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, 2022-10) Mishra, Dhruv; Chaturvedi, Preeti
    Globally, fertilizers play a significant role in increasing agricultural crop production. owever, non-targeted application and the high cost of the conventional fertilizer is a major bottleneck for soil health and environmental safety. Therefore, there is a need to develop a sustainable approach for synthesis and the utilization of the fertilizer that reduces its costs through an effective and targeted application. The present study aimed to synthesize zinc oxide nanoparticles (ZnO NPs) and urea doped calcium phosphate nanoparticles (CaP-U NPs) as crop nutrients that are distributed in a controlled manner for use as a fertilizer. Both nanoparticles have outstanding biocompatibility and played an essential role in plant growth. The fabricated NPs were characterized by UV-Visible Spectrophotometry, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) Dispersive X-Ray Spectroscopy (EDX), Zeta Potential and Transmission Electron Microscopy (TEM). Under in-vitro condition, ZnO NPs at 100 μg/ml, inhibited 73.5% of DPPH concentration. ZnO NPs, showed strong anti-inflammatory activity and antibacterial activity against S. aureus and E. coli. Application of ZnO and CaP-U NPs on finger millet (Eleusine coracana (L.) Gaertn) (var. VL-379) under in-vitro conditions significantly increased seed germination, seedling vigour, shoot-root length, fresh and dry weight, chlorophyll content, SOD, POD and APX activity. Under glasshouse conditions, foliar spray of ZnO NPs (50 and 100 ppm), ZnSO4 (50 and 100 ppm), CaP-U NPs (0.1 and 0.5 %) and bulk urea (0.1, and 0.5 %) at 15 and 30 days after sowing significantly enhanced shoot-root length, plant fresh and dry weight, Chlorophyll a & b, proline, total phenolic content and antioxidant defense enzymes and significantly lowered MDA and H2O2 content under drought stress. The results of the study revealed that both the NPs play a significant role in augmenting finger millet growth as well as alleviation of the adverse effects of drought.

    “Clonal propagation and bioprospection studies of marchantia spp.”
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Negi, Sweta; Chaturvedi, Preeti
    Bryophytes are first successful land colonising plant community. They form second largest taxonomic category of plants after angiosperms. Although, these are rich in biochemical compounds, yet their chemistry has been negligibly explored much due to habitat specificity and low sample availability. The present study consists of two major experiments. First experiment investigated theprotocol for mass multiplication of one of the most important genera of bryophytes i.e., Marchantia. Lab cultivation of 2 species of Marchantia, M. polymorpha and M.papillata was successfully done through in vitro MS medium culture and ex vitro soil culture respectively. Gemmae (surface sterilized with 1% sodium hypochlorite) were used as an explant for in-vitro culture of M. polymorphaonhalf strength MS mediumw/o sucrose.Among all tested lights, nutrients and temperature conditions, optimum thallus proliferation was seen in white light at 20°C. For ex vitro soil culture of M. papillata, treatment with rice-washed water in soil,sand,cocopeat and vermicompost mixture showed best results for thallus proliferation. Lab established clonal population of M. papillata was bio prospected for various biological activities and results were compared with those of the wild population in the second experiment. Methanolic and aqueous extract was subjected to both enzymatic and non-enzymatic antioxidant assays. Anti-inflammatory activity and anti-diabetic activity was measured by egg-albumin protein denaturation assay and α- amylase inhibitory assay respectively. Methanolic extracts of lab propagated plants exhibited higher antioxidant and anti-diabetic activity whereas methanolic extract of wild population exhibited higher anti-inflammatory activity. The aqueous extract of lab propagated plants showed highest herbicidal activity. The GC-MS analysis of methanolic extracts of wild and labgrown M. papillata majorly showed the presence of methyl esters, phytol, linoleic acid and sesquiterpenoids etc., contributing to the pharmacological effects such as antioxidant, anti-inflammatory, anti-tumor, antidiabetic etc.Comprehensively, this study allows to obtain the monocultured sample availability all around the year resulting in the conservation of species as well as usage of in-vitroand ex vitro grown axenic populationsas a substitute of wild populations of for research and clinical purposes.

