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.

    Population Dynamics of Major Insect Pests and Their Management in Isabgol (Plantago ovata Forst.)
    (Agriculture University, Jodhpur, 2022-11-05) Ola, Rajveer Singh; Kumawat, M.M.
    The investigation on “population dynamics of major insect pests and their management in isabgol (Plantago ovata Forst.)” under semi-arid condition was carried out in Rabi, 2021-22 at Instructional Farm, College of Agriculture, Jodhpur. The aphid, Aphis gossypii Glover was found the major pest of isabgol in the semi arid region of the Rajasthan. The infestation of A. gossypii was appeared on 2nd SMW and its peak activity was observed in 4th week of February (8th SMW). The activity of three coccinelids viz. Brumoides suturalis Fabricius, Cheilomenes sexmaculata Fabricius and Coccinella septempunctata Fabricius were also studied, and their peak population was of noticed from 8th to 10th SMW. C. septempunctata lead the population among coccinelids and might be played the major role in reduction of aphids. The significant positive correlation of aphids was found with bright sunshine. The correlation between the population of aphids and natural enemies was significantly positive. The significant positive correlation in population of B. suturalis, C. septempunctata and C. sexmaculata was found with bright sunshine and maximum temperature. A total of 20 genotypes of isabgol were screened against aphid, A. gossypii. The population of aphids was recorded highest at 72 DAS (12th February) which was varied from 54.51 to 40.27 aphids/plant in different genotypes, where maximum number of aphids was observed on HI 2 (54.51 aphids/plant) followed by HI 1 (54.04) and the subsequent decreasing order in aphid population was found on RI 3025 > RI 1 > RI 158 > RI 153 > RI 147 > RI 150 > RI 151 > RI 136 > GI 2 > GI 2-800-15 > RI 167 > RI 166 > RI 148 > RI 154 > RI 168 > DM 9 > RI 89- 800-4 > RI 156. The maximum reduction of aphids was recorded in treatment flonicamid 50 WG @ 75 g a.i./ha and minimum with azadirachtin 10,000 PPM. The maximum yield (1,013 kg/ha) was recorded in the treatment of flonicamid 50 WG and minimum was obtained in the untreated control (440 kg/ha) followed by azadirachtin 10,000 PPM (560 kg/ha). The highest benefit-cost ratio (2.78:1) was computed in flonicamid 50 WG and minimum B: C ratio was obtained in azadirachtin 10000 PPM (1.09:1).
