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.

    DESIGN AND DEVELOPMENT OF KITCHEN WASTE SHREDDER FOR COMPOST PRODUCTION
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2015-10-03) GURUDATTA, KHANDKE; Venkatachalapathy, K
    Kitchen waste is the food which is discarded or lost uneaten. Wastage occurs in all stages of food supply chain. House hold wastes are organic in nature and are mostly composted. The process of shredding includes reducing the particle size of kitchen waste which is done manually and used in waste management. To address this, manually operated kitchen waste shredder was developed and its performance was evaluated. The developed shredder was tested using different parameters such as rotational speed and feeding rate. Among the different cylinder liners used, the small iron bar with specified dimension was selected for the final fabrication of the shredder. Resulting in maximum shredding efficiency (96.24 %), capacity (46.8 kg/h) & size reduction efficiency (96.86 %) for vegetable waste. For fruit waste it was observed to be 94.70 %, 40.8 kg/h and 97.47 %, respectively and for mixed waste it was 92.86 %, 44.4 kg/h and 96.34 %, respectively. Shredded kitchen waste was composted. N, P, K values were estimated for 1st, 15th, 30th and 45th day. Nitrogen (N) content (percent) was found to be 0.227 (1st day), 0.306 (15th day), 0.340 (30th day) and 0.770 (45th day). Phosphorus (P) content (percent) was found to be on 0.116 (1st day), 0.119(15th day), 0.159 (30th day) and 0.175 (45th day). For Potassium (P) it was, 0.09 (1st day), 0.132 (15th day), 0.188 (30th day) and 0.378 (45th day). The estimated cost of the shredder was 5190 /– and the cost ratio was found to be 1:1.69.
