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.

    Synthesis, characterization and drought stress alleviating attributes of zinc oxide and urea doped calcium phosphate nanoparticles on Eleusine coracana (l.) gaertn.
    (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.

    Efficacy of multitrait plant growth promoting bacteria on growth promotion of rice and wheat under water stress and irrigated condition
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-03) Bind, Sudha; Sharma, A.K.
    Plant growth promoting bacteria (Endophytic and rhizospheric bacteria) have been reported to play key role in alleviation of water stress through various mechanism. In present study, 16 previously isolated endophytic bacteria form rice variety Sahbhagi were characterized by biochemical and functional basis and further evaluated for their efficiency of growth promotion of wheat variety PBW343 under water stress and irrigated conditions. Four endophytic bacteria were selected on the basis of functional characteristics and plant growth promoting ability of wheat and further tested for their growth promotion efficiency of rice variety Sahbhagi under water stress and irrigated condition. Selected endophytic bacteria were compared with rhizospheric bacteria, Variovorax paradoxus (RAA3) and Pseudomonas palleroniana (DPB16) for their efficacy of growth promotion on rice variety IR64 under water stress and irrigated condition. Result showed that endophytic bacteria (Seed 16), was more efficient in plant growth promotion under both water stress and irrigated condition than rhizospheric bacteria. Endophytic bacteria (Seed 16) inoculated along with Arbuscular mycorrhizal fungi (AMF) on rice and wheat under water stress and irrigated condition, result showed that interaction of endophytic bacteria with AMF was more efficient in alleviation of water stress and significantly enhanced rice and wheat growth, than the single inoculation with each organism. Seed 16 was identified as Enterobacter roogenkampii strain S16 using 16S rDNA sequence analysis. Two rhizospheric bacteria Variovorax paradoxus (RAA3) and Pseudomonas palleroniana (DPB16) were evaluated for their effect on growth and yield of two rice variety (DRR44, IR64) and two wheat variety (WH1105, PBW343) under rainfed and irrigated condition in field study. RAA3 significantly enhanced the all yield contributing parameters (plant height, total no of plants, no of tillers, panicle /spike length, no of grains/ panicle or spike, weight of 1000 grains), chlorophyll and enzymatic antioxidants, nutrient content in both rice and wheat under rainfed and irrigated condition. In field experiment of rice, RAA3 treated plants showed maximum grain yield (4.86 ton/ha, 5.13ton/ha) under rainfed and irrigated condition respectively as compared to control plant. In case of wheat, RAA3 treated plants exhibited higher grain yield (4.4 ton/ha, 5.06ton/ha) under rainfed and irrigated condition, respectively, as compared to their respective untreated plants. Finding of present study suggested that multi-trait plant growth promoting bacteria and co-inoculation of PGPB along with AMF could be used as effective inoculants to improve the plant growth and productivity under water deficit condition to achieve sustainable agriculture.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-01) Rawat, Deepti; Rao, P.B.
    Sixteen different plant species of family Asteraceae were selected for evaluation of their phytochemical profile in two different solvents. The extraction yield (%) was maximum in Ageratum houstonianum (56.94±0.13 and 66.14±0.20) in both aqua acetone and aqua methanol, respectively. Among the plant species extracts, comparatively higher DPPH activity (%) was obtained in Lagascea mollis (78.93 and 86.84, respectively in aqua acetone and aqua methanol); FRAP (μg TE/mg) in Ageratum houstonianum (166.18±0.13) and Vernonia cinerea (177.86±2.40); and TAA (μg VCE/mg) values in Emilia sonchifolia (90.28±1.36) and Erigeron bonariensis (164.33±0.57) in aqua acetone and aqua methanol, respectively. The values of TPC (μg GAE/mg) were higher in Galinsoga parviflora (67.67±0.37) and Erigeron bonariensis (87.09±0.48); and TFC in Ixeris polycephala (19.76±0.08 and 11.70±0.7 in aqua acetone and aqua methanol, respectively). SOD (DU/mg FW), POD (nmole/mg protein), and CAT (μmole/mg protein) activity were higher in Erigeron bonariensis (20.01±0.02), Cirsium arvense (109.35±0.69), and Xanthium strumarium (45.52±0.13), respectively. The Anti-inflammatory activity (%) was higher in Gnephalium pensylvanicum (89.67±0.45) and Ageratum houstonianum (98.38±0.34) in aqua acetone and aqua methanol extracts, respectively. The anti-bacterial activity (%) was maximum in Blumea sinuata (75.00), followed by in Y. japonica (68.75). Out of total compounds identified by GC-MS analysis in six plant species, the major important bioactive compounds are: guanosine (neuroprotective potential), arbutin (astringent and disinfectant properties), n-hexadecanoic acid (hemolytic, pesticide, lubricant activities), and lupeol (anticancer and anti-inflammatory activities) in Blumea sinuata; beta.-amyrin (anti-fungal and anti-inflammatory activity), betulin (Anti-HIV activity) in C. arvense; and Phytol (hypocholesterolemic, antimicrobial, anticancer, and anti-inflammatory) in all the species. Thus, among 16 different plant species, Lagascea mollis, Erigeron bonariensis, Ageratum houstonianum, Blumea sinuata, Cirsium arvense and Ixeris polycephala are more promising for scientific foundation to exploit potential natural plant resources in terms of antioxidants, anti-inflammatory and anti-bacterial.

