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.

    Seasonal Incidence, Varietal Screening and Management of Major Insect Pests of Okra [Abelmoschus esculentus (L.)
    (Agriculture University, Jodhpur, 2021-08-10) Balveer; Ratnoo, S. D.; Sundria, M. M.; Shukla, U. N.
    The investigation on ‘Seasonal Incidence, Varietal Screening and Management of Major Insect Pests of Okra [Abelmoschus esculentus (L.) Moench]’ under semi-arid condition was carried out in kharif, 2020 at experimental farm, College of Agriculture, Jodhpur. The leafhopper, whitefly and mite population found to its peak in the 40th , 41th and 41th SMW, respectively. The shoot and fruit infestation found to its peak in the 43th and 45th SMW, respectively. The correlation coefficient between major insect pests and maximum temperature showed positive significant correlation with leafhopper, whitefly and mite population. While minimum temperature had positive significant correlation with the leafhoppers and negative significant correlation with fruit infestation. Relative humidity showed negative significant correlation with shoot and fruit infestation. Out of ten varieties of okra screened against major insect pests showed that PA-4, Varsha Uphar and Arka Anamika were found as least susceptible to the leaf hopper. Varieties, PA-4, Varsha Uphar and Arka Abhay were found as least susceptible to the whitefly. The all of ten varieties ranked as moderately resistance to the shoot borer infestation. The varieties PA-4, Varsha Uphar and Ankur-40 were ranked as moderately resistant to the fruit borer infestation. The varieties PA-4 and Varsha Uphar were ranked as least susceptible to the mite infestation. Out of nine insecticides imidacloprid 17.8 SL and thiamethoxam 25 WG found most effective treatment against leafhopper and whitefly. The treatments spinosad 45 SC and thiamethoxam 25 WG proved most effective against shoot and fruit borer. Spiromesifen 22.9 SC and emametin benzoate 5 SG proved most effective against mite infestation. The maximum yield of okra 78.48 q ha-1 was obtained from the plots treated with spinosad 45 SC. The highest incremental benefit-cost ratio of 1:19.14 was observed in plots treated with thiamethoxam (0.005%).
