Recently the new syllabus for under graduate and post graduate of all Agricultural Universities in India has been implemented. Therefore, the request from the students and staff for objective question bank was tempting to authors to write such type of book. They suggested that the question bank should contains multiple choice answers, fill in the blanks, true or false statements as well as match the pairs based on the new syllabus for Under Graduate and Post Graduate Students of the Agricultural Universities in India. Therefore we have taken this challenge to prepare a book based on the agricultural subjects. The questions are collected from various subject matter specialist based on new syllabus on above points.

CET) Test, Ph.D., ASRB, IRMA, PO, MANAGE and Allied Agricultural Examinations. “Objective Agriculture Science” is designed in such a way that give rapid, easy access to the objective facts of the Agricultural subjects which are mostly important and generally asked for various examinations related to Agriculture and allied subjects.
