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 POMEGRANATE (Punica granatum L.)
    (University of Agricultural Sciences, Bangalore, 15-07-09) VEERDHAVAL ANANDRAO, JADHAV; Eshwarappa, H.
    Pomegranate (Punica granatum L.) is the fruit crop which belongs to a family Punicaceae which includes only one genus and two species, the other one little-known, being P. protopunica peculiar to the island of Socotra. It is one of the most favourite table fruits and also one of the hardiest fruit plants that thrives well under arid and semi arid climatic conditions. Transpiration losses in pomegranate limit their storage life and marketability. The shelf life of pomegranate is ten days only in ambient storage. This study was geared towards assessing the suitability of the Modified Atmosphere (MA) storage to extend the shelf-life of pomegranate fruit. The respiratory behaviour of pomegranate was studied in sealed glass chambers (replicated thrice) stored at two temperatures-ambient (25-27O C) and 10O C. The peak respiration rate of pomegranate was found as 44.6 mgCO2kg-1h-1 and 15.03 mgCO2kg-1h-1 at ambient and 10O C, respectively. Fruits were packed in three types of packages-200 gauge HDPE, 300 gauge HDPE with different ventilations and silicone membrane system with different window areas in airtight PET jars and stored at two temperatures (ambient and 10O C) to find different packages and storage systems for enhancing shelf-life. Gas composition, PLW and microbial growth inside the storage environments (packages) were determined and the quality parameters were estimated immediately after removing from MAP. With the passive gas modification, pomegranate was stored in ambient storage for 10 days whereas in modified atmosphere packaging (200 gauge HDPE, 300 gauge HDPE and silicone membrane system), the shelf-life of pomegranate fruits was extended up to 60, 60, 25 days at ambient and 96, 96, 65 days at 10O C temperature respectively. With regard to the entire sensory and quality parameters, HDPE package was found to be better than silicon membrane system.
