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 SUPPRESSION OF BACTERIAL LEAF BLIGHT AND PLANT GROWTH PROMOTION BY RICE ENDOPHYTIC BACTERIA”
    (ACHARYA N G RANGA AGRICULTURAL UNIVERSITY, GUNTUR, 2019) .KAVITHA, K; NAGAMANI, P
    Rice (Oryza sativa L.) is an economically important cereal crop in different areas of world especially in Asia. It is severely affected by the bacterial leaf blight in regions of Asia with heavy rainfall during monsoon. BLB pathogen, Xanthomonas oryzae pv. oryzae was isolated from the diseased plants and the pathogenicity of the isolated culture was demonstrated by clip inoculation method on rice cultivar NLR 34449 and confirmed as Xanthomonas oryzae pv. oryzae. A total of 45 endophytic bacterial isolates were obtained from the healthy leaf samples of MTU-1010, BPT-5204 and NLR-34449 cultivars and out of which, 19 isolates were from nine villages spread across six mandals of the Nellore district. Similarly 26 isolates were from four villages spread across three mandals of the Chittoor district. Among the 45 endophytic bacterial isolates evaluated for the antagonistic efficacy by Agar Well Diffusion method, 12 isolates with inhibition zone diameter of more than 10.00 mm were considered for the Morphological, Molecular and Biochemical characterization. Among the 12 endophytic bacterial isolates, EMP-5 showed maximum inhibition zone of 16.8 mm followed by EBK-3 with 16.6 mm. Morphological characterization of the 12 isolates revealed the dominance of Gram negative bacteria with rod shaped cells over the Gram positive bacteria. With regard to Plant growth promoting (PGP) traits, EMP-5 showed positive for Phosphate solubilization, Siderophore production, HCN production, Ammonia Production, Amylase activity and Protease production. Molecular characterization of the selected endophytic isolates by 16S rRNA was carried for identification of bacterial endophytes. 16 S rRNA gene xv sequence of the EMP-5 isolate was compared with 16 S rRNA gene sequence available at NCBI database through BLASTN search. Isolate EMP-5 showed close similarity of 99.06 per cent with query cover of 98 per cent with Enterobacter asburiae. As per the results of the antagonistic efficacy studies and biochemical characterization, EMP-5 (Enterobacter asburiae) was selected for field studies. Among all the treatments, treatment T5 (i.e. seed bacterization with EMP-5 @ 109 cells /ml + foliar application of EMP-5 @109 cells / ml) recorded showed reduction in per cent disease index (4.92 %) increased plant growth promoting ability with plant height of 80.8 cm, increase in the no. of effective tillers (97.4 %), grain yield (5340 kg/ ha) and straw yield (6013 kg/ha) over the untreated control. Plant disease suppression and growth promotion are complex interactive processes that may be addressed by plant heightening using endophytic bacteria possessing plant growth promoting traits. The results strongly emphasize that endophytic bacteria (EMP-5) characterized in the study could be efficiently used for management of bacterial leaf blight and for plant growth promotion. The isolate has the potential to be developed into a bio-inoculant for sustainable rice production.
