      Agronomy JRF (Junior Research Fellowship)

About

Agronomy is the most opted and popular sub-branch of ICAR- PG(JRF). Each year more than 2000 individuals give the exam for PG JRF and NTS scholarships into various institutes of India. Agronomy as a major subject in ICAR JRF examination consists of two subgroups  

1. Agronomy
2. Tea Husbandry and Technology
