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.

    Efficient removal of crystal violet dye from industrial wastewater using Fe3+ coated biochar
    (G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar, Uttarakhand. PIN - 263145, 2022-08) Joshi, Manisha; Srivastava, Anjana
    Crystal violet (CV), a cationic triarylmethane group is one of the most commonly used synthetic dye for purple coloration in aqueous solutions. CV is used in the production of black and blue inks for ballpoint pens, printer ink jet manufacturing industries etc. CV, like most dyes, is toxic and carcinogenic with an obstinate classification. In this research study, we used Fetreated PNB for the removal of CV dye from industrial wastewater. The effects of concentration, pH, ionic strength, temperature on adsorption–desorption behavior of this dye were seen. Ion exchange studies were also performed using CH3COOH. The results suggested that the equilibration time of adsorption of CV dye onto Fe-treated and untreated biochar was 24 hours both at pH 7.0 and 9.2, with maximum dye adsorption at pH 7.0. Pseudo-first order kinetics fit well to the adsorption kinetics of CV dye onto untreated and Fe-treated biochar, with R2 values of 0.959 for Fe-treated biochar at pH 9.2 and 0.995 for untreated biochar at pH 7.0; all significant at p ≤0.001 and the lowest SEest value. At both pH levels, the quantity of CV dye adsorbed increased with increasing initial concentration for Fe-treated and untreated biochar. The adsorption data of CV onto untreated and Fe-treated biochar at equllibrium pH 7.0 and untreated biochar at pH 9.2 fit well to the to the Freundlich adsorption isotherm (R2= 0.877, significant at p ≤ 0.05 to 0.946, significant at p ≤ 0.01). However, the R2 value for Fe-treated biochar at equilibrium pH 9.2 was 0.746, which was statistically insignificant at p≤ 0.05. Third degree polynomial connections adequately described desorption data (R2= 0.987 to 0.998, all significant at p ≤ 0.01). The adsorption of CV dye onto treated and untreated biochars was significantly increased by increasing the ionic strength from 0.003 to 0.03 and decreased on increasing ionic strength from 0.03 to 0.3. The rise in temperature above 35 ˚C for untreated biochar at pH 7.0 and beyond 25 ˚C at pH 9.2 was statistically insignificant. Similarly, the amount of the relative increase in CV adsorption with temperature increase from 5 to 15 ˚C and from 25 to 45 ˚C for Fe-treated biochar at pH 7.0 was not statistically significant. At pH 9.2, the relative increase in CV adsorption by Fe-treated biochar with temperature rise from 5 to 15 ˚C was statistically insignificant. FTIR spectra revealed the presence of –OH and >C=O on the surface of untreated biochar, as well as certain oxyhydroxide minerals of Fe in Fe-treated biochars. Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) analysis revealed the heterogeneous and porous structure of untreated biochar. Fe was seen to accumulate as polymerized hydroxy species in Fe-treated biochar. At pH 7.0, a substantial dye deposit was seen in dye-loaded treated biochar. There was some disintegration of untreated biochar surface and separation of Fe hydroxy compounds from treated biochar at pH 9.2. EDS approach was used to determine the percentage of each element in various biochars. Untreated biochars had substantial concentrations of C, O, Mg, K, and Ca, whereas Fe-treated biochars contained considerable amounts of Fe, Ag, Si, and trace amounts of Ca.

    Evaluation of microbial consortia on paddy grown under organic, inorganic and integrated production system
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-01) Joshi, Manisha; Singh, Ajay Veer
    The farmers and researchers are trying various combination of organic as well as inorganic fertilizers in agriculture to gain maximum produce without damage of soil health to fulfill the food demands of surging population across the globe. Plant growth promoting rhizobacteria (PGPRs) play an important role in sustainable agriculture through the improvement of plant growth via different processes like biological nitrogen fixation, phosphate solubilization, potassium solubilization, zinc solubilization, siderophore production and phytohormone synthesis. The use of PGPR is potentially increased in sustainable farming due to its eco-friendly and efficient nature. The present study is accomplished with implementation of potential plant growth promoting rhizobacteria (PGPRs) in different production systems i.e., organic, inorganic and integrated production system to compare and screen out the best combination for maximum yield. For this study, four bacterial isolates were retrieved from departmental culture collection and tested for various biochemical tests including carbohydrate utilization for various sources and antibiotic sensitivity assay. All the selected bacterial isolates were utilized for preparation of consortia on the basis of biocompatibility assay. Afterwards, bacterial isolates and their two consortia (C1 & C2) were tested for PGP traits like IAA production, phosphate solubilization, zinc solubilization, siderophore production, potassium solubilization, nitrogen fixation etc. On the basis of plant growth promoting traits analysis, consortium 1(SRK 14, MRC II 6) was selected for field experiment. The consortia 1 treated paddy seedlings were evaluated for growth and yield under different treatments of organic, inorganic and integrated production system. The results of the present study showed that treatment of microbial consortium (C1) was able to enhance the total chlorophyll content, carotenoid content, plant height, number of tillers, root length, root volume, panicle length, grain weight per panicle, thousand grain weight, effective tillers/m2, grain yield and total biological yield in all treatments. However, the maximum results for all parameters were recorded in treatment 6 (T6) under integrated I production system having combination of 50% organic fertilizers + 50% inorganic fertilizers + microbial consortia. Along with integrated production system, the use of consortium (C1) gave maximum results in organic as well as inorganic production systems indicating its promising potential. Hence, developed microbial consortia can be used as plant growth promoting biofertilizer to enhance plant growth and yield of paddy under field system in sustainable manner.
