ICAR-IIHR Organized Training Programme for Horticulture Students of Sam Higginbottom Institute of Agriculture, Technology and Sciences (SHIATS)

ICAR-IIHR Organized Training Programme for Horticulture Students of Sam Higginbottom Institute of Agriculture, Technology and Sciences (SHIATS)


A special training programme was organized for the students of SHIATS, Uttar Pradesh on 'Advances in Production Technology of Vegetable and Fruit Crops' at ICAR-Indian Institute of Horticultural Research (ICAR-IIHR) from July 6-11, 2015. It was a unique programme, first of its kind, organized for budding students doing under graduate course in horticulture.


This programme was organized as a result of the initiative taken by students themselves by approaching ICAR-IIHR to have a special training programme. The participant-students represented different states of North India. The objective of the programme was to impart the students, knowledge and skills on advanced production technologies of vegetable and fruit crops.



The participants were imparted training on production advanced production technologies of vegetable and fruit crops, of quality vegetable seedlings under protected structures, protected cultivation of vegetable crops, production of quality planting materials of fruit crops, soil and its management aspects under protected cultivation of vegetable and fruit crops, design and fabrication of greenhouse structures/ machineries, detection and management of pesticide residues, handling, packing, storage and processing of vegetable and fruit crops under protected environment and improved production technology of tropical mushrooms. Lecture-cum-discussion, trainers-trainees interface, visit to experimental and demonstration plots, visit to commercial polyhouses, etc., were the modes employed to impart training to the participants.



The trainees were satisfied with the programme and opined that they have learnt many new scientific management practices relevant to the theme. They also informed that the knowledge, skills and motivation gained from ICAR-IIHR through the course content and  from the scientists through their guidance will help them in shaping their career in horticulture arena. Dr B Balakrishna, Mr G A Atheequlla and Dr R Venkattakumar organized this programme.
