Is it true that nitrogen fixation happens during lightning?

Nitrogen fixation is the process through which the nitrogen in the air is taken in its molecular form and converted to nitrogenous compounds and these compounds are stored in the plant tissues as proteins. 

It is true that nitrogen fixation can happen during lightning. Lightning is a powerful electrical discharge that occurs during thunderstorms. When lightning strikes, it can split atmospheric nitrogen molecules into individual nitrogen atoms, which can then combine with oxygen to form nitrogen oxides. These nitrogen oxides can dissolve in rainwater and be carried to the soil, where they can be taken up by plants or other organisms.
