DESCRIPTION & OBJECTIVES

The basic purpose of this course is to study seed borne and post harvest diseases and their management. Study of seed born diseases and their impact on seed germination. Effect of biotic and abiotic stresses and storage/ transit conditions on shelf life of seed and perishables. The practical portions include techniques of isolation and identification of microorganisms associated with seeds and their effect on germination. Post harvest losses estimation/ assessment.

 

INTENDED LEARNING OUTCOMES

The outcomes of this course will be:

  1. Students will learn about the seed pathological diseases and their management
  2. Students will be able to lean about post-harvest diseases and their management
  3. Students will learn about the latest developments in the management of seed and post-harvest diseases.
