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.

    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.

    Equilibrium modeling and kinetic studies on the biosorption of Chromium (III) from synthetic waste water using Cupressus torulosa and Taxus baccata”
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Verma, Anil; Viveka Nand
    In recent times, Heavy metals in general and chromium in particular has received a great deal of attention because of their toxicity. Studies were undertaken to examine the biosorptive ability of Gymnosperm plant species, Cupressus torulosa, and baccata, , collected from high altitude of Uttrakhand hills, to remove the Chromium (III) metal ions from aqueous solution. Batch mode experiments were conducted at cold and hot temperatures (25˚±5˚C and 40˚±5˚C) to study the effects of initial Cr (III) metal ion concentrations, pH, time and amount of biomass. Thus a removal of chromium is essential from the environment by cheap and ecofriendly process. The maximum percentage removal (%removal) and biosorption capacity (Qe value) were recorded at equilibrium conditions. The maximum removal of Cr (III), at cold and hot temperature condition by by C. torulosa and T. baccata, leaves were 97.83 and 93.66, 97.83 and 93.66 while by barks were 90.53 and 93.66% , 90.33 and 93.23% respectively. Langmuir, Freundlich and Temkin adsorption isotherm models were used to explain adsorption phenomenon of Cr (III) removal. Equilibrium data agreed well for biosorption of Cr (III). The kinetic data have been analyzed using Pseudo first order, Pseudo-second order and Elovich kinetic models. The experimental data fitted very well the Pseudo second order and Elovich kinetic models. The FT-IR spectra of dried unloaded and Cr-loaded plants biomass were obtained to understand the nature of possible interactions between the chromium metal ions and the functional groups of biosorbents. The FT-IR analysis revealed that the main functional groups involved in biosorption were carboxyl, carbonyl, amino, alcoholic and phenol. Significant morphological changes were observed using SEM analysis, which support the binding of metal with leaves and bark surfaces. Thus, it can be concluded that gymnosperms can be utilized as cost-effective and environment friendly alternative over commercial methods of treatment for removal of toxic metals and contaminants of water because these plants consists high metal binding properties at different environmental conditions.
