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.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2005-06) Bhatt, Pankaj; Melkania, Uma
    The forest is a fundamental natural resource that represents value for many aspects of human development. Forests provide a lot of goods and environmental services, which must be properlyaccounted to evaluate the total dconomic value of the forest. Theree has been a growing recognition of the intangible benefits desived ftom the forest, like the role of forest in meetigating the effect of green house gases by carbon sequestration. During the course of this study, carbon sequestration, one of the major intangible benefits is valued by using replacement cost method. The value of the carbon stored in forest is evaluated by the cost that would be in curd in offsetting by alternatives means the CO2 realised by forest plant conversion. The present study was undertaken in the Oak forest of Nainital, to assesss the prelocked stocek of carbon in two oak forest of varying degree of distrubencee. The present status pf the forest was studied by standard ecological methods. The biomass stored was determine byt using the allometric equations. Results showed that in case of stock forest , the contribution of querces to the total forest biomasss was 84% ehich decreased to 62% in disturbed forest site> The carbon content was determinewd by Ash method and by regrewsssion methods. The bioles stem had the maximum carbon percentage followed by twigs and leaves. Acconting for the above grown carbon stocks only in the forest yield and annual flow of U$ 1179621 – IS $ 93544.7. This reflects the immense economic and ecological value of the forest.

    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.

    Removal of textile dyes from aqueous solution using low cost adsorbents
    (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.

    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.

    Energy flow in a mountain agro-ecosystem during summer cropping in Kumaun Himalaya
    (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.
