FOREWORD

National Agricultural Education System in India is so vast and diverse that maintaining uniformityand assuring quality is a gigantic task. The ICAR through its Education Division and AccreditationBoard is striving hard to revamp and sustain the agricultural education in India.

The importance of curriculum in any educational programme is self evident. The ICAR, beingthe apex body dealing with agricultural education and research in India, has been in the forefront inupdating the course curricula of different programmes in agricultural universities in the countrythrough Deans' Committees. The Council plays a catalyst's role and provides forum for widespreadinteractions between academic managers, faculty members, students and other stakeholders inagricultural education. The main objective of such interactions is not only updating of academicregulations and curricula for meeting national and global requirements but also uniformlyimplementing the same in agricultural universities.

In the latest revision of UG curricula, we have given emphasis not only on new and emergingareas but also shifting the focus from 'know-how' to 'do-how' so that our undergraduates, aftercoming out of the universities should become job providers rather than job seekers. In thisregard, I would like to specially mention the compulsory work experience for one semester for allundergraduate programmes and also provision of electives to satisfy the aptitude and careerpreference of each student.

I am confident that the revised curricula and model regulations which are being implementednow in all agricultural universities in the country, will equip our graduates to meet the national andglobal challenges of present-day agriculture effectively.

I hope, this publication will serve as a reference material for not only the concerned students andstaff of agricultural education system but also for all those who derive benefits from our graduates.

PREFACE

Education plays a key role in human resource development and therefore, it should be relevant tochanging needs of the society. With the national policies becoming more open and liberalised, theeducation in recent days needed re-orientation more than any time in the past. Keeping this inview, the ICAR, which is vested with the responsibilities of guiding and coordinating agriculturaleducation in the country, took several steps to ensure quality education to meet the ever-changingnational and global scenario in agriculture and allied sciences. The first major step in this directionwas appointment of Third Deans' Committee to review and modify the academic regulations andcourse-curricula for different academic programmes. The second major step was establishment ofan Accreditation Board, which among other things is required to periodically assess curricula ofvarious programmes offered by the National Agricultural Education System(NAES) and suggestmodifications, if needed.

The Third Deans' Committee, after having several meetings and deliberations on therecommendations of various sub-groups, submitted its report to the Council in 1995. In the report,the Committee suggested model academic regulations and curricula for different programmes. Therecommendations of the Deans' Committee were discussed in the annual conference of the Vice-Chancellors of agricultural universities in 1996 and endorsed for implementationsafter refinementand completion of all the formalities.

The Education Division conducted series of meetings of faculty Deans' wherein thread-barediscussions were held on the recommendations of the Third Deans' Committee. In these meetings,not only curricula were given fine tuning but academic regulations, course outlines and other relatedissues were also discussed and finalised. The course-outlines were drawn to meet the expectationsof new millennium. Special emphasis was given to practical training to inculcate skill and confidenceamong the undergraduates. The model academic regulations were developed keeping in view thespecific requirements of the concerned faculty. The faculty-wise recommendations were reviewedin the Joint Meeting of Deans of all faculties and endorsed for implementation. Theserecommendations were placed before the Accreditation Board for approval.

The curricula and course outlines as approved by the Accreditation Board and published faculty-wise can be considered as a model which may be followed by the educational institutions, with somevariation (not exceeding 25%) to suit local needs. It is hoped that the effective implementation ofthe revised curricula will improve the knowledge and skills of our graduates to meet the challengesof the future agriculture.

This publication deals with details as approved by the Accreditation Board for under-graduatedegree programme in agricultural engineering. The new curriculum gives emphasis on some of theemerging areas such as agri-business management, environmental control engineering,standardization and quality control, etc. in addition to electives, project work and in-plant training,all aimed at giving strong orientation towards entrepreneurial skills among the would be agriculturalengineers.

The guidance and encouragement received from Dr R.. S. Paroda, DG, ICAR and Secretary,DARE and Chairman of Accreditation Board is gratefully acknowledged. We would also like tothank all the members of the Accreditation Board for their keen interest and support.

We profusely thank Dr Kirti Singh, Chairman and other members of the Third Deans' Committeefor their untiring efforts in making vide ranging recommendations for revision of curricula andacademic regulations. The Vice-Chancellors" of agricultural universities deserve our thanks for

consideration and acceptance of revised regulations and curricula for implementation without anyreservations.

