Experiments were conducted using a randomized completely block design with three replications in eight environments. Results indicated that environment （E）, genotype （G） and genotype x environment interaction （GE） significantly affected Fe concentration in rice grains. Environment explained 74.43 % of total （G＋E＋GE） variation, whereas G and GE captured 5.60% and 19.67%, respectively. Rice genotype Barumun was desirable in terms of the highest ability and stability for Fe concentration in rice grains. Environment in genotype Cilongok was the best representative of the overall environments and the most powerful to discriminate rice genotypes.展开更多

Social resilience is the key to achieve risk reduction measures at the local levels. The objective of the paper is to assess the community resilience of the three disaster prone districts in Balochistan. A sample of 399 households was selected using stratified sampling with proportional allocation method. Four components of community resilience were assessed. The results reveal that in all components of resilience district Ziarat was more resilient compared with other two districts followed by district Jaffarabad and Nushki. The article recommends that certain initiatives may be take in the other districts also to enhance the community resilience to different disasters particularly by conducting awareness complains, diversification of income sources, and physical structure to various natural hazards.展开更多
