    Yield and quality of cotton genotypes as influenced by different sowing time
    (CCSHAU, 2018) Renu Bala; Shweta
    A field experiment entitled, “Yield and quality of cotton genotypes as influenced by different sowing time”, was conducted at the research area of the Cotton Section, CCS Haryana Agricultural University, Hisar, during the kharif season of 2017. This experiment comprised of four sowing times (1st fortnight of April, 2nd fortnight of April, 1st fortnight of May and 2nd fortnight of May) in main plots and three genotypes (RCH 650, H 1098i and HD 432) in sub-plots. Total thirty six treatment combinations were tested in split plot design with three replications. The crop sown on 2nd fortnight of April gave significantly higher seed cotton yield (4556 kg/ha) than the other three sowing times, it was mainly attributed to more plant height, dry matter production, leaf area index, no. of bolls/m2, no. of sympodial branch and boll weight. Sowing time have shown non-significant effect on fiber quality parameters such as micronaire value, fiber strength, span length and upper half mean length (UHML) because these parameters are genetically controlled and therefore less influenced by sowing time. Among the three genotypes, RCH 650 produced significantly higher seed cotton yield (4395 kg/ha) than the genotype H 1098i (3344 kg/ha) and HD 432 (2488 kg/ha). More dry matter production, leaf area index, no. of sympodial branch and boll weight might have accounted for the highest seed cotton yield of genotype RCH 650. The difference in seed cotton yield among the genotypes might be due to different genetic characteristics of these three cotton genotypes. Genotype RCH 650 has shown better fibre quality traits such as micronaire value (4.42 10-6g/inch), fiber strength (28.21 g/tex), span length (82.41 mm) and UHML (27.67 mm) than the genotypes H 1098i and HD 432. Genotype HD 432 produced higher seed cotton yield when sown on 1st fortnight of April and H1098i produced higher seed cotton yield during 1st fortnight of April and 2nd fortnight of April.

    Social and Emotional Skills of Institutionalized Adolescents: An Action Research
    (CCSHAU, 2014) Renu Bala; Sangwan, Sheela
    The present study was conducted purposively in two institutions each from Haryana State and Delhi. Adolescents equally representing both the sexes i.e. 50 girls and 50 boys were selected on random basis from both the institutions. Hence, a total of 200 adolescents constituted the sample for the study to assess the existing social and emotional skills.The adolescents were further assigned to experimental (50) and control (50) group. Life Skills Assessment Scale (LSAS) developed by Nair.et al. (2010) was used to assess the social and emotional skills among the adolescents. Beck et al. (1996) was used to estimating depression among adolescents. Test-Anxiety Scale (TAS) developed by Sharma (1978) was used to measure the level of anxiety among the adolescents. A Life Stress Scale developed by Agarwal and Naidu (1986) was used to study the level of stress among the adolescents. After assessing the existing social and emotional skills of adolescents, results showed that the performances of boys and girls adolescents on all six dimensions of social and emotional skills were found in average level. Age, gender relationship with peers and teachers were found significantly associated with social and emotional skills among adolescents. Majority of adolescents had moderate level of depression, anxiety and stress and significant and negatively correlated with most of the social and emotional skills dimensions. To a large extent intervention program enhanced the social and emotional skills of institutionalized adolescents. There were significant improvements in the mean scores of adolescents after giving intervention program. Age and gender wise significant improvement was found in all six dimensions of social and emotional skills.
