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.

    Biocontrol of banded leaf & sheath blight of maize caused by Rhizoctonia solani f.sp. sasakii using Pseudomonas strains AS19 & AS21
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-02) Kabdwal, Manisha; Sahgal, Manvika
    Maize is the third most important cereal crop which provides food and nutritional security in the country. Banded leaf and sheath blight (BL &SB) caused by Rhizoctonia solani f.sp.sasakii is responsible for 10 to 40% yield loss in maize. Considering the harmful effects of chemical pesticides on human health and environment, biological control gains importance. The present study was undertaken to evaluate the field efficacy of two Pseudomonas strains AS19 (Culture Accession No. NAIMCC-B-02303) and AS21 (Culture Accession No. NAIMCC-B-02304) against Rhizoctonia solani f.sp.sasakii causing BL&SB in maize. The cell-free supernatant and whole-cell culture of both the strains inhibited fungal mycelium significantly under in vitro conditions. The percent mycelial inhibition with cell-free supernatant of AS19 (58.03%) and AS21 (62.56%) was higher than whole-cell culture of AS19 (48.43%) and AS21 (52.2%). Both Pseudomonas strains (AS19 and AS21) were positive for hydrolytic enzyme production (chitinase, β1-3 glucanase, protease, amylase, and gelatinase) and plant growth promoting traits (siderophore, ammonia, IAA, HCN, and phosphate solubilization). Subsequently, these two Pseudomonas strains were selected for field trial to evaluate their in vivo biocontrol potential and elucidate mechanism of control. The significant effect on disease control and plant growth were observed for field inoculated with AS21 with 29.19 % disease control and 17.76 % reduction in avoidable yield loss. A separate trial was conducted to elucidate the biocontrol mechanism, the seed plus soil formulation of BCAs resulted in higher disease reduction and enhanced growth. Inoculation of Pseudomonas strains resulted in enhanced level of defense responses like total phenol, protein content and reactive oxygen species(ROS) enzymes (superoxide dismutase, catalase, phenylalanine ammonia-lyase, peroxidase and polyphenol oxidase). Overall from above results, it is concluded that inoculation of bacterial biocontrol agent (BCAs) induced plant immunity against R.solani f.sp. sasakii and showed induced systemic resistance (ISR) as a mechanism of disease control. Therefore, the two antagonistic Pseudomonas species can be exploited as a commercial biocontrol agent against banded leaf and sheath blight disease in maize.
