“…The highest grain yield was produced when Giza 179 rice variety was fertilized with 5 t CRS ha -1 followed by 5 t RS ha -1 treatment without any significant differences. These findings are in line with those of Saha et al (2009) and Sarkar et al (2017) who stated that apply of rice straw in paddy soil improves organic C, N, and availability of P, K, and Si and results in producing more than one ton per hectar yield advantage. Also, a marked superiority was recorded in all potassium treatments against the control in respect of grain yield.…”

A field trial was performed in 2015 and 2016 rice seasons at the farm of Rice Research and Training Center, Sakha, Kafr El-Sheikh, Egypt to study the role of organic fertilizer i.e. compost rice straw 5 t ha -1 (CRS) and rice straw 5 t ha -1 (RS) plus control and potassium treatments namely 60 kg K 2 O ha -1 applied basally before planting (K1), 30 kg K 2 O ha -1 basally plus 2% potassium sulfate (K 2 SO 4 ) as foliar spray at panicle initiation (K2), 2% K 2 SO 4 as foliar spray at both panicle initiation (PI) and late booting (LB) periods (K3) plus control (K0) on the yield and its attributes as well as some of grain quality characters of Giza 179 rice variety. The experiment was laid out in a split-plot design with four replications. The organic fertilizer was allocated in the main plots while the sub-plots received potassium treatments. The studied characters were plant height, number of tillers, number of panicle hill -1 , panicle weight, panicle length, number of branches panicle -1 , number of filled grains panicle -1 and number of unfilled grains panicle -1 , 1000-grain weight, grain and straw yield and some grains quality characters i.e. hulling, milling and head rice percentage as well as available and uptake of potassium . The main results revealed that application of both compost rice straw (CRS) and rice straw (RS) gave the same greatest values of all the previous characters except panicle length which gave insignificant effect. Application of potassium fertilizer at the rate of 60 kg K 2 O ha -1 basally applied before planting (K1) or as foliar spray at the rate of 2% K 2 O at both panicle initiation (PI) and late booting (LB) produced the highest values of all the studied characters. As for the interaction between organic fertilizer and potassium treatments, results clarified that the combination of 5 t CRS ha -1 with each of 60 kg K 2 O ha -1 (K1) or 2% K 2 O as foliar spray at both PI and LB (K3) gave the same greatest values in number of panicles hill -1 , filled grains panicle -1 and grain yield, while panicle weight and straw yield reached to the maximum values when 5 t RS ha -1 was combined with K1 and K3. Hulling% reached the maximum value when treated with 5 t CRS ha -1 while both milling and head rice responded to 5 t RS ha -1 . Treatment of potassium applied as a foliar spray at both PI and LB (K3) produced the highest hulling and milling% while head rice% responded to K2 and K3. The combination of 5 t RS ha -1 with K1 or K3 gave the highest hulling and milling% while head rice reached the maximum value when each of CRS and RS was combined with each of K1, K2 and K3. Available K reached the maximum value at 30 days after transplanting. Availability of K was the highest under rice straw treatment followed by CRS. The uptake of K reached to the greatest value when either CRS or RS was combined with K1 treatment. It can be concluded that combination of 5 t CRS ha -1 with K3 (2% K 2 SO 4 as a foliar spray at both PI and LB) produced the greatest grain yield and saved about 40 kg K 2 O ha -1 . ...

“…For urban communities, how to describe hydrological cycle, artificial water and drainage process in a more detailed way? It is still necessary to combine prototype observations with the information provided by the physical model in a mathematical model, and develop the tools of urban water cycle research, to provide a powerful support tool for the study of urban water cycle [20][21][22][23][24][25].…”

a b s t r a c tUrban water cycle is one of the foremost contemporary research topics in hydrological research, and it forms the foundation of urban water resources management. This study serves to provide better analysis and understanding of the changes in urban water cycle such as number of factors, complexity of processes, magnitude of impact, etc. It serves to sum up the integration of nature and anthropogenic water cycle, in the form of a bi-modal urban water cycle model. The work focuses on the difference and compatibility of scales and methodology in urban hydrological processes, in order to highlight the gaps in urban water cycle research. This includes developing a unique model to simulate the characteristics and evolution of processes in urban areas, with the intention of supporting future urban water resources management.

“…Water is also an essential input in such production processes. Previous studies about water resources have examined the value or price of water consumption [1][2][3]. First, in industrial water consumption, Ku et al [4] calculated the output elasticity and value of industrial water on the basis of data on 53,912 manufacturing firms in Korea, Mejías et al [5] evaluated the efficiency of industrial water-charging systems in Spain and Ireland.…”

a b s t r a c tWater is one of the essential resources to production and living. Agriculture, industry, and living are considered as the direct water consumption. This paper employs the concept of marginal product value to estimate the water consumption marginal benefits in Henan Province. We use data on agricultural water consumption, industrial water consumption, and domestic water consumption of 18 cities in Henan Province surveyed from 2006 to 2013 and considered the Cobb-Douglas production function. The results showed that, during the study period, except for the marginal benefit of agriculture in high developed area, the industrial and domestic water use increased, and the industrial and domestic water use benefits were much higher than agricultural. At the same time, the benefit of the developed area was higher than the developing area. The benefits of agricultural water consumption and industrial water consumption in high developed area have made great improvements gradually, while benefits in low developed area have made small changes; but the benefits of domestic water consumption presented the opposite trend. For the moment, the water consumption marginal benefit still has climbing space. The results are needed for determining the ways in which scarce water resources could be assigned to different areas and sectors.
