Which one of the following statements is NOT correct for high yielding varieties (HYV)?

Take less time for maturing, saving time for raising other crops in the same field

Plants are not very tall, semi-dwarf varieties are stronger and protected from strong winds, but produce less fodder

Very less susceptible to diseases and are not easily attacked by insects

Weeds have to be frequently removed from fields

✅ Correct Option: 3

Option 1 -> HYVs have shorter maturation periods, enabling multiple cropping cycles per year - this is a key advantage.

Option 2 -> HYVs are semi-dwarf varieties with stronger stems that resist lodging, though they produce less straw/fodder - this is accurate.

Option 3 -> HYVs are actually MORE susceptible to diseases and pests, requiring intensive pesticide use - this statement is INCORRECT.

Option 4 -> HYVs require intensive management including frequent weeding for optimal yields - this is true.

Hence, Option 3 -> High yielding varieties are actually highly susceptible to diseases and insect attacks, which is a major drawback. They require significant investment in pesticides and plant protection measures, making them more vulnerable than traditional varieties -> correct
