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.

    Role of weather parameters on potato late blight disease caused by Phytophthora infestans (Mont) de Bary and its chemical management

    Potato (Solanum tuberosum) belonging to the family Solanaceae is one of the important crops in terms of human consumption. Nutritionally, it is second important crop after soybean for protein/ha and is considered a non-fattening, nutritious and wholesome food. It is a crop that can be grown as both rabi as well as kharif season providing more revenue to the farmers. Besides playing a significant role in the cropping system worldwide, potato crop suffers from huge losses due to bio stresses which can be biotic or abiotic. Late blight of potato is one of them and is caused by Phytophthora infestans which appear as water-soaked pale green lesions near the tip and margin of leaves. On the lower side of leaves white fungal growth appears and later infection spread toward the stem and other parts of the plant. Tubers are also infected with late blight pathogen and become firm, dry, brown and prone to rotting by bacteria. A loss of 100% can be seen within a week if the environment is favorable for pathogens. The field experiments were conducted at VRC, Pantnagar during 2021-22 cropping season. The present study focuses on the effect of prevailing environmental conditions on potato crops. The potato crop was sown at three different dates of planting to study late blight severity and its correlation with weather parameters. Similarly, nine potato varieties were screened out not only for late blight resistance but also to study the effect of weather parameters in each potato variety. Field experiment on fungicide scheduling, one resistant (Kufri Khyati) and one susceptible (Kufri Bahar) variety of potato were selected to study the effectiveness of different fungicidal combinations against late blight disease. Further, efficacy of different new fungicides was also tested against late blight of potato and compared to farmer’s practice in terms of cost-benefit ratio. Results obtained from experiments showed that less blight severity was in late sown crop as compared to timely and early sown crop. Correlation analysis revealed that maximum temperature was negative correlated with disease index while, minimum relative humidity was significant and positively correlated. Rainfall was also found to play a significant role in disease progression. In an experiment of screening of nine different potato cultivars, Kufri Chipsona- 3, Kufri Sadabahar and Kufri Surya were found resistant with the minimum effect of weather parameter against late blight disease. In an experiment on fungicide scheduling for late blight disease management, treatment consisting of ametoctradin + dimethomorph @ 0.2% was found effective in both Kufri Bahar and Kufri Khyati. But better results were obtained for potato cultivar Kufri Khyati as it is more resistant to late blight under field conditions. Among all the new tested fungicides, treatment of oxathiapiprolin 10.1% OD @ 200ml/ha was found the most effective followed by amisulbrom 20% SC @ 500ml/ha and picoxystrobin 25% SC @ 500 ml/ha and these treatments gave more cost- benefit ratio as compared to farmer’s conventional practice.
