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.

    Morpho-physiological and biochemical assessment of heat tolerance in various rice (Oryza sativa L.) genotypes
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-02) Thakur, Roshan Suresh; Shankhdhar, S.C.
    Rice is a staple food crop in global food system fulfilling the energy requirement of major part of world population. It is very sensitive to environmental factors such as temperature, light, drought etc. during critical stages of growth, such as flowering and seed development. High temperature can irreversibly damage the rice grain quality, yield and plant processes. A research investigation was carried out to evaluate the effect of high temperature stress on morphophysiological and biochemical parameters; and to study the yield attributes of different rice genotypes under heat stressin B1 block of N. E. Borlaug crop research center, Pantnagar during kharif season 2019. Heat treatment was given to different rice genotypes during flowering by making a polythene tunnel in one block which traps heat and other block kept open as control. Both the ends were open for sufficient ventilation. Among 30 genotypes only five genotypes, viz., Vandana, IET 28417, N-22, IET 28409 and IET 27908 were selected for the further research work on the basis of their sensitivity to high temperature and on yield attributes. Parameters such as plant height, effective tiller number, total dry matter, leaf area index, chlorophyll content, chlorophyll fluorescence, stem weight, panicle weight, number of filled grains per panicle, number of spikelet, spikelet fertility, test weight, grain yield, harvest index, total carbohydrate and protein content of harvested seeds etc. were recorded. It was found that chlorophyll fluorescence, leaf weight, stem weight, panicle weight and TDM reduced after flowering. At maturity, there was a decrease in shoot weight, TDM, panicle weight, spikelet fertility, grain yield, harvest index andproteindue to high temperature. Physiological and biochemical analysis revealed that the carotenoid content and LAI were increased in all; whereas, carbohydrate, chlorophyll a, chlorophyll b content, test weight, spikelet number, grain number, panicle number, effective tillers and plant height were increased/decreased in some genotypes. The parameters which were positively correlated with grain yield were leaf weight, stem weight, panicle number, panicle weight, shoot weight, and TDM whereas test weight was negatively correlated. Genetic diversity was responsible for the stress effects and stress mitigation in the crop as different genotypes from diverse backgrounds showed varied results; since, out of five genotypes, IET28417 was found to be tolerant while IET 27908 and Vandana were sensitive to high temperature in the present investigation.

    Influence of different agroforestry tree species on soil properties and their potential for carbon sequestration in tarai region of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-11) Melkani, Suraj; Singh, Veer
    A field study was carried out during 2019-2020 at Agroforestry Research Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, to study the influence of different agroforestry tree species on soil properties and their potential for carbon sequestration in tarai region. The experiment comprised of nine agroforestry tree species viz., Anthocephalus cadamb, Pterospermum acerifolium, Delonix regia, Terminalia chebula, Chukrasia tabularis, Dillenia indica, Bambusa vulgaris, Lagerstroemia indica and Pithecellobium dulce along with a control in randomize block design with three replications. Soil samples were collected prior to the commencement of the monsoon season at 0-15 and 15-30 cm depth. All soil properties were significantly affected by the tree plantations and except bulk density, pH and electrical conductivity of soil all other parameters decreased at 15-30 cm depth of soil compared to 0-15 cm. There was slight decrease in the pH of soil under tree covers, whereas no appreciable change in EC was observed. Compared with control (fallow land), all the soil properties found to be improved under different tree covers at both the depths. Among the different agroforestry tree species, Bambusa vulgaris planted soil showed the higher values of most of the soil properties however lowest values were found under other tree species. Different agroforestry tree species stored 47.18-101.77, 2.39-6.43 and 19.10-35.21 kg ha-1 more available N, P and K, respectively, over the fallow land at soil surface layer where maximum accumulation was found with Bambusa vulgaris for available N and Anthocephalus cadamba for available P and K. Very labile carbon fraction was observed about four and two times higher than less labile and labile and non labile carbon fraction, respectively, where highest amount of non labile carbon fraction was obtained under Dillenia indica