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.

    EVALUATION OF IMPROVED INTERCULTURAL EQUIPMENTS FOR SOIL MOISTURE CONSERVATION UNDER DRYLAND CONDITION OF SOUTHERN KARNATAKA
    (University of Agricultural Sciences, Bangalore, 2022-12-08) ADARSHA; MURUKANNAPPA
    A field experiment entitled “Evaluation of improved intercultural equipments for soil moisture conservation under dryland condition of Southern Karnataka” was conducted during Kharif 2021 at AICRP for Dryland Agriculture, GKVK, UAS, Bangalore. The experiment was laid out in RCB design and replicated thrice. The study consists of ten treatments viz., T1: Hand weeder with blade hoe, T2: Improved hand weeder with tyne hoe, T3: Hand weeder with furrow opener, T4: Cycle weeder with blade hoe, T5: Cycle weeder with tyne hoe, T6: Cycle weeder with Furrow opener, T7: Mini-tiller operated blade hoe, T8: Mini-tiller operated tyne hoe, T9: Mini-tiller operated furrow opener and T10: Control (Hand weeding) and the treatments were imposed 30 DAS. Among different treatments, weeding efficiency is higher in hand weeding (T10). The mini-tiller operated intercultural equipments helps in timely operation with higher field capacities and the maximum time saving varied from 78.79 to 81.57 per cent. However, the weeding efficiency is higher in hand weeding (T10). Treatment T9 recorded maximum average soil moisture, higher soil infiltration rate and better growth attributes, resulted in higher grain (2707 kg ha-1) and straw yield (3478 kg ha-1) as compared to T10. Treatment T9 also recorded higher gross returns of ₹ 86613 ha-1, net returns of ₹ 56722 ha-1and B:C ratio (2.90) as compared to other treatments. The least gross return of ₹ 64560 ha-1, net return of ₹ 29856 ha-1and 1.86 B:C ratio was found in control. Treatment T9 found to be best treatment under dryland conditions.
