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.

    Evaluation of Different Species and Substrates for Cultivation of Oyster (Pleurotus spp.) Mushroom
    (Agriculture University, Jodhpur, 2022-07-11) Khan, Ajjad; Ram, Dama; Verma, Jeeva Ram; Singh, L. Netajit
    Mushroom is a large macroscopic fruiting body of fleshy, spore-bearing, multi-cellular edible fungi belong to division Basidiomycota. It is widely used in both food and medicine, it is a rich source of protein, vitamins and minerals. The effect of different media on the growth of Pleurotus spp. In vitro, different media (PDA, MEA, REA, and OMA) were evaluated to find out optimum medium for growth of Pleurotus species. The study on the effect of four media on the growth of oyster mushrooms indicated that the mycelial growth of P. eryngii was significantly more on oat meal agar (86.00 mm). However, minimum mycelial growth (40.00 mm) was observed on rice extract agar media. In case of P. sajor-caju the maximum mycelial growth was observed on oat meal agar (90.00 mm) and malt extract agar (90.00 mm) media, which was at par with each other, while minimum mycelial growth (65.00 mm) was observed on rice extract agar medium, and in case of P. sapidus the maximum mycelial growth was recorded on oat meal agar media (90.00 mm) and potato dextrose agar media (90.00) was at par with each other after 8 days of inoculation, while minimum mycelial growth (35.00 mm) was observed on rice extract agar media. The effect of the different substrates viz., wheat straw, sorghum straw, mustard straw, pearl millet straw and wheat + sorghum straw were evaluated for cultivation of oyster mushroom in the present study. In all three species namely P. eryngi, P. sajor-caju and P. sapidus, wheat straw showed the fastest spawn run, pin head formation, fruiting bodies formation, and minimum days required for first, second and third harvesting of mushroom followed by mustard straw, while maximum days for mycelium formation was observed on pearl millet straw. The total yield and biological efficiency, in case of P. eryngii the maximum total yield and biological efficiency was observed on wheat straw (698.33g and 69.83 per cent), while minimum total yield and biological efficiency was observed on pearl millet straw (576.69g and 57.69 per cent). In case of P. sajor-caju the maximum total yield and biological efficiency was observed on wheat straw (787.12.g and 78.71 per cent), while minimum total yield and biological efficiency was observed on pearl millet straw (590.45g and 59.04 per cent). In case of P. sapidus the maximum total yield and biological efficiency was observed on wheat straw (546.99g and 54.69 per cent), while minimum total yield and biological efficiency was observed on sorghum straw (398.45g and 39.84 per cent). The benefit: cost ratio, the maximum benefit: cost ratiofor P. sajor-caju was observed on mustard straw (5.96:1) followed by pearl millet straw (4.47:1) and wheat straw (3.56:1) while minimum benefit: cost ratio was observed on wheat + sorghum straw (3.25:1). In P. eryngii, maximum benefit: cost ratio was reported on mustard straw (5.86:1) followed by pearl millet straw (4.38:1) and wheat straw (3.55:1) while minimum benefit: cost ratio was observed on wheat + sorghum straw (3.25:1). In P. sapidus, maximum benefit: cost ratio was found on mustard straw (5.80:1) followed by pearl millet straw (4.29:1) and wheat straw (3.35:1) while minimum benefit: cost ratio was observed on wheat + sorghum straw (3.10:1).
