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 RC multi-storey building with bracings and shear wall
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-09) Joshi, Vijay; Vaneeta Devi
    When a tall building is subjected to earthquake under the action of lateral loads, providing a suitable lateral force resisting system has a significant effect on the performance of the RC frame structure. The present study focuses on the study of system based strengthening systems for RC frame structure. The effectiveness of different locations of shear wall and X bracing on the RC frame structure has been carried out. For this study, a G+9 storied RC frame structure has been considered and structural behavior has been studied for time history at Pin Code: 370020 (Bhuj, Gujarat, India) taken of 2001-01-26 at 03:16:40 UTC of magnitude (M7). The RC frame structure models are analyze by nonlinear dynamic time history as per IS 1893:2016(part1) using SAP2000 software. A comparative study has been performed on parameters namely, joint displacement, base shear, maximum bending moment, shear force and time period on the considered RC bare Frame and system based strengthening systems, thus, six number of models have analysed and compared. From the study, it has been observed that the joint displacement of the bare frame with shear wall on corner edge decrease in the structure as compared to the bare frame in seismic zone V. Base shear value increases in the strengthened RC frame in comparison with bare frame. Maximum bending moment, maximum shear force value and time period values in frame model with shear wall and X bracing get reduced as compared to frame model without them. In the present study, analysis of G+9 storey RC frame with and without system based strengthening has been performed by nonlinear time history analysis using SAP2000, conclusions inferred is that the shear walls configured with the shear wall on corner edge with bare frame have been found beneficial as compared with other models.

    Survey, identification and management of potato cyst nematode (Globodera spp.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-07) Joshi, Vijay; Satya Kumar
    Potato is an important root vegetable and staple food in world over. It is produced throughout the year in terrain and hilly regions of Uttarakhand and also plays a significant role in the economy of the state. Phytoparasitic nematodes are one of the limiting factors in potato production leading to a yield loss of 23%. Among phytoparasitic nematodes related to rhizosphere of Potato, the Potato Cyst Nematode (Globodera spp.) causes significant yield loss of up to 80% reducing the quality and quantity of the potato tuber. Keeping in view the importance of crop and visualizing the emergence of PCN in Uttarakhand extensive survey were conducted in nine districts of the state, focusing on major potato growing areas and GPSMF to assess the status of important phytoparasitic nematodes. The multilocation trials were conducted to study the effect of different altitudes, soil temperature and weather temperature on development of PCN Cyst at different locations followed by management experiments at GPSMF Balanti (Munsyari) to explore the effect of new chemical nematicides viz., Fluensulfone, Fluopyram and Fluazaindolizine and biological control agents viz., Pochonia chlamydosporia, Paecilomyces lilacinus, Pant Bioagent-1 (Trichoderma harzianum) and Pant Bioagent-3 (Trichoderma harzianum + Pseudomonas fluorescens). Survey studies revealed the presence of three cyst forming nematodes viz., Globodera spp. (G. rostochiensis and G. pallida), Cactodera spp. and Punctodera spp. along with eleven other genera of phytoparasitic nematodes viz. Meloidogyne spp., Ditylenchus spp., Pratylenchus spp., Helicotylenchus spp., Tylenchus spp., Tylenchorhynchus spp., Hoplolaimus spp., Trichodorus spp., Criconemoides spp., Xiphinema spp. and Aphelenchus spp. Three GPSMF viz., Balanti Farm, Tixen Farm (Munsyari, Pithoragarh) and Koti Farm Auli (Chamoli) were found to be highly infested with PCN. While, PCN was not observed in the soil samples of Bhattka Farm (Pithoragarh), Patwariya Farm (Almora), Dwari Farm, Kund Farm (Uttarkashi) and Khateda Farm (Champawat). Based on the morphological and molecular identification studies it was confirmed that there are two species of genus Globodera prevalent in Uttarakhand i.e., G. rostochiensis and G. pallida. Multilocation experiment studies revealed that reproduction factor of PCN is positively correlated to increasing altitude, while it is negatively correlated to increasing weather and soil temperature. Among nine locations, PCN cyst were developed in Gagar Farm (Nainital), Mukteshwar (Nainital), Nathuakhan (Nainital), Tixen Farm (Pithoragarh) and Shama Dana (Bageshwar). New nematicides molecules viz. Fluopyram @ 1000 ml/ha, Fluazaindolizine @ 0.06% and Fluensulfone @ 3kg a.i./ha effectively reduced PCN reproduction factor and subsequently increased Yield and Chlorophyll content as compared to Carbofuran. Biological Control Agents viz. Paecilomyces lilacinus, Pochonia chlamydosporia, Pant Bioagent-1 and Pant Bioagent-3 were more efficient in managing PCN as compared to chemicals reducing PCN reproduction factor and increasing yield and chlorophyll content.

    Design of high speed and low power clock controlled flip-flop in 90 nm CMOS technology
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-07) Joshi, Vijay; Tomar, Abhishek
    Increasing processor speed demands peripheral devices of high speed and low power consumption. Power consumption can be reduced by decreasing capacitance of the circuit. Proposed clock blocked flip-flop (CBFF) design uses only 11 transistors and blocks data path after a fixed time. This time can be controlled by delay of inverter used. As data path is open only for small time, power dissipation decreases. Proposed CBFF can be used for large serial data as data loading is limited to two transistors in the design. Low clock load is achieved as only two clocked transistors are used. As there is no need of refreshing circuit when data is changed, PDP is improved. Proposed flip-flop only uses static ratio insensitive differential latch (SRIS), thus achieving complementary output nodes with reduced loading. Cadence Virtuoso tool is used for simulations. In comparison to sense amplifier based flip-flop (SAFF), modified SAFF, Strollo’s flip-flop and self-blocking flip-flop (SBFF), speed and PDP is improved by more than 20 and 15% respectively.
