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.

    Genetic Variability and Stability Analysis in Mustard (Brassica juncea L.)
    (Agriculture University, Jodhpur, 2022-09-29) Kumar, Surendra; Bhardwaj, Rahul
    An experiment entitled “Genetic Variability and Stability Analysis in Mustard (Brassica juncea L.)” was conducted with forty-five genotypes over four different environments created by two date of sowing and two different spacing between row to row in Rabi 2021-22 at Instructional Farm, Collage of Agriculture, Jodhpur. The experiment was laid out in RBD with two replications and observations were recorded for days to 50 per cent flowering, days to maturity, plant height, first branch initiation height, number of primary branches per plant, siliqua density of main raceme, number of siliquae per plant, silique length, number of seeds per siliqua, 1000-seed weight, seed yield per plant, seed yield (kg/ha), harvest index and oil content. Pooled analysis of variance revealed significant differences due to genotype, environment and G × E for all the traits under study. Environment wise analysis of variance revealed that significant differences were observed for genotypes in all four environments for all the traits. Timely sown and normal spacing environment (E1) was better for the expression of traits as it was having wider range from most of the traits and timely sown and reduced spacing environment (E2) was relatively better as it having higher mean for yield and most of the yield contributing traits. The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the traits which inferred influence of environment. Highest value of PCV and GCV were observed for number of siliquae per plant, seed yield per plant, seed yield (kg/ha) in all the four environments. High heritability along with high genetic advance as per cent of mean were observed for number of siliquae per plant, seed yield per plant, seed yield (kg/ha), first branch initiation height, plant height, number of primary branches per plant, 1000-seed weight and number of seeds per siliqua for all the four environments suggested that these traits were governed by additive gene action. Hence, these traits are much likely to prove effective in selection to improve seed yield per plant in mustard. E + (G×E) was also significant for all the traits except first branch initiation height, number of primary branches per plant, number of seeds per silique and harvest index. The stability analysis following Eberhart and Russell (1966) model revealed that two genotypes TM 303-2 and TM 312-2 showed average stability for seed yield per plant. Whereas the genotypes TM 314-1, TM 314-2, TM 317-1, JD 6, GDM 4, Navgold, Bio-902, Kranti, and RH 0749 were stable and desirable for seed yield (kg/ha) because these had high mean, regression coefficient equivalent to unity (bi=1) and S2 di were non-significant/zero. Thus, these genotypes are desirable over wide range of environment conditions. These genotypes can be used in hybridization programme as a parent as may through advantageous sergeants for respective environment in upcoming generations.

    Efficacy of Herbicides on Growth and Yield of Pearl millet [Pennisetum glaucum (L.) R. Br.]
    (Agriculture University, Jodhpur, 2020-11-02) Kumar, Surendra; Choudhary, Rakesh; Singh, Ishwar; Mehriya, M.L.
    A field experiment was conducted at Instructional Farm, College of Agriculture, Jodhpur during kharif, 2019 to study the “Efficacy of herbicides on growth and yield of pearl millet [Pennisetum glaucum (L.) R. Br.]”. The experiment was laid out in randomized block design wherein, thirteen treatments were undertaken and replicated thrice. The treatments taken in the investigation were T1- Tembotrione 42% SC @ 90 g a.i. ha-1 at 20 DAS, T2- Tembotrione 42% SC @ 100 g a.i. ha-1 at 20 DAS, T3- Tembotrione 42% SC @ 110 g a.i. ha-1 at 20 DAS, T4- Tembotrione 42% SC @ 120 g a.i. ha-1 at 20 DAS, T5- Tembotrione 42% SC @ 90 g a.i. ha-1 at 25 DAS, T6- Tembotrione 42% SC @ 100 g a.i. ha-1 at 25 DAS, T7- Tembotrione 42% SC @ 110 g a.i. ha-1 at 25 DAS, T8- Tembotrione 42% SC @ 120 g a.i. ha-1 at 25 DAS, T9- Atrazine 50% WP @ 400 g a.i. ha-1 (PE) fb Tembotrione 42% SC @ 90 g a.i. ha-1 at 25 DAS, T10- Atrazine 50% WP @ 400 g a.i. ha-1 at 20 DAS fb one hand weeding at 35 DAS, T11- Atrazine 50% WP @ 500 g a.i. ha-1 (PE) fb one hand weeding at 30 DAS, T12- Weedy check and T13- Weed free. Among weed management treatments, atrazine 50% WP @ 400 g a.i. ha-1 (PE) fb tembotrione 42% SC @ 90 g a.i. ha-1 at 25 DAS showed the lowest weed density (3.96 m-2) and weed dry weight (1.79 g m-2) at 20 DAS. But lower weed density of total weeds (broad and narrow leaved) at 40 DAS and at harvest stage were found in atrazine 50% WP @ 400 g a.i. ha-1 at 20 DAS fb one hand weeding at 35 DAS (2.40 m -2 & 2.50 m-2). The lowest dry matter at 40 DAS (1.76 g m-2) and harvest stage (2.56 g m-2) were found in atrazine 50% WP @ 400 g a.i. ha-1 at 20 DAS fb one hand weeding at 35 DAS and atrazine 50% WP @ 500 g a.i. ha-1 (PE) fb one hand weeding at 30 DAS over weedy check, respectively. The higher weed control efficiency was recorded by application of pre and post emergence herbicides i.e. atrazine 50% WP @ 400 g a.i. ha-1 (PE) fb tembotrione 42% SC @ 90 g a.i. ha-1 at 25 DAS (80.94%) at 20 DAS. At 40 DAS atrazine 50% WP @ 400 g a.i. ha-1 at 20 DAS fb one hand weeding at 35 DAS was found superior with weed control efficiency of 96.52% but application of pre-emergence atrazine 50% WP @ 500 g a.i. ha-1 (PE) fb one hand weeding at 30 DAS showed maximum control efficiency (95.04%) at harvest stage. The lowest weed index was found with atrazine 50% WP @ 500 g a.i. ha-1 (PE) fb one hand weeding at 30 DAS (7.93%). The significant taller plant and plant dry matter at all crop growth stages (74.9 cm & 179.6 cm) and (77.7 g m -2 & 672.1 g m-2) were recorded with the application of atrazine 50% WP @ 500 g a.i. ha-1 (PE) fb one hand weeding at 30 DAS. The maximum value of yield attributes viz. effective tillers (2.67 plant-1), test weight (8.29 g), girth (31.43 mm), ear head length (28.53 cm), grain yield (2194 kg ha-1), stover yield (4527 kg ha-1), and biological yield (6721 kg ha-1)were observed with the treatment atrazine 50% WP @ 500 g a.i. ha-1 (PE) fb one hand weeding at 30 DAS. Economic evaluation of treatment weed free fetched highest gross return (` 81681 ha-1) and net return (` 56933 ha-1) followed by atrazine 50% WP @ 500 g a.i. ha-1 (PE) fb one hand weeding at 30 DAS fetched highest gross return (` 75573 ha-1) and net return (` 54620 ha-1) however, atrazine 50% WP @ 400 g a.i. ha-1 (PE) fb tembotrione 42% SC @ 90 g a.i. ha-1 at 25 DAS depicted higher profitability level in respect of B: C ratio (3.75). Weed free was obtained maximum profitability (` 686 day-1) followed by atrazine 50% WP @ 500 g a.i. ha-1 (PE) fb one hand weeding at 30 DAS (` 658 day-1) and atrazine 50% WP @ 400 g a.i. ha-1 (PE) fb tembotrione 42% SC @ 90 g a.i. ha-1 at 25 DAS (` 647 day-1).
