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 and Management of Aphids in Cumin, Cuminum cyminum L.

    The investigations on “Seasonal Incidence and Management of aphids in Cumin, Cuminum cyminum Linn.” were carried out during Rabi, 2020–21 at Instructional farm, College of Agriculture, Jodhpur. The infestation of aphid population commenced in the third week of December (51st Standard Meteorological Week) which reached its peak (115.03 aphids/ 3 umbels) in fifth week of January (5th SMW) and gradually declined thereafter. The aphid population had negative non-significant correlation with the maximum temperature (r= –0.336) and minimum temperature (r= –0.465). Whereas, positive non significant correlation with relative humidity (r= 0.343). The maximum peak infestation of aphid population (106.50 aphids/ 3 umbels) was seen on late sown crop i.e. 7th December followed by 30th November (98.50 aphids/ 3 umbels) and 23rd November (96.50 aphids/ 3 umbels) crop. While, the minimum peak infestation (68.00 aphids/ 3 umbels) was recorded crop sown on 26th October followed by 2nd November (71.00 aphids/ 3 umbels), 9th November (75.00 aphids/ 3 umbels) and 16th November (83.25 aphids/ 3 umbels) sown crop. The standard check i.e., imidacloprid 17.8 SL (0.01%) proved most effective against aphid followed by entomopathogenic fungi viz., Verticillium lecanii 1.15 WP @ 5 g/l (1 x 108 CFU/g), Metarhizium anisopliae 1.15 WP @ 5 g/l (1 x 108 CFU/g) and Beauveria bassiana 1.15 WP @ 5 g/l (1 x 108 CFU/g). However, these differed significantly with standard check. Whereas, neem products viz., Azadirachtin 10,000 PPM and Azadirachtin 3,000 PPM were proved least effective against aphid. The maximum seed yield of 7.78 q/ ha was obtained in the plots treated with imidacloprid 17.8 SL. The total avoidable loss and per cent avoidable loss was found to be zero in the treatment of imidacloprid 17.8 SL which was used as standard check, whereas, maximum avoidable loss was obtained in Azadirachtin 10,000 PPM. The highest incremental cost benefit ratio of 1:16.89 was obtained in the plots treated with imidacloprid 17.8 SL followed by Verticillium lecanii 1.15 WP (1:7.18), Metarhizium anisopliae 1.15 WP (1:6.63) and Beauveria bassiana 1.15 WP (1:6.03