    Agro-industrial waste utilization for the production of bioethanol, bioinoculant and compost
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-02) Bind, Sandhya; Sharma, A.K.
    Utilization of agro-industrial wastes for the production of valuable commodities such as bioethanol, bioinoculant and composts provide a solution for global problems such as energy crisis, food security and environmental pollution. In present study, possibility of using waste carrot and pea peel for bioethanol production has been studied and bioethal yield was compared to sugarcane juice. High ethanol tolerance (up to 15%), high glucose tolerance (up to 300g/L) and high ethanogenic (14%) yeast strain Wickerhamomyces anomalus GBY was isolated from ‘Hamei’ sample. Carrot, pea peel juice, sugarcane juice with or without concentration were fermented without addition of nutrients and provided maximum ethanol yield of 15.65 g/L, 21.00 g/L, 90.25 g/L and 80.25 g/L of ethanol, respectively. Pea (PPB) and carrot peel bagasse (CPB) were used as substrate for production of T. harzianum via solid state fermentation. After optimizing growth parameters, maximum spore 3.28×1010 were produced on PPB and 1.17 ×107 spores in case of CPB. Shelf life assessment of talc based formulation of T. harzianum grown on PPB showed that after 90 days of incubation, 60.1% population declined at 4 ºC storage temperature whereas, at 30 ºC population declined up to 81.6%. Composts were prepared using forest residue and rice straw after mixing with cow dung. Alleviation of pH effect on growth of tomato was noticed by amending different composts under glass house trial. Composts and rice biochar treated tomato plant, maximally increased the shoot length (33.6%, 31.8%), root length (30.2%, 27.8%), shoot fresh weight (47.9%, 55.4%), root fresh weight (50.8%, 59.0%), shoot dry weight (71.0%, 51.8%), root dry weight (69.1%, 52.1%), chl a (2.24 fold, 2.83 fold), chl b (2.83, 2.41), N (67.2%, 61.3%), P (65.1%, 64.3%), K (59.6%, 29.1%), Na (56.3%, 33.8%) and Ca (33.8%, 32.6%) content under water stress and irrigated conditions, respectively when compared to their untreated control. Under water stress condition, increase in proline content (3.14 fold), SOD (2.16 fold,), CAT (2.53 fold) and POD (1.89 fold) activity was recorded when compared to its untreated control. Compost prepared from Azadirachta indica showed maximum increased in chitinase (8.53 fold), glucanse (5.80 fold), SOD (2.18 fold), CAT (2.85 fold) and POD (2.93 fold) activity under Ailternaria solani infection. Thus present study imply that carrot peel and pea peel wastes can efficiently support the bioethanol and T. Harzianum spore production and composts prepared from wastes, improve plant growth under different soil conditions, water stress and pathogen infection.
