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.

    Suitability of non-conventional adsorbents for the discolouration of textile dyes from their aqueous solutions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Kalla, Bhavna; Gupta, R.K.
    Effect of various non-conventional adsorbents (bagasse, rice husk and wood ash) were studied on different concentrations of three dye solutions for the changes in colour and pH, at varying time periods (1, 2, 3, 4 and 5 hours). Discolouration of dye solutions increased with increasing dye concentration upto 40ppm, by treatment with various adsorbents. The discolouration also increased with the increase of time up to 4 hours. However, the rate of colour removal was highest in first hour of treatment. Effects of different amounts (0.25, 0.5 and 1.0 gm/50 ml dye solution) of various adsorbents on changes in colour and pH of three dye solutions were investigated. Discolouration considerably increased when adsorbents were employed up to the amount of 0.5 g; afterwards colour removal was negligible. Effects of adsorbents (bagasse, rice husk and wood ash) singly and in combinations on pH, colour and COD of the dye solutions were studied. In all 3 dyes, there was an increase in pH when adsorbents singly and combination were employed, the increase was maximum in Malachite green. The colour reduction was slightly higher in combinations than adsorbents when employed singly. Effect of adsorbents (bagasse, rice husk and wood ash) singly and in combinations led to maximum COD reduction in Crystal violet solutions and minimum in Congo red solutions.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2004-01) Tanushree; Gupta, R.K.
    Effect of various adsorbents - pressmud, corncob and tea leaves on changes in colour and pH of different concentrations of three dyes at varying time interval (1, 2, 3, 4 and 5 hours) were studied. Decolourization of dye solutions increased with increasing dye concentration upto 30ppm by treatment with various adsorbents. The decolourization also increased with the increase of time up to 5 hours. However, the rate of decolourization was highest after one hour of treatment. Effects of different amounts (0.25, 0.5 and 1.0 gm/50 ml dye solution) of various adsorbents on changes in colour of three dye solutions were investigated. Decolourization was considerably increased when adsorbents were employed up to the amount of 0.5 gm; afterwards colour removal was negligible. Effects of adsorbents (pressmud, corncob and tea leaves) when employed singly and in combination, on pH, colour and COD of the dye solutions were studied. The treatment of all the dye solutions with various adsorbents, singly and in combination yield nearly the same reduction in colour and COD.

    Feasibility assessment of biological hydrogen production from organic fraction of municipal solid waste using facultative anaerobic bacteria
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-09) Sharma, Preeti; Melkania, Uma
    The rapid consumption of non-renewable fossil fuels has resulted in the environmental pollution and severe energy crisis, which emphasize the importance of renewable biofuel production. Biological hydrogen is a carbon-free renewable energy carrier, with high energy density. Biological hydrogen production methods are less energy intensive, environmental-friendly and sustainable compared to the current energy production methods. Anaerobic digestion is an effective means of organic waste utilization and hydrogen production. At the same time, waste disposal is a problem of the modern times. Most of this waste is dumped in open areas creating severe environmental problems. The organic fraction of municipal solid waste (OFMSW) is highly degradable, thus anaerobic fermentation of OFMSW can be one of the promising methods to generate hydrogen as it is abundant and free of cost. It provides an eco-friendly solution to organic waste by converting waste to biofuel. The present study investigates the feasibility assessment of biological hydrogen production from organic fraction of municipal solid waste. Co-culture of two facultative anaerobic bacteria viz. E. coli and Enterobacter aerogenes were applied for the investigation. Culture conditions were optimized to gain maximum hydrogen production. Various chemical compounds such as surfactants, antifoaming agents, biochar, ferric species etc were applied to improve hydrogen production. Some inhibitors such as furan derivatives, phenolic compounds and heavy metals were also analyzed for their effect on hydrogen production and yield. From the present investigation it can be concluded that proper optimization of fermentation conditions can significantly improve hydrogen production and yield. Based on the findings of the present study it is recommended to further investigate the effect of different substrates and microbial cultures on hydrogen production in order to increase the hydrogen yield.