    Digitization of G.B. Pant University herbarium
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Sharma, Roopali; Rawat, D.S.
    Herbaria are the main source of information in plant taxonomy and required in research on biodiversity, ecology, and evolution. Till a few decades ago a visit to herbarium was essential to utilize this resource but with the advancement of digital technology herbaria are now accessible on the internet. A small herbarium exists in the Department of Biological Sciences, CBSH, Pantnagar but it is not accessible on the internet. The goal of the current study was to digitize this herbarium with limited resources available and to make it accessible through the internet. All the herbarium specimens were family wise arranged following APG IV classification and within family genera and species were arranged in alphabetical order. Information on specimen labels was digitized and a complete catalogue of specimens was prepared. Each species name was checked in Plants of the World Online database for its current systematic position and accepted name. Images of specimens were prepared using a DSLR camera. A website tentatively named as ‘Virtual Herbarium Pantnagar’ was created on Google site tool with 07 main pages and 89 subpages. Resized images of one specimen for each species were uploaded on the subpages dedicated to each seed plant family. Few more images of the same species are also accessible through embedded hyperlinks. Currently accepted name, accession number, collector’s name and links to more specimens were also provided with each image. There are a total 1,342 herbarium sheets stored in the physical herbarium which represent 34 orders, 84 families, 301 genera, 416 species of angiosperms, 01 order, 02 families, 03 genera, 03 species of gymnosperms and 35 voucher specimens. In virtual herbarium 454 images of herbarium specimens are displayed while 365 images are accessible by hyperlinks. Voucher specimen images (35) are displayed on two separate pages under ‘Voucher specimens’. Caryophyllales (204 specimens, 07 families, 34 genera, 64 species), Lamiales (159 specimens, 11 families, 37 genera, 49 species), Poales (92 specimens, 02 families, 36 genera, 48 species) are three largest orders and Asteraceae (123 specimens, 23 genera, 23 species), Fabaceae (118 specimens, 34 genera, 51 species), Caryophyllaceae (110 specimens, 18 genera, 43 species) are three largest represented families in the herbarium. The ‘Virtual Herbarium Pantnagar’ after publication on the internet will make the herbarium accessible globally and it may serve as a template for very small herbaria to display their wealth of herbarium specimens to all interested researchers in the world arena by developing similar databases.

    Impact of natural farming inputs and their microbes on the growth of french bean (phaseolus vulgaris l.) and onion (allium cepa L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Pandey, Janarjan; Sharma, A.K.
    Use of Natural Farming Inputs is viewed as one of the means to avoid using synthetic and inorganic chemicals in agriculture while also achieving the organic goals and sustainability. Present study was planned to check the impact of natural farming inputs and their microbes in the growth of French bean (Phaseolus vulgaris L.) and onion (Allium cepa L.). A field experiment was conducted to see the effect of different natural farming inputs on growth and yield of onion and French bean. The treatments used were T1- Control, T2- Vermiwash, T3- Beejamruth + Jeevamruth, T4- Amritpani + Jeevamruth, T5- Beejamruth + Vermiwash, T6- Beejamruth + Panchgavya + Amritpani, T7- Beejamruth + Jeevamruth + Panchgavya, T8- Beejamruth + Jeevamruth + Vermiwash, T9- Vermiwash + Panchgavya + Amritpani, T10- Panchgavya. Out of which T3 showed higher plant fresh weight, weight of bulb per plant and importantly higher yield as compared to other treatments and control in onion. Whereas in French bean, T9 showed the higher root length, plant fresh weight, number of pod/plant, length of pod, weight of per pod, diameter of per pod, total yield, and foliar nutrients like total nitrogen, total potassium; total sugar and total protein as compared to other treatments. The microbial activity of natural farming inputs was analyzed, in which the higher number of bacterial, fungal, zinc and potassium solubilizing bacterial population was found in Panchgavya. Higher actinomycetes, nitrogen and phosphorus solubilizing population were present in Jeevamruth. In glasshouse, an experiment was conducted to study the role of microbes present in natural farming inputs in French bean. The treatments used were Panchgavya, Jeevamruth, Amritpani, Beejamruth, Vermiwash and the microbes isolated from each. Panchgavya showed the higher root length, fresh weight, dry weight, length and weight of pod, organic carbon, foliar nitrogen content, foliar phosphorus content, urease activity, acid phosphomonoesterase activity and alkaline Phosphomonoesterase activity as compared to control and other treatments. Compared to all isolated microbes, better results were shown by microbes isolated from Panchgavya. Present study showed that natural farming inputs can be used as effective natural method to enhance the crop growth and productivity under natural conditions and can be a good replacement for chemical fertilizers.

