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.

    Micromorphology and distribution of Trichomes in the family Fabaceae Lindl.
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Gauri; Rawat, D.S.
    Fabaceae, also called Leguminosae or pea family, is the third largest Angiosperm family with about 741 genera and 20200 species on Earth. Large number of Fabaceae members exist in Pantnagar area and a study of trichomes of 26 species was conducted during 2018-19 to understand diversity in structure of trichomes and distribution of trichomes on different surfaces. Different surfaces of plant parts- stem, petiole, rachis, both surfaces and margins of leaf or leaflets, stipule, bract, sepal, petal, androecium, gynoecium, pod, were examined under light microscope for the presence, distribution and structural diversity of trichomes. Studied species belongs to 4 subfamilies of Fabaceae following recent and highly phylogenetic system of legumes by Legume Phylogeny Working group. All 26 species bear trichomes on any one or more surfaces examined. Gynoecium bear trichomes in maximum (20) species, followed by sepal and leaf axes (19 spp.), and stem and leaves (17 spp.). Stamens bear trichomes in minimum number (5) of species. 32 structural types of trichomes were recorded of which 7 were glandular and 25 were non-glandular types. In 15 species trichomes are only non-glandular types whereas, 11 species bear both glandular as well as non-glandular trichomes. Non-glandular, unicellular, subulate (NU-subulate) trichomes are most common in Fabaceae and recorded in 16 species while among the glandular trichomes, glandular, multicellular, uniseriate, clavate (GMU-clavate) trichomes are more common and recorded in 7 taxa. Maximum seven types of trichomes were recorded in Bauhinia tomentosa. In Caesalpinia pulcherrima trichomes are present only at the base of filaments. In family Fabaceae trichome structure and distribution were found useful for differentiating species within genera thus proves their systematic utility. The study concludes that wide variety of trichomes exists in Fabaceae, though the exact role of trichomes is yet to be ascertained. Presence of trichomes on gynoecium in more than two-third species suggests their role in protection of developing pods and seeds by warding off creeping insect pests.

    Diversity of bryophytes in Berinag (Uttarakhand), Kumaun Himalaya
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Dhami, Deeksha; Chaturvedi, Preeti
    Bryophytes are the cryptogamous, herbaceous plants generally found in a transition zone between the land and water. Bryophyte cover of an area is a clear indication of the health of the ecosystem. These archegoniates constitute 5.62% of total plants of India. Luxuriant forests, varied topography and suitable climatic conditions made Kumaun Himalaya rich in bryophyte diversity. Nature’s furies and human interference have, however, started posing a toll on the diversity of the region. Hence, taxonomy and documentation of its flora is essential for conservation and management of the biodiversity. Present study was an attempt to survey, collect and taxonomically describe the bryoflora of Berinag region including the villages and forest of Berinag. In the investigation, total of 33 species were reported, out of which eight were liverworts and 25 were mosses. Out of 25 mosses, 15 mosses were acrocarpous and 10 mosses were pleurocarpous in habit. Liverworts species belonged to six genera of five families and two orders whereas mosses belonged to 24 genera of 17 families and eight orders. Out of the 10 orders dealt in the present work, Hypnales was the largest consisting of seven families, nine genera and nine species followed by Dicranales and Marchantiales both consisting of three families, five and four genera respectively. In mosses, Bryaceae was the dominant family consisting of three genera and four species followed by Calymperaceae, Leucobryaceae, Anomodontaceae, Leskeaceae and Polytrichaceae. In liverworts, Aytoniaceae was found dominant. Marchantia, Frullania and Bryum were the dominant genera of the region. Majority of the taxa were terricolous in habitat.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-06) Thakurathi, Gayatri; Rao, P.B.
