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.

    STUDIES ON DISTRIBUTION OF CALCIUM, MAGNESIUM, SULPHUR AND BORON IN SOILS OF SELECTED AGROCLIMATIC ZONES OF KARNATAKA
    (University of Agricultural Sciences GKVK, Bangalore, 19-08-11) NARENDRABABU, B; SUDHIR, K
    Soil samples were collected from different locations of northern dry zone, central dry zone, southern dry zone, southern transition zone and coastal zone of Karnataka and were analyzed for available Ca, Mg, S and B. Available Ca, Mg S and B of surface soil ranged from 825 to 1811 mg kg-1, 232 to 340 mg kg-1, 6.39 to 15.22 mg kg-1and 0.328 to 0.631 mg kg-1 in soils of different agro-climatic zones. Available Ca and Mg were highest in soils of northern dry zone and lowest in soils of coastal zone. Available S and B were highest in soils of coastal zone. Available S was lowest in soils of southern dry zone and available was lowest in soil of central dry zone. Available Ca was relatively higher, while available Mg, S and B were relatively lower in the deeper layer of soil as compared to surface layer of soils. Total Ca, Mg and S were much higher in the soils of dry zones as compared to the soils of transition and coastal zone. Coastal zone soils had higher proportion of organic S than soils of the central dry zone and southern transition zone. The four forms of boron together accounted for only 1-2 per cent of total boron in soils of all the five zones. Organic bound boron was relatively higher than those of specifically adsorbed boron and oxide bound boron in soils of most of the zones. Clay and CEC of soil were relatively higher in soils of dry zones as compared to that of coastal zone.

    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.

    STUDIES ON THE EFFECT OF VARIED LEVELS OF PHOSPHORUS AND ZINC ON GROWTH AND YIELD OF AEROBIC RICE (Oryza sativa L.)
    (11-09-12) VINAY, K; PRAKASH, S S
    A field experiment was conducted to study the effect of varied levels of phosphorus and zinc on growth and yield of aerobic rice (Oryza sativa L.)” (Cultivar rasi) during Kharif 2011 at ZARS, V. C. Farm, Mandya. Soil of the experimental site was medium in phosphorus and sufficient in zinc content. The experiment consisted of 3 levels of phosphorus (25, 50 and 75 kg ha-1) and 4 levels of zinc sulfate (0, 10, 20 and 30 kg ha-1) (12 treatments) laid out in Randomized Complete Block Design with three replications. Significantly higher grain and straw yield (3024 and 4027 kg ha-1, respectively) was recorded due to application of P at 75 kg ha-1 compared to application of P at 25 kg ha-1. But it was statistically on par with grain (2996 kg ha-1) and straw (3841 kg ha-1) yield obtained with 50 kg ha-1 P level. However, the effect of levels of zinc sulfate and interaction on yield was not significant. The uptake of P and K by aerobic rice increased significantly with increasing level of P application. Similarly, N, P, K uptake by straw varied significantly due to different levels of zinc sulfate. The interaction effect was also significant with regard to P and K uptake by straw. Higher B:C ratio was recorded due to application of P and ZnSO4 at 50 and 10 kg ha-1, respectively.
