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.

    USE OF SUGARCANE BY-PRODUCTS AS SUBSTRATE FOR CULTIVATION OF OYSTER MUSHROOM (Pleurotus sajor-caju (Fr.) Singer)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1998-08-19) CHANDRASHEKAR, B. S.; SAVALGI, VEENA
    Studies were conducted on sugarcane by-products (sugarcane trash, milled bagasse and crushed bagasse) as substrate for raising crop of Pleurotus sajor-caju for yield as well as the suitability of the spent straw as manure. Milled bagasse and sugarcane trash revealed highest sporophore yield of P. sajor-caju when treated with sodium hydroxide (at 4 and 2%) and calcium hydroxide (at 4 and 3%). Among sodium hydroxide treated combinations, sugarcane trash and milled bagasse promised highest bio-efficiency of P.sajor-caju, similar combination performed better when substrates were treated with calcium hydroxide. But, calcium hydroxide treatment was found to be inferior on sporophore yield over sodium hydroxide treatment. This above mentioned substrate combination treated with sodium hydroxide also revealed highest bio-efficiency and protein content of sporophores on amending with soybean grits (1%) over rice bran (1%). Even similar trend was noticed in calcium hydroxide treated combination of substrate. But paddy straw was found to be a superior substrate for bio-efficiency and protein content of P.sajor-caju when amended with soybean grits (1%). Even spent substrate of paddy straw obtained after mushroom harvest showed greater influence on yield of brinjal and plant dry matter production when used as manure (FYM). Whereas, in sugarcane by-products, sodium hydroxide treated and soybean grits amended substrate on application as FYM resulted in moderately good yield and plant dry matter brinjal over calcium hydroxide treated and amended substrate.

    STUDIES ON MINERAL PHOSPHATE SOLUOILIZINC FUNGI FROM VERTISOLS OF NORTHERN KARNATAKA AND THEIR RIOFERTILIZER POTENTIAL
    (University of Agricultural Sciences GKVK, Bangalore, 2005-06-14) CHANDRASHEKAR, B. S.; A. R. ALAGAWADI
    STUDIES ON MINERAL PHOSPHATE SOLUIBILIZING FUNGI FROM VERTISOLS OF NORTHERN KARNATAKA AND THEIR BIOFERTILIZER POTENTIAL CHANDRASHEKHAR B. S. 2003 ABSTRACT Dr. A. R. ALAGAWADI MAJOR ADVISOR Attempts were made to isolate mineral phosphate solubilizing fungi from the vertisols of Northern Karnataka and their relationship with soil physical, chemical and biological properties were analysed. The correlation coefficient worked out for the soil properties to that of PSF population indicated that highly significant positive correlation existed between PSF population and that of total fungi. The total phosphorus content, organic carbon, available nitrogen and total bacterial population showed significant positive correction with that of PSF population, where as other properties had negative and non-significant correlation with PSF population. In a further investigation to develop a suitable PSF isolate for vertisols, 67 PSF isolates from rhizosphere of various crop plants grown on vertisols were identified up to generic level and screened for their efficiency to^^raWlize different insoluble phosphates. Aspergillus was the predominant genera among the isolates. Thirty-five efficient PSF isolates were then analysed for production of organic acids, lAA and OA. Most of the isolates produced 3-4 different organic acids, as well as lAA and OA. Based on the efficiency of MPS, lAA and OA production, 16 efficient isolates were selected for pot culture experiment with green gram and sorghum as test plants. Most of the PSF isolates significantly enhanced the nodulation, growth, dry matter content, and P uptake in green gram plants at 45 DAS over RP control. The growth, diy matter content, P uptake and yield of sorghum plants were also enhanced significantly over RP control. Based on the performance under greenhouse conditions, eight most efficient isolates were selected for field performance with green gram as test crop. All the isolates significantly increased the grain yield of green gram over RP control. However, isolates PSF 11 and PSF58 showed significantly higher grain yield over SSP control. An attempt was also made to mutagenise four chosen MPS fungal isolates using gamma irradiation. The selected mutants were checked for solubilization of different insoluble phosphates and also for organic acid profiles. The hyper mutants, which showed bigger zone of solubilization on Pikovskaya's agar medium, also enhanced the growth, dry matter and P uptake of sorghum plants in greenhouse condition at 45 DAS over RP control, SSP control and also over their respective parent strains.
