advantage : the yield is high thus bringing profit to the farmers..
disadvantage : it needs the use of fertilizers
Answer:
High Yielding Variety Seeds (HYV seeds) are seeds are of better quality than normal quality seeds. The produce from these seeds is a bit more compared to the normal ones. These seeds are a better option of seeds in order to obtain a healthy and surplus crop.
Advantages:
High Yielding Variety Seeds (HYV) has shorter lifecycle and thereby enables the farmers to go for multiple cropping.
High Yielding Variety Seeds (HYV) needs a lot of water for better yields. The yield per unit area is significantly high.
(HYV) under optimal conditions requires more labour per unit area, and thus help in generating more employment.
Disadvantages:
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.Excessive use of chemical fertilizers and pesticides degrade our environment by killing necessary bacteria present in the soil and hence the soil becomes unusable. If heavy amount of chemical fertilizers, pesticides and water is used then the cost of farming will also increase. the poor farmers are unable to buy HYV seeds, so HYV seeds are of no use to them. Most of the farmers in India are very poor and own very small piece of land, so they can't afford to purchase HYV seeds.
