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 Stress Mitigating Chemicals and Sulphur on Growth and Yield of Mungbean [Vigna radiata (L.) Wilczek]

    A field experiment entitled “Effect of stress mitigating chemicals and sulphur on growth and yield of mungbean [Vigna radiata (L.) Wilczek]” was conducted at Instructional Farm, College of Agriculture, Jodhpur (Rajasthan) during kharif season of 2019. Field experiment was laid out in factorial randomized block design (FRBD) with sixteen treatment combinations and replicated thrice. The treatments were taken in the investigation viz. control (C0), salicylic acid @ 75 ppm at flower initiation stage + 7 DAFS (C1), salicylic acid @ 75 ppm + 2% urea at flower initiation stage (C2), thiourea @ 500 ppm at flower initiation stage (C3) under stress mitigating chemicals, however, control (S0), 20 kg sulphur/ha (S1), 30 kg sulphur/ha (S2) and 40 kg sulphur/ha (S3) under levels of sulphur. Result indicated that application of thiourea @ 500 ppm at flower initiation stage (C3) of mungbean significantly higher growth attributes viz. plant height (12.66, 44.88 and 57.35 cm), dry matter accumulation/plant (1.61, 16.79 and 21.89 g), SPAD chlorophyll meter reading (41.64, 52.90 and 35.31) at 25, 50 DAS and at harvest, respectively, while number of nodules/plant (24.73), fresh weight of nodules/plant (277.51 mg), dry weight of nodules/plant (41.63 mg), primary branches/plant (7.77) and secondary branches/plant (4.82) as well as significantly increase yield attributing characters viz. pod length (10.40 cm), number of pods/plant (40.78), grains/pod (11.30) and 1000-grain weight (42.40 g) resulted in higher grain (1055 kg/ha), stover (2246 kg/ha) and biological yield (3301 kg/ha) along with harvest index (31.86%) followed by the treatment sprayed with salicylic acid @ 75 ppm + 2% urea at flower initiation stage. However, thiourea @ 500 ppm at flower initiation stage (C3) and salicylic acid @ 75 ppm + 2% urea at flower initiation stage (C2) were statistically at par with each others with respect to yield attributes and yield of mungbean. Similar trends were also observed with nitrogen and sulphur contents in grain (3.86 and 0.287%) and stover (1.45 and 0.116%) results in higher uptake of nitrogen and sulphur by grain (40.72 and 3.04 kg/ha) and stover (32.57 and 2.63 kg/ha), respectively as well as protein content (24.13%) of mungbean and showed significant superiority over rest of the treatments. Increase in grain and stover yield, which subsequently improved gross returns ( 78,870 and 77349/ha), net returns ( 55,031 and 53735/ha) and B: C ratio (3.31 and 3.28) due to application of thiourea @ 500 ppm at flower initiation stage (C3) and salicylic acid @ 75 ppm + 2% urea at flower initiation stage (C2), respectively. Results further revealed that among doses of sulphur, 40 kg sulphur/ha (S3) was remain at par with 30 kg sulphur/ha (S2) with respect to all parameters taken during experimentation. Application of 40 kg sulphur/ha (S3) significantly increased growth attributes mungbean viz. plant height (13.01, 43.44 and 54.48 cm), dry matter accumulation/plant (1.70, 16.38 and 21.69 g), SPAD chlorophyll meter reading (42.41, 52.27 and 34.52) at 25, 50 DAS and at harvest, respectively, while number of nodules/plant (25.17), fresh weight of nodules/plant (267.43 mg), dry weight of nodules/plant (40.62 mg), number of primary branches/plant (7.26) and secondary branches/plant (4.71) that enhanced yield attributing characters viz. pod length (10.35 cm),number of pods/plant (40.38), number of grains/pod (11.42) and 1000-grain weight (42.33 g) resulted in higher grain (1062 kg/ha), stover (2297 kg/ha) and biological yield (3359 kg/ha) along with harvest index (31.62%) over its lower dose i.e. 30 kg sulphur/ha (S2), 20 kg sulphur/ha (S1) and control (S0). It also recorded significantly higher nitrogen and sulphur contents in grain (3.73 and 0.269%) and stover (1.33 and 0.105%) results in higher uptakes of nitrogen and sulphur by grain (39.61 and 2.89 kg/ha) and stover (30.56 and 2.44 kg/ha), respectively as well as protein content (23.31%) of mungbean over rest of the treatments, but remained at par with 30 kg sulphur/ha (S2). Improvements in yield, of mungbean, which subsequently improved gross returns ( 79448 and 78355/ha), net returns ( 53603 and 53732/ha) and B: C ratio (3.07 and 3.18) under the treatment of 40 kg sulphur/ha followed by 30 kg sulphur/ha, respectively. On the basis of net return and B: C ratio, application of thiourea @ 500 ppm at flower initiation stage (C3) along with 30 kg sulphur/ha was more remunerative treatment in mungbean as compared to rest of the treatments.