    A study of fixed-bed biofilm sequencing batch reactor for pollutant removal from agro-based industrial effluent
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-06) Singh, Mohini; Srivastava, R.K.
    Water is one of the most vital components of the earth. It is not only essential for survival of animals and plants but also occupies a unique position in industrial development of nation. The agro-based industries consume considerable quantities of water during their processes and generate large volumes of effluents which ultimately pollute the environment. In present study, the raw and primary treated starch industry effluent from Riddhi Siddhi Gluco Biols (RSGB) Ltd., Pantnagar had been selected for pollutant load study and its mitigation by development of an appropriate technology. Sequential Batch Reactor (SBR) technology is basically a fill-and-draw activated sludge process. Fixed-bed Biofilm Sequencing Batch Reactors (FbSBR) used in present study is the modified version of SBR in which fixed media is used as support for biofilm formation under aerobic conditions with altering anoxic conditions. During the start-up operation, three 18 L bioreactors were operated in batch mode for 28 days with synthetic water solution for biofilm formation and substrate stabilization. After stabilization period of 28 days, these bioreactors were operated in continuous mode with 24 hr cycle/day. The type-A and B FbSBR were fed with raw and primary treated effluent respectively while control i.e. type-C with primary treated effluent. Experiments were conducted in four periods each having different anoxicaerobic hydraulic residence times (􀈙H anoxic = 3-12 hr and 􀈙H aerobic = 6-15 hr) in order to determine the optimum HRT for highest pollutant removal. The total reaction time was kept constant at 18 hr for all operational periods. It was found that type-B FbSBR at HRT of 􀈙H anoxic = 6 hr and 􀈙H aerobic = 12 hr gave better removal efficiency for COD, BOD, TKN, total solids, total suspended solids, total dissolved solids, chloride and sulphate in comparison to the type-A and control. The experimental results indicated that anoxic and aerobic residence times in FbSBR significantly affected the system’s performance. Thus, in present study it was observed that FbSBR reduced the pollutants concentration, particularly organics and nitrogen more as compared to conventional sequential batch reactors (SBR). Therefore this technology can be considered as efficient and cost effective for the treatment of agro-based industrial effluent.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2008-06) Singh, Kundan; Singh, Vir
    Energy flow through a mountain agro-ecosystem was analysed in a cluster of five mid-altitude villages in the Pithoragarh district of the Kumaun Himalaya during summer (Kharif) cropping in 2007. Information was derived from 50 families (10 families in each village), resource persons and secondary sources. There were, on an average, 87 households per village. The average family size of the villages was 6.22. Average population per village was 476. An average land holding size was one ha. Upland rice and finger millet-pulses covered the largest area. On an average, there were 64 bullocks, 46 cows, 98 buffaloes, and 144 goats per village. Maximum amount of energy (274.50x105 kJha-1) was invested through manure (53.55 percent of the total energy), followed by chemical fertilizers (97.09 x105 kJha-1) and pesticides (82.88 x105 kJha-1), and minimum through seeds (15.15x105 kJha-1). In the form of useful outputs (grain and straw), a gross energy value of 10260.95 x105kJha-1 was harvested during summer cropping. The largest amount of energy was produced through fruit production (3246.60x105kJha-1), which was about 32 percent of the gross energy produced in one ha cropland during summer season. Gross energy output - input ratio of the tree-based fruit crops was the highest (61.291) of all the crops. Root and tuber crops showed comparatively higher energetic efficiency (17.833) than other vegetables (9.471). Amongst the food grain crops the maximum energetic efficiency (37.782) was recorded in amaranth-kidney bean cultivation followed by finger millet-pulses (23.884) and the minimum in soybean cultivation (3.438) The livestock population (converted into cattle units) consumed 144638094.9 kJ per day or 52792904649 kJ in a year and, in turn, produced 8490715137.07 kJ in a year through dung, 2056277724 kJ though milk, 60704289.30kJ through calf crop and 6416.35 kJ by means of draught power supply to crop fields. The gross energy produced by livestock was 10607703567kJ per year. The largest proportion of the output energy was received through dung (80 percent), followed by milk (19 percent). Contribution of calf crop and of draught animal power (DAP) was minimal compared to the overall energy. The gross energetic efficiency of livestock production was 20.09 percent. Energy for maintenance and growth available for livestock was 25.15 percent. A substantial proportion of energy in a mountain agro-ecosystem, thus, flows through livestock component. The energy flow considerations in an agro-ecosystem are of phenomenal socio-economic importance for realizing food security, social progress and sustainable development which are rooted into an agro-ecosystem and are influenced by ecosystem functioning, which in turn, is influenced by the skills and level of resource management.