plantation soil while other carbon fractions under Bambusa vulgaris plantation at both soil depths. Soil microbial biomass carbon, soil organic carbon content, SOC stock, carbon sequestration rate were higher under Bambusa vulgaris which was 45.08-149.21 μg g-1 of soil, 0.52-3.08 g kg-1 soil, 0.66-3.55 Mg C ha-1 and 0.098-0.586 Mg C ha-1 yr-1, respectively, more than other treatments. Compared to the initial level of 16 years back, available N, P and K, soil organic carbon content and SOC stock in terms of per cent were found to increase and was in the order of available P > SOC content > available N > available K > SOC stock. All the correlations between the soil properties in general were observed as significant. Highest significant positive and negative correlations were observed between SOC and SOC stock (0.991**) and soil bulk density and available N (-0.955**), respectively. Therefore, it is evident from the present study that agroforestry is a suitable land-use system in improvement of soil carbon storage, carbon sequestration as well as for the overall improvement of soil health through improvement in soil properties. The adaptation of Bambusa vulgaris in the agroforestry plantation system in tarai region may be beneficial.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-12) Dhyani, Ajay; Pal, Anju
    The present investigation entitled “Varietal evaluation of Dahlia (Dahlia variabilis L.) under tarai conditions of Uttarakhand” was carried out at the Model Floriculture Centre, G.B Pant University of Agriculture and Technology, Pantnagar during 2019- 20. The experiment was laid out in complete randomized block design with three replications involving 10 genotypes. The aim of the experiment was to evaluate these ten different varieties of Dahlia on the basis of their growth and flowering parameters. Present findings revealed that among all the varieties of Dahlia cultivar Jishu showed highest plant height (113.22cm), plant spread (62.67 cm) and internodal distance (15.12 cm) whereas maximum number of leaves was found in cultivar Sohini (135.44). Matungini cultivar of Dahlia has maximum number of primary branches (10.11) and leaf diameter (11.78 cm). Maximum number of flowers per plant was observed in cultivar Matungini (14.78). Maximum flower diameter was recorded in the cultivar „Tenzin‟ i.e. 19.44 cm. The maximum fresh flower weight was observed in cultivar „Jishu‟ that was (55.90 gm). Maximum vase life was observed in the cultivar „Shanti‟ (6.6 days). It was observed from the experimental results that Jishu and Matungani variety was well suitable for cultivation in tarai regions of Uttarakhand during winter season period whereas the cultivar Kenya Yellow can be found well suited for pot culture purpose. The flowering in Kenya Yellow was very late as compared to all other cultivars. The plant height, number of branches and number of leaves were also found to be significantly correlated with the bud formation in the Dahlia plants. Overall performance of all the cultivars was the influence of its heritability and environmental conditions.

    Eco-friendly management of gram pod borer, Helicoverpa armigera (Hubner) on chickpea
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-07) Bisht, Dheeraj; Tiwari, Ruchira
    Field and laboratory experiments based bioassay studies were made to evaluate the efficacy of cow urine based natural formulations, such as desi cow urine @20 percent, agniastra, neemastra dashparni, jivamrit and panchgavya @3 percent, and the effectiveness of homemade jaggery-based sweet traps at different concentrations against H. armigera on chickpea during the rabi crop season of 2018-19 at NB Crop Research Centre, Pantnagar, Uttarakhad. The field studies showed that, agniastra, dashparni, neemastra, desi cow urine and jivamrit were effective against H.armigera with mean larval population, pod damage and grain yield ranged from 1.89 to 4.17larvae/10 plants, 13.43to 22.33 per cent and 7.32 q/ha to 11.95 q/ha, respectively in comparison with untreated control which was significantly different r than these treatments (10.05 larvae/10 plants, pod damage-38.70 per cent and grain yield-6.44 q/ha). These cow urine based natural formulations were also found safe for the natural enemy, Campoletus chloridae during field study with the mean cocoon population ranged from 1.50 to 3.00/10 plants in comparison to insecticide, indoxcarb (0.67/10 plants). The efficacy of the jaggery based sweet baited traps was also evaluated to trap the adult moths of H. armigera on chickpea crop. The jaggery solution @ 50% and 75% were found to be the best to trap the moths of H. armigera (17.78 adults/ trap) and (20.67 adults/trap), respectively which was at par with Helilure pheromone trap (24.11 adults/trap) with trappings of lesser numbers of non-target insects in the chickpea crop environment. Laboratory based bioassay studies on the growth regulatory effect of various