Question
The leguminous plants are important in agriculture because :-They are disease resistantThey require very little irrigationThey help in nitrogen fixationCrops of legumes can be produced in a year
Solution
The leguminous plants are important in agriculture for several reasons:
-
Disease Resistance: Leguminous plants are known for their resistance to many diseases that commonly affect other crops. This makes them a safer choice for farmers, as they are less likely to lose their crops to disease.
-
Low Irrigation Requirement: These plants require very little irrigation compared to other crops. This makes them a more sustainable choice, especially in areas where water is scarce.
-
Nitrogen Fixation: Leguminous plants have a unique ability to fix nitrogen from the atmosphere into the soil. This improves the soil fertility and reduces the need for synthetic fertilizers, which are harmful to the environment.
-
Multiple Crops in a Year: Some legumes can be harvested multiple times in a year. This allows farmers to get more yield from the same piece of land, increasing their income.
Therefore, leguminous plants are a valuable asset in agriculture due to their disease resistance, low irrigation needs, ability to fix nitrogen, and potential for multiple harvests in a year.
