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.

    Effect of Seed Priming, Plant Bioregulators and Boron on Qualitative and Quantitative Performance of Bottle Gourd [Lagenaria siceraria (Mol.) Standl.]
    (Agriculture University, Jodhpur, 2024-04-06) Anupama; Moond, S.K.
    The present experiment entitled “Effect of seed priming, plant bioregulators and boron on qualitative and quantitative performance of Bottle gourd [Lagenaria siceraria (Mol.) Standl.]” was conducted under Randomized Block Design (RBD) with three replications using cultivar Pusa Naveen at the Instructional Farm and Laboratory of the Department of Horticulture, College of Agriculture, Jodhpur during summer seasons of 2020 and 2021. The research was conducted into two sub experiments. In the first experiment, the seeds of bottle gourd cultivar Pusa Naveen were primed with 7 different priming agents with 2 different soaking periods (12 and 24 hours) keeping unprimed seeds as control which consisted fifteen treatments i.e. Osmopriming with PEG 6000 @ -0.5 MPa for 12 and 24 hrs, Harmonal priming with GA3 @ 100 ppm for 12 and 24 hrs, Halopriming with Na2HPO4 @ 1% for 12 and 24 hrs, KH2PO4 @ 1% for 12 and 24 hrs, KNO3 @ 2% for 12 and 24 hrs and CaCl2 @ 2% for 12 and 24 hrs and Hydropriming with distilled water for 12 and 24 hrs and a control (untreated). It was found that seeds primed with GA3 @100 ppm for 24 hrs (T11) exhibited best results in terms of germination percentage (95.86%), speed of germination (7.25 days), field emergence (86.68%), speed of field emergence (5.22 days), seedling root length (12.04 cm), shoot length (19.74 cm), seedling length (31.78 cm), seedling dry weight (1.17 g), vigour index-I (2755) and vigour index- II (101.87) which was closely followed by PEG 6000 @-0.5MPa for 24hrs (T10) on the basis of pooled analysis. In the field study parameters, treatment of seeds with GA3 @100 ppm for 24 hrs proved to be the best treatment for characters like days to first female flower anthesis (57.46 days), 50 per cent flowering (58.23 days), vine length (5.56 m), number of primary branches (9.87), days to first picking (69.58 days), number of fruits per vine (8.63), fruit length (27.29 cm), fruit diameter (6.67 cm), fruit weight (682 g) and fruit yield per vine (6.07 kg/ha) and yield per ha (270.29 q) with maximum net returns (Rs.1,96,053) and B:C ratio (3.64). Amongst the various seed priming treatments, Bottle gourd seeds were primed with GA3 @100 ppm for 24 hours was rated as the most cost-effective treatment which produced the maximum fruit yield per hectare, net returns and B:C ratio. The second experiment consisted 21 treatment combinations i.e three plant bioregulators (Ethrel, NAA and GA3) with two different concentration and two levels of boron applied at 2 to 4 true leaf stage and 30 days after first spray during both the years. The results showed that borax 0.05% + ethrel 500 ppm (T11) significantly increased the plant growth, yield and quality parameters as compared to control treatment. On the basis of pooled analysis, the longest vine length (5.83 m) was recorded with the treatment borax 0.05% + GA3 50 ppm. The minimum number of days to first male flower anthesis (43.83 days), minimum days to first female flower anthesis (45.40 days), minimum days to 50 per cent flowering (46.05 days), minimum days to first picking (58.37 days), lowest number of node on which first female flower appeared (14.04), highest number of primary branches per vine (11.73), highest number of nodes on main vine (54.86), maximum number of fruits per vine (9.07), maximum fruit yield per vine (6.43 kg) and per hectare (286.15q/ha), maximum TSS (3.47 ᵒBrix) and ascorbic acid content (7.59 mg/100g) were recorded with borax 0.05% + ethrel 500 ppm (T11) which was statistically at par with the treatments borax 0.05% + NAA 100 ppm and borax 0.05% + NAA 200 ppm on pooled basis. The longest fruit (27.88 cm) with maximum diameter (6.95 cm) and the heaviest fruit weight (720 g) were recorded under the treatment borax @ 0.05% + NAA 200 ppm (T15) on pooled basis. Based on economics, borax @ 0.05% + ethrel 500 ppm was found to be more profitable in terms of net returns (Rs. 2,16,451 per ha) with highest B:C ratio (4.11) followed by foliar spray of NAA @100 and 200 ppm with borax @ 0.05%. On the basis of experimental findings, it is concluded that bottle gourd cv. Pusa Naveen sprayed with borax 0.05% + ethrel 500 ppm (T11) at 2 to 4 true leaf stage and 30 days after first spray provided the maximum income with a cost benefit ratio.