cow urine based natural formulations again demonstrated the effectiveness of agniastra, dashparni, and neemastra against H. armigera caused 100% mortality of neonate larvae, while desi cow urine, panchgavya and jivamrit gave very less growth index values (0.452, 0.521 and 0.842) compared to untreated control (2.546). The studies conducted on antifeedant activity of cow urine based formulations against 4th instar larvae of H. armigera categorized agniastra and neemastra with strong antifeedant action with a preference index of 0.50, each. Among the other treatments, desi cow urine, dashparni and jivanrit with a preference indices ranged from (0.55 to 0.73) were found to be moderately antifeedant action while panchgavya (076) was recorded with slight antifeedant action against the test insect. On the basis of the above findings, the present study clearly showed that the tested cow urine based natural formulations and homemade jaggery based sweet traps were found very effective against H. armigera on chickpea crop system. On the other hand, the growth regulatory and antifeedant activity of these cost effective, easily made and eco-friendly cow urine based natural formulations showed their negative effect on feeding behavior, growth and development of H. armigera. Thus, it can finally be concluded that these eco-friendly approaches can easily be incorporated in an integrated pest management programme of H. armigera on chickpea.

    Variability and management of Fusarium oxysporum f.sp. lentis causing wilt of lentil
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Arya, Anshul; Kushwaha, K.P.S.
    Lentil (Lens culinaris Medic.) is one of the oldest annual grain legumes consumed and cultivated in the world. The origin of lentil is South West Asia. India is the second largest producer of lentil after Canada. Wilt disease of lentil, caused by the soil and seed-borne fungus Fusarium oxysporum Schlecht.emend.Snyder &Hansen f.sp. lentis Vasudeva & Srinivasan is one of the most severe and prominent diseases of the lentil. The continuous prevalence of this disease makes it most important to manage during lentil cultivation. The present investigation was undertaken to study prevalence of wilt in selected lentil growing areas of Uttarakhand and Uttar Pradesh. The morphological and molecular characters of the twenty-two pathogen isolates were studied along with the evaluation of ecofriendly management practices viz; Botanicals, Animal Products, Bioagents, Oils, Medicinal Mushrooms, Spent Mushroom Compost, Synthetic Defense Inducers, fungicides, and host resistance against the pathogen under in vitro and in vivo conditions during the Rabi season 2016-17 and 2017-18. The prevalence of the wilt disease was 100 percent along with a maximum 25 percent of disease incidence in all twenty-two lentil growing areas surveyed. The fungal pathogen and its isolates were isolated on the PDA medium from roots of infected plants showing peculiar disease symptoms like yellowing, withering, and drying. After morphological identification of the fungal pathogen, isolates were further genetically identified through the universal primers ITS1 and ITS4, as Fusarium oxysporum and accession no. MK452341 was obtained for the Pantnagar isolates from NCBI. Variation in pathogenic behavior of the isolates was also observed under glasshouse conditions and isolates were categorized as highly and extremely pathogenic in their behavior. Huge variation in the morphological characteristics of the isolates was observed based on the cultural growth, pigmentation, size, and shape of conidia. At the molecular level twenty-two isolates of the pathogen with ISSR (8 primers) and SSR (5 primers) primers showed significant genetical variation with 100 percent polymorphism. PIC value for the different ISSR primers was ranged from 0.65 to 0.93 and the PIC value for the SSR primers varied from 0.68 to 0.87 that showed high level of genetical variability among the isolates. The leaf extracts of Bael and Eucalyptus were found highly significant to inhibit the pathogen growth as well as reducing the disease incidence at 30 percent concentration under in vitro and in vivo conditions. The phytochemical Eucalyptol and 1,2 Diisopropenylcyclobutane were found responsible for the antifungal activity of the plant extracts of Eucalyptus and Bael, respectively, through GCMS analysis. Among the screened animal products, cow urine with 20 percent was performed best under in vitro and in vivo conditions. Badri cow urine was found superior over Sahiwal urine and gave 100 percent inhibition in the radial growth of pathogen, at 20 percent concentration under in vitro conditions. Seed treatment with cow urine was found an effective method for management of the disease in field conditions. The induction of defense-related enzymes PAL and Catalase were found maximum at 48 hours with 7 percent concentration of Badri cow urine. Panchgavya at 