The four innovations in farming techniques that led to great productivity are:
1. Crop rotation: This technique involves planting different crops in a specific sequence on the same piece of land. It helps to improve soil fertility, control pests and diseases, and prevent soil erosion.
2. Contour plowing: This method involves plowing across the slope of the land rather than up and down. It helps to prevent soil erosion by slowing down water runoff and allowing it to infiltrate the soil.
3. Disease control: Various methods and techniques have been developed to control and prevent diseases in crops. This may include the use of resistant crop varieties, crop rotation, chemical treatments, and integrated pest management strategies.
4. Gas-powered thresher: The introduction of gas-powered threshers revolutionized the harvesting process by significantly increasing efficiency and reducing labor requirements. Threshers are machines used to separate the grain from the straw or husks of harvested crops.
Note: Underground plowing, flood-resistant seed, and drought-resistant seed are not commonly recognized innovations in farming techniques that have led to great productivity.
To determine the four innovations in farming techniques that led to great productivity, we can go through the options provided and check which ones apply.
1. Underground plowing: This refers to a method of plowing where the soil is loosened and tilled at a deeper level than traditional plowing. However, underground plowing is not a widely recognized innovation in farming techniques, so it can be excluded.
2. Flood-resistant seed: This innovation involves the development and use of crop varieties that have a tolerance or resistance to flooding. This helps prevent or minimize crop damage caused by excessive water. It is considered a valid innovation in farming techniques.
3. Crop rotation: Crop rotation refers to the practice of growing different crops on the same land in sequential seasons or years. This helps prevent the depletion of soil nutrients and reduces the risk of pest and disease outbreaks. Crop rotation is a recognized innovation in farming techniques.
4. Contour plowing: Contour plowing involves plowing along the contours of slopes rather than in straight rows. This helps to prevent soil erosion and retain water. Contour plowing is considered a valid innovation in farming techniques.
5. Disease control: Disease control refers to various methods and strategies used to prevent, mitigate, or manage plant diseases in crops. It encompasses practices such as crop sanitation, the use of disease-resistant varieties, and the application of fungicides. Disease control is a recognized innovation in farming techniques.
6. Drought-resistant seed: This innovation involves the development and use of crop varieties that have increased tolerance or resistance to drought conditions. It helps crops withstand periods of limited water availability. Drought-resistant seed is considered a valid innovation in farming techniques.
7. Gas-powered thresher: A gas-powered thresher is a machine that separates grains or seeds from crops such as wheat, rice, or barley. Although it is a machinery innovation, it is not directly related to farming techniques that led to increased productivity.
Based on the above analysis, the four innovations in farming techniques that led to great productivity are:
- Flood-resistant seed
- Crop rotation
- Contour plowing
- Disease control
