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 SHELF LIFE EXTENSION OF SOLO PAPAYA (Carica papaya. L) FRUIT
    (University of Agricultural Sciences GKVK, Bangalore, 2008-07-20) RAVI, H. N.; Eshwarappa, H.
    An experiment was conducted in the laboratories of AICRP on Post Harvest Technology, UAS, GKVK, Bangalore, during the year 2007-2008. The experiment was carried out to find the effect of different packages and storage temperatures for enhancing shelf life of Solo papaya fruits. Many methods are available for fruit storage such as cold storage, controlled atmosphere storage, evaporative cooling systems etc. Recently, modified atmosphere (MA) storage is getting more popular for its desirable effects. The principle is extending the storage life by altering the storage atmosphere around the commodity and slowing down the metabolic ripening processes without affecting the quality of the commodity. Recently long term storage of vegetables has been achieved by using silicone membrane systems (Gairepy et al., 1998; 1986 Raghavan et al., 1982). It is desirable to try and see whether the Solo papaya fruits can be stored beneficially in the modified atmosphere created by the silicone membrane and diffusion channel systems. Fruits were packed in two different packages like silicone membrane with different window areas in airtight PET jars and diffusion channel system with different lengths and diameters in PET jars at ambient temperature for evaluation. PLW and gas composition inside the package were determined and then quality parameters were estimated immediately after removing from MAP. Finally best two packages each from, silicone membrane system and diffusion channel system were selected and fruits in these packages were stored in two different temperatures (Ambient, and 15oC) to find the effect of different packages and storage temperatures for enhancing shelf-life. The shelf life of Solo papaya fruits under ambient and refrigeration temperature in case of silicone membrane and diffusion channel systems it was 25 days compared to control which could be kept well for only 7 days under ambient temperature.
