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.

    SUITABILITY OF BIOFUEL CROP RESIDUES AS POTENTIAL SOIL AMENDMENT- A CRITICAL STUDY
    (UNIVERSITY OF AGRICULTURAL SCIENCES, GKVK BENGALURU, 2019-03-18) RISING PANMEI; PRASANNA, K. T.
    A study was conducted to determine the suitability of biofuel crop residues as potential soil amendment. During the composting of leaf litter, fruit husk and oil cake of Pongamia pinnata and Simarouba glauca, it was observed that the temperature in all the compost piles ranged from 24.4􀔨 to 50.5􀔨. EC values of the compost were within the threshold value of <4.0 dS m-1 (FCO, 2013) and their pH ranged from 6.0 to 8.5 at 90 days. The bacteria, fungi, actinomycetes, and N2-fixers were found in good numbers during the maturation phase. There was also net decrease in enzyme activities in all the treatments at the end of 90 days. Thus, these results suggested that the biofuel crop residues have been converted to stable compost in 90 days. The study was taken forward to assess the effects of raw and composted biofuel crop residues on the physiology and growth efficiency, and yield of maize; and soil health properties. It was observed that the biofuel crop residues regardless of their forms as raw or composted at 10 t ha-1 produced higher growth and yield compared to the recommended dose of farmyard manure or NPK fertilizers. The incorporation of biofuel crop residues has shown diverse responses at various stages of observation. This may be due to the influence on soil physical properties as well as the microbial population that might have influenced better availability and uptake of nutrients. Either raw or composted biofuel residues can be applied as soil organic amendment at the rate of 10 t ha-1 serving as an important component of sustainable agriculture.
