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.

    COMPARATIVE STUDY OF APSIM-WHEAT AND CERES-WHEAT MODEL FOR PRECISION MANAGEMENT OF WHEAT CROP AND MITIGATION OF THE ADVERSE IMPACT OF CLIMATE CHANGE UNDER TARAI REGION OF UTTARAKHAND
    (G. B. Pant University of Agriculture & Technology, Pantnagar-263145, 2022-09-01) Pareek, Neha; Nain, A. S.
    Climate change impacts on wheat production has widespread and national ramifications for food and nutritional security. A field study was conducted during rabi2017-18 and 2018-19 at agricultural farm of G.B. Pant University forcomparative study of APSIM-Wheat and CERES-Wheat model for precision management of wheat crop and mitigation of adverse impact of climate change Tarai region of Uttarakhand. APSIM-Wheat and CERES-Wheat, which simulates yieldhas been calibrated for winter wheat using experimental dataof 2017-18 crop season.The calibration was performed against anthesis (DAS), physiological maturity (DAS), grain and biomass yield for the three treatments of sowing dates (viz.,15th November, 25th November and 05th December) , three levels of irrigation (number of irrigation five, four and three) for two wheat varieties (HD-2967 and PBW-502).The calibrated APSIM-Wheat and CERES-Wheat model were then applied to validate anthesis (DAS), physiological maturity (DAS), yield and biomass for rabi season of 2018-19 for the three treatments of sowing dates (viz., 15th November, 25th November and 05th December) , three levels of irrigation (number of irrigation five, four and three) for two wheat varieties (HD-2967 and PBW-502). The simulated output by the CERES-Wheat model found closer to the experimental field data therefore this model was applied for other two objectives. In this study sowing time and irrigation (number of irrigations) were optimised to get economical yield. A sowing window starting from last week of October (25th October) to the first week of December (06th December) was selected for optimization of sowing date. Crop sown in the first week of November produced highest grain yield followed by sowing in second and third week in the rabi season of 2017-18 and 2018-19.The optimum number of irrigations for wheat was also evaluated by CERES-Wheat model through projected irrigation scenarios. Present study revealed that in this region three irrigations are sufficient for optimum yield. This model also applied to predict the wheat biomass and yield in the year 2030, 2050 and 2080 and found that biomass and yield will be decreased in the future years due to increase in temperature and decrease in rainfall. In-situ moisture conservation, rainwater harvesting and recycling, and efficient irrigation water use are all important adaptation strategies to combat the adverse effect of climate change. Breeders will need to develop some short-duration varieties in the coming years by changing the genetic makeup of existing varieties. Early flowering (photo- and thermo-insensitivity), early maturity, and higher productivity should be characteristics of the new varieties. Identification of crops and varieties/ hybrids with high water use efficiency, adapted to temperature extremes and high concentration of CO2 is needed in this climate change scenario.

    Nuclear reactions relevant to fusion reactor candidate materials
    (G. B. Pant University of Agriculture & Technology, Pantnagar, Uttarakhand. PIN 263145, 2022-09) Navita; Joshi, G.C.
    There is a possibility to develop the fusion reactors which may offers the prospect of a long-term energy production. For the development of a fusion reactor the reactor material should have low radioactivity and high capacity to endure neutron flux. To predict material damages by nuclear reactions and model the reactor design, accurate and high-quality cross-section data are required. The present study is motivated to investigate the production cross-section of 53Mn due to neutron induced reactions on stable and unstable target nuclei as well as charge particle induced reactions on stable target nuclei with the help of a nuclear modular code TALYS-1.9. It is observed that neutron as well as charge particle induced reactions play an important role in the production of 53Mn. Moreover, the production cross-sections of 54Mn, 55Fe, 59Ni and 60Co via charged particle induced reactions have been calculated by TALYS-1.9. Default input parameters and all the six ldmodels have been used in the calculation of production cross-sections. The contribution of direct, pre-equilibrium and compound nucleus reaction to the total reaction cross-section are also studied and it is found that the contribution of compound nucleus reaction is high in comparison to direct and pre-equilibrium reaction. Energy differential cross-section (EDX) and double differential cross-section (DDX) of the natural Molybdenum for (n,xp) and (n,xα) reaction at 14.1 MeV neutrons energy has been calculated by optimizing input parameters of TALYS-1.9. From EDXs calculation, it is found that most of the outgoing protons and alpha particles have energy 5 MeV and 13 MeV respectively. DDXs calculated at 10º, 30º,60º, 90º and 120º shows anisotropical distribution of outgoing proton and alpha particles. In addition to the above, recoil spectra, displacement per atom cross-section and gas production (hydrogen and helium) cross-section for 90Zr, 93Nb, 98Mo, 180Hf, 181Ta and 184W have been calculated to estimate the reactor material damage. NRT method has been used to calculate displacement per atom cross-section. Recoil spectra show that (n,n’) and (n,2n) reaction channels are major cause to produce recoil nuclei. Gas production (hydrogen and helium) cross-section infers that production cross-section of hydrogen is higher than the production cross-section of helium. From above, it is concluded that nuclear modular code TALYS-1.9 is a powerful code to predict the cross-sectional data of long-lived radionuclides induce by neutron as well as charged particles and damage produced during reactor operation, which is important to develop fusion reactor design.

