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.

    ISOLATION AND CHARACTERIZATION OF STRESS TOLERANT PLANT GROWTH PROMOTING RHIZOBACTERIA AND THEIR INFLUENCE ON BLACKGRAM (Vigna mungo L.)
    (Acharya N.G. Ranga Agricultural University, 2017) ESWARA RAGHAVA KUMARI, M; VIJAYA GOPAL, A
    Stress tolerant Plant Growth Promoting Rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance plant growth under stress condition by production of ACC deaminase enzymes. In the present study 32 stress tolerant PGPR were isolated from rhizospheric soils of drought prone areas and were tested for different plant growth promoting activities. Out of 32 bacterial strains (8 Rhizobium isolates, 8 pseudomonas isolates, 8 potassium releasing bacterial isolates and 8 zinc solubilizing bacterial isolates) isolated from blackgram soils, four efficient PGPR strains, one each of Rhizobium (KUR1), pseudomonas (KCP1), potassium releasing bacterial (KGK1) isolate and zinc solubilizing bacterial (STZ1) isolate were selected for further studies. These four isolates contain higher ACC deaminase activity KUR1 (+++), KCP1 (+++), KGK1 (+++), STZ1 (+++) and produce higher exopolysaccharide KUR1 (34.6 mg ml-1), KCP1 (30.6 mg ml-1), KGK1 (20.3 mg ml-1), STZ1 (24.6 mg ml-1). All isolates were positive for siderophore production, IAA production and also phosphate solubilization efficiency. All the isolates were further screened in vitro for antagonistic activity against the fungal pathogen Rhizoctonia solani and found that all these isolates inhibited the fungal pathogen and highest inhibition was found with the isolates KUR1 (37.6%), KCP1 (39.53%), KGK1 (36.47%), STZ1 (36.07%). The selected strains were tested in soil to assess their effectiveness against stress tolerance by improving growth of blackgram under water stress conditions. Pot culture experiment was conducted with blackgram crop at different water holding capacity (80%, 60%, 40% and 20%). The results revealed that reduced soil moisture levels significantly decreased the growth of blackgram. However inoculation of blackgram with stress tolerant rhizobacteria containing ACC deaminase, isolated from the soils collected from drought prone areas significantly increased the drought tolerance in blackgram and increases the growth and yields. These stress tolerant PGPR improved the growth parameters like plant height (13.3 cm, 31.6 cm and 39.0 cm at 30 DAS, 60 DAS and75 DAS respectively), Number of branches plant-1 (4.73, 9.60, 11.60 at 30 DAS, 60 DAS and75 DAS respectively) and number of leaves plant-1 (13.3, 31.6, 39.0 at 30 DAS, 60 DAS and75 DAS respectively) increases. Number of pods plant-1 (32.3), number of seeds pod-1 (5.0), seed yield (2815.0 kg ha-1), 100 seed weight (4.98 gm) also increases. Other physico chemical properties of soil like pH (7.97), EC (0.98 dSm-1), Organic carbon (0.75%), N (283.40 kg ha-1), P (98.99 kg ha-1), K (324.73 kg ha-1) and enzymes like dehydrogenase (233.4 μg TPF formed g-1 d-1), phosphatase (Acidic 130.00 μg pNP g-1 h-1, Alkaline 148.00 μg pNP g-1 h-1), urease (121.62 ug urea g-1 h-1) also improved at flowering stage of blackgram. Proline content of plant was increases under stress condition. i.e., at 20% WHC, it was recorded as 64.33 μ moles g-1. N (0.55%), P (0.32%), K (2.21%) content of plant samples also increases. These results revealed that combined inoculation of stress tolerant PGPR significantly increased growth and yield of blackgram 42 percent more compared to control under moisture stress conditions.
