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.

    Postharvest disease management of Guava caused by Colletotrichum gloeosporioides (Penz.) Penz. And Sacc.

    Guava anthracnose caused by {Colletotrichum gloeosporioides (Penz.) Penz. and Sacc.) is one of the most destructive post harvest disease in India causing huge economic losses during transit and storage at market level. In Uttarakhand, the disease showed an increasing trend in all the fruit markets from 2021 to 2022.The disease severity of anthracnose in different locations in Uttarakhand market varied from 5.20 to 26.50percent. The highest mean disease incidence ranged from 15 to 50 percent was observed in both of the year. The disease was more severe in Dehradun and least in Lalkuan (Nainital) district. Biochemical changes in guava like total soluble solids, acidity, ascorbic acid, sugars, total flavonoids content, phenolic content, antioxidants were recorded under each treatment overa storage period of 12 days. Chitosan (1.5%), calcium chloride (1.50% and 2.50%) and Aloe veral: l gel treatment was most effective in maintaining shelf life, enhancing biochemical quality and in reducing postharvest losses in guava fruits. Among the post harvest dip treatment of fungicides, Tebuconazole + Trifloxystrobin at 0.15 per cent concentration was found most effective in respect of checking the anthracnose severity development in treated fruits of guava cv. L- 49.Antagonistsevaluations revealed that the Trichoderma +Pseudomonas fiuorescens at 15 g/1 concentration was found promising against the pathogen in reducing severity (79.70%) in guava. In addition the activity of inorganic salts, Calcium chloride at 2.50percentwas found highly effective in reducing disease severity (72.24%) over check. Among the plant extracts Aloe vera (1:3) was found to be the best in checking the severity of anthracnose providing (56.13%) reduction over check. Zinc oxide (0.50%) was found to be more effective among all the nano particles in reducing the disease severity. Hot water treatment at 57°C was found effective than UV irradiation showing least disease severity. Among the elicitors Salicylic acid at 2mM concentration was found to be most effective in reducing disease severity in cv. L-49 during storage. Our results suggested that susceptibility of guava cv. L-49 to anthracnose during storage is dependent on the high temperature which favours the attack of fungal pathogens causing post harvest anthracnose. Further our results indicate that effective management strategy helps in reduction of anthracnose disease as well as maintains quality of fruit.
