Question

Vandana shiva argues that high yielding varieties are less than half as productive in terms of water use. High yielding varieties of wheat may yield over 40% more than traditional varieties, but require ______________________ as much water:

Answer 1

Answer:

Water required = 2.8 times the water

Step-by-step explanation:

Vandana shiva argues that high yielding varieties are less than half as productive in terms of water use. High yielding varieties of wheat may yield over 40% more than traditional varieties, but require ______________________ as much water:

high yielding varieties are less than half as productive in terms of water use

Let say  Y  Yileding    required   = W  water

40% Extra yield =  1.4 Y

Water required in case of Normal  = 1.4W

But these are less than half as productive in terms of water use

so Water Required = 2.8W

Water required = 2.8 times the water