15 percent concentration gave 100 percent inhibition in the radial growth of the pathogen under in vitro condition. Induction of defense-related enzymes PAL and Catalase at 3 percent concentration of panchgavya was observed at 24 hours after challenged inoculation. Seed treatment with 5 percent concentration of panchagvya showed minimum disease incidence. Trichoderma harzianum (Strain Th14) gave 70 percent inhibition in the radial growth of the pathogen. PB3 at 1.0 percent induced the defense-related enzymes PAL, PO, PPO and catalase at 48 hours after challenged inoculation of the pathogen. The seed treatment with PB-2 @ 6g/kg seed and PB-2 at 0.5 percent concentration was found most suitable for soil drenching. The medicinal mushrooms (Ganoderma lucidum) was also found effective in inhibiting the radial growth of the pathogen and seed treatment with 30 percent extract of Ganoderma lucidum was showed minimum disease incidence. Mustard oil at 20 percent concentration inhibited the radial growth of pathogen under in vitro condition as well as 20ml/kg seed of it decreased the disease incidence under in vivo conditions. Application of 25 ton/ ha of Spent Mushroom Compost in the field was found effective in managing the disease. SA at 0.03 percent was found most effective in inducing the defense-related enzymes PAL, PO, PPO, and Catalase under glasshouse condition. Seed treatment with a combination of SA and BTH (1:1) at 0.1 percent concentration was found best for reducing the disease incidence. Tebuconazole was found most effective in reducing the radial growth (100% inhibition) of the pathogen under in vitro conditions at 0.05 percent concentration. Seed treatment with Tebuconazole or Propiconazole at the rate of 0.1 percent was found most effective in managing the disease under field condition. Germplasms, DL16-5, DL16-7, VL152, IPL339, IPL340, PL237, RL7-3, RVL15-5, IPL227, IPL338, IPL332 were found highly resistant against the wilt disease of lentil. These germplasms can be utilized for the cultivation of lentil crop and also in the resistance breeding program as the donor parent.

    Performance and emission characteristics of diesel engine using Lemongrass oil, Jatropha biodiesel and diesel oil blends
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Mohd Irshad; Tewari, P.C.
    Due to the sudden rise in prices and increased awareness of the harmful effects of crude oil on the environment, biodiesel, considered an environmentally friendly source of energy, has become too important as an alternative fuel in recent years. Energy resource demand is rising at a very rapid rate and demand for liquid fuel in the transport sector is very high. Biodiesel is therefore considered seriously as an alternative fuel for the diesel engine. Lemongrass oil is used as an alternative fuel for the diesel engine in the present study, the Jatropha biodiesel. Jatropha oil is first converted to biodiesel using reaction esterification and transesterification to enhance its different properties. In the presence of H2SO4 (1%) and KOH (1% by weight) as a catalyst, methanol (13% by weight) is used as alcohol. Using esterification and transesterification reactions, 94% of biodiesel yield is obtained. The performance, combustion and emission characteristics of a 4.4 kW, single cylinder, four stroke diesel engine, when fuelled with Jatropha biodiesel, Lemongrass oil and its 10-10%, 20-20%, 30-30%, 40-40%, 5-5%, 15-15%, 25-25%, 50-50%, 20-40%, 40-30%, 60-20% and 80-10% blends (on a volume basis) with diesel are investigated and compared with that of the standard diesel. Various experiments have been conducted at a fixed engine speed of 1500 rpm and at 25%, 50%, 75%, and 100% load. The main study is conducted with the aim of increasing the different parameters and characteristics of engine performance by using different selected blends of Jatropha biodiesel, Lemongrass oil with diesel. The parameters of engine performance such as brake power, brake-specific fuel consumption, brake thermal efficiency, smoke density, absorption coefficient, and exhaust temperature were measured and the optimum blends that gave these parameters the best results were investigated. The diesel engine blends L30J30D40 and L40J40D20 are obtained as the best blended fuel. The results of the experiment have been analyzed and compared with standard diesel. It is observed that there is a slight improvement in the combustion and emission characteristics of the engine by using some blends. It is also concluded that biodiesel and it's all blends show approximately similar properties to that of diesel fuel, thus they provided satisfactory results on the engine. The exhaust gas emissions of biodiesel and its all blended fuel types are also found better than that of diesel fuel except at 100% load. Therefore, all these blends can be effectively and efficiently used as an engine fuel without any modifications in the engine.