    Distribution of angiosperms in the Himalaya
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-09) Dhoundiyal, Anurag; Rawat, D.S.
    Angiosperms are a highly diverse and most successful plant group on Earth. The Himalaya is a mountain chain which is exceptionally rich in harbouring diverse angiosperm flora and recognized as one of the 36 biodiversity hotspots of the world. An exclusive Flora of the Himalaya does not exist and angiosperm diversity in the entire mountain range is speculative. Considering this lacuna an attempt is made to assess angiosperm diversity and its distribution in the Himalaya. Data in this work has been collected from various floristic accounts such as books, Floras, monographs, and research papers that represented the flora of one or the other regions of the Himalaya. Every species is enumerated in the checklists of families after following APG IV system of classification and cross-examining them in Plants of the World Online and Catalogue of Life 2022 databases for currently accepted names. The results show presence of 11,624 species, 2,369 genera and 228 families belonging to 52 orders in the Himalaya. These numbers are higher than the earlier estimates and prove that 3.44% of the angiosperm species known in the world can be seen in the Himalaya which constitutes only 0.262% of the land surface of earth. Similarly, 17.29% genera, 54.80% families and 81.25% orders of the angiosperms known in the world are represented in the Himalaya. Order Poales Small (1,328 species), Family Poaceae Barnhart 864 species) and genus Carex L. (186 species) emerged as the largest taxa. Out of all subdivisions, Nepal was having highest number of species (5,719) followed by Bhutan (5,717), Sikkim (5,476), Arunachal Pradesh (4,752), Uttarakhand (4,589), Jammu Kashmir (3,305), Himachal Pradesh (3,146) and Darjeeling (1,694), respectively. The distribution patterns of 30 dominant families and genera show that 13 families and 10 genera show a clear trend of increasing number of species from western to eastern Himalaya and 4 families and 7 genera show the opposite trend. Other 13 larger families and 13 genera do not show any conclusive trend. The results demonstrate that the Eastern Himalayan region is richer in taxa and contributes to a larger fraction of species richness in the Himalaya in comparison to Western Himalayan region.

    Evaluation of phytochemicals and antioxidant potential of six selected tree species
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2022-03) Chanyal, Vimal Kumar; Rao, P.B.
    Traditional systems of medicine, modern medications, nutraceuticals, food supplements, folk medicines and pharmaceutical intermediates etc., used medicinal plants as a source of innovative drugs. In the present study, antioxidants activity of six tree species in both aquamthanol and aqua acetone extracts was assessed by using standard methods. Highest yield in aqua-methanol and aqua-acetone extracts was obtained both in Putranjiva roxburghii (21.09 % and 18.60 %, respectively). Majority of the phytochemicals were present in all the selected plant species. In aqua-methanol extract, oils and resins were absent in A. marmelos, C. fistula, and P. roxburghii; saponins were absent in M. philippensis, A. marmelos and A. indica. In aqua-acetone extract, quinones were absent in Aegle marmelos and Syzygium cumini; terpenoids were absent in Azadirachta indica; and saponins were absent in Mallotus philippensis. DPPH scavenging activity (%) was maximum P. roxburghii (68.16 ± 0.38 and 66.73 ± 0.52) in both aqua-methanol and aqua acetone extracts, respectively. Comparatively lower IC50 (μg/ml) values of DPPH were obtained in M. philippensis (26.82 and 81.49) in both aqua-methanol and aqua-acetone extracts, respectively. Comparatively higher FRAP activity (μg GAE/mg of extract) was exhibited by A. indica (31.06 ± 0.35) and M. philippensis (17.53 ± 0.30) in both aqua-methanol and aqua-acetone extracts than in rest of the tree species. The TPC (μg GAE/mg extract) was highest in M. philippensis (31.21 ± 0.18 and 28.37 ± 0.16) both in aqua-methanol and aqua-acetone extracts, respectively, while TFC (μg QE/mg extract) was in M. philippensis (29.66 ± 0.41 and 26.69 ± 0.30) in both aqua-methanol and aqua-acetone, respectively. Positively strong correlation was exhibited in terms of DPPH, FRAP, and TPC by most of the plant species in both the solvents except in M. philippensis, in which, it was very weak between TPC vs FRAP. Thus, among the solvents, aqua-methanol extracts exhibited comparatively higher antioxidant potential than aquaacetone and among the species, P. roxburghii and M. philippensis showed comparatively higher activity than in rest of tree species. Therefore, these tree species can be used as a natural plant antioxidant and can be exploited in pharmaceutical and nutraceutical industries.
