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.

    INFLUENCE OF PRE-EMERGENCE HERBICIDE MIXTURES ON GROWTH AND YIELD OF POTATO (Solanum tuberosum L.)
    (University of Agricultural Sciences, Bangalore, 2021-12-01) NAGARAJ CHITRAGAR, R.; HANDRAPPA
    A field experiment was conducted to study the “Influence of pre-emergence herbicide mixtures on growth and yield of potato (Solanum tuberosum L.)” at ICAR Krishi Vigyana Kendra, Hadonahalli, Doddaballapura Taluk, Bengaluru Rural District during kharif 2020. The results revealed that lower total number of weeds (7.67 m-2) and weed dry weight (11.75g m-2) was observed with metribuzin 11.25% + pendimethalin 29.75% ZC @ 2500 ml ha-1 which was at par with twice hand weeded plot (5.56 m-2 and 9.71g m-2 weeds and weeds dry weight respectively). Higher weed control efficiency (93.55%), taller plants (70.15 cm), plant spread (NS: 55.08 cm and E-W: 60.46 cm), maximum number of leaves (37.61), leaf area (22.28 cm2), number of haulms per plant (2.73), umber of tubers per plant (6.78), weight of tubers per plant (593.9), higher TSS (5.6 °Brix), minimum number of days for 50 per cent flowering (29.33 days), tuber yield (34.21 t/ha), marketable yield (29.57 t/ha), maximum N, P and K uptake by potato plant (223.73, 16.91 and 271.79 kg/ha N, P and K respectively) and minimum uptake by weeds (8.27, 1.73 and 7.20 kg/ha N, P and K respectively) noticed with metribuzin 11.25% +pendimethalin 29.75% ZC at 2500 ml ha-1 which was on par with hand weeding @ 20 and 40 DAP. The higher B:C ratio (2.61) was noticed with metribuzin 11.25% + pendimethalin 29.75% ZC at 2500 ml ha-1 as compared to other treatments.
