Agriculture University, Jodhpur

Agriculture University, Jodhpur was established on 14th September, 2013 by Government of Rajasthan under Agriculture University, Jodhpur Act 21 of 2013 to focus on holistic development of arid and semi-arid regions of the state covering 6 districts (Jodhpur, Barmer, Nagaur, Pali, Jalore and Sirohi), constituting 28% of total geographical area which is sustaining 20.8% human and 28.4% animal population of the state. The districts under jurisdiction of the university cover 3 agro-ecological zones of the state. These are Arid Western Plain Zone Ia (Jodhpur and Barmer districts), Transitional plain of Luni Basin Zone IIb (Jalore, Pali, and Sirohi districts) and part of Transitional Plain of Inland Drainage Zone IIa (Nagaur district). The university has 1 institute of diploma and 3 colleges to produce highly competent educated human resources in agriculture and allied sciences besides 2 agricultural research stations, one each in zone Ia & IIb and 3 agricultural research sub stations, one in each zone to prepare, plan and perform highly need based research in this acute water scarce but naturally rich bio-diversified zone of the country. The third most important part in tri-pillar (Teaching, Research & Extension) of agricultural development, the extension for transfer of technologies are reached to doorsteps of the farming community by 6 Krishi Vigyan Kendras (K-V-Ks), 2 in Nagaur district and 1 each in Jodhpur, Barmer, Jalore & Sirohi districts under the umbrella of the university. The different units of teaching, research and extension are coordinating to systematically run by the headquarter situated at Mandor, Jodhpur.

    Studies on Dry root rot [Macrophomina phaseolina (Tassi) Goid.] of Mothbean [Vigna aconitifolia (Jacq.) Marechal] and its Management
    (Agriculture University, Jodhpur, 2023-08-03) Jaimini, Megha; Verma, J.R.
    Mothbean [Vigna aconitifolia (Jacq). Marechal] is oldest pulses crop and affected by dry root rot diseases caused by Macrophomina phaseolina, it causes heavy yield losses during cropping season. Pathogen having a wide host range, survive in soil as saprophytic and in form of sclerotia, and management is difficult in nature, therefore it is a major problem in mothbean growing areas. The pathogen was isolated from infected root parts and purified by using hyphal tip cut technique. Proved pathogenicity through Koch’s postulates by using seed cum soil inoculation techniques and 87.64% disease incidence was observed. Out of 15 cultivars/varieties none of the variety was found immune against dry root rot. One variety RMO-2251 was found resistant, six varieties were moderately resistant, six were moderately susceptible, one was susceptible and salawas local was found highly susceptible. To study on effect of cultural media and temperature on growth of M. phaseolina found highest radial growth and excellent sclerotial formation on PDA and grew best at 30ºC temperature. Six fungicides were evaluated in vitro condition against M. phaseolina in which carbendazim 25% + mencozeb 50% was inhibited complete mycelial growth at 250, 500 and 1000 ppm concentrations. Among the organic amendments neem cake was found significantly reduced the dry root rot disease incidence and promote growth ability of mothbean crop.
