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.

    Explicating the influence of Silicon in relation to growth dynamics, biotic stress and tolerance to water deficit conditions in different genotypes of rice (Oryza sativa L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-09) Das, Sudeshna; Shankhdhar, S.C.
    Rice is one of the leading agricultural crops serving as the staple food crop for almost 50% of the existing people in the world. As the population continues to expand and climate change occurs, the escalation in food requirement is inevitable. Environmental stress (biotic and abiotic) owing to climate change alters the growth and development of plants leading to an enormous loss in crop yield and productivity. A field experiment was laid out in split-plot design replicated thrice with four treatments viz., T1: Control, T2: Si fertilized T3: Si + Drought stress and T4: Drought stress. The study was conducted during the kharif season of 2017 and 2018 to evaluate the influence of Si on growth dynamics, biotic stress and tolerance to water deficit conditions in different genotypes of rice. Various morphological, yield attributes and biochemical parameters in five genotypes namely PA-6129, US-312, KRH-4, IR-64 and Sahabhagidhan were observed. Nutrient content estimation as well as biotic stress incidence analysis was also conducted. Silicon was found to have an encouraging influence on the growth and development and yield under wellwatered as well as water-deficit conditions. Growth parameters such as plant height, tiller number, leaf number, LAI and biomass accumulation as well as yield and yield attributes such as panicle number, spikelet number, grain number, test weight and harvest index were found to enhance. Chlorophyll content, chlorophyll fluorescence, protein and amylose content together with SOD activity revealed a positive response on application of silicon. Proline and MDA content was found to decline. Upsurge in nutrient content uptake was also witnessed. KRH-4 and US-312 was recognized to deliver a commendable response to silicon fertilization under well-watered as well as water deficit conditions.

    Growth, yield and nutrient use efficiency of late sown rice under differential nutrient management
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-09) Joshi, Babita; Guru, S.K.
    The present study was undertaken to study the effect of differential nutrient management on growth, yield and nutrient use efficiency of rice genotypes under late sown condition. A field experiment was conducted during the rainy seasons of 2017 and 2018 at the Norman E. Borlaug Crop Research Centre GBPUA&T, Pantnagar, India. The experiment was laid out in a split plot design with four treatments as main plot and six rice genotypes viz. PR-113, PD-22, HKR-47, PD-24, NDR-359 and PD-19 as sub-plot and was replicated thrice under late sown condition. The treatments included 50% RDF (60:30:20 kg NPK ha-1), 100% RDF (120:60:40 kg NPK ha-1), 150% RDF (180:90:60 kg NPK ha-1) and 50%RDF+ FYM(5 t ha-1). Incremental doses of N, P and K (150%RDF) significantly improved the plant height, number of tillers, leaf growth parameters such as LAI, LAD, SLW, crop growth parameters such as CGR, RGR, NAR, leaf dry matter and shoot dry matter. Increase in CGR and RGR contributed to greater biomass production. Also the yield components such as number of panicles /m2, number of spikelets per panicle , filled grain %, increased significantly with increase in nutrient supply resulting in higher biological and grain yield. All the genotypes had increased nutrient content in plant as well as in leaf at flowering and maturity. Uptake of N, P and K by rice plant at harvest significantly increased at 150%RDF in response to nutrient supply. This ultimately resulted in increased grain yield with 150%RDF. PFP was not affected with increase in nutrient supply indicating that increasing the dose to 150%RDF increased the yield by 30-60% in all the genotypes without affecting the nutrient use efficiency at higher doses. When the dose was reduced to 50%RDF, the growth and yield parameters decreased significantly. Application of FYM along with 50% RDF could not result in yield levels comparable to 100% RDF.