    Medicinal herbs offer an important traditional way to prevent and cure several diseases. Various anti-inflammatory drugs have been used to reduce pain and inflammation. However, there are many side effects associated with non- steroidal drugs. Therefore, a search for non-toxic natural compounds with antioxidant activity has intensified in recent years. In the present study, nine wild plant species of family Lamiaceae were selected to assess their antioxidant and anti-inflammatory potential. The extraction yield (%) was maximum in Pogostemon benghalensis (21.01) and Vitex negundo (18.71) in aqua-methanol and aqua-acetone, respectively. All the phytochemicals are present in all the species except saponins present in Clerodendrum infortunatum, Colebrookea oppositifolia and V. negundo; terpenoids were absent in Roylea elegans. In both aqua-methanol and aqua-acetone, the values in different plant species was maximum in C. oppositifolia in terms of DPPH (80.17 and 70.35 %), FRAP (109.38 and 83.72, μg BHTE/mg), FCA (57.1 and 54.55 μg BHTE/mg) and TAA (116.13 and 69.95 μg VCE/mg) assays, respectively. The TPC (μg GAE/mg) was maximum in C. oppositifolia (36.10) and P. benghalensis (30.20) in aqua-methanol and aqua-acetone, respectively while the TFC ((μg QE/mg) was maximum in V. negundo (41.93 and 44.266) in both aqua-methanol and aqua-acetone. The IC50 values (μg/ml) of DPPH were comparatively higher in R. elegans (409.0) in aqua-methanol and Lamium amplexicaule (178.97) in aqua-acetone and low in C. oppositifolia (26.17 and 41.08 in aqua-methanol and aqua-acetone, respectively); and IC50 values of FCA ranged from 106.13 (C. oppositifolia) to 594.69 (V. negundo) in aqua-methanol; and 111.608 (C. oppositifolia) to 676.48 (R. elegans) in aqua-acetone. Anti-inflammatory potential against protein denaturation (%) was comparatively higher in C. oppositifolia in both aqua-methanol (73.93) and aqua-acetone (64.78) than other species. Among the solvents, aqua-methanol showed comparatively higher antioxidant activity than aqua-acetone. Positive and significant correlation in terms of FRAP, DPPH, FCA, TAA and TPC was obtained in all species. Thus, the above mentioned plant species with comparatively higher antioxidant and anti-inflammatory potential than the others and can be a potent natural plant source of nutritional and anti-inflammatory drugs which can be utilized for developing natural curatives against synthetic ones. It can be exploited in nutraceutical and pharmaceutical industries.

    Effect of organic mulching and spacing on growth and yield of chamomile (Matricaria chamomilla L.) cv. Cim Sammohak
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-06) Joshi, Shubham; Bisht, P.S.
    Chamomile (Matricaria chamomilla L.) belonging to family Asteraceae is one of the essential oil producing medicinal plant. Dry flowers of chamomile are mainly used for essential oil extraction. However, the production of dry flowers remains low due to lack of appropriate agronomic practices. The aim of present experiment was to study the “Effect of Organic Mulching and Spacing on Growth and Yield of Chamomile (Matricaria chamomilla L.) cv. CIM Sammohak”. This experiment was carried out at Medicinal Plant Research and Development Centre, Govind Ballabh Pant University of Agriculture & Technology, Pantnagar, Uttarakhand, India, during November 2017 to April 2018. The experimental design was Split Plot Design with three replications. There were four types of mulches; no mulch, rice straw, black gram straw and barnyard millet straw with three spacing; 30×30 cm, 30×20 cm and 30×10 cm. Mulches were assigned to main plots and spacing was allotted to sub plots. The organic mulching rate of application was 5 ton ha−1 and this was applied in the field after transplanting. Different vegetative, floral, oil, soil and weed parameters were analyzed. Flowers were picked and counted after two successive florescence. The analyzed results showed that, organic mulch and spacing had significant effect on different parameters. Interaction results showed that, highest dry flower yield was recorded under Rice straw with 30×10 cm spacing (1,304.44 kg/ha) and maximum essential oil was recorded under Barnyard millet straw with 30×10 cm plant spacing (6.74 kg/ha). Mulch also increased the soil moisture, decreased soil surface temperature and suppressed weeds for better growth of the crop.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Tamta, Ritika; Rawat, D.S.
