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 VARIETAL CHARACTERIZATION, FORTIFICATION ON SEED YIELD, QUALITY AND LONGEVITY IN PIGEONPEA [Cajanus cajan (L.) Millsp.]
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-01-17) NAGARAJ, HULLUR; Channakeshava, B. C.
    The field and laboratory experiments were carried out to study the characterization of cultivars, seed fortification and longevity in pigeonpea during kharif 2014 and 2015. Twenty pigeonpea cultivars selected for characterization study and significant differences were observed for various morphological traits. Mottled seed colour pattern distinguished BRG-1 and BRG-3 cultivars from all cultivars having uniform pattern. Dens pattern of streak on standard petal differentiated the cultivar TS 3R from all the cultivars. Similarly, sesame kind of leaf shape differentiated cultivar JKM-189 from all the cultivars. Based on total soluble proteins zymogram, Region A (> 97.4 KD), B (66.0-97.4 KD), D (29.0-43.0 KD) and E (20.0 to 29.0 KD) were found useful to distinguish most pigeionpea cultivars. Among 12 SSR markers used to differentiate the cultivars, four markers viz., CCB-8, CCB-9. PB-3 and PB-8 were found highly polymorphic. The experiment on seed fortification with ZnSO4 @ 250 mg / kg + Borax @ 100 mg / kg of seed recorded higher plant growth, seed yield and quality attributes viz., plant height at 40, 80 DAS and at harvest (59.2, 118.0 and 191.8 cm, respectively), seed yield (1355 kg / ha), seed germination (89 %), seedling vigour index-I and II (3217 and 997, respectively), and low electrical conductivity of seed leachate (158 μS ppm-1) as compare to control. BRG-2 and ICP8863 seeds treated with spinosad 45 SC (2 ppm) and stored in super grain bag recorded higher germination (91 and 87 %, respectively) and other seed quality attributes as compare to untreated seeds stored in cloth bag (58 and 76 %, respectively) at the end of 12 months of storage. Whereas the seed amelioration treatments such as GA3 (400 ppm) and IAA + NAA (150 ppm each) are the suitable amelioration treatments to improve germination and vigour of aged and marginal quality pigeonpea seed lots.
