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.

    WEATHER BASED FORECASTING MODELS FOR SUGARCANE CROP YIELD IN SELECTED DISTRICTS OF KARNATAKA
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BENGALURU, 2018-08-02) ABHINANDAN, A. CHOUGALA; Krishnamurthy, K. N.
    In the present study, a prudent attempt has been made using data from 1985 to 2016, to understand the trend in area and production of sugarcane in selected districts of Karnataka. Further, an attempt is also made to forecast the yield of sugarcane and to assess the impact of climate change on yield of sugarcane crop. The regression models were fitted for the trend in area and production. Based on the model adequacy, linear model was the best fit for area of sugarcane in Belagavi and Vijayapura districts and linear model was found to be best fit for production of sugarcane in Belagavi and Dharwad districts also. Further, cubic and quartic models were found to be best fit for area and production of sugarcane in Dharwad and Vijayapura districts respectively. Due to the presence of autocorrelation in yield of sugarcane, Holt’s method, ARIMA and ARIMAX were used for forecasting. ARIMA(1,1,1), ARIMA(0,1,0) and ARIMA(0,2,0) were found to be the bestfitted models based on MAPE, RMSE and BIC values for forecasting sugarcane yield in Belagavi, Dharwad and Vijayapura districts respectively. Stepwise regression method was used to know the impact of climate change on yield of sugarcane in selected districts of Karnataka. This study indicated that rainfall, minimum temperature and relative humidity were having statistically significant impact on sugarcane yield in Belagavi, Dharwad and Vijayapura districts respectively. Thus, we can conclude that there is different impact between the above mentioned climatic factors and sugarcane yield in three districts.
