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.

    EFFECT OF PHOSPHATE SOLUBILIZING BACTERIA ON GROWTH AND YIELD OF FINGER MILLET
    (Acharya N.G. Ranga Agricultural University, 2017) SAISREE, CHALLA; VIJAYA GOPAL, A
    Phosphate solubilizing bacteria (PSB) plays an important role in dissolving both of fertilizer phosphorus (P) and bound P in the soil that is environmental friendly and sustainable. Phosphate solubilization is mainly through the reaction between organic acids excreted with phosphate binders such as Al, Fe, and Ca, or Mg to form stable organic chelates to free the bound phosphate ion. Phosphorus deficiency is widespread and phosphorus fertilizers are required to maintain crop production. Reductions in the supply of P fertilizers could severely diminish crop yields. One solution for mitigating the threat of this diminishing resource is to develop sustainable technologies to improve P use efficiently for plant uptake. Since chemical fertilizers are frequently used with finger millet crop, use of PSB, as biofertilizers would help in improving better crop stand and crop yields. Sixteen PSB isolates were isolated from finger millet rhizospheric soils of twelve villages in Andhra Pradesh. All the 16 PSB isolates were able to solubilize phosphate qualitatively and quantitatively. The PSI for 16 PSB isolates were in the range of 6.61 to 2.62 qualitatively and all 16 PSB isolates were able to solubilize phosphate quantitatively in Pikovskaya’s broth containing TCP in the range of 189.5 to 41.3 mg l-1. The isolates were purified and they were culturally, morphologically and biochemically characterized. Biochemical characterization revealed that 9 isolates were positive for Voges Proskauer’s test and motility test, 10 isolates were positive for nitrate reduction and catalase test, 11 isolates were positive for citrate utilization and oxidase test, 8 isolates were positive for starch hydrolysis and methyl red test, 6 isolates were positive for gas and acid production and 13 PSB isolates were positive for indole production. These isolates were screened in vitro for plant growth promoting attributes like phosphate solubilization, siderophore, IAA, ammonia and HCN production. Results revealed that all 16 isolates solubilized phosphorous and 87.5% isolates produced ammonia, 75% isolates produced HCN, 56% isolates produced siderophores and 81% isolates produced IAA. All the isolates were further screened in vitro for antagonistic activity against the fungal pathogen Rhizoctonia solani and found that all isolates inhibited the fungal pathogen and highest inhibition was found with the isolate BKP2 (51.49%). The best 3 efficient PSB strains i.e., PSB1, PSB2 and PSB3 were selected by estimating the phosphorus solubilizing ability of isolates qualitatively as well as quantitatively and by determining the morphological, biochemical and plant growth promoting rhizobacterial properties of isolates. Therefore, the best 3 PSB strains were identified as Pseudomonas sp. (isolate name, BKP2) Bacillus sp. (isolate name, SSP1) and Enterobacter sp. (isolate name, SBP1). Pot culture experiment was conducted for evaluating the effect of PSB on growth and yield of finger millet. Results revealed that the highest microbial population (Bacteria, PSB, Fungi and Actinobacteria) was recorded at flowering stage compared to other growth stages while microbial population at flowering stage was more in the treatment (T5) with 75% RDP+PSB1+PSB2+PSB3. Root length (23.1 cm), no. of fingers plant-1 (10.0), phosphorus content in plant sample (0.183%), total dry matter (39.4 g plant-1) and yield parameters like grain yield (4031.9 kg ha-1) and straw yield (4691.5 kg ha-1) were recorded highest in the treatment (T5) with 75% RDP+PSB1+PSB2+PSB. The enzyme activities (acid phosphatase, alkaline phosphatase, dehydrogenase and urease) and soil physico-chemical properties (pH, EC, available N, P, K and Organic carbon) recorded highest at various stages of crop growth in the treatment (T5) with 75% RDP+PSB1+PSB2+PSB3. The results of this study clearly shows that finger millet growth and yield can be enhanced by inoculating soil with PSB biofertilizer along with recommended dose of FYM and by varying RDF in different treatments. Further, from this study it is also concluded that, soil fertility and soil health can be improved with the inoculation of soil with PSB biofertilizer.
