“…The profit reflected the net economic gain equal to the difference between income and production costs (Younis et al, 1991;Kendall et al, 2007;El-Waheda and Ali, 2013;Kresović et al, 2014):…”

“…The income earned from potato production and the associated production costs were calculated and shown for rainfed conditions, sprinkler irrigation and SDI. Income was the product of the marketable tuber yield and prevailing market prices (Kendall et al, 2007;El-Waheda and Ali, 2013;Kresović et al, 2014;Weligamage et al, 2014) ( Table II).…”

The present research was conducted during the dry and warm growing seasons of 2011, 2012 and 2013 at Guča, which is a well-known potato-growing region of Serbia. Potato was grown under both rainfed conditions and with irrigation, applying two methods: sprinkler and subsurface drip irrigation. The objective of the research was to conduct a comparative analysis and assess the profitability of potato production under rainfed conditions and with irrigation by these two methods. The main outcome of the research showed that higher yields and more profitable production are achievable with irrigation, compared to rainfed conditions. Subsurface drip irrigation was found to be more profitable than sprinkler irrigation. The results provided insight into the structure and distribution of income and expenses, the income and expense growth trend, the percentage profit growth in the case of sprinkler and subsurface drip irrigation, as well as potential income losses at the national level if the irrigation methods considered are not used. A detailed analysis of the production costs provided insight into the feasibility of optimizing potato-growing approaches for all three types of production. The higher profitability of irrigated potato production opens the question of the need to increase irrigation coverage in Serbia. Copyright © 2016 John Wiley & Sons, Ltd. RÉSUMÉLa présente recherche a été menée au cours des saisons de croissance des périodes chaudes et sèches des années 2011, 2012 et 2013 à Guča, une région de la Serbie bien connue pour la culture de la pomme de terre. La pomme de terre a été cultivée sous conditions pluviales et irriguées. Deux techniques d'irrigation sont utilisées: par aspersion et par goutte-à-goutte enterré. L'objectif de cette étude était de réaliser une analyse comparative et d'évaluer la rentabilité de la production de la culture de la pomme de terre en condition pluviale et par les deux techniques d'irrigation. Les résultats principaux de cette étude ont montré qu'un rendement plus élevé et une production plus rentable sont réalisables en conditions irriguées par rapport aux conditions pluviales. L'irrigation au goutte à goutte enterrée a été trouvée être plus rentable que l'irrigation par aspersion. Les résultats ont fourni un aperçu de la structure et de la répartition des revenus et des dépenses, la tendance de la croissance des revenus et des dépenses, la croissance de la marge bénéficiaire dans l'irrigation par aspersion et l'irrigation au goutte à goutte enterrée, ainsi que les pertes de revenus potentiels au niveau national si les techniques d'irrigation choisies ne sont pas utilisées. Une analyse détaillée des coûts de production a donné un aperçu sur la faisabilité de la croissance de l'approche d'optimisation de la culture de la pomme de terre pour les trois types de production. La rentabilité plus élevée de la production de la pomme de terre irriguée ouvre la question de la nécessité d'accroître la couverture de l'irrigation en Serbie.

“…Drip irrigation proves its superiority over other methods of irrigation due to the direct application of water and nutrients in the vicinity of the root zone. Abd El-Wahed and Ali (2013) showed that the drip irrigation system maximized maize grain yield and water use efficiency compared to the sprinkler irrigation system. The highest values of grain yield and water use efficiency were recorded for plants irrigated with 100% of the crop evapotranspiration (Etc).…”

A b s t r a c t. Field experiments was conducted to determine the best irrigation scheduling and the proper period for injecting fertilizers through drip irrigation water in a sandy soil to optimize maize yield and water productivity. Four irrigation levels (0.6, 0.8, 1.0 and 1.2) of the crop evapotranspiration and two fertigation periods (applying the recommended fertilizer dose in 60 and 80% of the irrigation time) were applied in a split-plot design, in addition to a control treatment which represented conventional irrigation and fertilization of maize in the studied area. The results showed that increasing the irrigation water amount and the fertilizer application period increased vegetative growth and yield. The highest grain yield and the lowest one were obtained under the treatment at 1.2 and of 0.6 crop evapotranspiration, respectively. The treatment at 0.8 crop evapotranspiration with fertilizer application in 80% of the irrigation time gave the highest water productivity (1.631 kg m -3 ) and saved 27% of the irrigation water compared to the control treatment. Therefore, this treatment is recommended to irrigate maize crops because of the water scarcity conditions of the studied area.

“…After analysis and calculation of 459 irrigated areas' water productivity indices of China in Cao's paper, it is shown that almost all of the provincial water productivity increased from 1998 to 2010 in time and space. According to the summary of the literature, commonly used evaluation indicators of water use efficiency are: irrigation water use efficiency and water productivity [5], virtual water content and water footprint [6,7], and water profit [8]. Second aspect is the research on the evaluation methods of water use efficiency.…”

Jiangsu is a major province located in the east of China, consuming a large amount of water resources. It is considered that improving the comprehensive water use efficiency has an important significance to achieve sustainable development of the economy in Jiangsu. Through extensive literature research and investigation of Jiangsu Province, this paper establishes comprehensive water use efficiency index system using water consumption per ten thousand dollar gross domestic product (WC/$10 4 GDP) as the research target. In the index system, resource factors such as surface water resources (SW), groundwater resources (GW), precipitation (PT), water resources per capita (PW), water consumption per capita (PC) and irrigation area per capita (PI) cannot be artificially altered. Furthermore, the variation amplitude of resource factors is very small. It shows that the linear regression model is not suitable to analyze the resource factors by changing the independent variables. In view of this situation, this paper introduces impulse response function on the basis of vector autoregressive model (VAR) to investigate the intrinsic link between resource factors and WC/$10 4 GDP in Jiangsu Province. The results show that resource factors have a great impact on WC/$10 4 GDP in Jiangsu, and the per capita water resources (PW) has the most significant impact.
