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.

    Geoinformatics for groundwater characterization − A case study
    (CCSHAU, 2014) Bhat, Mohammad Amin; Grewal, M.S.
    The block Gohana is part of Sonipat district which lies between 28º57' and 29 12' N latitude to 76º38' and 76º52' E longitude with total area of 36,448 hectares. To ascertain the quality of groundwater and its impact on physico-chemical properties soil, water samples were collected from all the villages of block and analysed by standard methods. Based on the results of water analysis, soil samples from eighteen sites were collected and analysed for their physico-chemical properties by standard procedures. This study was accomplished by employing Geoinformatics to delineate and estimate salt affected soils. Out of 2.41% of salt affected area, 1.13% is moderately salt affected and 1.28% is strongly salt affected. The pH, EC, SAR and RSC in groundwater ranged from 7.19 - 9.72, 0.29 -15.76 (dSm-1), 4.03 - 24.16 (mmol l-1)1/2 and 0 - 9.2(me l-1), respectively. The cations ( Na+, Ca2+, Mg2+, K+) and anions (Cl–, SO4 2–, HCO3 –, CO3 2– and NO3 –, F–) varied from 2.85 -114.6, 0.15 - 12, 0.45 - 36.2, 0.05 -0.99 (me l-1) and 0.8 - 115.4, 0.15 - 31.39, 0.5 - 12.4, 0-4.0 (me l-1) and 0.59 - 62.37, 0.08 - 1.52 ppm, respectively. As per the water quality classification criteria suggested by All India Coordinated Research Project (AICRP) on Management of Salt Affected Soils and Saline Water Use in Agriculture (1989), 23 samples were found to be of good quality, 8 marginally saline, 5 saline, 15 high SAR saline, 11 marginally alkali, 7 alkali and 12 highly alkali. Soil profiles were collected based on different categories of irrigation water. Most of the profiles were having salt developed due to the presence of salts in irrigation water. The highest and lowest values of cation exchange capacity, exchangeable sodium percentage, organic carbon and calcium carbonate of soils of block Gohana were 2.34, 22.19 cmol (p+) kg-1; 3.42, 72.26 percent; 0.09, 0.57 percent and 0.10, 7.00 percent, respectively. The highest and lowest values of electrical conductivity, pH and sodium adsorption ratio of soil saturation extract of soils of Gohana were 1.26, 15.82 (dSm-1), 7.06, 9.74 and 2.68, 36.85 (mmol l-1)1/2, respectively. Most of the soil profiles were low in fertility. Highest electrical conductivity and sodium adsorption ratio of saturation extract were observed in surface layers of the soil which gradually decreased with depth irrespective of texture and quality of irrigation water. After the analysis of soil and water, the Arc Map was used to create various thematic maps like pH, EC, SAR, RSC and ESP of the study area. These thematic maps were combined to prepare water and soil quality maps.
