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 SCREENING OF DROUGHT AND SALINE TOLERANT RHIZOSPHERIC PLANT GROWTH PROMOTING BACTERIA FROM SALINE SOILS AND THEIR EFFECT ON GROWTH AND YIELD OF GROUND NUT (Arachis hypogaea L.)
    (Acharya N.G. Ranga Agricultural University, 2018) NARENDRA REDDY, A; VIJAYA GOPAL, A
    Stress tolerant plant growth promoting rhizobacteria (PGPR) can enhance plant growth under stress conditions by production of exopolysaccharides and ACC deaminase enzyme activity. In the present study 48 stress tolerant PGPR were isolated from rhizospheric soil of saline effected areas and were tested for different plant growth promoting activities. Out of 48 isolates, 15 were Rhizobium, 15 Pseudomonas, 10 sulphur oxidizing bacteria (SOB) and 8 potassium releasing bacteria (KRB). Out of these 48, one efficient isolate was selected from each group i.e., Rhizobium (BRR3), Pseudomonas (VKP2), potassium releasing bacteria (AKK2) and sulphur oxidizing bacteria (NJS2) for further studies. These four isolates contain high ACC deaminase activity [BRR3 (+++), VKP2 (+++), AKK2 (+++), NJS2 (++)] and high exopolysaccharide production BRR3 36.2 mg ml-1, VKP2 30.2 mg ml-1, AKK2 21.6 mg ml-1, NJS2 24.6 mg ml-1. All the isolates were positive for the production of siderophore, IAA, ammonia and phosphate solubilization. These selected strains were tested in soil to assess their effectiveness against stress tolerance to improve the growth of groundnut under moisture stress conditions in saline soils. Pot culture experiment was conducted with groundnut crop at different water holding capacities (25 %, 50 % and 75 % WHC). The results revealed that reduction in soil moisture levels significantly reduced the growth of groundnut. However, inoculation of groundnut with stress tolerant rhizobacteria isolated from saline effected areas containing ACC deaminase and exopolysaccharide production ability significantly increased stress tolerance and enhanced the growth and yields of groundnut. These stress tolerant PGPR improved the growth parameters like plant height (35.50 cm), number of nodules per plant (69), number of pods per plant (11.0), number of seeds per pod (1.8) and also seed yield (1415.7 kg ha-1) compared to control without inoculation. 20 Application of stress tolerant bacteria significantly enhanced the activity of soil enzymes like dehydrogenase (226.50 μg of TPF g-1 of soil d-1), phosphatase (alkaline 140.23 μg pNP g-1 h-1, acidic 125.0 μg pNP g-1 h-1) and urease (119.03 μg urea g-1 h-1), highest enzyme activity observed at flowering stage of groundnut when all the PGPRs applied in combinations. Other Physico-chemical properties of soil like pH (7.90), EC (3.27 dSm-1), organic carbon (0.77 %), nitrogen (398.18 kg ha-1), phosphorous (96.99 kg ha-1), potassium (436.73 kg ha-1) and N, P, K content of plant (1.71, 0.63 and 1.81 % respectively) also improved at flowering stage of groundnut. In addition to this proline content of plant was increased under stress conditions i.e., at 25 % WHC, it was recorded as 66.97 μ moles g-1. Finally, from these results it is concluded that combined application of stress tolerant PGPRs significantly increased the growth and yield of groundnut by 38.63 %. 33.89 % and 26.26 % at 75 %, 50 % and 25 % moisture levels respectively compared to control.