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-06) Krishnakumare, B.; Singh, Saurabh
    The present study was to assess the level of financial literacy and financial inclusion among rural households of Tamil Nadu during the year 2018. 8 districts, 16 taluks and 32 villages were selected using multistage sampling technique and 20 respondents from each selected village were chosen randomly. Both primary and secondary data utilized were analyzed using descriptive statistics, Multivariate Analysis of Variance (MANOVA), Chisquare test, multidimensional index of financial inclusion and binomial logistic regression with the help of SPSS and STATA software. The study revealed that major proportion of respondents was at medium level of financial literacy. Besides, the results of MANOVA revealed that the variables such as income, education, parent/spouse education, employment status and financial inclusion were found to be having a significant impact on financial literacy. Also, respondents having income above Rs. 10 Lakhs having their parent/spouse with post graduate degree and being financially included had shown a significant impact on financial behaviour, financial knowledge and overall financial literacy respectively. Pearson Chi-Square test indicated that there existed a statistically significant association between independent variables (gender, income and employment status) and awareness level of financial inclusion schemes. Of the eight selected districts, Coimbatore had high level of financial inclusion. Besides, Ariyalur, Dharmapuri, Dindigul, Kanniyakumari and Trichy were categorized under above average. Kancheepuram was considered to be at below average level and the extent of financial inclusion in the district Villupuram was very low. The results of binomial logistic regression revealed that respondents being employed, being self-employed, having LPG connection through Direct Benefit Transfer, frequency of bus from village to town and financial literacy had shown a significant positive impact on financial inclusion. Whereas, being unemployed and distance of village from banks turned out to be influencing negatively on financial inclusion.

    Target vehicle tracking under occlusion for video surveillance
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-08) Joshi, Rakesh Chandra; Mathur, Sanjay
    With the rapid development corporate infrastructure, industrial establishments, educational institutes and residential premises are facing an increasing need to enhance their security. In this thesis, a hybrid target vehicle tracking algorithm for smart video surveillance is proposed. It aims to track an unidentified target vehicle’s motion in a secured campus even in case of occlusion (if any) and to detect if it exhibits any suspicious activity. The main contents of this thesis are as follows: Aiming at the tracking of a target vehicle and handling occlusions if any through Kalman Filter assisted occlusion handling technique, performance evaluation under different noise and illumination levels and finally suspicious activity detection technique for the tracked vehicle. The algorithm works through two periods namely tracking period (no occlusion) and detection period (in case of occlusion), thus depicting its hybrid nature. Kanade-Lucas-Tomasi (KLT) feature tracker governs the operation of algorithm during the tracking period, whereas, a Cascaded Object Detector (COD) of weak classifiers, specially trained on a large database of cars, governs the operation during detection period or occlusion with the assistance of Kalman Filter. The motion analyses and suspicious activity detection capabilities have been discussed separately. The algorithm’s tracking efficiency has been tested on six different tracking scenarios of increasing complexity in real time. Performance evaluation results under high noise and low illumination show that the tracking algorithm has good robustness. All tests have been conducted on the MATLAB platform. The validity and practicality of the algorithm are verified.