1. INTRODUCTION

1.1. GeneralEducation is a dynamic process as it should be relevant to changing needs of the Society. Course-curricula is the first and very important component of education. It is the basic requirement to begone through and understood well by a student to gain knowledge and develop skill to perform aspecific function. Therefore, to keep the education relevant, the course curricula should be periodicallyreviewed and modified to suit the ever-changing requirement of the society. The Indian Council ofAgricultural Research (ICAR has been instrumental in affecting curricula changes for differentundergraduate and postgraduate programmes in agricultural sciences in the country since the 50s.

The first major exercise in this regard was made in the late 50's by the then Indian Council ofAgricultural Education, which formulated model curricula for different programmes in agriculturalsciences. After the establishment of the State Agricultural Universities (SAUs), the ICAR has beenmaking periodic exercises for revision of curricula and course outlines in agricultural education.

The first Deans' Committee appointed by the Council submitted its report in 1965. It provideddetailed guidelines for UG education in Agriculture, Veterinary Science and Animal Husbandry,Agricultural Engineering and Home Science. It also made suggestions and recommendations onpostgraduate education.

The Agricultural Universities Review Committee headed by Dr M. S. Randhawa (1977)suggested the constitution of Second Deans' Committee. This Committee headed by Dr N.K.Anant Rao submitted its report in 1981, giving its recommendations for curricula revision inAgriculture, Veterinary and Animal Science, Agricultural Engineering, Home Science, Basic Scienceand Humanities. Most of the recommendations of the Committee were accepted and implementedby the SAUs in the country.

Based on the recommendations made in the Vice-Chancellors' Conference and the Norms andAccreditation Committee of the ICAR, the Third Deans' Committee headed by Dr Kirti Singh wasconstituted by the Council vide notification No. 16-2/91-Edn.II dated llth April,1991. Theconstitution of one of the Committee and its terms of reference (TOR) are given in Appendix-I. TheCommittee constituted sub-groups in all the major areas of agricultural education under theChairmanship of one of the members of the Committee. The sub-groups organized workshopsinvolving Deans and senior faculty members from various colleges, who made detailed study of theexisting educational programmes in the concerned faculties and recommended the course structuresfor different degree programmes for the consideration of the Committee.

The Committee, after considering the views of the sub-groups as well as discussions with theVice-chancellors, Directors of the related institutes, Deans, faculty membersJCAR officials, personsfrom industries, progressive fanners, etc., worked out model requirements for different programmes,in order to bring out uniformity in the system and curricula as far as possible. The Committeesuggested model academic regulation and curricula, but the course outlines were left to be developedby the concerned faculties.

The recommendations of the Deans' Committee were discussed in the annual conference of theVice-Chancellors of agricultural universities in 1996 and endorsed for implementation afterrefinement and completion of all formalities.

The faculty- wise meetings of Deans were held at different places during 1997, wherein academicregulations, curricula, course outlines, infrastructure development, preparation of practical manuals

and text books, refresher courses, etc. were discussed at length keeping in view the guidelinesprovided by the Third Deans' Committee. After careful deliberations, the academic regulations,course curricula and course outlines related to UG programmes were finalised and circulated in theform of proceedings.

The proceedings of the meetings of the faculty Deans were placed before the joint meeting ofDeans of, all the faculties held on 30 April-1 May, 1998. After discussion and endorsement oncommon issues, faculty-wise groups were formed to deliberate on specific issues including normsand standards for undergraduate programmes.

The academic regulations, course curricula and course outlines as fine-tuned after going throughseveral exercises were placed before the third meeting of the Accreditation Board (AB or Board)held on 28 September 1998. The Board approved the same.

The outcome of these elaborate exercises regarding academic regulations, curricula and courseoutlines for various undergraduate programmes are brought out faculty-wise for wide circulationamongst the educational institutions as a model. Here, it may be added that the Third Deans'Committee while suggesting 160 course credits for four years' degree programme, made it clearthat they had no intention of imposing any rigidity on credit requirements, but the variation toaccommmodate the local needs of the university should not be more than 5 credits. Similarly, thecourse outlines finalised and published are only a model and guide to the universities. Based onlocal and regional needs, course outlines can be modified to the maximum extent of 25%, keepingremaining 75% as common.

