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.

    STATUS AND NUTRITION OF ZINC AND IRON IN RICE AND SOILS OF DIFFERENT AGRO-CLIMATIC ZONES OF KARNATAKA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2014-07-10) CHAKPRAM, BIRENDRAJIT; Prakash, N B
    An investigation was conducted to study the status of Zn and Fe content in rice genotypes and soils across different agro climatic zones (ACZ) of Karnataka and for Zn and Fe content and its uptake in rice following soil and / foliar application of their different sources under aerobic and wetland cultivation. The grain and straw Zn content across 64 rice genotypes ranged from 7.8 to 51.3 mg kg-1 and 16.6 to 284.0 mg kg-1, respectively. The grain and straw Fe content ranged from 9.6 to 88.8 mg kg-1 and 39.7 to 437.5 mg kg-1, respectively. In general, 36 per cent of soil samples collected representing eight ACZ were below the critical limit of 0.6 mg kg-1 Zn in soil. All the soil samples were above the critical limit of 4.5 mg kg-1 Fe in soil. The Zn and Fe content and its uptake by rice grain and straw in field experiment and grain, straw and root in PVC pipe experiment was higher in aerobic and wetland rice cultivation, respectively. Rasi genotype recorded higher Zn and Fe content and their uptake by grain, straw and root under both aerobic and wetland cultivation. Application of different sources of Zn and Fe to soil and foliar combination recorded higher content of Zn and Fe in grain and straw compared to soil application alone. Zn-EDTA and Fe-EDTA performed better than ZnSO4 and FeSO4 based on per unit of Zn/Fe application in achieving higher Zn and Fe content, respectively in grain and straw in all the experiments.

    Studeis on Persistence and Degradation of Propineb and Its Effect on Zinc Content in Rice
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2008-02) CHAKPRAM, BIRENDRAJIT; Prakash, N B
    A laboratory and two field experiments were conducted in order to determine the persistence and degradation of propineb in soils, rice and its effect on zinc content in rice. Persistence of Propineb was studied in Shimoga and Mandya soils at the application rate of 10 and 25 pg g"1. The degradation pattern of Propineb in soils followed the first order reaction kinetics and was faster in initial period of incubation and later slower degradation. Degradation of Propineb was faster under field capacity moisture regimes than submergence. Higher persistence of Propineb was noticed in Shimoga soil than Mandya soil at both the application rates and moisture regimes. The half life values ranged from 5.2 to 5.3 days in Mandya soil and from 6 to 9.6 days in Shimoga soil following application at 10 and 25 pg g"1 under field capacity. It ranged from 6.7 to 7.7 days and 10 to 12.1 days in Mandya and Shimoga soil under submerged moisture regimes. Propineb residues dissipated faster in rice when applied at 700 and 1400 g a.i. ha-1on 20 or 30 days after transplanting. Dissipation was faster at lower dose than higher dose of application. The rate of degradation of propineb residues was higher when applied at 30 days after transplanting (DAT) as compared to 20 DAT. The half-life values varied according to the difference in time of application irrespective of rate of application. Half-life values of propineb when applied at 20 DAT ranged from 1.96 to 2.29 days and from 1.25 to 1.59 days when applied at 30 DAT. There was a significant increase in grain and straw yield over control in the application of zinc based fungicide and fertilizers. Although no significant difference in zinc content was observed, there was a significant difference in zinc uptake by grain and straw among different treatments.
