Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Allelopathic effect of four weed species and three varieties of paddy straw extracts on different varieties of wheat (Triticum aestivum L.)”
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-07) Joshi, Bhawana; Rao, P.B.
    The term Allelopathy denotes that body of scientific knowledge which concerns the production of specific biomolecules by one plant, mostly secondary metabolites, that can induce sufferenig in, or give benefit to another plant. This concept suggests that allelochemicals produced by a plant escape into environment and subsequently influence the growth and development of other neighbouring plants. Weeds are the plants which grow where they are not wanted and interfere with germination, growth, productivity and yield of cultivated crops in addition compete with crop plants for nutrients, light and moisture. In the present study, the allelopathic effect of four dominant weed species i.e., Ageratum conyzoides (L.), Chenopodium album (L.), Cynodon dactylon (L.) Pers. and Parthenium hysterophorus (L.) and three varieties of paddy straw, namely Basmati 386, Dubraj, Kalanamak on seed germination, seedling growth (length and dry weight), chlorophyll, proline and total protein contents in PBW-154, PBW-343, PBW-373, PBW-443, PBW-502, RR-21, UP-262, UP-1109, UP-2382 and UP-2425 varieties of wheat (Triticum aestivum L.) and to identify resistant and susceptibility to different weed species. The weed extracts showed both inhibitory as well as stimulatory influence on different parameters (seed germination, seedling growth both in terms of length and dry weight, chlorophyll, proline and total protein contents) in different varieties of wheat. The variety UP-262 was resistant and PBW-502 was susceptible on the basis of per cent reduction in seed germination. Similarly, the variety UP-2382 and PBW-343 in radicle length; UP-1109 and PBW-154 in plumule length; PBW-443 and UP-2425 in radicle dry weight; UP-2382 and PBW-373 in plumule dry weight; and PBW-154 and UP-2425 in total seedling dry weight were resistant and susceptible, respectively. On the basis of the chlorophyll contents (mg/g fresh weight) in different varieties, PBW-343 with C. dactylon (1.97) and UP-2382 with P. hysterophorus (97.16) in Chl-a content; PBW-502 with Kalanamak (4.88) and PBW-502 with P. hysterophorus (92.37) in Chl-b content; UP-2425 with Basmati 386 (0.80) and UP-2382 with P. hysterophorus (92.18) in total Chl (a+b) content and RR-21 with C. dactylon (5.20) was and PBW-154 with P. hysterophorus in chlorophyll ratio (a : b) were resistant and susceptible respectively.. On the basis of proline content (μ mol proline g-1 fresh weight) in different varieties, PBW-373 with C. dactylon (11.18) was resistant and UP-262 with Kalanamak (97.14) was susceptible. The total protein content in different varieties was increased, or remain same or decreased with different weed and paddy straw extracts as compared to control. The total protein content (mg/g fresh weight) was maximum in PBW-373 (7.9) with P. hysterophorus and minimum in UP-1109 with (2.4) with Dubraj. On the basis of total protein content in different varieties, UP-2382 with C. album was susceptible and PBW-502 with C. dactylon and UP-1109 with Basmati 386 were resistant. Thus, the above results indicated that the extract of P. hysterophorus showed maximum effect on all the varieties of wheat compared to others.
