Course Name : Protected Cultivation And Post Harvest Technologies

Code(Credit) : ASAE 3204(1-0-1)

Course Objectives

To impart knowledge on agro-technique and management of different horticultural crops under protected environmental conditions.

Student will be made aware of the technological changes that are occurring in this field along with pre and post-harvest technology

Learning Outcomes

It will aware students and they will gain knowledge about post-harvest technology which enables storage of agricultural products during the whole year in full quality, identification and elimination of negative processes which may be occur during processes and storage.

Explain the importance of pre-harvest physiology for fruit and vegetables on the long term storage of horticultural crops
