ASRB NET Agronomy Syllabus

ASRB NET (Agricultural Scientists Recruitment Board National Eligibility Test) in Agronomy is a competitive exam conducted by the Agricultural Scientists Recruitment Board (ASRB) of India for selecting eligible candidates for the position of lecturer/assistant professor in the field of Agronomy. The exam assesses the knowledge of candidates in the field of Agronomy and determines their eligibility for lecturer/assistant professor in the subject.

The ASRB NET in Agronomy is a comprehensive exam that covers topics such as soil science, crop physiology, agroforestry, plant breeding, and seed technology, among others. The exam consists of multiple-choice questions and is held once a year.

ASRB NET in Agronomy is one of the major subjects among candidates. If you are preparing for the ASRB NET Exam, you must consult its syllabus properly. ASRB NET exam syllabus is classified according to 13 different units. you will find on this page syllabus for the ASRB NET Exam.