1.2 Agricultural EngineeringThe meeting of Deans of agricultural engineering faculty was held at the College of Technology

and Agricultural Engineering, Udaipur to develop detailed course curriculum on 2-3 June 1997.The meeting was attended by 18 Deans/ Head of Departments/Senior Faculty Members fromagricultural engineering colleges and 5 officers/scientists from ICAR headquarters(Appendix-2)including Dr Gajendra Singh, DDG(Engg.) and Dr S. L. Mehta, DDG (Edn).

During joint meeting of Deans of all faculties, the agricultural engineering group consisting of14 Deans and faculty members, along with 4 senior agricultural engineers from ICAR headquartersdeliberated on the core issues of UG programme. The discussions were lead by Dr A. Alam, DDG(Engg.) as Panelist and co-ordinated by Dr N.L. Maurya, ADG (Acdn). The highlights of all thesedeliberations, which are directly relevent to the undergraduate programme in agricultural engineering,arc presented in the following sections.

2. REQUIREMENTS FOR UNDERGRADUATEPROGRAMMME

The agricultural engineering education integrates engineering, and agricultural scienceknowledge and skill to develop technology and /or process to raise production and productivity ofagriculture and other farm produce through efficient utilization of natural resources and conservingthe same for future use. Broadly, the activities include efficient utilization of agricultural inputsthrough improved techniques of soil and water management (conservation), efficient implementsand machinery ensuring precision, timeliness and reduced drudgery in farming operations(mechanization), and improving quality of farm produce (processing and value additions).

The agricultural engineering education is dynamic and addresses issues relevant to socialand technological development of the country. The quality and quantum of agricultural inputs,their management techniques, and also quality of farm produce and methods of value additionswould keep on changing with advancement of industrialization in general and economic upliftmentof farmers/processors in particular. It is in this context that the agricultural engineering educationis to be analyzed and course curriculum modified to serve agriculture and the agro-based industries.

There are 21 institutions offering undergraduate degree in agricultural engineering including3 institutions outside agricultural universities system, with annual intake of about 670 students.There has been vide variation in course curriculam from university to university. The course creditshave varied from 150-180, with large variation in credit distribution among different disciplines.Only a few institutions provide flexibility of electives to suit the aptitude and carrier preference ofstudents. Many important and emerging areas are not included or coverage is not adequate.

With the advancement of technology related to agricultural inputs like seeds, fertilizer, waterand pesticides, coupled with the equipment and energy sources for their application, it has becomeessential to optimize these to increase production and conserve natural resources. The agriculturalengineers today are required to provide technology not only for increasing crop production but alsofor reducing post-harvest losses and value additions through processing of produce. Increasingexport opportunities in agriculture and allied industries sector, besides diversification has putadditional demands on agricultural engineering education to meet the growing requirement offood, feed and fiber through efficient management of the costly inputs.

Integrated energy management, controlled application of water, surface covered cultivationand greenhouse, horticulture, agroforestry, aquaculture, value-addition to farm produce, ecology,environmental pollution control and agriculture, standardization and quality control, application ofmicro-processor, agri-business, etc. are some of the new emerging areas which provide major scopeto agricultural engineers. Efficiency, economics, sustainability and competitiveness in internationaltrade are watch words now.

The education in agricultural engineering should, therefore, inculcate skill and knowledge tomeet the challenges to provide increasing employment opportunities to young agricultural engineeringgraduates in academic institutions, development departments, industries, financial institutions, andservice sector. The agricultural engineering curriculum should equip students with in-depthknowledge in theory and practice to meet the challenges of agriculture and industries includingagro-industries for the year 2000 and beyond. A judicious blend of core courses in basic sciencesand humanities, agriculture, basic engineering and agricultural engineering is considered as a prime

requirement. Flexibility in specific specialization through elective courses are other features toprovide intensive and deeper knowledge. A combination of theory, practice, and field-industry-management interactions offer specialized knowledge and skill in a chosen area of agriculturalengineering. In-plant training and work experience is intended to induct professionalism in wouldbe agricultural engineering graduates.
