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 POWER OPERATED DEHULLER FOR SUNFLOWER SEEDS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-08-14) BASAVARAJ S., GADIGEPPAGOL; Palanimuthu, V.
    Engineering properties of sunflower seeds and kernels were measured at moisture contents of 3, 5 and 7% (w.b.); values of all measured properties except bulk density increased with increase in moisture content. A prototype power operated (0.5 hp motor) Sunflower seed dehuller of 18 kg/h capacity was developed mainly for the use of confectionary industry. The dehuller consisted of feed hopper, cylinder-concave dehulling assembly, husk separation unit and V-belt pulley power transmission system. Dehulling trials were conducted in developed dehuller as per Box-Behenken Design under response surface methodology by varying feed rates (15, 18 and 21 kg/h) and cylinder speeds (250, 350 and 450 rpm) using sunflower seeds of three moisture contents (3, 5 and 7%). Best dehulling performance i.e., dehulling efficiency (93.8%), whole kernel recovery (85.1%) and kernel damage (4%) was observed at 18 kg/h feed rate with 350 rpm cylinder speed when sunflower seed moisture was 5%. Optimization of dehuller operating parameters was attempted using Design Expert software based on desirability function and the theoretically predicted optimum conditions were practically verified. Pre-treatments such as sun drying, dry and wet heat treatments were applied to sunflower seeds to improve dehulling characteristics and the dry heat pretreatment @70 ı for 20 min was found to be best. Storage study of dehulled kernels was conducted for two months by packing kernels in different packages (metallic tin, LDPE and HDPE) and storing at 4 and 30 °C temperatures. Biochemical analysis of kernels indicated that metallic tin was best for kernel storage.

    STUDIES ON CURING OF ONION (Allium cepa L.) BULBS IN MODULAR POLYHOUSE DRYER
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2017-07-10) PRASHANTAKUMAR; Eshwarappa, H.
    Onion (Allium cepa L.) is by far the most important of the bulbs across vegetable crops. It is popularly used both in immature and mature bulb stages as a vegetable (Homer and Williams, 1957). Onion originates from the region comprising of North West India, Afghanistan, Tajik and Uzbek. In India, onion is grown from very ancient time, as it is mentioned in Charaka-Samihita a famous early medical treatise. It has got a Sanskrit name ‘Palanduhu’ (Krishnamurthy et al., 1987). Onion grown for bulbs belongs to the family alliaceae and comes under genus Allium (Warade and Kadam, 1998). The outstanding characteristic of onion is its pungent alliaceous odour, owing to a volatile oil known as Allyl-propyl-disulphide (Saini, 1997). This character accounts in large part for its use as a food, a spice in cooking, a salad vegetable and certainly is the basis for their century old repute in medicines (Balasubramanyam et al., 1999).
