Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    STUDIES ON INTERACTION DYNAMICS OF TRICHODERMA AND FUSARIUM OXYSPORUM IN RELATION TO WILT OF CHICKPEA
    (guntur, 2022-08-11) AMULYA, G.; ANIL KUMAR, P.
    In the present investigation on "Studies on interaction dynamics of Trichoderma and Fusarium oxysporum in relation to wilt of chickpea", 24 fields running across 12 villages in six mandals of Prakasam district, A.P were surveyed for the prevalence of Chickpea Fusarium wilt caused by Fusarium oxysporum f. sp. ciceri (Foc). The Fusarium wilt incidence ranged from 59.88% to 100% indicating impact of disease. Twenty four each of Foc and Trichoderma isolates were collected from the surveyed villages and studied for variability along with one isolate each of Foc and Trichoderma collected from College Farm, Agricultural College, Bapatla. Variability in Foc isolates was assessed for morphological characters such as macro and micro conidial length and width and cultural characters viz. medium pigmentation, texture, colony elevation, growth habit, colony margin and nature of mycelium. Based on the characters studied, 25 test isolates of Foc were segregated into different groups. Variability in Foc pathogenicity was observed in pot culture as effect on seed germination and wilt incidence. All the isolates were found equally pathogenic in causing wilt, though variation existed in affecting seed germination. SCAR marker with an amplicon size of ~207 bp specific to Foc was developed from Foc0-12 RAPD marker sequence of AF492451.1 clone available in genbank NCBI. Specificity and reliability of the SCAR marker was further confirmed by assessing F. moniliforme, other species of Fusarium and different other genera for which the result was negative. xx Variability assessment among the 25 test isolates of Trichoderma used in the present investigation was studied using the cultural and morphological characters. The 25 test isolates, accordingly were identified as T. longibrachiatum (4 No.s), T. pseudokoningii (1 No.s), T. virens (3 No.s), T. aureoviride (2 No.s), T. harzianum (4 No.s), T. asperellum (7 No.s) and T. viride (4 No.s). Molecular analysis of Trichoderma isolates using ITS primers revealed two clusters with 61% similarity. Based on studies on in-vitro dual culture studies, volatile and non volatile metabolites of Trichoderma and volatile metabolites of Foc and compatibility with biorationals, Trichoderma isolate T 19001 was selected as the most potential isolate for biocontrol of Foc. T 19001 was found to be effective under green house conditions when integrated with panchagavya, by not only increasing germination, root length and shoot length of chickpea, but also significantly reduced the disease incidence over pathogen check. Pooled analysis of the field experiment conducted during rabi 2018-19 and 2019-20 to assess the biocontrol potential of T 19001 in integration with biorationals revealed that seed treatment with T 19001 + Panchagavya @ 10% resulted in maximum disease control (35.9%) of chickpea wilt complex, yield (1586.5 kg/ha) and B:C ratio (2.40) and was on par with Tebuconazole seed treatment (1672.0 kg/ha and 2.42 B:C ratio). Beejaraksha and beejamrutha were inferior to panchagavya either alone or in integration with T 19001. Studies on interaction dynamics of Foc and T 19001 in pot culture revealed that T 19001 could lower the population of Foc and thereby decreasing chickpea wilt incidence. Further, increased dose / cfu of Foc warrants increased dose / cfu of T 19001 indicating that dose of Trichoderma should depend on the cfu of Foc in soil for better disease management tactics.
