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.

    Chemical diversity, genetic profiling and antioxidant activity of Acorus calamus L. accessions from different altitudinal regions of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Chaubey, Pinky; Om Prakash
    In present study the chemical composition of essential oils, total phenol analysis, antioxidant activity, elemental profiling, and genetic variability among the twenty collections of Acorus calamus from different altitudinal zones were evaluated. GC-MS analysis of essential oils of Acorus calamus exhibited the presence of various phenylpropanoids, monoterpenoids and sesquiterpenoids. The yields of essential oils varied from 0.2-1.4% and 0.7- 5.4 % (v/w) the oils of A. calamus leaves and rhizomes respectively. The major components identified in A. calamus essential oils from leaves and rhizomes were β-asarone, α-asarone, Z-methyl isoeugenol, Z-isoelimicin, and shyobunone. The presence of asaronaldehyde could be detected only in the rhizome samples from Chhoi, Nainital (2.4%) and Palpur, Almora collections (0.6%). Several minor constituents were also identified in the oils investigated. The antioxidant activity of rhizomes essential oil was studied by their ability to scavenge free radicals (IC50=22.27 to 61.96 µg/mL), metal chelating activity (29.55 to 159.26 µg/mL) and reducing power activity (21.41 to 61.19 µg/mL) whereas the antioxidant activity of leaf essential oil were evaluated by DPPH radical scavenging method with different IC50 values ranging from10.79 to 106.44 µg/mL in comparison to standard antioxidant. The methanol and hexane extracts were screened for their in vitro antioxidant activity and biochemical assay. All the extracts were also subjected to quantitative analysis of total phenols, flavonoids and orthodihydric phenolic contents. The total phenols, flavonols and orthodihydric phenols in all the methanolic extracts were ranged from 1.67 to 10.42 mg/g gallic acid equivalent, 0.50-27.25 mg/g catechin equivalent and 0.43- 5.50 mg/g catechol equivalent respectively. The antioxidant activity of methanolic extracts of A. calamus were evaluated by the three methods viz. DPPH radical scavenging, metal chelating and reducing power activity in terms of IC50 values were 143.55 to 919.55 µg/mL, 308.57 to 1439.35 µg/mL, 104.62 to 241.81 µg/mL respectively. The antioxidant activity of the hexane extracts also exhibited DPPH radical scavenging activity (IC50 = 113.05 to 1671.05 µg/mL), metal chelating activity (IC50 = 298.46 to 1141.46 µg/mL) and reducing power activity (IC50 = 105.86 to 307.50 µg/mL). In all the cases the activity observed were less than standard compounds BHT, catechin, EDTA and citric acid. The elemental analysis of leaves and rhizomes of A. calamus were studied with the help of atomic absorption spectrometry (AAS). The results exhibited the presence of P, K, Ca, Na, Mg, Mn, Fe, Cu, Cr, Pb, Ni, and Zn. The genetic diversity by simple sequence repeat revealed the monomorphic behaviour of the plant.
