Which process is used for improvement of crop?
Answer. hybridisation(i) Crop improvement by hybridisation: Hybridisation refers to crossing between genetically dissimilar plants. This crossing may be intervarietal (between different varieties), interspecific (between two different species of the same genus) or intergeneric (between different genera).
What is a disadvantage of organic farming?
Disadvantages of organic farming Organic food is more expensive because farmers do not get as much out of their land as conventional farmers do. Organic products may cost up to 40% more. Production costs are higher because farmers need more workers . Food illnesses may happen more often.
What are the four advantages of intercropping?
BENEFITS OF INTERCROPPING
- Diversity and stability of fields.
- Reduction in chemical/fertilizer application.
- A complementary sharing of plant resources, such as Nitrogen from N fixing plants.
- Weed suppression, and a reduction in susceptibility to insects and disease.
Is crop rotation good or bad?
Crop rotation also helps to battle against the forces of erosion. Rotating crops helps to improve soil stability by alternating between crops with deep roots and those with shallow roots. Pests are also deterred by eliminating their food source on a regular basis.
What is intercropping and its advantages?
Intercropping is a practice involving growing two or more crops simultaneously on a same piece of land. The main advantage of inter cropping is getting higher returns from the same piece of land which otherwise not be utilized by a single crop. Inter cropping also helps in providing mutual benefits to the crops.
What are the different methods of crop improvement?
Following methods are applied for crop improvement
- Selection.
- Hybridization.
- Polyploid breeding.
- Mutation breeding.
- Plant introduction and acclimatization.
- Tissue culture.
How did agriculture lead to the development of civilization?
When early humans began farming, they were able to produce enough food that they no longer had to migrate to their food source. This meant they could build permanent structures, and develop villages, towns, and eventually even cities. Closely connected to the rise of settled societies was an increase in population.
How was the development of agriculture important to early African civilizations?
Remember: Surplus agricultural production is necessary for development of a civilization. Aside from its annual flood, the Nile was a calm river, easily navigated, at least near its Delta. This made transportation easy, and helped the people of Egypt unite into a single kingdom.
What are the advantages of intercropping and crop rotation in points?
Inter-cropping helps in preventing pests and diseases to spread throughout the field. It also increases soil fertility, whereas crop rotation prevents soil depletion, increases soil fertility, and reduces soil erosion. Both these methods reduce the need for fertilizers.
How does agriculture play a part in civilization?
How does agriculture play a part in civilization? It plays a part in civilization by the community. How are civilized groups different from barbarians? Cause they are in the city and the barbarians are on flat lands.
What is a technique of crop improvement?
Crop Improvement Method # 1. It can be defined as the “process of introducing plants from their growing locality to a new locality.” ADVERTISEMENTS: The introduction of the genotypes from the place where it is grown to an entirely new area. It is the easiest or most common method of crop improvement.
How has agriculture played a significant role in the rise of many civilization?
As food was grown and stored more efficiently, populations increased and settlements grew larger, creating both the incentive and the means to produce even more food on more land. Agriculture spread at different rates, depending on climate and geography.
