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.

    Effect of different levels of fertigation and growth regulators on growth, yield and quality of rose cultivars under polyhouse condition
    (University of Agricultural Sciences, Bengaluru, 2012-12-08) A. M, Rajesh; K. V, Jayaprasad
    Studies were conducted to investigate the effect of different levels of fertigation and growth regulators on growth, yield and quality of rose cultivars under polyhouse condition during 2010-2012 at Precision farming centre, Department of Horticulture, University of Agricultural Sciences, GKVK, Bangalore. The growth, yield and quality parameters like plant height (67.18 cm & 68.28 cm), number of primary branches per plant (4.93 & 5.32), days taken for emergence of first flower bud (33.07 days & 32.93 days), number of cut flowers per plant (14.21 & 14.01), shoot girth (0.72 cm & 1.00 cm), diameter of flower bud (3.18 cm & 3.13 cm), length of flower bud (3.86 cm & 3.51 cm), length of cut flower stalk (59.76 cm & 55.60 cm),vase life (8.14 days) and B:C ratio (1:1.65) were significantly superior in the treatment F2 (120 % fertigation) in the seasons 1 and 2 respectively. Among the growth regulators tested for growth, yield and quality, it was found that G2 (GA3 300 ppm) was significantly superior for the characters like plant height (69.21 cm & 68.28 cm), number of primary branches per plant (4.70 & 5.00), days taken for emergence of first flower bud (32.52 days & 34.17 days), number of cut flowers per plant (13.32 & 12.80), shoot girth (0.71 cm & 0.89 cm), diameter of flower bud (3.08 cm & 2.98 cm), length of flower bud (3.74 cm & 3.38 cm) and length of cut flower stalk (59.85 cm & 54.06 cm) in the seasons 1 and 2 respectively. However, the treatment G4 (Humic acid 0.4 %) influenced the vase life by reducing the loss of water to the extent (56.44 g) and increasing water uptake (33.79 g) and thereby prolonged the vase life for a period of (8.12 days) only in the first season of the experiment. Hence, the variety Grand Gala with 120 per cent fertigation combined with 300 ppm GA3 was the ideal combination to grow roses under protected cultivation compared to rest of the treatments.
