Given below are two statements:

Statement I: Minimum, optimum and maximum temperatures for germination of rice crop are \(10\text{-}12^{\circ}C\), \(30\text{-}32^{\circ}C\) and \(36\text{-}38^{\circ}C\), respectively.

Statement II: Minimum, optimum and maximum temperatures for germination of wheat crop are \(3\text{-}4.5^{\circ}C\), \(20\text{-}25^{\circ}C\) and \(30\text{-}40^{\circ}C\), respectively.

In the light of the above statements, choose the correct answer from the options given below

Question

Which of the following statements is false?

Answer 1

This question compares the cardinal, minimum, optimum, maximum, germination temperatures given for rice and wheat against the standard values used in agronomy.

Statement I (rice): the figures given, about \(10\text{-}12^{\circ}C\) minimum, \(30\text{-}32^{\circ}C\) optimum and \(36\text{-}38^{\circ}C\) maximum, match the commonly cited cardinal temperatures for rice seed germination, so this statement holds up.
Statement II (wheat): the minimum, \(3\text{-}4.5^{\circ}C\), and optimum, \(20\text{-}25^{\circ}C\), figures for wheat are correct, since wheat is a temperate cereal that germinates well in cooler soil than rice. The maximum figure of \(30\text{-}40^{\circ}C\), though, overstates the usual maximum for wheat, which is closer to \(30\text{-}32^{\circ}C\), so this statement is not fully correct.

Since one statement, rice, is fully accurate and the other, wheat, contains an inflated maximum value, the combined judgement has to separate the two rather than accept or reject them together.

Let's summarize:

Rice cardinal germination temperatures as given in Statement I are the standard accepted figures.
Wheat's maximum germination temperature is overstated in Statement II, even though its minimum and optimum values are right.

So the correct choice is that Statement I is correct while Statement II is not correct.

Wheat's maximum germination temperature is overstated in Statement II, even though its minimum and optimum values are right.

So the correct choice is that Statement I is correct while Statement II is not correct.
