What is cropping intensity in agriculture?
It refers to raising of a number of crops from the same field during one agricultural year; it can be expressed through a formula. Cropping Intensity = Gross Cropped Area/Net Sown Area x 100.
What is the importance of cropping in agriculture?
Cropping systems have been traditionally structured to maximize crop yields. Conserving soil and water and maintaining long-term soil productivity depend largely on the management of cropping systems, which influence the magnitude of soil erosion and soil organic matter dynamics.
Why is the strategy of increasing cropping intensity important in a country like India?
The strategy of increasing cropping intensity is important in a country like India because: To increase the production of foodgrains for the increasing population and to meet out the demand of raw materials for the agro-based industries.
How is crop intensity measured?
The ratio of cropland to total agricultural land, or the ratio of gross cropped area to net cropped area, has been used for many years as a tool for measuring agricultural or cropping intensity [18, p.
What is the agriculture?
Agriculture is the art and science of cultivating the soil, growing crops and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets. These products, as well as the agricultural methods used, may vary from one part of the world to another.
What are the advantages of cropping system?
➢ Advantages of alley cropping: 1) Better utilization of natural resources. 2) Reduces the cost of cultivation. 3) Improves the soil fertility and productivity. 4) Provides fodder for animals and food for human.
What are the objectives of cropping system?
The objective of any cropping system is efficient utilization of all resources viz. land, water and solar radiation, maintaining stability in production and obtaining higher net returns. The efficiency is measured by the quantity of produce obtained per unit resource used in a given time.
What is meant by gross cropped area?
Gross Cropped Area: This represents the total area sown once and/or more than once in a particular year, i.e. the area is counted as many times as there are sowings in year. This total area is also known as total cropped area or total area sown. This is obtained by deducting Net Area Sown from Gross Cropped Area.
What are the reasons for marginal increase in forest area Class 10?
Reasons for marginal increase in forest area:
- increasing population.
- technological developments.
- expansion of agriculture.
- development of transport and communication facilities.
- overgrazing.
- felling of trees.
How cropping intensity can be increased?
Irrigation: Irrigation has played an important role in raising the cropping intensity in northern states where it has risen considerably. Irrigation helps raise the cropping intensity by enabling raising, of crops during the dry season also.
What is the cropping intensity of Punjab?
The gross cropped area is 7.739 million hectare and the area sown more than once is 3.704 million hectare with the cropping intensity of 186 %.
What are the three advantages of multiple cropping?
Advantages of Multiple Cropping:
- It is a better source of soil utilization.
- It improves yield.
- Increase yield per unit of land.
- Increase the crop production.
- Export increase.
- Foreign exchange increase.
- Costs of input decrease as compared to individual crop growing cost.
- Reduce pest and disease attack.
What is multi cropping and its advantages?
Multiple cropping can increase production and income and has additional benefits—increased crop diversity, improved functioning of agricultural systems, spare land for biodiversity or other uses and reduced use of inorganic fertiliser and pesticides.
Which is most important objective of farming system?
To maintain sustainable production system without damaging resources/environment. achieve agro-ecological equilibrium through the reduction in the build-up of pests and diseases, through natural cropping system management and the reduction in the use of chemicals (in-organic fertilizers and pesticides).
What are the types of cropping system?
The different types of cropping systems include: Mono cropping, Crop Rotation, Sequential Cropping, Inter Cropping, Relay Cropping.