    Use of biowaste for electrical energy production through microbial fuel cells
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Rashmi; Srivastava, R.K.
    Waste is a common term for all kind of unwanted materials generated during the extraction and processing of raw materials to get intermediate and final products. There are different sources of biowaste generation, which includes agriculture, industrial, domestic waste, municipal solid waste, commercial and institutional etc. Municipal solid waste is mainly generated from domestic kitchen waste and commercial complexes. With the increase of urbanization and change in socio-economic system, lifestyle and food habits, the amount of municipal solid waste has been increasing rapidly over years and its composition is getting changed. Poor collection and incomplete transportation are responsible for the accumulation of MSW at every nook and corner. In India, about 10% of the collected MSW is openly burnt and is caught in landfill fire. Such open burning of MSW and landfill fires together releases 22,000 tons of pollutants into the lower atmosphere. A major portion of the total solid waste in developing countries is an organic waste, and it is not properly treated for resource recovery. Organic waste treatment is also a top priority in the developing countries. Microbial fuel cells (MFCs) are an alternative energy technology that has the capacity to simultaneously treat organic waste and generate electricity. The aim of present study was to manage the solid waste and generation of electricity by using microbial fuel cell (MFC).MFCs is used to generate electricity while accomplishing the biodegradation of organic matters by microbes. The objective of present work was generation of electricity by mixture of different biowaste as a substrate in MFC. The experimental study was carried out by using biowaste (Kitchen waste, cow dung and poultry waste), zinc and copper plates of dimension length=15 cm and width 4.5 cm with potassium ferricyanide used as an oxidizing agents. In all the setup maximum electricity generation was measured between 321 to 736.66 mV by using mixture of kitchen waste with cow dung waste and poultry waste. In all setup maximum electricity generation of 736.66 mV was recorded by using only 100% poultry waste. Overall, this study has shown that the fabricated microbial fuel cell can be used for the generation of electricity from different kinds of biowaste at a larger scale in series with continuous feeding of biowaste and it can be considered as eco-friendly system for solid waste management.

    Estimation of carbon stock using remote sensing and GIS: A case study of Rajaji National Park
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Rawat, Sampda; Melkania, Uma
    The present study was carried out at three different sanctuaries namely Motichur, Rajaji and Chilla sanctuary that comes under the Rajaji National park, Uttarakhand, India during 2016-17.The sampling in the forest region was carried out within the plots (size 10 x 10 m) in a random fashion. The sampling was done for determining the soil parameters like soil organic carbon and to design a plant inventory comprising of plant height, DBH, wood density and plant density in the plot. The forest of the study area were natural forest but had some patches of plantation forest also. In the naturally growing forest Sal was the dominant tree species whereas in the planted region Eucalyptus and teak trees were more common. The plant density was generally high; the diameter and height of the plant varied in accordance with the age and species of the plant. The carbon content of the soil pool was ranging between medium to high level of carbon. Remote sensing and GIS technology tools were used for forest carbon stock determination. The software like ENVI 4.7 was utilized in the preprocessing of the satellite image, whereas, ArcGIS was use to prepare shape file of the study region. The vegetation carbon pool was 50% of biomass estimated for the forest. Total vegetation carbon was 0.7915 mt, 2.0046 mt and 1.2692 mt in Motichur, Rajaji and Chilla sanctuary respectively. Motichur, Rajaji and Chilla forests were having soil organic carbon 0.5029, 1.354 and 0.9969 mt respectively. Total (aboveground, belowground and soil) carbon pool of Rajaji National park was about 6.9191. These results reveal that relatively an evergreen forest (Chilla sanctuary) sequester more carbon into vegetation biomass as well as soil organic carbon.

    Lead phytoextraction efficiency of Sesbania aculeata and Pennisetum purpureum in soil, inoculated with tolerant bacteria
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-07) Gururani, Akansha; Rai, J.P.N
    The study was conducted to assess the effect of plant growth promoting bacteria (PGPB) inoculation on lead phytoremediation. Metal tolerant bacteria were isolated from a lead contaminated site and the isolated strains were screened for plant growth promoting properties. Based on it a metal tolerant and growth promoting bacterium was selected. Its potential was further checked with pot experiments for two plants; Sesbania aculeata and Pennisetum purpureum at 100 ppm and 200 ppm concentration of lead. The efficiency of phytoextraction was indicated by the increased accumulation of lead in shoot and root of inoculated plants. Also, increase in growth parameters and activation of stress relievers like proline and catalase suggested the effectiveness of the assistance provided by PGPB. Other physiological parameters like total chlorophyll content and protein content values were also affirmative of the enhancement of phytoremediation on bacteria inoculation. The reported data imply that PGPB imparts tolerance against metal toxicity to plants. Out of the two plants, Sesbania aculeata showed better results than Pennisetum purpureum with or without inoculation in terms of lead accumulation, growth enhancement and metabolic functioning. However, the effect of PGPB was similar in both the plant species over absolute control and over control supplemented with lead. Therefore, it can be deduced from our study that inoculating a metal tolerant-plant growth promoting bacteria can enhance the efficiency of phytoremediation.
