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 PADDY STUBBLE BIOCHAR ON GROWTH AND YIELD OF FIELD BEAN
    (University of Agricultural Sciences, Bangalore, 2022-12-08) CHANDRIKA, K; Rinku Verma
    A packet experiment was conducted in University of Agricultural Sciences,GKVK, Bangalore to study the effect of paddy stubble biochar on growth and yield offield bean during 2021-2022. The experiment included 24 treatments and 2 replications.The results revealed that application of 25 t ha-1 biochar+farm yardmanure+vermicompost+ghanjeevamruth (T21) recorded higher growth parameters vizplant height(61 cm), number of branches(11), number of leaves (38) and the yieldattributes like number of pods (18 g), pod weight (17 g), biomass yield and pod yield offield bean. Growth indices such as specific leaf area, specific leaf weight and netassimilation rate did not vary significantly. The soil plant analysis development valuessignificantly varied at reproductive growth phase, however carbon dioxide assimilationand stomatal conductivity did not vary due to application of biochar. Application of biochar along with organic amendments recorded significant improvement in waterholding capacity (42%) and bulk density of the soil. The soil pH (8.6), electricalconductivity (0.20 d sm-1), organic carbon (0.53%), primary nutrients and secondarynutrients values increased significantly, however decrease in the mronutrient status ofpost-harvest soil was noticed. There was significant increase in uptake of major,secondary nutrients and micronutrient. Plant nutrient concentration and total nutrientuptake increased in treatment T20 that received 20 t ha-1 biochar+ farm yardmanure+vermicompost+ghanjeevamruth.