    (G. B. Pant University of Agriculture & Technology, Pantnagar, Uttarakhand. PIN 263145, 2022-08) Goswami, Riya; Jeena, A. S.
    The present investigation entitled “Stability analysis in advanced clones of sugarcane (Saccharum spp. complex)” was conducted with 18 advanced clones of Sugarcane including three checks viz., CoS 767, CoPant 97222 and Co 05011 to estimate the genotype×environment interaction and stability parameters using Eberhart and Russell model. The experiment was conducted in randomized block design at three different environments viz., Norman E. Borlaug Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar (E1), U.P Council of Sugarcane Research, Shahjahanpur (E2) and, PAU Regional Station, Kapurthala (E3). At each environment observations were recorded for fifteen yield and yield contributing traits viz., germination percent, tillers/ha, brix percent at 10 months, purity percent at 10 months, sucrose percent at 10 months, number of millable cane/ha, single cane weight (kg), cane diameter (cm), cane height (m), cane yield (t/ha), CCS yield (t/ha), brix percent at 12 months, sucrose percent at 12 months, purity percent at 12 months and CCS percent at 12 months. Analysis of variance at each environment revealed that genotypes exhibited highly significant differences for all characters under study. Further, the pooled analysis of variance over three environments also exhibited significant differences among genotypes for all the fifteen traits. The estimates of the environmental index showed that E1 was the most favourable environment for nine traits followed by E2 for seven traits and E3 for five traits. Based on the mean performance, CoPant 97222 was registered as the best check for nine traits followed by CoS 767 for six traits. Likewise, among the entries, Co17018 was found superior to best checks for seven traits, followed by CoH 17262 for six traits and CoS 17234 and CoPb 17214 for five traits. The G X E interaction was found significant for all characters except for two traits namely, purity % at 10 months and purity % at 12 months. Based on the estimates of stability parameters as per Eberhart and Russell model, CoPb 17214 was observed as stable genotype for all traits except tillers/ha. Similarly, CoS 17236 and CoH17261 were found stable for fourteen traits except cane yield t/ha. Likewise, among the checks, Co 05011 was found stable for all traits except for cane yield, here this genotype was responsive in favourable environment. Check, CoS 767 was found stable for all traits except for germination percent. Based on the study the clone Co17018 was identified stable for cane yield and sucrose percent at 12 months, along with superiority over all the three checks. Hence, this genotype can be recommended for cultivation over different environments. While, two clones viz., CoS 17234 and Co 05011 were found responsive for cane yield in favourable environment, hence these can be recommended for cultivation under resource rich environment.

    Epidemiology and management of downy mildew of vegetable pea incited by Peronospora viciae f. sp. pisi Sydow Boerema & Verhoeven
    (G. B. Pant University of Agriculture & Technology, Pantnagar, Uttarakhand. PIN 263145, 2022-09) Bathula, Jagadeesh; Singh, R. P.
