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.

    PERFORMANCE OF BIVOLTINE SEED CROP ON GRADED LEVEL OF NUTRIENTS IN TREE MULBERRY
    (University of Agricultural Sciences, Bangalore, 2023-04-02) ASHISH, S. KARUR; C. DORESWAMY
    “Performance of bivoltine seed crop on graded level of nutrients in tree mulberry” was carried out during 2022 in Krishi Vignana Kendra, Haradanahalli Farm Chamarajanagara to find out the right combination of nutrients required to attain maximum yield. The results revealed that, the plants applied with 40 T FYM/ha/yr + 125 % RDF + Foliar spray of POSHAN recorded higher number of shoots/plant (24.45), number of leaves/shoot (42), shoot length (214.52 cm), plant height (416.83 cm), yield/plant (2.64 kg), moisture percentage (76.80 percent), moisture retention capacity (93.30 per cent), crude protein (20.33 per cent), chlorophyll ‘a’ (1.57 mg/g), chlorophyll ‘b’ (1.03 mg/g) and total chlorophyll content (2.57 mg/g). Among FC1 and FC 2 silkworm breeds reared, FC 2 breed has performed better on application of 40 T FYM/ha/yr + 125 % RDF + Foliar spray of POSHAN. Significantly maximum larval weight (43.67 g/10 larvae), single cocoon weight (2.20 g), pupal weight (1.80 g), average filament length (1320.07 m) and filament weight (0.35g) were recorded. The plants applied with 20 T FYM/ha/yr + 125 % RDF + Foliar spray of POSHAN recorded highest cocoon shell ratio (26.50 per cent) and denier (3.35) in FC 2 breed. With regard to Grainage parameters, silkworms fed with the plants applied with 40 T FYM/ha/yr + 125 % RDF + Foliar spray of POSHAN recorded highest pupation rate (97.80 per cent), moth emergence percentage (94.27 per cent), fecundity (641.61 eggs) and hatchability (95.28 per cent). Maximum net returns (Rs. 3,31,542) and B:C ratio (3.59) was recorded in tree mulberry applied with 20 T FYM/ha/yr + 125 % RDF + Foliar spray of POSHAN.
