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.

    Performance of Gladiolus (Gladiolus hybridus Hort.) Genotypes under Arid Conditions of Rajasthan
    (Agriculture University, Jodhpur, 2023-08-19) Choudhary, Rajneesh; Moond, S.K.
    A field experiment was conducted on 10 genotypes of gladiolus (‘Suchitra’, ‘Gunjan’, ‘Jyotsna’,‘White Prosperity’, ‘Chandni’, ‘Pusa Shanti’, ‘Creamy Green’, ‘Rani’, ‘Green Spire’ and ‘Punjab Dawn’) in a Randomized Block Design with three replications, at the Instructional Farm, College of Agriculture, Jodhpur, during the Rabi season (November to April) of 2022-23, to study performance and expression of genetic variability of gladiolus genotypes under Jodhpur (Rajasthan) conditions. The performance of genotypes depicted that ‘White Prosperity’ were recorded tallest plants (107.33 cm), longest spikes (86.00 cm), maximum number of leaves per plant (10.30), leaf width (4.13 cm), leaf length (50.10 cm), spike diameter (0.87 cm), rachis length (66.00 cm), number of florets per spike (16.17), floret diameter (8.23 cm), number of cormels produced per plant (40.00), weight of cormels per plant (27.77 g) and vase life of spike (8.74 days). The genotype ‘Punjab Dawn’ yielded the highest number of spikes per plant (2.40) and higher spike yield of (157.57 thousand per hectare) amongst all the genotypes. The genotype ‘Chandni’ required the minimum days to spike emergence (59.41 days) and the minimum days to first floret opening from spike emergence (8.53 days). The genotype ‘Gunjan’ had the highest yield of corms per plant (2.94) and estimated corm yield per hectare (169.696 thousands) as well as maximum diameter of corm (4.71 cm) & weight of corm (59.00 g). Genetic variability among the genotypes was estimated in terms of range, GCV and PCV, and correlation among the 20 parameters of study was analysed. The number and weight of cormels produced per plant recorded high order estimates for GCV indicating that these characters were governed by the additive gene effects and hence, selection could be effective for their improvement. Analysis of variance exhibited significant differences for all the characters. Analyses of correlation, genotypic correlation was higher corresponding to phenotypic correlation for most of the parameters.