    Downy mildew caused by Peronospora viciae f. sp. pisi (Sydow) Boerema & Verhoeven is a serious foliar disease of vegetable pea. It may cause yield losses up to 55 per cent in susceptible varieties. Seed treatment and foliar fungicides provide an effective means of disease management but when this management strategy combined with sustainable approaches, the disease can be managed successfully. In the present study, efforts were made to investigate the yield loss due to downy mildew, use of chemical and biological seed treatments to reduce seed borne inoculum, cost-effective chemical control through new molecules, effect of sowing, varieties and influence of weather parameters on disease development. Screening of vegetable pea germplasms against downy mildew was also undertaken. Maximum avoidable yield losses due to protection by foliar spray of Cymoxanil 8% + mancozeb 64% were found in Arkel (34.29%), followed by AP-3 (29.44%) on first date of sowing (17th November), while in PSM-3 maximum (23.52%) avoidable yield losses was found at 3rd date of sowing (1st December). Among the fungicides and biological seed treatments under glasshouse conditions, seed treatment with combination of Metalaxyl 35% WS + Bacillus subtilis var. amyloliquefaciens and Metalaxyl 35% WS + Streptomyces lydicus found to be the best with less disease incidence and severity. Seed treatment with Metalaxyl 35% WS and 2 foliar sprays at 15 days interval starting 30 days after sowing by Fluopicolide 4.44% + fosetyl-Al 66.67% WG @ 2000 g ha-1 provided the minimum disease severity (15.78 PDI) and highest yield (52.53 q ha-1) followed by Iprovalicarb 5.5% + propineb 61.25% WP @ 1600 g ha-1 and Famoxadone 16.6% + cymoxanil 22.1% SC @ 500 g ha-1 but, Famoxadone 16.6% + cymoxanil 22.1% SC provided highest net benefit cost ratio (2.22) followed by Cymoxanil 8% + mancozeb 64% WP (2.05). Lesser disease and higher yield were obtained from variety PSM-3 sown on 24th November. The maximum increase in downy mildew was recorded 40 days after sowing, and temperature range of 5.5-22.05°C and 55-96.05% relative humidity along with 7.5 mm rainfall favored the disease development. Disease severity was found to be positively correlated with minimum temperature and rainfall. Out of 89 vegetable pea germplasms screened under natural epiphytotic conditions, PSM-11, PCPGR-6091 and Selection-23 were found to be resistant, while Multi frozen, Pila Lubix, Little Marvel Lincoln, EFL-9, PSM-3, Pant Upahar were found to be moderately resistant to downy mildew.

    Assessment and optimization of energy requirement in major crops of Uttarakhand
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-12) Akanksha; Singh, T. P.
    The energy use pattern for wheat, sugarcane and major crop cultivation in Tarai region and maize cultivation in hilly region of Uttarakhand have been studied.Survey was carried under AICRP on EAAI utilising the performa designed for the purpose and data were acquired from specific farmers. The selected farmers were divided into different category according to their land holding. All categories of farmer use different energy sources in different unit operations according to their farm power availability. The calculation of used energy in performing all unit operations were done for different categories farmers. A total of 23933.47 MJ/ha of energy was found to be used in the cultivation of wheat crops by all categories of farmers. Fertilizer application accounted for the largest portion of the total input energy used 12149.32 MJ/ha (50.76%). The second highest overall energy contributor was irrigation, which is 4029.77 MJ/ha (16.84%), sowing operation involves 2916.54 MJ/ha (12.19%) of the total input energy used followed by 2100.01 MJ/ha (08.77%) of tillage. Harvesting and threshing operation involves 1847.77 MJ/ha (07.72%) and plant protection share 890.07 MJ/ha (03.72%) in total input energy.Average crop yield obtained by large, medium, semi-medium, small and marginal category farmer was 5494.86, 5350.88, 5126.81, 5126.40 and 4800.69 kg/ha respectively using the input energy of 25248.00, 24600.86, 23858.33, 23832.27 and 23504.98 MJ/ha respectively.The energy ratio for large, medium, semi-medium, small and marginal category was found as 6.68, 6.67, 6.42, 6.48 and 6.64 respectively. In Tarai region of Uttarakhand, for all categories of farmer growing wheat cropthe energy ratio was obtained as 6.55 with energy productivity of 0.21 kg/MJ. The average farm power availability was found 2.68 kW/ha.The total energy used in the production of sugarcane crop including all unit processes was determined to be 169.644 GJ/ha. The sowing operation accounted for the largest portion of the total energy use 142.041 GJ/ha (83.73%) to cultivate sugarcane crop. It was observed that the sugarcane cultivation required highest seed energy because of high seed rate used by farmers in the region. Total input energy for sugarcane accounts fertilizer