What are the ill effects of the HYV seeds?
Hyv seeds require huge fertilizers and pesticides usage. The extended use of chemicals has increased the risk of various health hazards. Recently, the survey held in the areas employing hyv seeds concluded high risk of cancer among the local population.
What disadvantages are associated with using the high yield variety of rice?
Although these crops are known for their high yielding property, the high yield crops also have some disadvantages:
- The high yield crops require more water and fertilizers as compared to the normal varieties of crops.
- They require frequent weeding.
- Continuous use of pesticides.
Are HYV seeds healthy?
High Yielding Variety Seeds (HYV seeds) are seeds are of better quality than normal quality seeds. These seeds are a better option of seeds in order to obtain a healthy and surplus crop. These seeds have good immune system to fight with insects and other diseases.
What are the benefits of using HYV seeds?
High Yielding Variety Seeds (HYV) has shorter lifecycle and thereby enables the farmers to go for multiple cropping. For example, new seeds of rice and wheat complete their lifecycles in 110 and 120 days respectively.
What are the harmful effects of the Green Revolution?

Which among the following is the demerit of HYV seeds?
The major disadvantage associated with HYV seeds is bigger requirement of irrigation facility, chemical fertilizers and pesticides to produce best quality yield. Higher yields are possible only from the combination of HYV seeds, better irrigation facility, good amount of chemical fertilizers and pesticides.
What are the ill effects of the Green Revolution?
What are the problems of Green Revolution?
The Green Revolution has also been widely criticized for causing environmental damage. Excessive and inappropriate use of fertilizers and pesticides has polluted waterways, poisoned agricultural workers, and killed beneficial insects and other wildlife.
What are disadvantages of Green Revolution?
A lack of biodiversity in the global structures of croplands has been established. With one ravaging disease, it can be washed out. It decreases the soil quality used for growing crops.
What are the effects of HYV’s seeds compared to traditional seeds?
The main difference between HYV seeds and traditional seeds is that HYV seeds produce higher crop yield per area whereas traditional seeds are normal quality seeds with regular crop yield. Furthermore, HYV seeds produce high-quality crops while traditional seeds produce a comparatively low-quality crop.
What are HYV seeds write its merits and limitations?
HYV seeds are high-yield variety seeds having a shorter life cycle and thereby enabling the farmers to go for multiple cropping. They need plenty of water to produce the best results, which lower down the level of the water table. They produce much greater amounts of grain on a single plant.
What are the ill effects of Green Revolution in points Class 9?
Solution : (i) Loss of soil fertility due to increased use of chemical fertilizers. (ii) Continuous use of groundwater for tubewell irrigation has reduced the water table below the ground. (iii) The chemical fertilizers, casily soluble in water, can dissolve in the groundwater and pollute it.
