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.

    IN-VITRO STUDIES ON NANOPARTICLE MEDIATED BIODEGRADATION OF ELECTRONIC WASTE BY NATIVE BACTERIA
    (2023-02-01) Chakraborty, Moumita; Rai, J. P. N.
    The management of electronic waste (e-waste) becomes a global issue in this digital era. Plastics are neither the main residue nor the most important pollutant in electronic trash, but they take up a lot of room due to their low density and the forms of their parts. They make up about 17 percent of the WEEE (Waste from Electrical and Electronic Equipment) stream. More than 55% of all the polymers in e-waste are made up of ABS (Acrylonitrile Butadiene Styrene) and HIPS (High Impact Polystyrene Sheet). Existing conventional practices are harmful for dealing with e-waste, therefore, indigenous soil bacteria were explored for e-waste treatment through enrichment culture approach followed by screening, identification and their characterization used for in-vitro biodegradation investigation. Soil bacteria were enriched in the presence of e-waste for 6 months and the findings were established through optical density value that were higher in the case of soil enrichment than the control. Based on their morphological, biochemical and molecular characterizations, the bacterial isolates MGP1, MGP4 and MGP15 were identified as Bacillus aryabhattai, Sporosarcina sp., Rhodococcus kroppenstedtii. The selection and biocompatibility testing of potential isolates were performed for the formation of bacterial consortia. All the isolates displayed their best performance at pH 7, temperature 30°C and shaking speed 120 rpm. Supplementing the nutrient medium with additional carbon and nitrogen sources enhanced the rate of polymer degradation by the bacterial isolates. A known bacterial strain Pseudomonas fluorescens was selected for the degradation of the electronic waste and its comparison with that of screened bacterial isolates. Comparative studies showed that e-waste degradation potential of consortium is better than the individual bacterial strains. Titanium Dioxide (TiO2) nanoparticles were used to study its effect on biodegradation ability of the best suited bacterial strain. The biodegradation of e-waste by the selected strains during in vitro experiment was confirmed by analytical processes like FT-IR, FESEM, EDX elemental analysis. Thus, this study besides providing direct and standardized protocol for screening and selection of efficient e-waste utilizing bacteria is also demonstrating potential consortia which are ready to be used. The bacterial isolates were able to degrade e-polymer both in media and soil and therefore can be used profitably for field scale bioremediation technology.

    Assessment and characterization of microplastics in Gaula river
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-08) Sheikh Shifa; Saraswat, Shweta
    Plastic pollution is presently a serious environmental threat and microplastics are plastic fragments that are less than 5 mm in size which created bigger environmental threat because of their small size. This research work highlighted the assessment and characterization of microplastics in Gaula River. A few methods suitable for sampling them are sieving, filtration, visual sorting, digesting, and density separation. The FTIR characterized different type of microplastics in both the upstream and downstream samples such as polyethene (PE), Poly vinyl chloride (PVC), polypropylene(PP), polystyrene(PS), high density polyethylene (HDPE), low density polyethylene (LDPE), Polytetrafluoroethylene (PTFE), and polyamide (PA). According to SEM images, majority of microplastics in both upstream and downstream were fibers followed by fragments, films and pellets and the size of the microplastics were found to be in the range of 30-100 μm (0.03-0.1 mm). Fiber was the dominant shape. EDS for microplastics in upstream and downstream represented additional peaks for carbon and oxygen along with the peaks of other elements. The elements C is significant component of polymers and the occurrence of its peaks confirms the presence of microplastic. While SEM-EDS and FTIR were the identifying techniques applied in this research work, there is still a need and space for the development of more practical and accessible methods. The assessment and characterization of microplastics was done in Gaula River and the presence of microplastics was confirmed in both upstream and downstream sites and the number of microplastic particles was found to be higher in downstream site than upstream site.

    Defluoridation of groundwater using low-cost biosorbents
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-07) Tewari, Pratibha; Saraswat, Shweta
    The present study was carried out to reduce the fluoride contamination in groundwater using low-cost biosorbents viz. egg-shell powder (ES Powder), rice husk dust (RHD) and coconut Fibre Dust (CFD). The biosorbents were characterised using Fourier Transform Infrared (FTIR) analysis and their functional group peaks were identified. The optimization of different biosorbents was performed at various parameters such as pH, initial fluoride concentration, adsorbent dose, contact time,agitation speed and temperature. Fluoride adsorption efficiency was also compared using SPADNS method of fluoride testing and absorbance was taken using UV-visible spectrophotometer before and after adsorption. Among all biosorbents, maximum fluoride adsorption was obtained using egg shell powder at pH 6, 600 rpm, at 5 g/100ml of adsorbent dose and 1.5 mg/L initial fluoride concentration at 30°C temperature. The maximum fluoride removal efficiency of egg shell came out to be 88%. The biosorbents were reused four times and RHD showed maximum regeneration power of 56% in fourth stage. The results revealed that the low-cost biosorbents are promising resource for the defluoridation of groundwater which may ensure the availability of safe drinking water among the poorer sections of the society in fluoride contaminated areas.

    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-07) Ratha, Sonali; Rai, J. P. N.
    The present study was carried out in order to use various natural coagulants to reduce turbidity of potable water. The coagulants used were rice husk, Moringa oleifera seeds, groundnut shell and sago seeds. They were used in doses of 1g, 2g, 3g, 4g, and 5g and the research work was carried out in pH range of 6.5-8.5. Synthetic turbid water of 100 NTU was prepared and used for carrying out the experiments. Maximum turbidity removal efficiency was of sago seeds with an efficiency of 99.56 when pH was 7. Fourier Transform Infrared (FTIR) analysis of the natural coagulants were done to determine the functional groups present in the coagulants which aid in coagulation process. It was observed that silica derivatives in rice husk, proteins and lipids in Moringa oleifera and groundnut shell and starch present in sago seeds were aiding in coagulation process. It was observed that natural coagulants showed good turbidity removal efficiency and the sludge obtained after their use was also very minimal.

    Groundwater quality of Lalkuan and its suburb and the disease incidences after its consumption
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Arya, Divya; Rai, J. P. N.
    Groundwater resources are important sources of drinking water in India, and they are hugely important in satisfying the urban water needs and supporting a varied range of commercial and agricultural activities. The modern civilization, industrialization, urbanization and increase in population have lead to fast degradation of our groundwater quality. Groundwater contains various types of pollutants and several other substances are dissolved in it. Concentration of which is useful for the human body but in a specific limit. The present study was undertaken to analyze the Groundwater quality of Lalkuan and its suburb and the disease incidences after its consumption. Different parameters (pH, EC, TDS, Ca, Mg, Cl, SO4, PO4, NO3, TH, F, BOD, Fe, Zn, Pb, Cd, and Cu) were analysed so as to determine the physicochemical parameters of groundwater. To determine the prevalence of diseases caused by poor water quality, a survey was carried out in the Lalkuan area. The common illnesses and the variables affecting water quality were correlated. The results showed that groundwater quality of Lalkuan and its suburbs was average. Site 1 was the most polluted site among all the sites. It was found that diarrhea and typhoid were the most prevalent illnesses. pH, fluorides, lead, copper and cadmium were negatively correlated with diarrhea and turbidity, TDS, TA, total hardness, calcium, magnesium, chlorides, phosphate, nitrate, BOD, zinc and iron were positively correlated with diarrhea. Correlation analysis showed that the water quality leads to disease like diarrhea.
