“…It is becoming popular amongst growers because of its multifunctional use and uses such as food for humans, raw materials for various industries and animal feed. Grain is a good fat, minerals, starch, protein, vitamin source (Khan et al, 2012;Toum et al, 2018). Maize has an important nutrient value with about 72% starch, protein approximately 10%, and fiber up to 12% and oils approximately 3% (Ali et al, 2014).…”

T HE MAXIMUM requirement of primary nutrients by hybrid maize crop deteriorate the fertility of soil, therefore farm yard manure (FYM) in combination with mineral zinc (Zn) and phosphorus (P) was selected for the increasing crop productivity, rehabilitate and sustain the precious soil. The research was carried out at the farm of the university of Agriculture Peshawar (UAP)during year 2019-20.To investigate the impact of mineral P from di-ammonium phosphate (DAP) and Zn from zinc sulphate (ZnSO 4 ) in combination with FYM on maize yield. The experiment was carried out in randomized completed block design (RCND) having eight different combinations of FYM, P and Zn were used excluding control. Spring hybrid variety of maize (CS-200) was used as a test crop. Basal dosage of nitrogen (N) 120 and potassium (K) 60 kg ha -1 were also applied. Physio-chemical properties of soil and concentration of Zn, P and K in maize leaves at silking stage and post harvested stage were measured. The objectives of this study was to determine the impact of FYM, P and (Zn) alone and in combination on yield of maize and soil properties and to gives best combination of organic fertilizers with mineral. From this research it was concluded that the combine application mineral P and Zn with FYM have linearly influenced the thousand grains weight, grain and biological yield of hybrid maize . The combine used of P and FYM @ of 90 kg ha -1 and 10 ton ha -1 shows influential impact on 1000 grains weight and grain yield, respectively. The soil organic matter and total N were significantly (P≤0.05) influenced by FYM applied alone, whereas the uptake of N, P and K by hybrid maize crop was found maximum in the plot where P in combination with FYM was added. Based on results the application of FYM @ 10 t ha -1 applied with 90 kg P ha -1 have the potential to improve maize yield as well as soil fertility and physical condition, also enhance the plant nutrient uptake and yield of hybrid maize, while the concentration of zinc in soil and plant were also greatly affected by the applied treatment. It shows antagonistic effect with P and its concentration become linearly decreased with the increase in P rates, while the maximum Zn concentration was showed by the sole application of zinc fertilizer.

In this paper, a quantifiable method for risk evaluation of water conservancy ina publicprivate partnership (PP) PPP project is presented. Firstly, according to the characteristics of water conservancy PPP project, a risk evaluation index was determined by Delphi method and literature collection method; secondly, the weight of risk evaluation indexes were determined by rank correlation analysis; thirdly, based on grey fuzzy theory, a grey fuzzy comprehensive evaluation model was constructed, and uncertain grey and fuzzy contents were transformed into values that can be accurately measured, which provided a basis for managers to make decisions. Finally, the grey fuzzy comprehensive evaluation model was applied to Fendou Reservoir, a water conservancy PPP project, and it proved to be reasonable and scientific.

“…The 3D model was initially proposed by a group researcher, and the model was introduced and optimized by the Chinese scholar Fang Kai before being widely studied and applied (Niccolucci et al 2012, Borogayary et al 2018, Pe'Eri et al 2016, Ahamed et al 2017, Cheung et al 2017. Some researchers adopted the model to measure the natural capital of Beijing-Tianjin-Hebei urban agglomeration (Du et al 2016, Yun et al 2018, Toum et al 2018. In other studies, researchers extended the 3D ecological footprint model to study the land carrying capacity of the Wenzhou City, and this paper attempts to build on the 3D ecological footprint model (Jin and Liu 2017).…”

Based on the three-dimensional (3D) ecological footprint model, this paper has provided the measurements of the dynamic changes of the 3D ecological footprint of Shenyang from 2005 to 2016, and the analysis of the driving factors behind such footprint through the partial least-squares regression. Our research findings reveal that: The overall per capita 3D ecological footprint of the Shenyang City went upward from 2005 to 2016, with an average annual growth rate of 16.5%; at the meantime, the per capita ecological carrying capacity showed a year-on-year downward trend at an average annual rate of 0.79%. The analysis of partial least squares regression indicates that urban ecological construction and environmental pollution constitute the significant factors that lead to the increase of the ecological footprint year by year in Shenyang. On the contrary, the exchange and trade, the environmental governance and the structure of land use are conducive to relieving the pressure on the ecological expansion. Our analysis of the importance of variable projections demonstrates that per capita public green area and the emission indicators of the industrial waste have imposed a greater influence on the index of ecological footprint of Shenyang and are relatively consistent with the comprehensive evaluation results of the regression analysis. In the future, we shall enhance the efficiency of urban ecological construction by optimizing industrial structure, using clean energy, actively developing foreign trade and exchanges, and rationally planning urban land use.
