Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Impact analysis of seasonal climatic variability on rice productivity in eastern agroclimatic zone of Haryana
    (CCSHAU, 2010) Bemal, Suchandan; Diwan Singh
    The present study “Impact analysis of seasonal climatic variability on rice productivity in eastern agroclimatic zone of Haryana” was undertaken to work out the climatic variability and trends at locations namely Ambala and Karnal and to have an idea of the probable impact of future trend scenarios for productivity of rice in eastern agroclimatic zone (main rice growing region of Haryana) using CERES-Rice model. Historical data (1977-2008) on weather and rice productivity for above two locations were collected. Analysis showed that maximum and minimum temperature variability has considerably increased during the period from 1997-2008 and that more so during winter season at both locations. The study revealed increase in rainfall during the south west monsoon season and increased variability in post monsoon rainfall at the both locations. Highest seasonal and monthly variability of solar radiation was observed in winter season and month of January, respectively at Ambala. The trend study for annual maximum temperature indicated an increase at Ambala while a decrease at Karnal. However as of recent past (1997-2008) the trend has reversed and indicated an increase of maximum temperature at both the places. The seasonal trends of maximum temperature at Ambala showed an increase during summer, south-west and post-monsoon seasons but decrease during winter. On the other hand at Karnal, a decreasing trend was observed during kharif and winter. Annual and seasonal (except summer) minimum temperature trend revealed a decrease at Ambala. The annual rainfall at Ambala showed an increasing trend but reverse trend was noted at Karnal. Annual Solar radiation trend was decreasing at the rate of 0.04 and 0.07 MJ/m2 at Ambala and Karnal, respectively. At Ambala, the maximum temperature and rainfall trend was increasing but at Karnal both the parameters showed decreasing trend during kharif seasons of 1977-2008. The kharif season rainfall variability was of greater proportion at Karnal than at Ambala. CERES-Rice model simulations with increase in maximum temperature of upto 1ºC above normal resulted in positive effect on rice productivity, However, the increase in minimum temperature event by 0.5ºC above normal caused loss in productivity at both the places. Further, the model projected a decrease of 19.0 and 16.9% in rice grain yield with increase of both maximum and minimum temperatures by 2.5°C above normal at Ambala and Karnal, respectively. The increase of either maximum or minimum temperature (upto 1°C) in conjunction with increment of carbon-dioxide concentration in atmosphere (upto 100 ppm) resulted in increase of rice productivity at both the locations. The rice grain yield simulations by CERES-Rice model with different temperature increments (either of maximum/minimum or combinations of two) accompanied by different CO2 concentrations suggested that the negative effect of incremental temperatures on rice productivity got marginalized with progressive increments of CO2 concentrations. The rainfall and solar radiation had positive relationship with rice productivity at both locations.
