the present research was conducted to study the effect of irrigation treatments on growth indices, yield, and water use efficiency of long green pepper (capsicum annuum l.) at the research greenhouse of shahrekord university. this experiment was done in a clay-loam soil using randomized design with four treatments i.e. 40%, 60%, 80%, and 100 percent of water requirement and three replications, ...

As the water requirement for food production and other human needs grows, quantification of environmental flow requirements (EFRs) is necessary to assess the amount of water needed to sustain freshwater ecosystems. EFRs are the result of the quantification of water necessary to sustain the riverine ecosystem, which is calculated from the mean of an environmental flow (EF) method. In this study,...
