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 of Intervention Programme on Thinking Skills of Institutionalized Adolescents
    (CCSHAU, 2015) Anita; Duhan, Krishna
    The present investigation was conducted purposively in Haryana and Delhi state. Two hundred adolescents, i.e., 100 boys and 100 girls in the age group of 13 to 19 years were selected randomly from the selected institute of Faridabad (Haryana) and institute of Bawana (Delhi). The thinking skills of adolescents were assessed by Life Skills Assessment Scale (LSAS) developed by Nair et.al (2010). Beck depression inventory (BDI-II) developed by Beck et.al (1966) was used to estimating depression among adolescents. Test anxiety scale (TAS) developed by Sharma (1978) was used to measure the anxiety level of adolescents. A life stress scale developed by Aggarwal and Naidu (1986) was used to study the level of stress among adolescents. After assessing the existing thinking skills, adolescents were further assigned to experimental group (50) and control group (50) from each Institute. Intervention package on thinking skills was developed and imparted to the experimental group adolescents. Results of the study highlighted that institutionalized adolescents had average level of thinking skills in all four dimensions i.e. problem solving, creative thinking, decision making and critical thinking skills. Age, gender and relationship with peers were found significantly associated with thinking skills among adolescents. Majority of adolescents had moderate level of depression, anxiety and stress and exhibited negative and significant correlation with all dimensions of thinking skills. Intervention program enhanced the thinking skills of institutionalized adolescents to a great extent. A significant improvement was found in the mean scores of adolescents after imparting intervention program. The study demands to get aware the parents, teachers and others who are concerned with adolescents to explore and enhance their thinking skills.

    Bacterial delignification of paddy straw
    (CCSHAU, 2015) Anita; Malik, Kamla
    India is the second largest producer of paddy in the world after China and produces 98 million ton of paddy with roughly 130 million ton of straw. Field burning is the major practice for removing paddy straw which results in nutrient losses, increases the air pollution and consequently affects public health. Lignin is one of the most abundant aromatic natural substances present in the biosphere. It is a polymer composed of phenylpropanoid units, associated with cellulose and hemicelluloses in plant cell. In biological treatment systems, a wide variety of microorganisms including fungi, actinomycetes and bacteria have been used in lignin biodegradation. Now a day, the ligninolytic bacteria gaining importance, because of wider tolerance of temperature, pH and oxygen limitation than fungi. In the present study, a total of 30 bacterial isolates were obtained from soil and different ecological niches. Out of these, 15 isolates were screened for ligninolytic activity on LB media containing dyes (aniline blue, phenol red and guaiacol).The zone index varied from 2.7 to 3.7 with bacterial isolate DS2 showing the maximum zone of clearance (3.7) on LB media containing aniline dye. Only eight bacterial isolates were selected for measuring the ligninolytic enzyme activity in MSM broth containing 1.0% lignin. The activity of laccase varied from 2.34 – 3.56 U/ml, manganese peroxidase (MnP) ranged from 1.48- 4.12 U/ml and lignin peroxidase (LiP) varied from 2.37- 5.99 U/ml. The bacterial isolate, LS1 had both the highest laccase (3.56 U/ml) as well as lignin peroxidase (5.99 U/ml) activity. However, maximum manganese peroxidase activity was observed in PS1 (4.12 U/ml). All bacterial isolates (except PS1) produced maximum lignin peroxidase enzymes activity as compared to other enzyme. Five selected ligninolytic bacterial isolates were used for the delignification of paddy straw with different conditions like temperatures (25, 30 and 35°C), pH (5.0, 6.0 and 7.0) and incubation period (7, 14 and 21 days) under stationary condition. Optimum temperature for delignification was found to be 30°C and pH 6.0 for DS2 and LS1 whereas pH 7.0 for CS3, CS4 and PS1) after 21 days of incubation. The maximum lignin reduction (32%) was observed by isolate DS2 followed by LS1 (30%), therefore, DS2 and LS1 were scored as best isolates for delignification of paddy straw.
