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.

    Exploration of Cumin (Cuminum cyminum L.) wilt (Fusarium oxysporum f.sp. cumini) and it’s Management
    (Agriculture University, Jodhpur, 2021-08-08) Jangir, Hitendra; Ram, Dama; Verma, J.R.; Singh, L.N.
    Cumin (Cuminum cyminum L.) belongs to the family Apiaceae, locally known as Jeera or Zeera. It is believed to be a native of the Mediterranean and Near Eastern regions. It is mainly cultivated in India, Egypt, Libya, Iran, Pakistan and Mexico. For the better cultivation moderate sub-tropical climate is appropriate and required cool and dry climate for better growth. It cannot withstand high humidity and heavy rainfall. For cumin cultivation well drained sandy or loamy soil is preferred and mostly grown on light textured soil deficient in nitrogen with low water retention capacity. Seed and soil borne pathogens are the major constraints in production of cumin, causing poor germination and early mortality of seedling. Cumin crop is mainly affected by three fungal (wilt, blight & powdery mildew) diseases. Wilt caused by Fusarium oxysporum f.sp. cumini is one of the most important disease. Cumin wilt disease usually seen during early stages of crop growth to crop harvesting stage resulting in damage to the seed. The annual yield losses due to wilt disease alone are up to 60%, the disease has a potential to damage the crop with up to 25.7% but may be 60% losses in some cases, and the detailed investigations on various aspects were carried out in the present study. A roving survey carried out for wilt disease incidence in different tehsils of Jodhpur district of Rajasthan showed that Tinwari recorded maximum wilt disease incidence (21.92%) followed by Balesar (19.10%), Phalodi (17.17%), Osian (15.55%) and minimum wilt disease incidence was recorded in Bilara (12.87%). The freshly infected cumin plants showed typical wilt symptoms were collected from the farmer’s field and isolate by following standard tissue isolation method and revealed the association of Fusarium oxysporum f.sp. cumini after studying the cultural and morphological characters of the fungus and the pathogenicity was proved by following Koch’s Postulates. The pure culture was sent for identification to Indian Type Culture Collection (I.T.C.C.), I.A.R.I., New Delhi – 110 012 and was identified as Fusarium oxysporum f.sp. cumini (ID. No. 11,536.21). Thirty cumin germplasm were screened, none of the germplasm showed immune and resistant reaction under field condition.
