It can be due to certain factors like the hay infusion may have been comprising some endospore, which is resistant to heat or may comprise some kinds of bacteria that can withstand high temperatures.
Because of which, even after heating the infusion for one hour, it did not get influenced by the heat and got the chance to grow when it got optimum temperature again at the time when the sample was left as such.
Plants deficient in nitrogen have thin, spindly stems and their growth is stunted.