    Productivity and quality assessment of Basmati rice under organic and conventional nutrient management
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-08) Joshi, Hem Chandra; Guru, S.K.
    The field experiment entitled “Productivity and Quality Assessment of Basmati Rice Under Organic and Conventional Nutrient Management” was conducted in kharif season, 2016 and 2017 at G. B. Pant University of Agriculture and Technology, Pantnagar. The experiment was laid out in split plot design with two modes of production (organic and conventional). This study involved the simultaneous characterization of soil chemical properties, agronomical parameters attributing yield, biochemical parameters, quality parameters and nutrient uptake in organic and conventional mode of production. There was no significant effect of nutrients system on soil pH in the practices, Available phosphorus, potassium, ammonical nitrogen and nitrate content were higher for conventionally managed soil. Plant height significantly affected by source of organic nutrients i.e. higher in the organically managed system. There were no effects of nutrient supply systems on the number of productive tillers; they were almost same in both the practices. However, the leaf area index was significantly affected by the nutrient supply system. During both the years the leaf area index was higher in the inorganic source of nutrient system. Moreover, dry matter production, biological yield, total yield were higher in rice plant under inorganic nutrient management system. Harvest index of organic rice was more as compared to the conventionally grown rice. Amongst grain quality parameter, hardness, true density and percent porosity were higher in rice grains under conventional nutrient supply. Inorganic rice had better milling quality but cooking quality was found better in organic rice as evident from higher elongation ratio and swelling rate. The organically grown rice was found to be tastier in comparison to inorganically grown rice as organic sample scored higher for all the parameters of sensory. The quality of protein was better in organically managed rice. Total ash, crude fiber and iron element were found higher in organically managed rice. Iron was found to be significantly higher in organic rice (1.32 mg/100 g). The nutritional analysis revealed that organic crops had higher level of nutrients.

    Biology and management of isoproturon-resistant Phalaris minor
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-01) Prinsa; Guru, S.K.
    The present study was undertaken to study the biology and management of isoproturon-resistant P. minor. For this investigation, field experiment as well as pot culture experiments were conducted during the winter season of 2016-17 and 2017-18 at the Norman E. Borlaug Crop Research Centre and Department of Plant Physiology GBPU&T Pantnagar, respectively. The field experiment was laid out in a Randomized Block Design with 10 treatments replicated thrice. The treatments included (T1) Pendimethalin, (T2) Pendimethalin+Metribuzin, (T3) Pendimethalin+Metribuzin fb Mesosulfuron + Idosulfuron (RM), (T4) Pendimethalin+Metribuzin fb Clodinafop+Metsulfuron-mehtyl (RM), (T5) Pendimethalin fb Clodinafoppropargyl, (T6) Pendimethalin fb Clodinafop+Metsulfuron-mehtyl (RM), (T7) Pendimethalin fb Mesosulfuron+Idosulfuron (RM), (T8) Clodinafop+Metsulfuron-mehtyl (RM), (T9) Mesosulfuron+Idosulfuron (RM) and (T10) Weedy. In pot culture experiment, isoproturon-resistant P. minor was grown in pots. Different pre-emergence (Pendimethalin and Metribuzin) and post emergence herbicides (Clodinafop-propargyl, Sulfosulfuron, Metribuzin, Pinoxaden and Halauxifen methyl + Pyroxsulam) at different doses were evaluated for their efficacy to control P. minor. All the herbicides, used alone or in combination significantly reduced dry matter of P. minor during both the seasons. As Phalaris minor (grass weed) creates more competitive pressure on wheat than other weeds so that their effective control by these herbicides resulted in high grain yield of wheat. In the pot culture experiment, increasing the doses of clodinafop, sulfosulfuron, pinoxaden and halauxifen methyl +pyroxsulam to 1.5X to 2.0X times their recommended doses, significantly increased their bioefficacy in controlling P. minor. A significant reduction in dry weight of P. minor was recorded in the herbicide treatments. Among the ACCase inhibitors, pinoxaden caused maximum growth reduction in Phalaris minor followed by clodinafop-propargyl. P. minor plants sprayed with metribuzin showed a very sharp decrease in Fv/Fm ratio as compared to control after 24 hours of spray even when there were no visible symptoms of herbicide injury. A significant increase was noted in the proline content of P. minor in all the herbicide treatments. MDA content was also significantly higher in all the treatments as compared to control. These indicated the stress level in P. Minor plants which indirectly prove the bioefficacy of the herbicides used in the study. It may be concluded from the present investigation that applications of alternative herbicides were found to be very effective in controlling the isoproturon-resistant P. minor. This study shows that isoproturon-resistant P. minor could be successfully controlled by using herbicides or their combination with different mechanism of action such as PSII, ACCase and ALS inhibitors. There was no adverse effect on wheat crop at recommended dose of the herbicides.