    Fabaceae, also called Leguminosae or pea family, is the third largest family among the angiosperms with 741 genera and 20200 species on Earth. Contemporary scientific literature accept three subfamilies and 36 tribes in the family though recent classification by Legume Phylogeny Working Group has proposed six subfamilies in Fabaceae and placed earlier subfamily Mimosoideae embedded in Caesalpinioideae. Trichomes are invariably present on the legume species. Large number of Fabaceae members exists in Pantnagar area and a study of trichomes of 53 species and one subspecies belonging to 39 genera, 18 tribes and 3 subfamilies was conducted during 2017-18. Thirteen different surfaces of plant parts- stem, petiole, petiolule, both surfaces of leaf or leaflet blade and its margin, stipule, rachis, sepal, petal, gynoecium, androecium, pod, were examined for presence and types of trichomes. One species Caesalpinia pulcherrima was found completely glabrous while 31 types of trichomes were recorded in 53 examined taxa. Trichomes were recorded on leaf or leaflet blade in 48 taxa, on stem in 45 taxa, on petiole in 44 taxa, on gynoecium in 41 taxa, on sepals in 39 taxa, on rachis in 37 taxa, on stipule in 35 taxa, on petiolule in 27 and on petals on 15 taxa. Only non-glandular trichomes were recorded in 22 species while rest 32 taxa bear both, non-glandular and glandular trichomes. Non-glandular unicellular subulate trichomes are widespread in Fabaceae and recorded in 29 taxa while glandular multicellular clavate trichomes are most common secretary trichomes recorded in 16 taxa. Maximum five types of trichomes were recorded on Phaseolus vulgaris and Desmodium gangeticum. In family Fabaceae trichome structure and distribution were found useful for differentiating subfamilies, tribes, genera and species of studied taxa thus proves their systematic utility.

    Assessment of antioxidant and anti-inflammatory potential of ten selected conventional medicinal plant species
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Thapliyal, Neha; Rao, P.B.
    Regardless of the advent of modern high throughput drug discovery and screening procedures, traditional medicine remains as the most affordable source of treatment with minimal side effects. In this regard, antioxidants inhabiting the plant tissues have become a major area of research as they are known to sufficiently stable free radicals and neutralize them. In the present study, ten conventional medicinal plant species were selected to assess their antioxidant and anti-inflammatory potential. In all selected plant species, the yield, antioxidants and anti-inflammatory activities were comparatively higher in methanol than in acetone extracts. In both methanol and acetone, DPPH activity (%) was maximum in Ziziphus mauritiana (91.93and 81.49) and FRAP (μg TE/mg) in Ocimum gratissimum (132.74 and 89.18, respectively); whereas TAA (μg VCE/mg) was highest in Z. mauritiana (293.18) in methanol and Achyranthes aspera (77.56) in acetone. The IC50 values (μg/ml) of Bauhinia variegate (70.51) and Z. mauritiana (60.14) were close to BHT (57.38). The TPC (μg GAE/mg) was highest in Z. mauritiana (98.54) and B. variegata (48.76) in methanol and acetone, respectively; while TFC (μg QE/mg) was maximum in Alternanthera ficoidea (25.23±012 in methanol and 19.35±0.27 in acetone). Anti-inflammatory potential against albumin denaturation (%) was comparatively higher in O. gratissimum in both methanol (35.12) and acetone (29.26) than other species. Furthermore, positive correlation was obtained between TPC-DPPH, TPC-FRAP and DPPH-FRAP, while other combinations showed no correlation. Thus, the present findings lay a scientific foundation that the above plant species with comparatively higher antioxidant and anti-inflammatory potential can be utilized by pharmaceutical and nutraceutical industries for developing natural curative and dietary substitutes against synthetic ones with boundless availability.

    Evaluating the impact of Plant Growth Promoting Rhizobacteria (PGPR) on rice (Oryza sativa L.) and wheat (Triticum aestivum L.) cropping system
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Kothari, Deepali; Sharma, A.K.
