Hi agriculturists, welcome to another set of questions on agronomy. Read all the questions very carefully before attempting. Today’s test series consists of 50 questions on agronomy based on the previous year’s questions of the Licensure Examination of Agriculturists. Hence, attempting these questions will help you improve your skills for the upcoming examination.

If you do not get a score above 50%, then you can join our Confidence Booster Test Series. To get notes for the Confidence Booster Test Series, you can message us directly or download pdf notes from the Facebook group.

Every day we launch new test series for agriculture students at 3:30 p.m. To get a daily doze of questions in your feed, you can subscribe to our newsletter, join our WhatsApp channel, Messenger Group and Telegram. Or you can also click on the bell icon at the bottom left corner of the screen to receive daily notifications!
