प्रश्न
If there is low rainfall in a village throughout the year, what measures will you suggest to the farmers for better cropping?
उत्तर
Poor rainfall poses a threat to the productivity of rain-fed crops.
- These crops then need a supply of water from external sources. Under such conditions, various irrigation systems can be adapted to supply water from different water resources. Some the irrigation methods like a sprinkler, drip and surface irrigation can be used that reduce water wastage and supply the required amount of water.
- Drought resistant and early maturing varieties of crops should be cultivated that have less water requirement.
- Soil should be enriched with more humus content so as to increase the water holding capacity as it retains water for a longer duration.
