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.

    ASSESSMENT OF ORCHARD CROP YIELD UNDER DIFFERENT SOIL AND WATER CONSERVATION MEASURES BY ANALYZING DIFFERENT VEGETATION INDICES THROUGH UNMANNED AERIAL VEHICLE
    (University of Agricultural Sciences, Bangalore, 2020-12-04) AKASHA DEEPA, P U; RAVIKUMAR, B C
    In order to assess crop yield at different soil moisture levels the present study was conducted with soil moisture conservation structures like crescent bundin GKVK campus, UAS, at northern part of Bengaluru city located in the southeast of the South Indian state of Karnataka. Crop yield and soil moisture relations for Sapota (Chikoo) trees under crescent bunds and control condition were compared using different vegetation indices by remote sensing image processing techniques. Both the lab and field methods were used to determine soil moisture status at depth of 0-15 cm, 15-30 cm and 30-45 cm from the soil surface and at a distance of 30 cm, 60cm and 90 cm from the tree trunkrespectively. The results were statistically analyzed using Paired T-test and Pearson’s correlation analysis which showed that the difference in soil moisture between the two treatments was significant and also showed that there exists a linear relationship with a strong correlation in between soil moisture and the yield by having the Pearson coefficient in both the conditions nearly equal to 1. The spectral signatures developed revealed that the trees under the control condition were under water stress compared to trees under the crescent bunds. The study revealed that by adopting the crescent bunds in the fields helps in conserving the soil moisture which contributes to the yield in case of rainfed agriculture. The study also shows that the VARI serves as an effective tool in determining the crop under water stress.
