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 PACKAGING MATERIALS AND ZEOLITE ON SEED LONGEVITY OF ONION SEEDS (Allium cepa L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-01) AKSHATHA., K. S; NARAYANASWAMY, S.
    A laboratory experiment was conducted to study the effect of packaging materials and zeolite on seed longevity of onion seeds (Allium cepa L.) at Department of Seed Science and Technology, UAS, GKVK, Bengaluru during 2016-17. The study comprised of four packaging materials viz., cloth bag, aluminium foil, vacuum polythene bag and super grain bag and two types of zeolite viz., zeolite powder and zeolite beads stored for 10 months with FCRD in three replications. The results revealed that among the packaging materials, the seeds stored in aluminium foil recorded highest seed quality attributes viz., germination (70.49 %), seedling length (11.21 cm), seedling dry weight (1.91 mg), seedling vigour index I (792), speed of germination (0.806), dehydrogenase activity (1.124 A480nm), amylase activity (72.4 μg/g), moisture content (8.52 %), electrical conductivity (727 μS/ppm) and total soluble sugars (125.63 μg/ml) at the end of ten months of storage. Among the zeolite types, seeds dried to 5 per cent moisture content using zeolite beads resulted in higher seed quality parameters viz., germination (68.97 %), seedling length (10.64 cm), mean seedling dry weight (1.88 mg), seedling vigour index I (739), speed of germination (0.806), dehydrogenase activity (1.115 A480nm), amylase activity (74.8 μg/g), moisture content (8.90 %), electrical conductivity (743 μS/ppm), and total soluble sugars (124.45 μg/ml) was observed at the end of ten months of storage. The study can be concluded that the onion seeds dried to 5 per cent moisture content using zeolite beads and stored in aluminium foil could be stored for ten months satisfactorily.

    STUDIES ON INTEGRATED APPROACH FOR ENHANCING PLANT GROWTH, SEED YIELD AND QUALITY IN FINGER MILLET (Eleusine coracana L. Gaertn)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-09-10) CHINTHALAPATI, SRAVANI; Narayanawamy, S
    Finger millet is an important minor millet crop mostly cultivated owing to its calcium, iron and fibre content. In recent years selective utilization of crops, varieties and chemical fertilizers have threatened agro-biodiversity leading to rapid erosion of natural resources and consequently affecting the nutritional security of people. Considering impact of this, a field experiment was carried out to study the "Influence of integrated approach on enhancing plant growth, seed yield and quality parameters in finger millet" at J-Block, NSP, GKVK, UAS, Bengaluru during kharif 2015. The treatment combinations were arranged in split split plot design with two replications which includes different methods of sowing in main plot viz., (S1-direct sowing and S2-transplanting and four nutrient managements) in subplots (N0-without fertilizer, N 1-organic fertilizers, Ni­chemical fertilizers, N3-integrated) and subsubplots consists of priming treatments (Po­without priming, P1-hydropriming, P2-chemopriming and P3-biopriming). The results revealed that, S2 transplanting method of sowing, N3 integrated application of RDF- 100:50:50 NPK kg ha-1 in the form of neem + verrnicompost +urea+ SSP + MOP and P2 chemopriming with (2 % ) KH2P04 for 6 hours recorded highest growth, seed yield and quality attributes viz., field emergence (93.00 %), chlorophyll content (1.924 mg g-1 FW), number of tillers (14), ear head weight per plot (9.53 kg), germination (95.00 %), mean seedling length (18.45 cm), less number of fresh ungerminated seeds (5) and seed yield of (36. 78 q/ha ) when compared to ( control) direct sown without any nutrient and priming (14.68 q/ha).

    STUDIES ON BIO-PRIMING OF PADDY SEEDS TO COMBAT BLAST DISEASE (Magnaporthe oryzae L.)
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2016-08-20) AMRUTA, N; Narayanaswamy, S
    A study was conducted in the laboratory, greenhouse and field to know the influence of bio-priming on paddy seeds against blast disease at GKVK, Bengaluru and VC, Farm Mandya. The total 60 bacterial strains were isolated from paddy rhizosphere and used for in vitro and in vivo evaluation against M. oryzae along with two reference strains B. subtilis and P. fluorescens and eleven bacterial strains showed maximum inhibition. Thirteen strains were characterized as bacteria belong to genera Bacillus, pseudomonas, Serratia, Alcaligenes and Proteus using 16S rRNA sequencing. The bacterial isolates exhibited antagonist property showed the presence of antimicrobial peptide genes. In vitro evaluation revealed that the B. amyloliquefaciens UASBR9 and Serratia marcescens UASBR4 found most effective against the pathogen (84.14 and 76.83 per cent respectively) compared to reference cultures RBs-1 (72.00 %) and RPf-1 (55.24 %). The least PDI and highest germination was recorded in HR-12 seeds bioprimed with UASBR9 (0.69 and 99.00 %) compared to untreated control (3.43 and 95.00 %) under in vivo condition. Seeds bio-primed with formulated product of UASBR9 and talc+MgSO4 @10g/kg seed was recorded least PDI (6.63 %), highest seed yield/plot (0.68 kg) and maximum germination (99.50 %) compared to untreated control (20.25 %, 0.27 kg and 90.00 %, respectively). Seed bio-primed with UASBR9 showed induced systemic resistance in rice on challenge inoculation with M. oryzae and increased activities of peroxidase (0.563 min-1 gram-1), PPO (0.825 min-1 gram-1) and PAL (6.849 nmol t-CA) and defense-related enzymes response against pathogen compared to untreated control.

    SEED PRODUCTION AND STORAGE TECHNIQUE IN FIELD BEAN (Lablab purpureus L. Sweet.)
    (University of Agricultural Sciences GKVK, Bangalore, 2014-10-12) VENUGOPALA, N. G.; Rama Prasanna, K. P.
    Study were carried out to know the effect of spacing & fertilizer levels and the effect of flower thinning and position in Hebbal avare-3 on seed yield and quality. Seed storability was studied by using Hebbal avare-3, local avare black and local avare white dressed with seed chemicals and red earth and stored in cloth and polythene (700 gauge) bag for 16 months. Wider spacing 45x30 cm gave higher seed yield/plant (16.81 and 16.67 g), hundred seed weight (25.52 and 22.50 g), germination (91.22 and 91.11%), seedling vigour index (12,255 and 10,868) and higher seed germination (61.12 and 57.81 %) during AA (7 days) and narrow spacing 30x15 cm recorded more plant height (40.88 and 40.17 cm) and seed yield (8.76 and 8.31 q/ha) followed by 45x15 cm. Higher fertilizer level 37.5:75:37.5 kg NPK/ha + 375 g/kg Rhizobium resulted maximum seed yield/plant (15.02 and 14.89 g), hundred seed weight (23.72 and 22.37 g), seed yield (7.52 and 7.44 q/ha), germination (90.00 and 92.89 %) and seedling Vigour index (9,893 and 10,306) during Kharif and Rabi summer, respectively. Removal of 50 per cent of top flowers recorded higher number of pods/plant (23.75 and 23.65), seed yield / plant (19.87 and 19.00 g), seed yield (8.30 and 8.05 q/ha), hundred seed weight (23.63 and 23.58 g), germination (97.00 and 96.00 %), seedling vigour Index (12,707 and 11,616) during kharif and Rabi summer, respectively. Local avare white when treated with thiram @ 2 g kg-1 + bavistin @ 2 g kg-1 and stored in polythene bag (700 guage) recorded higher germination (84.00 %) and seeds in cloth bag gave lower germination (76.00 %) followed by local avare black and Hebbal avare-3 at the end of 16 months of storage.
