in the country. More than 21 hectares land is under sugarcane cultivation in U.P. 

The residue of sugarcane from which the juice is extracted can be used to prepare Manure.

Thailand is the leading Rubber producing country in the world. Thailand is followed Indonesia and China at the second and third place respectively. India stands at fourth position inRubber production.

Traditionally, rubber is grown in the southern states of Kerala and Tamil Nadu, but an increase in demand for the crop has resulted in a search for other regions where cultivation can be pursued.

The soils are generally rich in montmorillonitic and beidellitic group of clay minerals. Black soils are most suitable for the cotton crop hence it is also known as black cotton soil. Besides cotton, the soil is suitable for the cultivation of crops like wheat, groundnut, chillies, tobacco and jowar.

Shrub is a medium sized woody plant. Cotton is a fibre crop and is a shrub. It is soft fluffy staple fibre which grows in a case. This fibre is yarn into threads. The fibre is almost pure cellulose. India is believed to be the original home of the cotton plant. It is a kharif crop.

The fibre is almost pure cellulose. India is believed to be the original home of the cotton plant. It is a kharif crop.

Soil is the topmost layer of the earth's surface. Each type of soil benefits the plant in different ways. Alluvial soil is rich in potassium. Black soil is rich in calcium, potassium and magnesium. Black soil is best suited for the cotton crops. 

Jute is a native plant of India. It is known as golden fibre. It needs hot and humid climate with average rainfall and temperature. It grows well in alluvial soil regions as it is the most fertile soil. 

Jute is a fibre crop. It is grown for its fibres. Jute is expensive. It is very profitable to our economy. It is the second most important crop after cotton. Its demand is rising in the world making our economy strong. Due to its golden silky colour it is known as golden fibre.

Sugarcane is a grass. It is both tropical as well as sub tropical crop. It grows well in hot and humid climate. India is the second largest producer of sugarcane after brazil. It is the main source of sugar and jaggery.

An agricultural produce which makes the profit in return of selling by grown of crops is known as commercial crop. The Crops are selling to other parties with the object of making the profit from the farming. It is used by the cultivator which grew crops for sale. Cotton, sugarcane, groundnut and tobacco are called commercial crops because they are mainly grown for sale.

Commercial farming is a farming in which an agricultural crop is grown for sale to return a profit. Commercial crop is typically purchased by parties separate from a farm. Tobacco is an example of commercial farming. It is grown largely in semi-arid and rain-fed areas where the cultivation of alternative crops is economically unviable. India is the world’s 2nd largest producer of tobacco.
