University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    EFFICACY OF PHOSPHATE SOLUBILIZING BIOFERTILIZERS WITH DIFFERENT SOURCES AND LEVELS OF PHOSPHORUS IN CHICKPEA (Cicer arietinum L.)
    (University of Agricultural Sciences, Bangalore, 1996) D'SOUZA, SAVITA P; ALAGAWADI, A R
    In a field experiment conducted at the Main Research Station, University of Agricultural Sciences, Dharwad, during Rabi season of 1995-96, the efficacy of two phosphate solubilising bio fertilizers in combination with two sources and four levels of phosphorus on the growth, nutrient uptake and yield of chickpea was studied. The results revealed a significant increase in nodulation, dry matter accumulation, nutrient uptake and yield of chickpea due to inoculation of Bacillus polymyxa and 'biophos' over uninoculated control. The inoculation effects were more pronounced in the presence of added phosphate fertilizers. B. polymyxa among the two bio fertilizers and single superphosphate (SSP) among the two sources of phosphorus had greater impact on the yield of chickpea. Phosphorus applied at 100 and 75 per cent recommended dose showed maximum influence on the nodulation, growth, yield, nutrient uptake and seed protein content of chickpea. Inoculation of phosphate solubilising biofertilizers in combination with application of either SSP at 75 per cent recommended level or Gafsa rock phosphate (GRP) at 100 per cent recommended level showed almost same yield as that of standard practice of applying SSP at 100 per cent recommended dose without inoculation. The population of total bacteria, fungi, actinomycetes and P-solubilizers in the rhizosphere of chickpea was also enhanced due to inoculation of P-solubilising bio fertilizers and application of phosphatic fertilizers. While inoculation of B.polymyxa enhanced the population of total bacteria and P-solubilizers, 'biophos' inoculation showed higher population of fungi. The available P-content of soil was also higher in the treatments receiving?-solubilising bio fertilizers over uninoculated control. Treatment receiving SSP showed higher available phosphorus in soil at the initial stages of crop growth and declined at later stages but with GRP application, soil available phosphorus was found to increase steadily even up to harvesting stage.

    FLUORESCENT PSEUDOMONADS AS BIOCONTROL AGENTS OF COLLAR ROT OF GROUNDNUT CAUSED BY SCLEROTIUM ROLFSII SACC
    (University of Agricultural Sciences, Bangalore, 1996) PATIL, RAJENDRA P; JAGADEESH, K S
    As many as 40 fluorescent bacteria were isolated from roots of various crop plants and weeds grown invertisols. These isolates were subjected to various microbiological and biochemical tests and confirmed as "fluorescent pseudomonads". These strains were screened in vitro for their antagonism against Sclerotiumrolf. Based on their ability to form the zones of inhibition, two efficient strains were selected. The strain (FPD- 10) isolated from silver oak roots produced a maximum zone of inhibition of 47mm, while the other strain (FPD - 15) isolated from groundnut roots showed 43mm. These strains were identified as Pseudomqnas fluorescens through various biochemical tests. Pseudomonas fluorescens strains FPD- 10 and FPD -15 were assayed for their competitive saprophytic abilities in terms of inhibition of sclerotial germination and their multiplication and survival. Both the strains significantly inhibited sclerotial germination in vitro as well as in vivo. And, FPD - 15 strain multiplied faster than FPD - 10 both in sterile as well as unsterile soil conditions. Further, both the strains were found to be compatible with Bradyrhizobium spp. strain NC -92. The growth promotion and bio control potentials of the two strains were evaluated under green house conditions . It was found that P. fluorescens strain FPD - 15 significantly increased seed germination , nodulation , dry matter production and pod yield , besides protecting the plants from sclerotial infection . When compared to the fungicide (Capitan) treatment, FPD- 15 strain increased seedling emergence by 16 per cent, nodulation by 18 per cent , dry matter production by 40 percent and total pod yield by 65 per cent , and resulted in 84 per cent of survival of plants till harvest. These were further improved under biogas manure amended conditions.
