Answer:
HYV give rise to short stemmed, stiff strawed plants that respond well to heavy dozes of fertilizers. These dwarf varieties give much higher yields per unit area. The response of traditional varieties to chemical fertilizers is more in terms of vigorous vegetative growth which leads to pre-harvest lodging of the crop.
