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.

    DEVELOPMENT OF A MOTORIZED GARLIC BULB BREAKER
    (2014-07-27) B B, CHANNABASAMMA; Carolin Rathinakumari
    Garlic (Allium sativum.) is one of the important bulb crops, used as a spice or condiment throughout India.The planting material for garlic cultivation is garlic cloves. The garlic cloves are separated from the whole bulb by beating with a wooden stick. This conventional method is very laborious and time consuming. To address this problem, a motorized garlic bulb breaker was developed and evaluated for its performance. The bulb breaking unit consisted of i) feed hopper, ii) bulb breaking unit (two stages of rollers), iii) blower, iv) outlets, v) main frame and vi) power transmission system. The breaker was evaluated at three levels of rubber padding material viz., plain, button and corrugated types, four levels of clearance between the rubber rollers viz., 15, 18, 21 and 24 mm, three levels of lower speeds viz., 25.92, 34.56, 43.2 m/min and three levels of higher speeds viz., 259.2, 302.4, 345.6 m/min. The motorized garlic bulb breaker with corrugated type padding material had the highest breaking efficiency, breaking capacity, germination at 18–21 mm clearance were 75 per cent, 404.56 kg/h, 100 per cent and 94.3 per cent, 782.18 kg/h, 100 per cent at a peripheral speed of 43.2 m/min for planting purpose and at a peripheral speed of 302.4 m/min for processing purpose respectively. The cost of developed breaker was .56, 000. Cost of breaking was .0.06/kg of garlic. The cost saved by machine over manual bulb breaking for planting purpose and for processing purpose was 90 and 96 per cent respectively.
