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 TREATED SEWAGE WATER ON MULBERRY PRODUCTION AND ITS IMPACT ON COCOON QUALITY
    (University of Agricultural Sciences, Bangalore, 2020-12-04) ARUN KUMAR, M; CHANDRASHEKAR, S
    The research entitled “Effect of treated sewage water on mulberry production and its impact on cocoon quality” was conducted at Department of Sericulture, UAS, Bangalore during Rabi 2019. There were six treatment combinations comprising of raw sewage water, treated sewage water and borewell water replicated four times and laid out in randomized complete block design. Results of the research revealed that soil nutrients, mulberry growth, leaf yield, leaf quality parameters and silkworm growth and cocoon parameters were found significantly influenced by raw and treated sewage water irrigation. Among different treatment combinations 100% raw sewage water irrigation recorded higher growth, leaf yield (54319 kg ha-1 year-1) and quality parameters such as leaf NPK (3.68% N, 0.40% P and 1.91% K) and micronutrients (30.08 ppm of Zn, 103.75 ppm of Mn and 373.75 ppm of Fe) compared to 100% treated sewage water and borewell water irrigation. Silkworms fed with mulberry leaves from the plot irrigated with 100% raw sewage water showed significantly higher larval weight (32.02 g/10 larvae), single cocoon weight (1.706 g), single shell weight (0.321 g) and cocoon shell ratio (18.65 %) whereas, higher Effective Rate of Rearing (99%) was noticed in 100% treated sewage water irrigation. Similarly, soil EC, OC, N, P, K, Fe, Mn, Zn were significantly higher in 100% raw sewage water irrigated plot. An overview of the study revealed that raw sewage water irrigated plot significantly improved the soil fertility status and growth of mulberry as well as silkworm growth and cocoon parameters.
