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.

    Phosphorus release characterstics, forms and plant uptake in Alfisols of deferential P status
    (University of Agricultural Sciences GKVK, Bangalore, 07-10-11) EMAL; RAMAKRISHNA PARAMA, V R
    The different forms of phosphorus were determined in soils varying in P status (high, medium and low). The soils varying in P status was collected from three villages of Bangalore rural taluk, namely Kariberanahoshalli (high P soil), Devanahalli (medium P soil) and Devanahahalli (low P soil) respectively. Similarly three such types of soils were collected from different locations in GKVK campus of University of Agricultural Sciences Bangalore. The soils were sourced from horticulture plot (high P soil), AICRP on soil test and crop response plot (medium P soil) and Sericulture plot (low P soil). The results showed that he bulk density (1.40 Mg m-3), available P and K (161.00 and 336.90 kg ha-1) respectively, phosphorus buffering capacity (26.20%) and Fe-P (79.56 mg kg-1) were high in the high P soil of Kariberanahoshalli, Bangalore rural taluk. The particle density (3.00 Mg m-3), pH (6.85), available N (334.90 kg ha-1), exchangeable Ca (4.85 cmol P+ Kg-1) and Al-P (86.62 mg kg-1) were high in medium P soil of Devanahalli, Bangalore rural taluk. The maximum water holding capacity (40.29 %), cation exchange capacity (15.4 cmol P+ Kg-1), total P (268.70 mg kg-1) and occld-P (19.34 mg kg-1) were high in low P soil of Devanahahalli, Bangalore rural taluk. In GKVK campus soils, the MWHC (33.10 %), pH (6.7), exchangeable Ca (4.20 cmol P+ Kg-1), and available S (19.50 mg kg-1) were high in high P soil of horticulture plot. The available P (51.80 kg ha-1), total P, Fe-P and Ca-P (411.65, 89.21 and 14.19 mg kg-1) respectively were high in medium P soil of on soil test and crop response plot. The BD (1.35 Mg m-3), pH (5.60), exchangeable Ca and Mg (4.50 and 2.30 cmol P+ Kg-1), Al-P and RS-P (59.21 and 42.00 mg kg-1) were high in low P soil of Sericulture. The change of P fractions during period of cowpea growth in the soils of varying P status was evident. This was indicated by the change in the order of the fractions in the initial (Al-P > Fe-P > RS-P > Occld-P > Sal-P > Ca-P) and residual (Al-P > Fe-P > RS-P > Occld-P > Ca-P > Sal-P) soil samples.