energy 21721.94 MJ/ha (12.80%), tillage energy 2872.19 MJ/ha (1.69%) followed by irrigation energy 1002.15 MJ/ha (0.59%).Medium category farmer used input energy of 173.683 GJ/ha and obtained output energy of 1127.913 GJ/ha. Similarly, total input energy used by semi-medium, small and marginal category farmers was 171.234, 166.356, 162.407 GJ/ha respectively. The output energy obtained by semi-medium, small and marginal category farmers against the used input energy was 1029.819, 916.994 and 821.913 GJ/ha respectively. The overall energy ratio, of all categories of farmers in Tarai region of Uttarakhand,wasfound as 5.74 with energy productivity was 0.36 kg/MJ.According to the study the average farm power availability for sugarcane crop cultivation in Uttarakhand's Tarai region is 2.48 kW/ha. Total of 2903.97 MJ/ha of input energy was used by the marginal farmers to cultivate maize crops in hilly region of Uttarakhand. Fertiliser contributed the most at 1346.55 MJ/ha (46.37%) and machinery contributed the least 22.26 MJ/ha (0.77%). The second largest energy input contributor for the cultivation of maize was seed, which contributed 844.25 MJ/ha (29.07%) of energy. The output of maize is influenced by animal energy to the tune of 452.68 MJ/ha (15.59%). The amount of energy needed to cultivate maize is 238.23 MJ/ha (8.23%) which comes from human as source of energy.Average maize crop yield obtained by marginal category farmer was 1174.39 kg/ha using input energy of 2903.37 MJ/ha. Output energy obtained by marginal category farmers is 38179.36 MJ/ha against the used input energy in maize crop cultivation. Energy ratio obtained was 13.14 which indicated that with the consumption of lower amount of energy the yield and output energy obtained was high. Farm poweravailability in hilly area was observed as 0.42 kW/ha which is quite low mainly due to use of animal power as source and also due to least or no intervention of improved implement/machinery for performing unit operations.

    Response of wheat Triticum aestivum l. to tillage and nutrient management practices under rice-wheat system in Himalayan tarai
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-09) Yadav, Kamalkant; Yadav, Kamalkant; Singh, Rohitashav
    Field experiments entitled “Response of wheat (Triticum aestivum L.) to tillage and nutrient management practices under rice-wheat system in Himalayan tarai” were conducted in the D-2 block of Norman E. Borlaug Crop Research Centre, G. B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand) during the rabi season of 2020-21 and 2021-22. The objectives of investigation were to study the effect of tillage and nutrient management practices on the growth and productivity of wheat, nutritional and quality parameters, energy consumption and economics of different treatments. The experiment was laid out in a split-plot design with three replications. Treatments were consisted of three tillage practices viz. zero, reduced and conventional tillage and whereas, in sub-plots, five nutrient management practices viz. RDF (N 120:P2O5 60:K2O 40 kg/ha), RDF + FYM @5 t/ha, RDF + ZnSO4 @25 kg/ha, 75% RDF + FYM @10 t/ha and 75% RDF + FYM @5 t/ha) + ZnSO4 @12.5 kg/ha. The investigation revealed that tillage did not significantly influence growth parameters, yield attributing characters and yield but economics was significantly influenced in both years of study. Zero tillage recorded comparatively higher grain yield over reduced and conventional tillage practices. Zero tillage recorded 10.25 % and 11.52% higher net returns than conventional tillage, in 2020-21 and 2021- 22, respectively. The lowest energy competition was recorded under zero tillage as well as significantly higher net energy and energy efficiency was achieved by zero tillage over reduced and conventional tillage in both years. There was a significant impact of nutrient management practices on various parameters. Among the nutrient management practices, NM5 treatment recorded significant response to all the growth parameters at various growth stages which resulted in higher yield attributes (spike/m2, fertile spikelets/spike and grain weight/spike), N, P, K and Zn, total uptake and net return compared to NM1, NM2 and NM3. Significantly higher grain and biological yield, nutrient uptake in grain, gross monitory return, net energy return and energy efficiency in NM5 (75% RDF + FYM @5 t/ha + ZnSO4 @12.5 kg/ha) treatment compared with NM1 and NM2 but at par with NM4 and NM3 treatments. The increment in grain yield in NM5 i.e. 75% RDF + FYM @5 t/ha + ZnSO4 @12.5 kg/ha were (16.7 & 15.8%), (14.2 & 13.6%), (10.1 & 9.3%) and (6.7 & 6.2%), per cent more over NM1 (RDF 120:60:40), NM2 (RDF + ZnSO4 @25 kg/ha), NM3 (RDF + FYM @5 t/ha) and NM4 (75% RDF + FYM @10 t/ha) in 2020-21 and 2021-22, respectively. Therefore, in tarai regions, zero tillage plus 75% RDF + FYM + 12.50 kg/ha of ZnSO4 is a better option for achieving a higher wheat yield.

