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.

    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.
