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.

    STUDY AND OPTIMIZATION OF OPERATIONAL PARAMETERS OF AUTOMATIC CASHEW SHELLER FOR IMPROVED SHELLING
    (University of Agricultural Sciences GKVK, Bangalore, 11-08-12) ARUN KUMAR, H S; RAMACHANDRA, M
    Cashew (Anacardium occidentale L.) is a tropical tree which provides a kidney shaped nut called as “cashew nut” that is consumed all over the world. Cashew nuts are nutritious and tasty. The shelling of nuts is a laborious process mostly done in rural areas of Kerala, Maharashatra and Karnataka. The manual shelling process is tedious, time consuming and labour intensive. To address this, different pretreatments were conducted on raw cashew nuts and the performance of an automatic cashew nut sheller was evaluated. Studies were conducted to determine the physical properties and the effect of pre-treatments on the shelling of the cashew nuts. The nuts were graded as small, medium and ungraded. The pre-treatments consisted of steaming the nuts at different pressures (0.0, 1.0, 1.5, 2.0 and 2.5 kg/cm2) for different durations (15, 20, 25, 30 and 35 min). The results indicated that lower cutting force is required for shelling the pre-treated nuts compared to the raw nuts. The shelling efficiency was found to be highest (80.66%) in ungraded nuts for a pre-treatment of 1.5 kg/cm2 pressure for 30 minutes. The whole kernel recovery was highest (96.21%) in medium nuts for a pre-treatment of 0.0 kg/cm2 pressure for 25 minutes. The Cost-benefit ratio was found to be 1:1.57 for the Automatic Cashew Sheller.
