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.

    STUDIES ON MAHOGANY (Swietenia mahagoni (L.) Jacq) BASED AGROFORESTRY SYSTEM AND ITS NURSERY MANAGEMENT
    (University of Agricultural Sciences Bangalore, 2021-09-24) CHETHAN, H. C.; Nagarajaiah, C.
    The study entitled “Studies on Mahogany (Swietenia mahagoni (L.) Jacq) based agroforestry system and its nursery management” was carried out at Agroforestry unit, L block, ZARS, GKVK, Bengaluru during 2020-21. The main experiment consisted of ten treatments which were replicated three times under RCBD. In nursery experiment, nine seed treatments were replicated three times under CRD. The results showed that the seeds of Swietenia mahagoni pre-treated with the mixture of cow urine and water in the ratio of 1:1 and soaked for period of 12 hours has recorded significantly higher germination percentage (66.30%), germination rate (0.33), vigour index (2994), root to shoot length ratio (0.61), mean daily germination (0.74) and seedling length (88.82 cm). The accumulated litterfall for the study duration was recorded to be 5549 t ha-1 and the verage decomposition rate constant of Swietenia mahagoni leaf and rachis was found to be 0.23 month-1 and 0.14 k month-1, respectively. Carbon sequestration potential of Swietenia mahagoni was observed to be 206.95 t ha-1. Finger millet performed better under Swietenia mahagoni based agroforestry system, in terms of grain (1724 kg ha-1) and straw (2320 kg ha-1) yield. The reduction in grain yield of intercrops of cowpea, green gram, little millet, foxtail millet and finger millet over their sole crops was to the extent of 17.88, 9.26, 16.77, 12.65 and 7.16 per cent, respectively
