“…Consequently, the crop water requirement can be obtained by firstly calculating reference crop evapotranspiration (ET0) and then correction by the crop coefficient (Kc). The Penman-Monteith method is widely applied in calculating ET0 [7,14,15], and it is featured by wide range of application and reliable calculation results [13,16,17]. Many previous studies have been conducted to estimate crop water requirement per unit area [8,9,18].…”

Irrigation water demand accounts for more than 95% of the total water use in the Kaidu-kongqi River Basin. Determination of the spatial and temporal trends in irrigation water demand is important for making sustainable and wise water management strategies in this highly water deficit region. In this study, the spatial and temporal trends in irrigation water demand as well as net crop irrigation water requirements for nine major crops during 1985-2009 were analyzed by combining the Penman-Monteith equation recommended by Food and Agriculture Organization (FAO) and GIS technology. The regional water stress was also evaluated based on the total irrigation water demand and river discharge at the annual and monthly scales. The results indicated that the annual irrigation water demand in this arid region showed a significant increasing trend during the past 25 years. Total irrigation water demand increased from 14.68 × 10 . The spatial pattern of total irrigation water demand was significantly affected by the changes in cotton growing area. Due to differences in crop planting structure, the monthly average irrigation water demands in Korla City and Yuli County amounted to the peak in July, while those in other regions reached the maximum in June. Although the annual river runoff was much larger than the irrigation water demand, there was serious water deficit during the critical water use period in May and June in some dry years. The presented study OPEN ACCESSSustainability 2015, 7 12959 provides important information for managers and planners on sustainable use of water resources in this arid region.

“…The development of irrigation schedules and evaluation of rainfed and irrigation practices are based on a daily soil-moisture balance using various options for water supply and irrigationmanagement conditions. Scheme water supply is calculated according to the cropping pattern provided inthe program (7). Studies have shown that the Penman-Monteith method is more reliable than methods that use less climatic data (8).…”

:Water scarcity is a real threat to food production for millions of people in arid and semiarid areas. Due to the over use of available water resources, it has become very important to define appropriate strategiesfor planning and management of irrigated farmland. In this paper, Kenana-Sennar -New Halfa (Sugar cane) region was chosen as the case study area for its special political and economic status and its severe water problem. To achieve effectiveplanning, the information about crop water requirements, irrigation withdrawals, soil types and climatic conditions had beenobtained in the study area. In the meantime, a GIS had been adopted, which extends the capabilities of the crop modelsto a regional level. The Sugar cane region has seasonal water deficits, seriously in Sugar cane germination stage, which is the dominating reason for the low yield per unit area in this region. Under the fortnightly precipitation scenario, in Kenana irrigation was recommended two times in its growth period: 7May and 21May respectively. In Sennar irrigation was also recommended seven times:7 May, 21May, 4June, 18June, 2July , 16July and 27 August respectively. In New Halfa irrigation was recommended nine: 7May, 21May, 4June, 18June, 2July, 16 July, 30 July, 13 August and 27 August Keywords: Sugar Cane , Climatic Water Deficit, Irrigation scheduling I. INTRODUCTION In the near future, irrigated agriculture will need to produce two-thirds of the increase in food products required by a large population increase(1).The growing dependence on irrigated agriculture coincides with an accelerated competition for water and increased awareness of unintended negative consequences of poor design and management. Irrigation systems are selected, designed and operated to supply the individual irrigation requirements of each crop field on the farm while controlling deep percolation, runoff, evaporation and operational losses to establish a sustainable production process. Considering the stupendous task and constraint of time in developing the ultimate irrigation potential, it is necessary to use the modern methods of surveying and analysis tools. Remote sensing and Geographic Information System (GIS) with their capabilities of data collection, manipulation, integration, analysis, presentation, dissemination etc.These systems become more efficient and effective tools for irrigation water management.The capability of GIS to analyze the information across space and time would help in managing such dynamic systems. Soil survey data and GIS are important tools in land use planning. Intertwined, they represent an invaluable and underutilized resource. (2)found that the GIS is an important tool that can be used for optimal allocation of water resources of an irrigation project. Mean water balance components results for different months were stored in GIS databases, analyzed and displayed as the monthly crop water requirements maps. (3)showed that satellite remote sensing coupled with GIS offers an excellent alternative to conventional mapping t...

“…Such an "agro-centric rain" analysis would seek to understand the amounts and timing of rain events with respect to the water needs of the crop, as determined by its growth and development within a defined management system. An agro-centric rain analysis, carried out for a given region over a series of years might provide insight into the types of crop management systems that will allow producers to optimize the crop production within a given environment [1,2].…”

“…Relevant questions include: (1) Is there a more favorable rain environment associated with of a given potential cotton crop season relative to another? (2) What is the potential advantage of shifting low temperatures to the beginning of a crop season compared to having them occur later in the season? (3) Is there a variety more suited to one potential cotton crop season compared to another?…”

Rain is the major limiter of cotton yields on the Southern High Plains of Texas. Rain can be analyzed in terms of its effect on the crop. An "agro-centric rain" analysis assesses the amounts and timing of rain events within a defined management system. Cotton on the Southern High Plains of Texas at Lubbock, TX, USA was analyzed in terms of the crop water environment associated with 70 potential cotton crop seasons over the period from 2006 to 2015. For the 10-year period, the 238-day cotton growing season was divided into seven potential cotton crop seasons of 154-days each. Rain and crop water status (as reference and crop evapotranspiration) were calculated for each of the 70 potential cotton crop seasons. The highest rain amounts were associated with earlier plantings. Maximum values of reference evapotranspiration were associated with the mid-season plantings and minimum values with the earliest and latest plantings. Crop stress (rain-reference evapotranspiration) showed a pattern with maximum stress associated with the earliest plantings. Crop water status across potential cotton crop seasons can vary with planting date across years and it may be possible to exploit the variation to improve yield in terms of germplasm and management practices.
