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.

    EFFECT OF DIFFERENT LEVELS OF ENRICHED PHOSPHATIC SLUDGE APPLICATION ON SOIL PROPERTIES, GROWTH, YIELD AND QUALITY OF MAIZE (Zea mays L.) AND PADDY (Oryza sativa L.) CROPS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-12-27) ERESH; PRAKASH, S. S.
    Analysis of enriched phosphatic sludge (EPS) revealed that it contained 11.30 per cent organic carbon, 6.88 per cent phosphorus and appreciable amount of other nutrients and can be used as manure in crop production. Incubation studies revealed that rate of release of major, secondary and micronutrients was higher in T7 (soil + EPS @ 1250 kg ha-1) over control under flooded condition. Pot culture experiments revealed that application of RDF + EPS @ 750 kg ha-1 significantly increased the plant height, dry matter production and nutrient uptake by paddy at 60 DAT. The heavy metal content in soil and plants were below detection limit. Further, field experiments revealed that kernel and stover yield of maize increased with increasing levels of EPS as compared to control and significantly higher kernel (90.84 q ha-1) and stover (110.80 q ha-1) yield and nutrient uptake was recorded due to application of RDF + 750 kg EPS ha-1 and it was on par with RDF + FYM @ 10 t ha-1. Grain (76.70 q ha-1) and straw (89.37 q ha-1) yield of paddy was higher with the application of RDF + 750 kg EPS ha-1. Nutrient status of soil after harvest of maize and paddy was improved in treatment which received RDF + 1000 kg EPS ha-1, RDF +750 kg EPS ha-1 and RDF + FYM @ 10 t ha-1. Economic analysis revealed that, highest B: C (2.50) was obtained in treatment T2 which received RDF + FYM 10 t ha-1 in maize and highest B:C (2.46) was obtained in treatment T6 which received RDF + 750 kg EPS ha-1 in case of paddy. The heavy metal elements content was below detection limit both in rice and maize kernel and in soil.

    FRACTIONS OF PHOSPHORUS, SULPHUR AND BORON IN SOIL UNDER LONG TERM FERTILIZER EXPERIMENTS OF FINGER MILLET-MAIZE AND RICE-COWPEA CROPPING SYSTEMS OF KARNATAKA
    (10-08-13) ERESH; GOWDA, R C
    Ongoing long term fertilizer experiments under finger millet-maize and rice-cow pea cropping systems at GKVK Bengaluru and VC Farm Mandya were selected to study the different fractions of phosphorus, sulphur and boron in soil. Besides the fractions, their available nutrient status was also studied. The results of the finger millet-maize cropping system indicated that application of chemical fertilizer in combination with FYM revealed that all the available nutrients were maintained. With respect to P fractions like Al-P, Fe-P, Occl-P and total-P were found to be higher in 150 % NPK applied treatment; however Ca-P was higher percent in treatment receiving 100 % NPK+FYM+Lime. Higher percent of available sulphur and its fractions were recorded in treatments receiving single super phosphate and lower availability and its fractions were noticed in T9-100%NPK-S and T7-100%N. Higher boron availability and its fractions were recorded in treatments receiving FYM along with chemical fertilizers. In rice-cow pea cropping system here also available nutrient status maintained in inorganic and FYM applied treatments .Higher phosphorus availability was recorded in treatment receiving STCR based fertilizer recommendation. Higher per cent of Al-P, Fe-P, Occl-P and total-P fractions were recorded in 100%NPK+Zn+S treatment. With respect to sulphur availability and its fractions 100%NPK+Zn+S recorded higher values. Available boron and its fractions were higher in FYM applied treatments compared to other treatments. Hence the application of recommended doses fertilizer in combination with FYM helps to better maintenance of soil health as well as available nutrient status of soil.
