RRL16 recorded maximum oil content and minimum citral percentage. Effect of nitrogen on grass and oil yield was significant. Levels of 1 00 kg N and 50 kg N were on par and Superiorto control in oil yield, but 50 kg N/ha was on par with 100 kg N/ha and control in the case of grass yield. Oil content was maximum at higher nitrogen levels compared to control in most of the harvests.ennullArticle
