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.

    Feeding potential of Tyrophagus putrescentiae Schrank (Acari: Acaridae) and its management
    (CCSHAU, 2010) Anita; Gulati, Rachna
    The studies on mean population of T. putrescentiae, percent weight loss and damage caused to grains qualitatively revealed that none of the grains was completely immune to pest infestation, however their susceptibility varied significantly (p=0.05).Susceptibility of grains/ flakes increased significantly with increase in initial infestation level and duration of infestation. Among the four foods, oat flakes was found significantly more susceptible (CD = 7.87; p = 0.05) as more number of mites (240.73 mites/5g grain) was recorded than on green gram flakes (207.26 mites/5g grain) and whole grains of oats (186 mites/5g grain). Least number of mites (173.26 mites/5g grain) was recorded from whole grains of green gram. The weight loss in oat flakes was 148.49mg/ 5g followed by loss in green gram flakes (121.40 mg/ 5g), oat grains (99.65mg/ 5g) and green gram grains (92.02 mg/ 5g) at pre count of 60 mites. Highly significant positive correlation (r= 0.93 to 0.99) was recorded at 15, 30 and 45 days between T. putrescentiae population and weight loss in oat grains. Qualitative estimation of oat flakes revealed the losses in protein contents (0.4 to 1.22%), total soluble sugars (0.5 to 1.35%), starch (0.24 to 1.38%) and non reducing sugars (3.49 to 9.97%) after 45 days of infestation. However, the reducing sugars exhibited a marked increase from 1.9 g/100 g (control) to 2.72 g/100 g flakes at 45 days of mite exposure when subjected to initial count of 20 mites/ 5g flakes. Aqueous extracts of Ocimum sanctum leaves and Glycyrrhiza glabra stems showed concentration dependent activity against T. putrescentiae in oat flakes. Among the extracts, G. glabra was effective as it provided 71.53 to 94.75 percent relative protection against T. putrescentiae whereas, O. sanctum extract caused 66 to 92 percent reductions in number at different durations.

    Social problem-solving skills of 6 to 8 years old children in relation to intelligence quotient
    (CCSHAU, 2010) Anita; Balda, Shanti
    The present study was conducted in Kaimri village of Hisar Block 1 of Hisar district. There were two government schools in Kaimri village, one for boys and one for girls. From these two schools, 94 boys and 85 girls in the age range of 6-8 years were assessed for their IQ with the help of Stanford-Binet Intelligence Scale (1973). Children were divided into low, average and high IQ categories. Ninety children including 45 boys and 45 girls, 15 boys and 15 girls from each IQ group were selected. The objectives of the study were - first, to identify low, average and high IQ children in the age group of 6 to 8 years; second, to assess social-problem solving skills of low, average and high IQ children; third, to compare social-problem solving skills of low, average and high IQ children and fourth, to delineate the factors related to social-problem solving skills of children. Social problem-solving skills of selected children were assessed with the help of Social Problem-Solving Test (Rubin, 1988). Responses of the children were examined quantitatively and qualitatively. Quantitative scores were calculated for total number of categories, number of different categories, relevancy and flexibility. Quality of responses included strategies suggested by children to solve problems in hypothetical situations with their peers. Results revealed that majority of children belonged to average category of IQ. IQ had significant impact on social problem-solving skills of children. Other factors related to social problem-solving skills of children were age and gender of child; paternal education and occupation and family income. Behavioural aspects, aggression, emotionality and impatience had significant relationship with social problem-solving skills. Research further revealed that, most frequently used strategies by children were “non-forceful” in nature. Gender differences indicated that girls suggested greater number of “non-forceful” strategies than boys who suggested greater number of “forceful” strategies.
