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.

    SYNTHESIS AND CHARACTERIZATION OF NANO-IRON FROM GREEN BIOMASS AND EVALUATION OF ITS EFFECT ON AEROBIC RICE (Oryza sativa L.)
    (University of Agricultural Sciences, Bangalore, 2021-09-01) AKSHAY KUMAR, KURDEKAR; JAYADEVA, H. M.
    The laboratory and field experiments on synthesizing the nano iron from green biomass and evaluation of its effect on aerobic rice were conducted during 2020-21 at Zonal Agricultural Research Station, GKVK, UAS, Bangalore to optimize the quantity of nano iron required to overcome the iron deficiency in aerobic rice. The synthesis of ironman particles was done using various biomass and characterization was carried out by various physico- chemical techniques, nano iron synthesized using Bidens Pilosa leafextract shown UV- Vis spectroscopy analysis absorption peak at 319 nm and size of synthesized nano iron was 63.99 nm when measured through particle size analyzer. Furthersynthesized nano iron was used for seed treatment and field evaluation. Laboratory experiment with sixteen treatments was laid out in CRD and replicated thrice. The resultsrevealed that, seed priming with 1000 ppm of synthesized nano iron for 30 minutesrecorded higher germination (100 %), root length (15.97 cm), shoot length (15.91 cm) andseed vigour index (3188.0). In field, 9 treatments were laid out in RCBD with threereplications and the cultivar used was KMP-175. The results revealed that seed treatment with 1000 ppm of synthesized nano iron for 30 minutes and foliar application ofsynthesized nano iron at 800 ppm with RDF recorded higher plant height (92.11 cm),number of tillers (43.62 no plant-1), number of leaves (113.3), leaf area (2997 cm2 plant-1),total dry matter (113.95 g plant-1), productive tillers (23.8 tillers plant-1), panicle length(24.33 cm), total number of grains panicle-1 (147.0), per cent chaffyness (8.2 %) andultimately resulted in higher grain yield (7350 kg ha-1), stover yield (10050 kg ha-1), highernet returns (88526 Rs. ha-1) and B:C ratio of 2.78.
