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.

    IMPACT OF WEATHER PARAMETERS ON PRODUCTIVITY OF SELECTED CROPS IN MANDYA DISTRICT- A STATISTICAL APPROACH LAKSHMI, L. N. PALB 2167

    The present study attempts to know the trend of selected weather parameters and to analyse the impact of weather parameters on productivity of ragi and sugarcane in Mandya district. The secondary data of weather parameters for the study was obtained from ZARS, V. C. Farm, Mandya for the period from 1986 to 2010. Further, the available data of crop productivity was obtained for the period from 1991-2010 (25 years). The parameters consider viz., maximum temperature, minimum temperature, relative humidity, cloudiness, wind speed, sun shine hour, rainfall and ragi and sugarcane yield for the study. The trend analysis revealed that the maximum temperature showed a positive significant trend whereas relative humidity and rainfall showed a positive non significant trend over a period of time for most of the months. The cloudiness and sun shine hour showing a negative significant trend whereas minimum temperature and wind speed shown a negative non significant trend during study period for most of the months. The correlation analysis indicated that the productivity of ragi and sugarcane was positively correlated with average minimum temperature, wind speed and rainfall, however negatively correlated with maximum temperature and relative humidity. The sun shine hour contribution was higher (75.97%) towards the productivity of ragi, followed by wind speed (27.33%), cloudiness (14.67%), and rainfall (7.76%). The lowest contribution was minimum temperature (0.35%) and relative humidity (0.87%). Whereas productivity of sugarcane the maximum temperature contribution was higher (23.42%), followed by relative humidity (15.15%), minimum temperature (13.33%). The lowest contribution was sun shine hour (0.75%), followed by cloudiness (1.05%) and wind speed (1.22%).
