    Opis:
    This study was carried out to assess the extent of genetic variability for yield and yield related traits and to estimkate heritability and genetic advance in rainfed upland rice genotypes Twenty-two selected upland rice varieties were evaluated in randomized complete block design with three replications during 2014 cropping season. The analysis of variance showed highly significant differences (p < 0.01) for days to flowering, days to maturity, hundred seed weight, plant height and panicle length and differed significantly (p < 0.05) for fertile tiller per plant, filled grains per panicle, unfilled grains per panicle ,biomass yield and grain yield per plot except harvest index, indicating the existence of variability. The higher phenotypic and genotypic variance were obtained from number of filled grains, plant height, days for 50% heading, days for 85% maturity and biomass yield indicating high influence of the environment on the traits. The high level of genotypic and phenotypic coefficients of variation was recorded for traits like biomass yield, grain yield, number of fertile tillers per plant and unfilled grains per panicle. Heritability estimates were moderately high for days to maturity (66.01%), and thousand-grain weight (66.80%). High genetic advance as percent of means was observed for biomass yield per plot, unfilled grains per panicle, grain yield per plot, and fertile tiller per plant. Thousand-grain weight showed moderately high heritability coupled with high genetic advance as percent of mean. Therefore, selection based on this character might be effective for increasing grain yield.

    Opis:
    This study examined the effect of corporate social responsibility on organizational performance in Guinness Nigeria Plc, Benin City using survey research method. A sample of 312 respondents was drawn from the 857 employees using accidental sampling technique. Data collected were analyzed using correlation and regression analysis. The results of the study revealed that there is a positive and significant relationship between corporate social responsibility and organizational performance. The results also showed that corporate social responsibility do have a significant effect on organizational performance in Guinness Nigeria Plc, Benin City. Thus, this study recommends among others that the management of Guinness Nigeria Plc should make effort to sustained and improved social responsibility activities such as community projects and environmental protection in order to enhance peaceful and cordial relationship with inhabitants and achieved maximum organizational performance and competitive advantage.

    Opis:
    Field investigation was carried out to study the genetic variability, heritability and genetic advance and the variability studies showed significant differences among the thirty genotypes for all the thirteen characters. Yield per plant was maximum in CL 4 genotype collected from Atchirupakkam in Villupuram district. The characters viz., number of vines per plant, sex ratio, days to first female flowers, node number of first female flower, days to fruit maturity and number of fruits per plant were recorded the maximum in the same genotype. Genetic analysis indicated maximum phenotypic and genotypic coefficient of variation for single fruit weight and 100 seed weight. The characters viz., fruits diameter, flesh thickness, number of fruits per plant and yield per plant, recorded highest estimate of PCV and moderate estimation of GCV. The characters viz., number of seeds per fruits, flesh thickness, number of primary branches and fruit diameter recorded moderate estimate of PCV and GCV. Lower estimation of GCV was observed for sex ratio, fruit length and number of male and female flowers. High heritability (broad sense) was observed for 100 seed weight, number of seeds per fruit, single fruit weight, vine length, fruit diameter, fruit length, flesh thickness, number of male flowers,sex ratio, yield per plant, number of primary branches per plant, number of female flowers and number of fruits per plant. Based on mean performance, CL 4 followed by CL 22 and CL 10 were selected as the best genotypes in watermelon for the costal ecosystem, by virtue of their higher yield combined with desirable component characters.
