Irtysh Basin

Results of the comprehensive water/resources and ecological researchers of the OB-Irtysh basin current state are given. Assessment of the many-year dynamics of the main indicators characterizing the Ob River ecological status has been made. The data are quoted on the basis of the analysis of materials of many-year hydrological, hydro/chemical, ecological and water/economic researchers of Russian Academy of Sciences Siberian Branch Institute of Water and Ecological Problems. The main problems of water supply and water use special for this basin have been revealed: non-uniformity of water resources distribution, hazardous hydrological phenomena (inundation, flooding, and channel processes), as well as water pollution (of human and natural origin). The situation is aggravated by the Ob-Irtysh basin transboundary status. The anthropogenic transformation of the region has been estimated: its index is the highest in the steppe and Southern forest/steppe areas of the Ob-Urtysh basin, while it is much lower in the Northern part of the basin; in mountain areas of Altay, Salair and Kuznetsk Alatau anthropogenic transformation is not high, and in the regions of Transuralia and Kuznetsk depression the territories of environmental problems have been identified. Non-synchronism of water content changes many-year trends for different parts of the basin has been revealed. Over the past decades volumes of water use and water disposal somewhat decreased in respect of the whole basin. Bearing in mind the level of groundwater and surface water resources availability, 15% of the total population of the Ob-Irtysh basin live in the conditions of extremely low and very low potential water supply. New data obtained as a result of comprehensive expedition water/ecological researches in 2016 with the use of research fleet are quoted.

Drought conditions make landscape irrigation and reducing water use top-of-mind for many Floridians. Encouraging wise water use is of particular importance to the smart irrigation industry and water policy makers. This 5-page fact sheet written by Hayk Khachatryan, Alicia Rihn, Dong Hee Suh, and Michael Dukes and published by the UF/IFAS Food and Resource Economics Department pinpoints key attributes and barriers affecting consumers' irrigation purchases and their adoption of smart irrigation technologies. https://edis.ifas.ufl.edu/fe1080

Boro Rice

Utilization of urea super granule (USG) with raised bed cultivation system for transplanted boro (winter, irrigated) rice production is a major concern now days. A field experiment was conducted in the chuadanga district of Bangladesh to compare the two cultivation methods: deep placement of USG on raised bed with boro rice, and prilled urea (PU) broadcasting in conventional planting. Results showed that USG in raised bed planting increased grain yields of transplanted boro rice by up to 18.18% over PU in conventional planting. Deep placement of USG in raised bed planting increased the number of panicle m-2, number of grains panicle-1 and 1000-grains weight of boro rice than the PU in conventional planting. Better plant growth was observed by deep placement of USG in raised bed planting compared to PU in conventional planting. Sterility percentage and weed infestation were lower on USG in raised bed planting compared to the PU in conventional planting methods. Forty seven percent irrigation water and application time could be saved by USG in raised bed planting than PU in conventional planting. Deep placement of USG in bed saved N fertilizer consumption over conventional planting. Water use efficiency for grain and biomass production was higher with deep placement of USG in bed planting than the PU broadcasting in conventional planting methods. Similarly, agronomic efficiency of N fertilizer by USG in bed planting was significantly higher than the PU broadcasting in conventional planting. This study concluded that deep placement of USG in raised bed planting for transplanted boro rice is a new approach to achieve fertilizer and water use efficiency as well as higher yield and less water input compared to existing agronomic practices in Bangladesh.