    Comparative study on nutritional composition of raw and germinated quinoa (chenopodium quinoa) flour and development of ready-to-eat (RTE) snack
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-09) M. Anuhya; Dobhal, Neetu
    Quinoa (Chenopodium Willd.) is a gluten-free nutrient-dense pseudocereal. In the present study, quinoa was germinated to observe its effect on physical and functional properties, nutritional and antinutritional content and total antioxidant activity. The results showed that germinated quinoa possessed good functional properties like water absorption capacity, oil absorption capacity, emulsion capacity and stability, foaming capacity and foam stability, which are beneficial in product development. Proximate analysis revealed that the crude protein and crude fiber content of germinated quinoa flour (13.6 and 7.16%) was higher than raw quinoa flour (13.4 and 4.01%). Moisture, total ash, crude fat and carbohydrate content of raw quinoa flour (11.01, 2.22, 5.2, and 64.15%) was higher than germinated quinoa flour (9.03, 1.55, 4.3 and 64.34%). Data on mineral composition revealed that germination of quinoa led to significant increase of 49, 33.87, 18.38 and 13% in iron, calcium, potassium and phosphorus, respectively. Dietary fiber and in-vitro protein digestibility of germinated quinoa flour was significantly higher than raw quinoa flour. The findings showed that all antinutritional factors decreased significantly on germination while antioxidant activity increased. Among the different combinations of whole wheat flour and quinoa flour for developing waffles, the waffles developed with 100% raw quinoa flour and 60% germinated quinoa flour were found most acceptable on the basis of sensory evaluation. One serving of 100% raw quinoa flour waffles and 60% germinated quinoa flour waffles provided around 9-13 % of RDA of energy and 17-26 % of RDA of protein for children of age 7-12 years. Therefore, it can be concluded that this nutrient-dense snack can be considered a healthy alternative in the fast changing world, where lifestyle disorders, especially in the children are becoming a major problem

    Improvement of voltage profile in distribution system using compensating devices
    (G. B. Pant University of Agriculture and Technology, Pantnagar, 2022-10) Pandey, Kamal; Singh, Sunil
    Optimal reactive power deployment in accordance with the statutory provisions of Indian Electricity Grid Codes is important for better performance of the system. Better voltage profile, lower losses, and improved efficiency are measures of distribution system quality. The aim is to keep the system operating smoothly with a better voltage profile at every node. A good distribution network is hence expected to improve overall efficiency of the system through loss minimization and power quality control. Due to the bidirectional nature of the present distribution system, DFACTS devices are gaining relevance almost everywhere for quick voltage management, power quality maintenance, and enhanced stability margins In this research work, a 33 bus distribution system of base 12.66 kV and 10 MVA is taken into consideration. After that, the improvement of voltage profile is discussed. By using load flow analysis, the values of unknown parameters are calculated. The impact of single and multiple D-STATCOM is investigated. The minimum voltage profile is improved to 0.9523 pu (5.18 % from base case) and 0.9780 pu (8.18 % from base case) from 0.9040 pu in single and multiple D-STATCOM cases respectively. The real and reactive power losses are reduced by 28.37 % and 27.55 % in single D-STATCOM case; while in the case of multiple D-STATCOM case, this reduction is 38.09 % and 37.02 % respectively. Overall, it is concluded that in this case, the D-STATCOM helps in improving the voltage profile by injecting a suitable amount of reactive power into the system.
