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.

ThesisItem Open Access Population Dynamics of Insect Pests and Management of Aphid, Lipaphis erysimi (Kalt.) in Mustard(Agriculture University, Jodhpur, 2022-07-25) PRATIHAR, AKSHAY KUMAR SINGH; Sundria, M. M.; Pandey, Shalini; Bhardwaj, RahulThe investigation on “Population Dynamics of Insect Pests and Management of Aphid, Lipaphis erysimi (Kalt.) in Mustard” under semi-arid condition was carried out in Rabi, 2021-22 at Research Farm of Agricultural Research Station, Mandor, Jodhpur. The aphid infestation was initiated from 51st SMW and the peak activity (126.20 aphid/10 cm terminal shoot) on 4th SMW. After that progressive decline was observed. The painted bug infestation was observed two times, where it was initiated early on 45th SMW and no infestation during from 2nd SMW to 7th SMW. Its infestation was occurred again at 8th SMW and reached to peak level (5.13 bugs/plant) at 10th SMW. The flea beetle infestation was initiated from 1st SMW and continued till 8th SMW. Peak activity on 4th SMW (0.93 beetles/plant) and then gradually declined. The leaf webber infestation was initiated from 48th SMW and reached to peak activity (2.87 larvae/plant) on 6th SMW. Natural enemy i.e., Coccinella septempunctata appeared in 1st SMW and peak activity was noticed on 8th SMW. Mustard aphid, flea beetle and leaf webber were significantly negative correlated with minimum temp. While, ladybird beetle was significantly positive with minimum temp. and sunshine, also. Painted bug and ladybird beetle both were significantly positive with maximum temp. and average temperature whereas, aphid had significantly negative with average temperature. Morning RH correlated significant positive with aphid. While, significant negative relation of ladybird beetle with morning and avg. RH. Painted bug was significant negative correlation with evening RH and avg. temperature. There was no significant relation with rainfall. Ten genotypes/varieties of Indian mustard (Brassica juncea) were screened against mustard aphid, the results revealed that TM 108-1, Kranti and Bio 902 were found as resistant, TM 267-3, TM 316, TM 304-1, RH 749, PM 31 and GDM 4 were identified as the moderately resistant while LS-FF-57 was found as tolerant.Ten genotypes/varieties of Yellow sarson (Brassica rapa) were screened against mustard aphid, the results revealed that MYS-152, YSH-401 and NRCYS 05- 02 were found as resistant, RMYS-1, RMYS-2, RMYS-3, MYS-180, MYS-183, Jhumka and Pitambari were identified as moderately resistant. Ten genotypes/varieties of five different Brassica species were screened against mustard aphid, the results revealed that none of the genotypes/varieties were found as resistant. Tapeshwari, Bhawani, Pusa Swarna, Pusa Aaditya, MBT-27, MBT-4 and GP 115-1 were identified as the moderately resistant whereas, varieties MN-1, Karantara and RTM-1351 were found as tolerant. The treatment of imidacloprid 17.8 SL was found most effective followed by thiamethoxam 25 WG and dimethoate 30 EC while, treatments of diafenthiuron 50 WP and chlorpyriphos 20 EC as least effective. The maximum yield of 3861 kg/ha was recorded in the plot treated with imidacloprid 17.8 SL followed by thiamethoxam 25 WG (3444 kg/ha) and dimethoate 30 EC (3194 kg/ha). Maximum net profit of Rs. 2,00,290 ha-1 was obtained from imidacloprid 17.8 SL. The highest B: C ratio of computed in imidacloprid 17.8 SL (6.38:1) followed by 5.60:1 in thiamethoxam 25 WG and 4.99:1 in dimethoate 30 EC while, minimum (2.71:1) was obtained in chlorpyriphos 20 EC.ThesisItem Open Access Biology and Management of Leaf Webber and Capsule Borer, Antigastra catalaunalis (Duponchel) in Sesame(Agriculture University, Jodhpur, 2021-08-17) Kumar, Santosh; Sundria, M. M.; Kumawat, M. M.; Ram, DamaThe biology of leaf webber and capsule borer, Antigastra catalaunalis was studied on sesame variety RT-351 under laboratory conditions and found that the female moth laid their eggs singly, oval in shape, translucent with orange colour spots with length and width varied from 0.35 - 0.45 mm and 0.18 - 0.25 mm, respectively. Incubation period found varied from 50.00 to 70.00 hours. There were five larval instars and total larval period varied from 9.28 to 12.60 days and the pupal period lasted from 4.20 to 7.40 days. The average length and width of pupa was found 7.43 ± 0.47 and 1.43 ± 0.22 mm. Moths were stout and medium in size. The colour of moth varied from light reddish brown to dark reddish brown. The female moth lived slightly longer than the males. Average male to female ratio was showed 1.0:1.1 to 1.0:1.3. During screening of sesame genotypes against sesame leaf webber and capsule borer, Antigastra catalaunalis (Duponchel) recorded 8.83% to 26.22%, 8.73% to 23.52% and 4.82% to 12.50% damage at vegetative, flowering and capsule stages, respectively. Genotype EC-35000 was found resistant and genotypes viz., NIC 13362A, IS-346, IS-552, SI-3275, IS-199-2-04 and SI-3315-16 were found moderately resistant whereas genotypes viz., SI-1925, S-0627 and IC-152485 were found moderately susceptible. Strain II of Beauveria bassiana gave 100, 95.00, 90.00, 77.50 and 70.00per cent of mortality against 1st, 2nd, 3rd, 4th and 5th instar larvae after 96 hours of treatment, respectively, whereas bacterium, Bacillus thuringiensis var. kurstaki (Bt) gave 50.00, 45.00, 42.50, 32.50 and 20.00 per cent mortality of 1st, 2nd, 3rd, 4th and 5th instar larvae after 96 hours of application, respectively, under laboratory conditions among all the entomophagous fungal pathogen. Based on overall results, efficacy of bio-agents against A. catalaunalis can be showed in order B. bassiana strain II>B. bassiana strain I>M. anisopliae>V. dahlia>I. fumosorosea>Bacillus thuringiensis.ThesisItem Open Access Seasonal Incidence and Management of Aphids in Cumin, Cuminum cyminum L.(Agriculture University, Jodhpur, 2021-10-08) Choudhary, Nisha; Kumawat, M. M.; Sundria, M. M.; Moond, S. K.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 (1:6.03ThesisItem Open Access Seasonal Incidence and Management of Insect Pest of Mungbean [Vigna radiata (L.)

N.ThesisItem Open Access 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%).