    Current study was carried out to demonstrate the effect of seed bacterization with two bacterial inoculum Variovorax paradoxus (RAA3) and Pseudomonas palleroniana (DPB16) on growth and nutrient content of rice and wheat under drought and irrigated condition as well as in presence or absence of green manure (Sesbania). These two bacterial strains contain 1-aminocyclopropane-1-carboxylate (ACC) deaminase that plays a crucial role in alleviation of drought stress. A significant positive effect on growth and nutrient content was observed in case of rice and wheat cultivars after inoculation with RAA3 and DPB16 as compared to control of respective cultivars. Strain RAA3 and DPB16 treated plants in presence of Sesbania, significantly increased the grain yield/m2 in rice (11.2%, 9.8%) respectively over control, while in drought condition the grain yield/m2 was enhanced by 13.35% in RAA3 and 6.8% in DPB16 treatment. In case of wheat, strain RAA3 and DPB16 increased the grain yield/m2 in presence of Sesbania, by 20.61% and 10.30% over control while in drought condition the grain yield/m2 was enhanced by 24.7% in RAA3 treatment and by 10.5% in DPB16 treatment. It was also observed that treatment RAA3 under drought condition had more grain yield than control of irrigation condition by 4.88% in rice and 3.92% in wheat. Presence of organic manure along with PGPR inoculum increased the grain yield of rice and wheat by (8.7% and 8.3%) in RAA3 and (13.2% and 9.2%) in DPB16 treatment respectively. However in another experiment, it was found that PGPB treated plants increased yield significantly by 41.04% in RAA3 and 42.28% in DPB16 over control. RAA3 also showed better responses towards germination count (24.94%) as compared to control under glass house condition. On isolation of endophytic bacteria from rice, 84 morphologically different bacteria were isolated from various plant parts of three varieties of rice i.e. Swarna, Sahbhagi and IR64; out of which 54 isolates showed to have phosphate solubilising activity, 40 bacterial isolates were capable of fixing nitrogen, and 51 isolates were found to be positive for siderophore production. This finding may imply RAA3 and DPB16 in presence of Sesbania could turn out to be effective inoculants for improving the growth of plant.

    Diversity of the Family Malvaceae Juss. (Sensu APG-III) in Pantnagar
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-07) Karnatak, Manish; Rawat, D.S.
    Angiosperm are the most diverse group on earth with 2, 73,174 species on earth. Malvaceae (sensu lato) with 250 genera, 4200 species, is the twelfth largest family of Angiosperms. Malvaceae (s.l.) of recent systems of classifications includes four traditional families Malvaceae (s.s.), Bombacaceae, Sterculiaceae, Tiliaceae which have been merged together. This Malvaceae is divided into 9 subfamilies i.e. Grewioideae, Byttnerioideae, Sterculioideae, Tilioideae, Dombeyoideae, Brownlowioideae, Helicteroideae, Malvoideae and Bombacoideae. A detailed floristic work carried out in Pantnagar during 2012- 2013 indicated that from these nine subfamilies, seven subfamilies (except Tilioideae, Brownlowioideae) are present in Pantnagar and represented by 25 genera, 40 species. The largest subfamily is Malvoideae, which is represented by 12 genera 22 species. Out of these 12 genera Hibiscus is represented by 5 species, Abelmoschus, and Sida each represented by 4 species while rest genera are represented by single species. The smallest subfamilies are Helicteroideae and Bombacoideae each represented by a single genus having single species. Among the total 40 species of Malvaceae (s.l.) 29 species are wild which indicates that major part of the flora (29 species) is made up of wild species while rests 11 are cultivated. Out of these 29 species, 7 species are invasive alien plant species. Nativity analysis indicates that most of the Malvaceae (s.l.) members occurring in the study area are Asian continent elements (47.5%, 19 species), followed by American elements (15%, 6 species), African elements (12.5%, 5 species), European element (2.5%, 1 species). Rest (22.5%, 9 species) are “wides” in relation to their origin.
