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.

    Nutrient status of soils of Almora district Uttarakhand and its correlation with soil properties
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-10) Nishad, Premsagar; Tandon, Shishir
    An experiment was conducted to analyze the general soil properties, status of available macronutrients (N, P K and S) and to study the relationship between soil properties and macronutrients. Soil samples (0-15cm depth) were collected from 80 different location of Almora district of Uttarakhand. Different methods of analysis of soil were employed to know the availability of N, P, K and S. Available Nitrogen was analyzed by alkaline KMnO4 method, available phosphorus by Bray’s method, AB-DTPA method, Mehlich-3 method and Morgan method, available Potassium was analyzed by Ammonium acetate, AB-DTPA, Mehlich-3 and Morgan methods and Available Sulphur was analyzed by CaCl2 method. The color of soil samples of entire study area were, grayish brown, brown, light brown, weak red, dark brown, pale brown, light yellowish brown, light olive brown, olive yellow, olive grey, light yellowish brown, pale olive, olive grey, reddish grey and dark grey brown. The soil texture of entire study area was from coarse texture to medium texture. Soil was found to be acidic with soil pH and EC ranging from 5.15 – 6.97 and 0.012 - 0.952 dSm-1 with overall mean value of 6.26 and 0.186 dSm-1, respectively. The soils were medium to high in organic carbon content and ranged from 0.09- 1.90% with overall mean value of 0.99%. The percent organic matter content in soils ranged from 0.16- 3.27% with overall mean value of 1.71%. The percent calcium carbonate content in soils of entire study area ranged from 1.07 – 2.96% with mean value of 2.03%. The available nitrogen in soils ranged from 99.10 - 244.61 kg ha-1 with overall mean of 148.33 kg ha-1. The available phosphorus content extracted by Bray’s method, AB-DTPA method, Mehlich-3 method and Morgan method ranged from 12.43 – 22.35 kg ha-1, 11.64 - 63.62 kg ha-1, 21.35 – 55.93 and 20.13– 69.16 kg ha-1, respectively. Available potassium content ranged from 78.18 – 317.52 kg ha-1, 114.38-296.60 kg ha-1, 90.64-164.74 kg ha-1 and 97.39 - 197.57 kg ha-1, when extracted by Ammonium acetate, AB-DTPA, Mehlich-3 and Morgan methods respectively. The soil available Sulphur ranged from 10.19 - 90.58 kg ha-1 with mean value of 38.26 kg ha-1. No significant correlation was found between soil properties and macronutrients in 18 location soils. At 62 locations, Organic Carbon had significant and positive correlation with available N. and S. In sixty two location soils also showed positive and significant correlation with available nitrogen and potassium with soil pH and EC. On the basis of calculated nutrient indices, the soils under study were found to be low in extractable nitrogen, low to medium in extractable phosphorus, low to high in extractable potassium, low in calcium carbonate and high in sulfur content.

    Phytochemical analysis and evaluation of biological activities of Hedychium coronarium J. Koenig and Hedychium coccineum Buch.-Ham. ex Sm.
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Arya, Sushila; Ravendra Kumar
    In the present study, the variability in chemical constituents, isolation, biological property of essential oils, oleoresins and isolated compounds of Hedychium coccineum Buch.-Ham. ex Sm. And H. coronarium J. Koenig collected from different locations and seasons of Kumaun, Uttarakhand, India were evaluated. Essential oil extracted by Clevenger type apparatus and oleoresins prepared in various solvent by cold percolation method. Essential oils and oleoresin composition were analyzed by GC-MS. Isolation of the compounds done by chromatographic techniques (TLC, Column etc.) and characterized by spectroscopic techniques (MS, FT-IR, 1 H NMR, 13 C NMR and DEPT-135 etc.). Biological activities such as nematicidal, insecticidal, herbicidal, antifungal and antibacterial of essential oils, oleoresins and isolated compounds performed by using standard protocols. 7-Hydroxyfarnesen, α-farnesene, α-pinene, (-)-spathulenol, β-pinene, davanone B, (E)-nerolidol, bornyl acetate and 1,8-cineole were identified as major component in H. coccineum aerial and rhizome part essential oils. (Z)-6, (Z)-9-pentadecadien-1-ole, 1,8-cineole, α-terpineol, (Z)- caryophyllene, camphor etc were identified as major components in H. coccineum oleoresins. 1,8- cineole, coronarin E, α-terpineol, α-pinene, (Z)-caryophyllene, terpinen-4-ol, caryophyllene oxide and bornyl acetate were identified as major component in H. coronarium altitudinal essential oils. n-Hexadecanoic acid, trans-13-octadecenoic acid, photocitral B, pentadecanoic acid, coronarin E, α-pinene etc were identified as major component in H. coronarium altitudinal oleoresins. Similarly, 1,8-cineole, α-pinene, linalool, α-terpineol, caryophyllene, terpinen-4-ol and, coronarin E were identified as major component in H. coronarium seasonal essential oil. Total phenolics, flavonoid and orthodyhydric phenol contents measured for H. coronarium seasonal oleoresins. Isolated compounds characterized as Compound #01 (coronalactosides I); Compound #02 (isolinariin A); Compound #03 (hedychilactone A) and Compound #04 ((E)-labda-8(17), 12-dien-15(16)-olide). Essential oils, oleoresins and isolated compounds were studied for their nematicidal and egg hatching process at different concentrations against M. incognita with significant results. Oils, oleoresins and compounds also tested against S. litura by using leaf dip method. Variable and significant results were observed for insecticidal activity at different concentration. The herbicidal activity was determine in term of inhibition of seed germination, root length and shoot length at different concentration against radish seeds, R. raphanistrum. All the essential oils, oleoresins and isolated compounds showed moderate to strong herbicidal potential in a dose dependent manner. Antifungal activity was evaluated against F.oxysporum and C. lunata in term of inhibition of mycelia growth by using poison food technique. Essential oils, oleoresins and isolated compounds were affected against F.oxysporum and C. lunata at variable concentration. Essential oils of H. coccineum showed significant antibacterial activity against S. aureus and S. Typhi by using disc diffusion method. The results showed that geographic origin and seasons greatly influenced the chemical composition of essential oil/ oleoresin of Hedychium species and their associated bioactivities
