Agriculture University, Kota

The Agriculture University, Kota (AUK) was established on 14th September, 2013 after bifurcation of the Maharana Pratap University of Agriculture & Technology (MPUAT), Udaipur and Swami Keshwanand Rajasthan Agricultural University (SKRAU), Bikaner through promulgation of Act No. 22 of 2013. The University has been created for the agricultural development in South-East and Eastern Rajasthan which is having diversified agriculture situations from rainfed to canal irrigated agriculture. The Agriculture University has its Headquarter at Borkhera Farm, Kota & is located on Kota-Baran National highway-76. Kota district is situated in the South-Eastern part of Rajasthan and comes under Humid South-Eastern Plain Zone (agro climatic zone V). It lies between 23045’ and 26038’ North latitude and 75037’ and 77026’ East longitude. The jurisdiction of AUK is spread over in 6 districts namely Kota, Baran, Bundi, Jhalawar, Karauli and Sawai Madhopur. It accounts for 9.98 % geographical area, 12.67 % total human population, 9.4 % live stock population, 31.59 % forest area and 20.6 % net sown area of the state. Development and education of modern practices in the field of Agriculture, Horticulture & Forestry for sustainable livelihood of the rural masses is the main thrust of the service area of AUK.

    “Investigations on Alternaria alternata Causing Blight Disease in Tomato (Solanum lycopersicum L.)”
    (COLLEGE OF AGRICULTURE, UMMEDGANJ, KOTA, 2020-09-26) Jewaliya, Balram; Gautam, Chirag
    Among the several diseases of tomato, leaf blight disease caused by Alternaria alternata is one of the most destructive disease which causes heavy losses in fruit yield of tomato. Per cent disease index (PDI) varied from 34.34 to 49.98 per cent in four surveyed districts viz., Kota, Bundi, Baran and Jhalawar of Hadoti region of Rajasthan. Maximum PDI was recorded in Charchoma village of Kota district (49.98%) while minimum was recorded in Azampur village of Jhalawar district (34.34%). Among the districts, disease severity was found to be maximum in Kota (44.06%), while least in Jhalawar (38.08%). The Pathogen was isolated from infected tomato plants showing typical leaf blight symptoms, purified and its pathogenicity was proved. The pathogen produced dark brown to black colony with septate mycelium and acropetal chain of ellipsoidal brown or muriform conidia, thus identified as Alternaria alternata which was further got confirmed by ITCC, Division of Plant Pathology, IARI, New Delhi (Ref. ID 11, 291.20). Cultural and morphological variability regarding colony diameter, colony colour, growth pattern, margin colour, topography, thickness of mycelium mat and sporulation were observed among seven isolates of Alternaria spp., collected during survey. AltKo1 isolate from Charchoma village of Kota showed maximum growth and sporulation on Potato dextrose agar (PDA) medium. Among seven solid culture media, PDA medium found better for mycelium growth and sporulation of Alternaria alternata. Out of seven liquid media, Oat meal broth gave maximum dry mycelium weight followed by Potato dextrose broth. Among seven fungicides tested, Hexaconazole @ 5 EC recorded maximum inhibition of mycelial growth (with mean 97.96%) at all concentrations under in vitro condition. Out of four bio-agents tested, Trichoderma harzianum found most effective followed by Trichoderma viride under in vitro condition. Out of six botanical extracts tested in vitro, Azadirachta indica (leaf extract) gave best result with 96.11 per cent inhibition of mycelial growth followed by seed extract of Azadirachta indica (94.11%).
