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.

    Efficacy of Subhash Palekar’s natural formulations against insect pest complex of pigeonpea at Pantnagar, Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2020-12) Mahankuda, Bhabani; Tiwari, Ruchira
    or : Dr. Ruchira Tiwari The present study was carried out to validate the efficacy of four Subhash Palekar’s Natural Formulations (SPNF) namely agniastra, neemastra, dashparni and jivamrit along with panchagavya @3%, desi cow urine and buffalo urine @20% against insect pest complex of pigeonpea under field conditions at NEBCRC, Pantnagar, Uttarakhand during kharif crop seasons 2018-19 and 2019-20. Field experiments were also carried out to study the diversity, succession and population dynamics of different insect pests and natural enemies on pigeonpea along with their correlation with different weather parameters. Whereas, laboratory experiments were also carried out at Department of Entomology, GBPUAT, Pantnagar to study the biology, effect of natural formulations on feeding preference (orientation), feeding inhibition (antifeedant activity) and growth and development of spotted pod borer (Maruca vitrata) and pod bug (Clavigralla gibbosa) on pigeonpea. A total number of twenty-four insects attacking to the pigeonpea crop and their associated nine natural enemies were reported during the study. A constant association of insect pests with the crop was observed, starting from the vegetative stage to maturity. On the basis of abundance and population dynamics of different insect pest; jassids (5.18/plant), leaf folder (11.10/plant) and leaf webber (2.57/plant) can be considered as minor pests during the vegetative crop, as they didn’t cause any significant damage to the crop. Whereas, with the onset of flowering, attack of spotted pod borer (24.7/plant), pod bug (14.8/plant) and gram pod borer (7.13/plant) were reported on the crop. These three pests can be categorized as major pests during the reproductive stage causing significant damage to the economic parts of the crop and contributing to yield loss. A total number of three sprays were carried out during the field experiment to study the efficacy of different natural formulations against spotted pod borer, pod bug and gram pod borer. The order of efficacy remained the same as Chlorantraniliprole followed by agniastra, neemastra, dashparni, desi cow urine, panchagavya, buffalo urine and jivamrit for spotted pod borer and gram pod borer during both the kharif crop seasons 2018-19 and 2019-20. However, dashparni was found most effective for pod bug amongst all the natural formulations. Agniastra was found most effective amongst the natural formulations with 6.09 maruca webs/plant. The pooled mean population of pod bugs varied from 1.65-5.67 bugs/plant with minimum and maximum population in chlorantraniliprole and untreated control plots, respectively. Whereas, dashparni was found the best among the natural formulation with 1.81 bugs/plant. Similarly, Chlorantraniliprole was found most effective against Helicoverpa larvae followed by agniastra with 1.65 and 1.75larvae/plant, respectively as compared to 5.05 larvae/plant in plots of untreated pigeonpea crop. These natural formulations didn’t have any significant adverse effects against the natural enemies. Similarly, all the natural formulations were found effective against spotted pod borer and pod bug under the laboratory experiment. However, among SPNF, agniastra was found most effective against spotted pod borer and dashparni against pod bug during all the laboratory experiments. Amongst the treatments, agniastra reported least number of insect orientation (0.08) and low preference index (0.33) with no healthy adult emergence of spotted pod borer. Whereas, dashparni reported the least number of insect orientation (0.08) and low growth index value (1.36) against pod bug. The results obtained through present experiments clearly revealed the efficacy of Subhash Palekar’s natural formulations against different insect pest of pigeonpea. Thus, it can be concluded that in order to reduce the hazards of chemical farming, Subhash Palekar’s natural formulations can safely be incorporated in different IPM modules of pigeonpea for sustainable insect pest management.
